HomeMy WebLinkAboutItem 06.c Date: December 2, 2019 Item No. ADOPTION OF THE LAKEVILLE WATER SUPPLY PLAN Proposed Action Staff recommends adoption of the following motion: Move to adopt the Lakeville Water Supply Plan. Overview Public water suppliers serving more than 1,000 people, large private water suppliers in designated Groundwater Management Areas, and all water suppliers in the Twin Cities metropolitan area are required to prepare and submit a water supply plan for approval to the Department of Natural Resources. Water supply plans are updated every 10 years. The goal of the water supply plan is to help water suppliers prepare for droughts and water emergencies and fulfill contingency plan provisions contained in the wellhead protection and surface water protection plans. A key benefit to completion of the plan is to allow water suppliers to submit requests for new wells or expand capacity in existing wells. Implementation of the plan contributes to maintaining aquifer levels, reducing potential well interference and water use conflicts, and reducing the need to drill new wells or expand system capability prematurely. The plan was submitted to DNR in December 2016, returned with comments in June 2019, and approved in November 2019. Primary Issues to Consider • Why do we complete a water supply plan? First, it is required by state statute. Beyond that, it is a planning tool used by both the City and DNR to evaluate usage and demand trends and plan for future needs based on population growth. It facilitates a review by the City of emergency procedures in case of a water shortage and it focuses the City on methods to encourage more efficient use of this finite resource. The water supply plan is the basis for the Comprehensive Water Plan included in the City’s comprehensive plan. Supporting Information • A copy of the water supply plan and a certificate of adoption of the water supply plan are attached.

The goal of the WSP is to help water suppliers: 1) implement long term water sustainability and conservation measures; and 2) develop critical emergency preparedness measures. Your community needs to know what measures will be implemented in case of a water crisis. A lot of emergencies can be avoided or mitigated if long term sustainability measures are implemented. Groundwater Management Areas (GWMA) The DNR has designated three areas of the state as Groundwater Management Areas (GWMAs) to focus groundwater management efforts in specific geographies where there is an added risk of overuse or water quality degradation. A plan directing the DNRs actions within each GWMA has been prepared. Although there are no specific additional requirements with respect to the water supply planning for communities within designated GWMAs, communities should be aware of the issues and actions planned if they are within the boundary of one of the GWMAs. The three GWMAs are the North and East Metro GWMA (Twin Cities Metro), the Bonanza Valley GWMA and the Straight River GWMA (near Park Rapids). Additional information and maps are included in the DNR webpage at http://www.dnr.state.mn.us/gwmp/areas.html Benefits of completing a WSP Completing a WSP using this template, fulfills a water supplier’s statutory obligations under M.S. M.S.103G.291 to complete a water supply plan. For water suppliers in the metropolitan area, the WSP will help local governmental units to fulfill their requirements under M.S. 473.859 to complete a local comprehensive plan. Additional benefits of completing WSP template: • The standardized format allows for quicker and easier review and approval. • Help water suppliers prepare for droughts and water emergencies. • Create eligibility for funding requests to the Minnesota Department of Health (MDH) for the Drinking Water Revolving Fund. • Allow water suppliers to submit requests for new wells or expanded capacity of existing wells. • Simplify the development of county comprehensive water plans and watershed plans. • Fulfill the contingency plan provisions required in the MDH wellhead protection and surface water protection plans. • Fulfill the demand reduction requirements of Minnesota Statutes, section 103G.291 subd 3 and 4. 2 • Upon implementation, contribute to maintaining aquifer levels, reducing potential well interference and water use conflicts, and reducing the need to drill new wells or expand system capacity. • Enable DNR to compile and analyze water use and conservation data to help guide decisions. • Conserve Minnesota’s water resources If your community needs assistance completing the Water Supply Plan, assistance is available from your area hydrologist or groundwater specialist, the MN Rural Waters Association circuit rider program, or in the metropolitan area from Metropolitan Council staff. Many private consultants are also available. WSP Approval Process 10 Basic Steps for completing a 10-Year Water Supply Plan 1. Download the DNR/Metropolitan Council Water Supply Plan Template www.mndnr.gov/watersupplyplans 2. Save the document with a file name with this naming convention: WSP_cityname_permitnumber_date.doc. 3. The template is a form that should be completed electronically. 4. Compile the required water use data (Part 1) and emergency procedures information (Part 2) 5. The Water Conservation section (Part 3) may need discussion with the water department, council, or planning commission, if your community does not already have an active water conservation program. 6. Communities in the seven-county Twin Cities metropolitan area should complete all the information discussed in Part 4. The Metropolitan Council has additional guidance information on their webpage http://www.metrocouncil.org/Handbook/Plan-Elements/Water- Resources/Water-Supply.aspx. All out-state water suppliers do not need to complete the content addressed in Part 4. 7. Use the Plan instructions and Checklist document to insure all data is complete and attachments are included.

Discuss the difference between current storage and treatment capacity versus the water supplier’s projected average water demand over the next 10 years (see Table 7 for projected water demand): Based on expected population growth, Lakeville has sufficient storage and treatment capacity to meet expected average daily demand. C. Water Sources Complete Table 6 by listing all types of water sources that supply water to the system, including groundwater, surface water, interconnections with other water suppliers, or others. Provide the name of each source (aquifer name, river or lake name, name of interconnecting water supplier) and the Minnesota unique well number or intake ID, as appropriate. Report the year the source was installed or established and the current capacity. Provide information about the depth of all wells. Describe the status of the source (active, inactive, emergency only, retail/wholesale interconnection) and if the source facilities have a dedicated emergency power source. Add rows to the table as needed for each installation. Include copies of well records and maintenance summary for each well that has occurred since your last approved plan in Appendix 1. 8 Table 6.

If there are no limitations, list none. Well 18 (745558) is limited to 500 GPM due to flow within aquifer. Use of interconnections with Burnsville, Apple Valley, and Farmington are limited by water pressure. Apple Valley and Farmington can only feed a portion of the low-pressure system in Lakeville. Burnsville can only feed the high pressure system but requires that Lakeville lower its tower levels 8 to 11 feet. D. Future Demand Projections – Key Metropolitan Council Benchmark Water Use Trends Use the data in Table 2 to describe trends in 1) population served; 2) total per capita water demand; 3) average daily demand; 4) maximum daily demand. Then explain the causes for upward or downward trends. For example, over the ten years has the average daily demand trended up or down? Why is this occurring? Lakeville continues to be a growing community. Population has expanded by more the 8,300 people in the last 10 years and, based on housing starts, will continue to grow at that pace for the foreseeable future. Currently, Lakeville population is at about 70 percent of the total population projected by the Metropolitan Council. 9 In spite of this continuing growth, all other indicators are either trending down or remaining flat based on data for the last ten years. Key among those indicators are total water delivered, total water pumped, and average daily demand which have all remained flat and residential and total per capita use with both show a downward trend. Weather factors have played a role in Lakeville’s water consumption. Drier, hotter years have seen increases in pumping totals and per capita consumption tied primarily to residential irrigation systems. The City’s odd/even and time of day watering restriction have minimized the impact of those increases on the water system and have led, after several years of customer education to a general decline in those consumption rates. However, the return of a hot and dry year could well reverse, in the short term, existing downward trends. Use the water use trend information discussed above to complete Table 7 with projected annual demand for the next ten years. Communities in the seven-county Twin Cities metropolitan area must also include projections for 2030 and 2040 as part of their local comprehensive planning. Projected demand should be consistent with trends evident in the historical data in Table 2, as discussed above. Projected demand should also reflect state demographer population projections and/or other planning projections. Table 7.

A 10 average was used as better depicting impacts of weather and 10 population growth. Shorter term averages are more susceptible to extremes in weather. The maximum day demand is projected using a peaking factor of 2.5 which is the average of the previous 5 years. The projected demand rates represent an average to high water use year for the projected population and likely a summer with lower rainfall and higher temperatures. E.

Emergency Preparedness Procedures The emergency preparedness procedures outlined in this plan are intended to comply with the contingency plan provisions required by MDH in the WHP and SWP. Water emergencies can occur as a result of vandalism, sabotage, accidental contamination, mechanical problems, power failings, drought, flooding, and other natural disasters. The purpose of emergency planning is to develop emergency response procedures and to identify actions needed to improve emergency preparedness. In the case of a municipality, these procedures should be in support of, and part of, an all-hazard emergency operations plan. Municipalities that already have written procedures dealing with water emergencies should review the following information and update existing procedures to address these water supply protection measures. A. Federal Emergency Response Plan Section 1433(b) of the Safe Drinking Water Act, (Public Law 107-188, Title IV- Drinking Water Security and Safety) requires community water suppliers serving over 3,300 people to prepare an Emergency Response Plan. Do you have a federal emergency response plan? Yes ☒ No ☐ If yes, what was the date it was certified? September 7, 2011 Complete Table 15 by inserting the noted information regarding your completed Federal Emergency Response Plan. Table 15.

Operational Contingency Plan All utilities should have a written operational contingency plan that describes measures to be taken for water supply mainline breaks and other common system failures as well as routine maintenance. Do you have a written operational contingency plan? Yes ☐ No ☒ At a minimum, a water supplier should prepare and maintain an emergency contact list of contractors and suppliers. C. Emergency Response Procedures Water suppliers must meet the requirements of MN Rules 4720.5280 . Accordingly, the Minnesota Department of Natural Resources (DNR) requires public water suppliers serving more than 1,000 people to submit Emergency and Conservation Plans. Water emergency and conservation plans that have been approved by the DNR, under provisions of Minnesota Statute 186 and Minnesota Rules, part 6115.0770, will be considered equivalent to an approved WHP contingency plan. 22 Emergency Telephone List Prepare and attach a list of emergency contacts, including the MN Duty Officer (1-800-422-0798), as Appendix 5. A template is available at www.mndnr.gov/watersupplyplans The list should include key utility and community personnel, contacts in adjacent water suppliers, and appropriate local, state and federal emergency contacts. Please be sure to verify and update the contacts on the emergency telephone list and date it. Thereafter, update on a regular basis (once a year is recommended). In the case of a municipality, this information should be contained in a notification and warning standard operating procedure maintained by the Emergency Manager for that community. Responsibilities and services for each contact should be defined. Current Water Sources and Service Area Quick access to concise and detailed information on water sources, water treatment, and the distribution system may be needed in an emergency. System operation and maintenance records should be maintained in secured central and back-up locations so that the records are accessible for emergency purposes. A detailed map of the system showing the treatment plants, water sources, storage facilities, supply lines, interconnections, and other information that would be useful in an emergency should also be readily available. It is critical that public water supplier representatives and emergency response personnel communicate about the response procedures and be able to easily obtain this kind of information both in electronic and hard copy formats (in case of a power outage). Do records and maps exist? Yes ☒ No ☐ Can staff access records and maps from a central secured location in the event of an emergency? Yes ☒ No ☐ Does the appropriate staff know where the materials are located? Yes ☒ No ☐ Procedure for Augmenting Water Supplies Complete Tables 16 – 17 by listing all available sources of water that can be used to augment or replace existing sources in an emergency. Add rows to the tables as needed. In the case of a municipality, this information should be contained in a notification and warning standard operating procedure maintained by the warning point for that community. Municipalities are encouraged to execute cooperative agreements for potential emergency water services and copies should be included in Appendix 6. Outstate Communities may consider using nearby high capacity wells (industry, golf course) as emergency water sources. WSP should include information on any physical or chemical problems that may limit interconnections to other sources of water. Approvals from the MDH are required for interconnections or the reuse of water. 23 Table 16.

Provide information for each customer category, including its priority ranking, average day demand, and demand reduction potential for each customer category. Modify the customer categories as needed, and add additional lines if necessary. Water use categories should be prioritized in a way that is consistent with Minnesota Statutes 103G.261 (#1 is highest priority) as follows: 1. Water use for human needs such as cooking, cleaning, drinking, washing and waste disposal; use for on-farm livestock watering; and use for power production that meets contingency requirements. 2. Water use involving consumption of less than 10,000 gallons per day (usually from private wells or surface water intakes) 3. Water use for agricultural irrigation and processing of agricultural products involving consumption of more than 10,000 gallons per day (usually from private high-capacity wells or surface water intakes) 24 4. Water use for power production above the use provided for in the contingency plan. 5. All other water use involving consumption of more than 10,000 gallons per day. 6. Nonessential uses – car washes, golf courses, etc. Water used for human needs at hospitals, nursing homes and similar types of facilities should be designated as a high priority to be maintained in an emergency. Lower priority uses will need to address water used for human needs at other types of facilities such as hotels, office buildings, and manufacturing plants. The volume of water and other types of water uses at these facilities must be carefully considered. After reviewing the data, common sense should dictate local allocation priorities to protect domestic requirements over certain types of economic needs. Water use for lawn sprinkling, vehicle washing, golf courses, and recreation are legislatively considered non-essential. Table 18. Water use priorities Customer Category Allocation Priority Average Daily Demand (GPD) Short-Term Emergency Demand Reduction Potential (GPD) Residential 1 4,484,501 1,000,000 Institutional 2 148,444 0 Commercial 3 380,490 0 Industrial 4 186,136 0 Irrigation 5 561,567 561,567 Wholesale NA 0 0 Non-Essential 6 200,000 200,000 TOTAL NA 5,961,138 1,761,567 GPD – Gallons per Day Tip: Calculating Emergency Demand Reduction Potential The emergency demand reduction potential for all uses will typically equal the difference between maximum use (summer demand) and base use (winter demand). In extreme emergency situations, lower priority water uses must be restricted or eliminated to protect priority domestic water requirements. Emergency demand reduction potential should be based on average day demands for customer categories within each priority class. Use the tables in Part 3 on water conservation to help you determine strategies. Complete Table 19 by selecting the triggers and actions during water supply disruption conditions. 25 Table 19.

The enforcement response plan must outline how conditions will be monitored to know when enforcement actions are triggered, what enforcement tools will be used, who will be responsible for enforcement, and what timelines for corrective actions will be expected. Affected operations, communications, and enforcement staff must then be trained to rapidly implement those provisions during emergency conditions. Important Note: Disregard of critical water deficiency orders, even though total appropriation remains less than permitted, is adequate grounds for immediate modification of a public water supply authority’s water use permit (2013 MN Statutes 103G.291) Does the city have a critical water deficiency restriction/official control in place that includes provisions to restrict water use and enforce the restrictions? (This restriction may be an ordinance, rule, regulation, policy under a council directive, or other official control) Yes ☒ No ☐ If yes, attach the official control document to this WSP as Appendix 7. If no, the municipality must adopt such an official control within 6 months of submitting this WSP and submit it to the DNR as an amendment to this WSP. Irrespective of whether a critical water deficiency control is in place, does the public water supply utility, city manager, mayor, or emergency manager have standing authority to implement water restrictions? Yes ☒ No ☐ If yes, cite the regulatory authority reference: Lakeville City Ordinance 7-5-12-1. If no, who has authority to implement water use restrictions in an emergency? 27 Priority 1: Significant water reduction; low cost Priority 2: Slight water reduction, low costs (low hanging fruit) Priority 2: Significant water reduction; significant costs Priority 3: Slight water reduction, significant costs (do only if necessary) PART 3. WATER CONSERVATION PLAN Minnesotans have historically benefited from the state’s abundant water supplies, reducing the need for conservation. There are however, limits to the available supplies of water and increasing threats to the quality of our drinking water. Causes of water supply limitation may include: population increases, economic trends, uneven statewide availability of groundwater, climatic changes, and degraded water quality. Examples of threats to drinking water quality include: the presence of contaminant plumes from past land use activities, exceedances of water quality standards from natural and human sources, contaminants of emerging concern, and increasing pollutant trends from nonpoint sources. There are many incentives for conserving water; conservation: • reduces the potential for pumping-induced transfer of contaminants into the deeper aquifers, which can add treatment costs • reduces the need for capital projects to expand system capacity • reduces the likelihood of water use conflicts, like well interference, aquatic habitat loss, and declining lake levels • conserves energy, because less energy is needed to extract, treat and distribute water (and less energy production also conserves water since water is use to produce energy) • maintains water supplies that can then be available during times of drought It is therefore imperative that water suppliers implement water conservation plans. The first step in water conservation is identifying opportunities for behavioral or engineering changes that could be made to reduce water use by conducting a thorough analysis of: • Water use by customer • Extraction, treatment, distribution and irrigation system efficiencies • Industrial processing system efficiencies • Regulatory and barriers to conservation • Cultural barriers to conservation • Water reuse opportunities Once accurate data is compiled, water suppliers can set achievable goals for reducing water use. A successful water conservation plan follows a logical sequence of events. The plan should address both conservation on the supply side (leak detection and repairs, metering), as well as on the demand side (reductions in usage). Implementation should be conducted in phases, starting with the most obvious and lowest-cost options. In some cases one of the early steps will be reviewing regulatory constraints to water conservation, such as lawn irrigation requirements. Outside funding and grants may be available for implementation of projects. Engage water system operators and maintenance staff and customers in brainstorming opportunities to reduce water use. Ask the question: “How can I help save water?” Progress since 2006 Is this your community’s first Water Supply Plan? Yes ☐ No ☒ 28 If yes, describe conservation practices that you are already implementing, such as: pricing, system improvements, education, regulation, appliance retrofitting, enforcement, etc. If no, complete Table 21 to summarize conservation actions taken since the adoption of the 2006 water supply plan. Table 21. Implementation of previous ten-year Conservation Plan 2006 Plan Commitments Action Taken? Change water rates structure to provide conservation pricing ☒ Yes ☐ No Water supply system improvements (e.g. leak repairs, valve replacements, etc.) ☒ Yes ☐ No Educational efforts ☒ Yes ☐ No New water conservation ordinances ☐ Yes ☒ No Rebate or retrofitting Program (e.g. for toilet, faucets, appliances, showerheads, dish washers, washing machines, irrigation systems, rain barrels, water softeners, etc. ☐ Yes ☒ No Enforcement ☒ Yes ☐ No Describe other ☐ Yes ☐ No What are the results you have seen from the actions in Table 21 and how were results measured? As the City continues to grow, 10 year trends have shown little to no increase in per capita water use. Educational efforts with local schools and to the community at large have been extremely important in informing customers of the importance of conservation in preserving the City’s water resources. A. Triggers for Allocation and Demand Reduction Actions Complete table 22 by checking each trigger below, as appropriate, and the actions to be taken at various levels or stages of severity. Add in additional rows to the table as needed. 29 Table 22.

B. Conservation Objectives and Strategies – Key benchmark for DNR This section establishes water conservation objectives and strategies for eight major areas of water use. Objective 1: Reduce Unaccounted (Non-Revenue) Water loss to Less than 10% 30 The Minnesota Rural Waters Association, the Metropolitan Council and the Department of Natural Resources recommend that all water uses be metered. Metering can help identify high use locations and times, along with leaks within buildings that have multiple meters. It is difficult to quantify specific unmetered water use such as that associated with firefighting and system flushing or system leaks. Typically, water suppliers subtract metered water use from total water pumped to calculate unaccounted or non-revenue water loss. Is your five-year average (2010-2015) unaccounted Water Use in Table 2 higher than 10%? Yes ☐ No ☒ What is your leak detection monitoring schedule? (e.g. monitor 1/3rd of the city lines per year) The City conducts leak detection coincident with street reconstruction projects, averaging 37,500 feet per year, or as needed to make water main repairs. Water Audits - are intended to identify, quantify and verify water and revenue losses. The volume of unaccounted-for water should be evaluated each billing cycle. The American Water Works Association (AWWA) recommends that ten percent or less of pumped water is unaccounted-for water. Water audit procedures are available from the AWWA and MN Rural Water Association www.mrwa.com . Drinking Water Revolving Loan Funds are available for purchase of new meters when new plants are built. What is the date of your most recent water audit? January 2015 Frequency of water audits: ☒ yearly ☐ other (specify frequency) ________ Leak detection and survey: ☐ every year ☐ every other year ☒ periodic as needed Year last leak detection survey completed: _________ If Table 2 shows annual water losses over 10% or an increasing trend over time, describe what actions will be taken to reach the <10% loss objective and within what timeframe Unaccounted for water approaching 10 percent is indicative of an unusual or extraordinary water event in the City associated with development contractors or specific water quality needs of specific industrial customers. The City has strived to maintain unaccounted for water at less than the 10 percent threshold for the last 16 years. Metering -AWWA recommends that every water supplier install meters to account for all water taken into its system, along with all water distributed from its system at each customer’s point of service. An effective metering program relies upon periodic performance testing, repair, maintenance or replacement of all meters. AWWA also recommends that water suppliers conduct regular water audits to ensure accountability. Some cities install separate meters for interior and exterior water use, but some research suggests that this may not result in water conservation. 31 Complete Table 23 by adding the requested information regarding the number, types, testing and maintenance of customer meters. Table 23.

Is your average 2010-2015 residential per capita water demand in Table 2 more than 75? Yes ☒ No ☐ What was your 2010 – 2015 five-year average residential per capita water demand? 86.86 g/person/day Describe the water use trend over that timeframe: The water use trend has varied with the weather. Over the past 10 years residential per capita demand has trended downward. 32 Complete Table 25 by checking which strategies you will use to continue reducing residential per capita demand and project a likely timeframe for completing each checked strategy (Select all that apply and add rows for additional strategies): Table 25. Strategies and timeframe to reduce residential per capita demand Strategy to reduce residential per capita demand Timeframe for completing work ☐ Revise city ordinances/codes to encourage or require water efficient landscaping. ☐ Revise city ordinance/codes to permit water reuse options, especially for non-potable purposes like irrigation, groundwater recharge, and industrial use. Check with plumbing authority to see if internal buildings reuse is permitted ☐ Revise ordinances to limit irrigation. Describe the restricted irrigation plan: ☐ Revise outdoor irrigation installations codes to require high efficiency systems (e.g. those with soil moisture sensors or programmable watering areas) in new installations or system replacements. ☒ Make water system infrastructure improvements Ongoing ☐ Offer free or reduced cost water use audits for residential customers. ☒ Implement a notification system to inform customers when water availability conditions change. Existing through online and broadcast media. ☒ Provide rebates or incentives for installing water efficient appliances and/or fixtures indoors (e.g., low flow toilets, high efficiency dish washers and washing machines, showerhead and faucet aerators, water softeners, etc.) 2018 ☒ Provide rebates or incentives to reduce outdoor water use (e.g., turf replacement/reduction, rain gardens, rain barrels, smart irrigation, outdoor water use meters, etc.) 2020 ☐ Identify supplemental Water Resources ☒ Conduct audience-appropriate water conservation education and outreach. Annually ☐ Describe other plans Objective 3: Achieve at least a 1.5% per year water reduction for Institutional, Industrial, Commercial, and Agricultural GPCD over the next 10 years or a 15% reduction in ten years. Complete Table 26 by checking which strategies you will used to continue reducing non-residential customer use demand and project a likely timeframe for completing each checked strategy (add rows for additional strategies). Where possible, substitute recycled water used in one process for reuse in another. (For example, spent rinse water can often be reused in a cooling tower.) Keep in mind the true cost of water is the amount on the water bill PLUS the expenses to heat, cool, treat, pump, and dispose of/discharge the water. Don’t just calculate the initial investment. Many conservation retrofits that appear to be prohibitively expensive are actually very cost-effective when amortized over the life of the equipment. Often reducing water use also saves electrical and other utility costs. Note: as of 2015, water reuse, and is not 33 allowed by the state plumbing code, M.R. 4715 (a variance is needed). However several state agencies are addressing this issue. Table 26. Strategies and timeframe to reduce institutional, commercial, industrial, and agricultural and non-revenue use demand Strategy to reduce total business, industry, agricultural demand Timeframe for completing work ☐ Conduct a facility water use audit for both indoor and outdoor use, including system components ☒ Install enhanced meters capable of automated readings to detect spikes in consumption Ongoing. Meters replaced at least every 15 years to 20 years to ensure water use data is accurately captured. ☐ Compare facility water use to related industry benchmarks, if available (e.g., meat processing, dairy, fruit and vegetable, beverage, textiles, paper/pulp, metals, technology, petroleum refining etc.) ☐ Install water conservation fixtures and appliances or change processes to conserve water ☒ Repair leaking system components (e.g., pipes, valves) Ongoing. Repairs made as leaks discovered. Hydrant and valve bolts are replaced during annual street reconstruction projects. ☒ Investigate the reuse of reclaimed water (e.g., stormwater, wastewater effluent, process wastewater, etc.) The City has already started program to reuse stormwater for irrigation of two of its athletic complexes. ☐ Reduce outdoor water use (e.g., turf replacement/reduction, rain gardens, rain barrels, smart irrigation, outdoor water use meters, etc.) ☐ Train employees how to conserve water ☐ Implement a notification system to inform non-residential customers when water availability conditions change. ☐ Rainwater catchment systems intended to supply uses such as water closets, urinals, trap primers for floor drains and floor sinks, industrial processes, water features, vehicle washing facilities, cooling tower makeup, and similar uses shall be approved by the commissioner. Proposed plumbing code 4714.1702.1 http://www.dli.mn.gov/PDF/docket/4714rule.pdf ☐ Describe other plans: Objective 4: Achieve a Decreasing Trend in Total Per Capita Demand Include as Appendix 8 one graph showing total per capita water demand for each customer category (i.e., residential, institutional, commercial, industrial) from 2005-2015 and add the calculated/estimated linear trend for the next 10 years. Describe the trend for each customer category; explain the reason(s) for the trends, and where trends are increasing. The trend for residential per capita demand has decreased over the last ten years. With regard to future trends, the City has no way to calculate the impacts of continuing growth and weather factors on residential per capita demand. 34 No trends are available in other customer categories because there is no way to track the population in those customer categories. Objective 5: Reduce Peak Day Demand so that the Ratio of Average Maximum day to the Average Day is less than 2.6 Is the ratio of average 2005-2015 maximum day demand to average 2005-2015 average day demand reported in Table 2 more than 2.6? Yes ☒ No ☐ Calculate the average (2005 – 2015) of the ratio of maximum day demand to average day demand: 2.68 The position of the DNR has been that a peak day/average day ratio that is above 2.6 for in summer indicates that the water being used for irrigation by the residents in a community is too large and that efforts should be made to reduce the peak day use by the community. It should be noted that by reducing the peak day use, communities can also reduce the amount of infrastructure that is required to meet the peak day use. This infrastructure includes new wells, new water towers which can be costly items. Objective 6: Implement a Conservation Water Rate Structure and/or a Uniform Rate Structure with a Water Conservation Program Water Conservation Program Municipal water suppliers serving over 1,000 people are required to adopt demand reduction measures that include a conservation rate structure, or a uniform rate structure with a conservation program that achieves demand reduction. These measures must achieve demand reduction in ways that reduce water demand, water losses, peak water demands, and nonessential water uses. These measures must be approved before a community may request well construction approval from the Department of Health or before requesting an increase in water appropriations permit volume (Minnesota Statutes, section 103G.291, subd. 3 and 4). Rates should be adjusted on a regular basis to ensure that revenue of the system is adequate under reduced demand scenarios. If a municipal water supplier intends to use a Uniform Rate Structure, a community-wide Water Conservation Program that will achieve demand reduction must be provided. Current Water Rates Include a copy of the actual rate structure in Appendix 9 or list current water rates including base/service fees and volume charges below. Volume included in base rate or service charge: __0__ gallons or ____ cubic feet ___ other Frequency of billing: ☐ Monthly ☐ Bimonthly ☒ Quarterly ☐ Other: _________________ Water Rate Evaluation Frequency: ☒ every year ☐ every ___ years ☐ no schedule Date of last rate change: February 1, 2016 35 Table 27. Rate structures for each customer category (Select all that apply and add additional rows as needed) Customer Category Conservation Billing Strategies in Use * Conservation Neutral Billing Strategies in Use ** Non-Conserving Billing Strategies in Use *** Residential ☐ Monthly billing ☒ Increasing block rates (volume tiered rates) ☐ Seasonal rates ☐ Time of use rates ☐ Water bills reported in gallons ☐ Individualized goal rates ☐ Excess use rates ☐ Drought surcharge ☐ Use water bill to provide comparisons ☐ Service charge not based on water volume ☐ Other (describe) ☐ Uniform ☒ Odd/even day watering ☐ Service charge based on water volume ☐ Declining block ☐ Flat ☐ Other (describe) Commercial/ Industrial/ Institutional ☐ Monthly billing ☒ Increasing block rates (volume tiered rates) ☐ Seasonal rates ☐ Time of use rates ☐ Water bills reported in gallons ☐ Individualized goal rates ☐ Excess use rates ☐ Drought surcharge ☐ Use water bill to provide comparisons ☐ Service charge not based on water volume ☐ Other (describe) ☐ Uniform ☐ Service charge based on water volume ☐ Declining block ☐ Flat ☐ Other (describe) ☐ Other * Rate Structures components that may promote water conservation: • Monthly billing: is encouraged to help people see their water usage so they can consider changing behavior. • Increasing block rates (also known as a tiered residential rate structure): Typically, these have at least three tiers: should have at least three tiers. o The first tier is for the winter average water use. o The second tier is the year-round average use, which is lower than typical summer use. This rate should be set to cover the full cost of service. o The third tier should be above the average annual use and should be priced high enough to encourage conservation, as should any higher tiers. For this to be effective, the difference in block rates should be significant. • Seasonal rate: higher rates in summer to reduce peak demands • Time of Use rates: lower rates for off peak water use 36 • Bill water use in gallons: this allows customers to compare their use to average rates • Individualized goal rates: typically used for industry, business or other large water users to promote water conservation if they keep within agreed upon goals. Excess Use rates: if water use goes above an agreed upon amount this higher rate is charged • Drought surcharge: an extra fee is charged for guaranteed water use during drought • Use water bill to provide comparisons: simple graphics comparing individual use over time or compare individual use to others. • Service charge or base fee that does not include a water volume – a base charge or fee to cover universal city expenses that are not customer dependent and/or to provide minimal water at a lower rate (e.g., an amount less than the average residential per capita demand for the water supplier for the last 5 years) • Emergency rates -A community may have a separate conservation rate that only goes into effect when the community or governor declares a drought emergency. These higher rates can help to protect the city budgets during times of significantly less water usage. **Conservation Neutral** • Uniform rate: rate per unit used is the same regardless of the volume used • Odd/even day watering –This approach reduces peak demand on a daily basis for system operation, but it does not reduce overall water use. *** Non-Conserving *** • Service charge or base fee with water volume: an amount of water larger than the average residential per capita demand for the water supplier for the last 5 years • Declining block rate: the rate per unit used decreases as water use increases. • Flat rate: one fee regardless of how much water is used (usually unmetered). Provide justification for any conservation neutral or non-conserving rate structures. If intending to adopt a conservation rate structure, include the timeframe to do so: Objective 7: Additional strategies to Reduce Water Use and Support Wellhead Protection Planning Development and redevelopment projects can provide additional water conservation opportunities, such as the actions listed below. If a Uniform Rate Structure is in place, the water supplier must provide a Water Conservation Program that includes at least two of the actions listed below. Check those actions that you intent to implement within the next 10 years. Table 28. Additional strategies to Reduce Water Use & Support Wellhead Protection ☒ Participate in the GreenStep Cities Program, including implementation of at least one of the 20 “Best Practices” for water ☐ Prepare a master plan for smart growth (compact urban growth that avoids sprawl) ☐ Prepare a comprehensive open space plan (areas for parks, green spaces, natural areas) ☐ Adopt a water use restriction ordinance (lawn irrigation, car washing, pools, etc.) ☐ Adopt an outdoor lawn irrigation ordinance ☐ Adopt a private well ordinance (private wells in a city must comply with water restrictions) ☐ Implement a stormwater management program ☐ Adopt non-zoning wetlands ordinance (can further protect wetlands beyond state/federal laws- for vernal pools, buffer areas, restrictions on filling or alterations) 37 ☐ Adopt a water offset program (primarily for new development or expansion) ☐ Implement a water conservation outreach program ☐ Hire a water conservation coordinator (part-time) ☒ Implement a rebate program for water efficient appliances, fixtures, or outdoor water management ☐ Other Objective 8: Tracking Success: How will you track or measure success through the next ten years? Numbers of residents that take advantage of the rebate programs. Monitoring quarterly trends in aggregate and per capita water use. Tip: The process to monitor demand reduction and/or a rate structure includes: a) The DNR Hydrologist will call or visit the community the first 1-3 years after the water supply plan is completed. b) They will discuss what activities the community is doing to conserve water and if they feel their actions are successful. The Water Supply Plan, Part 3 tables and responses will guide the discussion. For example, they will discuss efforts to reduce unaccounted for water loss if that is a problem, or go through Tables 33, 34 and 35 to discuss new initiatives. c) The city representative and the hydrologist will discuss total per capita water use, residential per capita water use, and business/industry use. They will note trends. d) They will also discuss options for improvement and/or collect case studies of success stories to share with other communities. One option may be to change the rate structure, but there are many other paths to successful water conservation. e) If appropriate, they will cooperatively develop a simple work plan for the next few years, targeting a couple areas where the city might focus efforts. A. Regulation Complete Table 29 by selecting which regulations are used to reduce demand and improve water efficiencies. Add additional rows as needed. Copies of adopted regulations or proposed restrictions or should be included in Appendix 10 (a list with hyperlinks is acceptable). Table 29. Regulations for short-term reductions in demand and long-term improvements in water efficiencies Regulations Utilized When is it applied (in effect)? ☒ Rainfall sensors required on landscape irrigation systems ☒ Ongoing ☐ Seasonal ☐ Only during declared Emergencies ☒ Water efficient plumbing fixtures required ☒ New development ☒ Replacement ☐ Rebate Programs ☒ Critical/Emergency Water Deficiency ordinance ☒ Only during declared Emergencies ☒ Watering restriction requirements (time of day, allowable days, etc.) ☒ Odd/even ☐ 2 days/week ☐ Only during declared Emergencies 38 Regulations Utilized When is it applied (in effect)? ☐ Water waste prohibited (for example, having a fine for irrigators spraying on the street) ☐ Ongoing ☐ Seasonal ☐ Only during declared Emergencies ☐ Limitations on turf areas (requiring lots to have 10% - 25% of the space in natural areas) ☐ New development ☐ Shoreland/zoning ☐ Other ☒ Soil preparation requirement s (after construction, requiring topsoil to be applied to promote good root growth) ☒ New Development ☒ Construction Projects ☐ Other ☒ Tree ratios (requiring a certain number of trees per square foot of lawn) ☒ New development ☐ Shoreland/zoning ☐ Other ☒ Permit to fill swimming pool and/or requiring pools to be covered (to prevent evaporation) ☒ Ongoing ☐ Seasonal ☐ Only during declared Emergencies ☐ Ordinances that permit stormwater irrigation, reuse of water, or other alternative water use (Note: be sure to check current plumbing codes for updates) ☐ Describe B. Retrofitting Programs Education and incentive programs aimed at replacing inefficient plumbing fixtures and appliances can help reduce per capita water use, as well as energy costs. It is recommended that municipal water suppliers develop a long-term plan to retrofit public buildings with water efficient plumbing fixtures and appliances. Some water suppliers have developed partnerships with organizations having similar conservation goals, such as electric or gas suppliers, to develop cooperative rebate and retrofit programs. A study by the AWWA Research Foundation (Residential End Uses of Water, 1999) found that the average indoor water use for a non-conserving home is 69.3 gallons per capita per day (gpcd). The average indoor water use in a conserving home is 45.2 gpcd and most of the decrease in water use is related to water efficient plumbing fixtures and appliances that can reduce water, sewer and energy costs. In Minnesota, certain electric and gas providers are required (Minnesota Statute 216B.241) to fund programs that will conserve energy resources and some utilities have distributed water efficient showerheads to customers to help reduce energy demands required to supply hot water. Retrofitting Programs Complete Table 30 by checking which water uses are targeted, the outreach methods used, the measures used to identify success, and any participating partners. Table 30.

C. Education and Information Programs Customer education should take place in three different circumstances. First, customers should be provided information on how to conserve water and improve water use efficiencies. Second, information should be provided at appropriate times to address peak demands. Third, emergency notices and educational materials about how to reduce water use should be available for quick distribution during an emergency. Proposed Education Programs Complete Table 31 by selecting which methods are used to provide water conservation and information, including the frequency of program components.

ITEMS FOR METROPOLITAN AREA COMMUNITIES Minnesota Statute 473.859 requires WSPs to be completed for all local units of government in the seven-county Metropolitan Area as part of the local comprehensive planning process. Much of the information in Parts 1-3 addresses water demand for the next 10 years. However, additional information is needed to address water demand through 2040, which will make the WSP consistent with the Metropolitan Land Use Planning Act, upon which the local comprehensive plans are based. This Part 4 provides guidance to complete the WSP in a way that addresses plans for water supply through 2040. A. Water Demand Projections through 2040 Complete Table 7 in Part 1D by filling in information about long-term water demand projections through 2040. Total Community Population projections should be consistent with the community’s system statement, which can be found on the Metropolitan Council’s website and which was sent to the community in September 2015. Projected Average Day, Maximum Day, and Annual Water Demands may either be calculated using the method outlined in Appendix 2 of the 2015 Master Water Supply Plan or by a method developed by the individual water supplier. B. Potential Water Supply Issues Complete Table 10 in Part 1E by providing information about the potential water supply issues in your community, including those that might occur due to 2040 projected water use. The Master Water Supply Plan provides information about potential issues for your community in Appendix 1 (Water Supply Profiles). This resource may be useful in completing Table 10. You may document results of local work done to evaluate impact of planned uses by attaching a feasibility assessment or providing a citation and link to where the plan is available electronically. C. Proposed Alternative Approaches to Meet Extended Water Demand Projections Complete Table 12 in Part 1F with information about potential water supply infrastructure impacts (such as replacements, expansions or additions to wells/intakes, water storage and treatment capacity, distribution systems, and emergency interconnections) of extended plans for development and redevelopment, in 10-year increments through 2040. It may be useful to refer to information in the community’s local Land Use Plan, if available. Complete Table 14 in Part 1F by checking each approach your community is considering to meet future demand. For each approach your community is considering, provide information about the amount of 44 future water demand to be met using that approach, the timeframe to implement the approach, potential partners, and current understanding of the key benefits and challenges of the approach. As challenges are being discussed, consider the need for: evaluation of geologic conditions (mapping, aquifer tests, modeling), identification of areas where domestic wells could be impacted, measurement and analysis of water levels & pumping rates, triggers & associated actions to protect water levels, etc. D. Value-Added Water Supply Planning Efforts (Optional) The following information is not required to be completed as part of the local water supply plan, but completing this can help strengthen source water protection throughout the region and help Metropolitan Council and partners in the region to better support local efforts. Source Water Protection Strategies Does a Drinking Water Supply Management Area for a neighboring public water supplier overlap your community? Yes ☒ No ☐ If you answered no, skip this section. If you answered yes, please complete Table 32 with information about new water demand or land use planning-related local controls that are being considered to provide additional protection in this area. Table 32. Local controls and schedule to protect Drinking Water Supply Management Areas Local Control Schedule to Implement Potential Partners ☐ None at this time ☒ Comprehensive planning that guides development in vulnerable drinking water supply management areas 2019 Apple Valley and Rosemount ☐ Zoning overlay ☐ Other: Technical assistance From your community’s perspective, what are the most important topics for the Metropolitan Council to address, guided by the region’s Metropolitan Area Water Supply Advisory Committee and Technical Advisory Committee, as part of its ongoing water supply planning role? ☐ Coordination of state, regional and local water supply planning roles ☒ Regional water use goals ☒ Water use reporting standards ☐ Regional and sub-regional partnership opportunities ☐ Identifying and prioritizing data gaps and input for regional and sub-regional analyses ☐ Others: ___________________________________________________________________ 45 GLOSSARY Agricultural/Irrigation Water Use - Water used for crop and non-crop irrigation, livestock watering, chemigation, golf course irrigation, landscape and athletic field irrigation. Average Daily Demand - The total water pumped during the year divided by 365 days. Calcareous Fen - Calcareous fens are rare and distinctive wetlands dependent on a constant supply of cold groundwater. Because they are dependent on groundwater and are one of the rarest natural communities in the United States, they are a protected resource in MN. Approximately 200 have been located in Minnesota. They may not be filled, drained or otherwise degraded. Commercial/Institutional Water Use - Water used by motels, hotels, restaurants, office buildings, commercial facilities and institutions (both civilian and military). Consider maintaining separate institutional water use records for emergency planning and allocation purposes. Water used by multi- family dwellings, apartment buildings, senior housing complexes, and mobile home parks should be reported as Residential Water Use. Commercial/Institutional/Industrial (C/I/I) Water Sold - The sum of water delivered for commercial/institutional or industrial purposes. Conservation Rate Structure - A rate structure that encourages conservation and may include increasing block rates, seasonal rates, time of use rates, individualized goal rates, or excess use rates. If a conservation rate is applied to multifamily dwellings, the rate structure must consider each residential unit as an individual user. A community may have a separate conservation rate that only goes into effect when the community or governor declares a drought emergency. These higher rates can help to protect the city budgets during times of significantly less water usage. Date of Maximum Daily Demand - The date of the maximum (highest) water demand. Typically this is a day in July or August. Declining Rate Structure - Under a declining block rate structure, a consumer pays less per additional unit of water as usage increases. This rate structure does not promote water conservation. Distribution System - Water distribution systems consist of an interconnected series of pipes, valves, storage facilities (water tanks, water towers, reservoirs), water purification facilities, pumping stations, flushing hydrants, and components that convey drinking water and meeting fire protection needs for cities, homes, schools, hospitals, businesses, industries and other facilities. Flat Rate Structure - Flat fee rates do not vary by customer characteristics or water usage. This rate structure does not promote water conservation. Industrial Water Use - Water used for thermonuclear power (electric utility generation) and other industrial use such as steel, chemical and allied products, paper and allied products, mining, and petroleum refining. 46 Low Flow Fixtures/Appliances - Plumbing fixtures and appliances that significantly reduce the amount of water released per use are labeled “low flow”. These fixtures and appliances use just enough water to be effective, saving excess, clean drinking water that usually goes down the drain. Maximum Daily Demand - The maximum (highest) amount of water used in one day. Metered Residential Connections - The number of residential connections to the water system that have meters. For multifamily dwellings, report each residential unit as an individual user. Percent Unmetered/Unaccounted For - Unaccounted for water use is the volume of water withdrawn from all sources minus the volume of water delivered. This value represents water “lost” by miscalculated water use due to inaccurate meters, water lost through leaks, or water that is used but unmetered or otherwise undocumented. Water used for public services such as hydrant flushing, ice skating rinks, and public swimming pools should be reported under the category “Water Supplier Services”. Population Served - The number of people who are served by the community’s public water supply system. This includes the number of people in the community who are connected to the public water supply system, as well as people in neighboring communities who use water supplied by the community’s public water supply system. It should not include residents in the community who have private wells or get their water from neighboring water supply. Residential Connections - The total number of residential connections to the water system. For multifamily dwellings, report each residential unit as an individual user. Residential Per Capita Demand - The total residential water delivered during the year divided by the population served divided by 365 days. Residential Water Use - Water used for normal household purposes such as drinking, food preparation, bathing, washing clothes and dishes, flushing toilets, and watering lawns and gardens. Should include all water delivered to single family private residences, multi-family dwellings, apartment buildings, senior housing complexes, mobile home parks, etc. Smart Meter - Smart meters can be used by municipalities or by individual homeowners. Smart metering generally indicates the presence of one or more of the following: • Smart irrigation water meters are controllers that look at factors such as weather, soil, slope, etc. and adjust watering time up or down based on data. Smart controllers in a typical summer will reduce water use by 30%-50%. Just changing the spray nozzle to new efficient models can reduce water use by 40%. • Smart Meters on customer premises that measure consumption during specific time periods and communicate it to the utility, often on a daily basis. • A communication channel that permits the utility, at a minimum, to obtain meter reads on demand, to ascertain whether water has recently been flowing through the meter and onto the 47 premises, and to issue commands to the meter to perform specific tasks such as disconnecting or restricting water flow. Total Connections - The number of connections to the public water supply system. Total Per Capita Demand - The total amount of water withdrawn from all water supply sources during the year divided by the population served divided by 365 days. Total Water Pumped - The cumulative amount of water withdrawn from all water supply sources during the year. Total Water Delivered - The sum of residential, commercial, industrial, institutional, water supplier services, wholesale and other water delivered. Ultimate (Full Build-Out) - Time period representing the community’s estimated total amount and location of potential development, or when the community is fully built out at the final planned density. Unaccounted (Non-revenue) Loss - See definitions for “percent unmetered/unaccounted for loss”. Uniform Rate Structure - A uniform rate structure charges the same price-per-unit for water usage beyond the fixed customer charge, which covers some fixed costs. The rate sends a price signal to the customer because the water bill will vary by usage. Uniform rates by class charge the same price-per- unit for all customers within a customer class (e.g. residential or non-residential). This price structure is generally considered less effective in encouraging water conservation. Water Supplier Services - Water used for public services such as hydrant flushing, ice skating rinks, public swimming pools, city park irrigation, back-flushing at water treatment facilities, and/or other uses. Water Used for Nonessential Purposes - Water used for lawn irrigation, golf course and park irrigation, car washes, ornamental fountains, and other non-essential uses. Wholesale Deliveries - The amount of water delivered in bulk to other public water suppliers.

Data sent previously regarding the amended 2008 water appropriation permit no longer exists other than in the well logs provided. Maintenance summaries provided separately. See separate upload titled Appendix 1 – Well Maintenance Summaries 51 Appendix 2: Water Level Monitoring Plan 52 Water Level Monitoring Plan Purpose. Provide guidance and outline procedures for monitoring the water levels in each of Lakeville’s wells. General. All water supply wells are checked on a weekly basis to ensure proper operation, exercise the security system, and verify control readings. Procedures. All water supply wells will be manually measured at least once per month. Measurements can be taken when the well is operating. Staff measuring the well will use a water level meter with a laser etched tape accurate to 1/10th of a foot. Water depth readings will be taken directly from the tape and entered into the log at each well. Water level data for the wells will be maintained by the Utilities Division for the life of the well. 53 Appendix 4: Capital Improvement Plan 54 Project Name: Watermain Trunk System Improvements Project Manager: Chris Petree, Public Works Director Anticipated Start: As development occurs Project Description and Location The Comprehensive Water Plan anticipates the extension of watermain trunk facilities to accommodate anticipated growth.
