HomeMy WebLinkAboutItem 06.dDate: 25 March 2013 iN APPROVAL OF AN AGREEMENT WITH BLACK & VEATCH TO CONDUCT A FULL -SCALE FILTER PILOT STUDY AT THE WATER TREATMENT FACILITY Proposed Action Staff recommends adoption of the following motion: Move to approve an agreement with Black & Veatch to conduct a full -scale filter pilot study at the Water Treatment Facilit�r. Passage of this motion will result in an assessment of the water filter performance at a higher loading rate. Overview In May 2012, City Council approved an update to the Water Treatment Facility (WTF) expansion study. The purpose of which is to guide the City's capital planning for expansion of the facility to meet expected population increases. Concurrent with that expansion have been discussions of maximizing the capacity and performance of the existing facility. A full -scale filter study will assess the ability of the existing filters to operate at a higher loading rate; the rate at which water passes through the filter media. An increase in the loading rate of the filters enables the City to review the results of the expansion study and mesh the study's alternatives with the City's capital improvement planning cycle. Currently the filters operate at a maximum loading rate of 3 gallons per minute (GPM) per square foot of filter area to achieve the WTF's maximum capacity of 20 million gallons per day (MGD). Increasing the loading to 4 GPM per square foot increases the WTF's maximum capacity to 26.5 MGD which will help the facility meet short term population demands. A full -scale filter pilot study is a valuable tool in evaluating the facility's ability to handle a higher loading rate and the resulting additional production capacity. It also contributes to the decisions that will be made regarding future expansion of the facility and elements of the water distribution system that are necessary as Lakeville's population grows. Primary Issues to Consider • Is filter pilot study necessary? Yes. The data provided by the study may allow the City to meet peak water demands without adding infrastructure as it plans for the future expansion of the WTF.

City of Lakeville (Client) Black & Veatch Corporation (Engineer) By: Title: Date: By: Title: Date: Page 2 of 6 CITY OF LAKEVILLE ATTACHMENT A — SCOPE OF SERVICES The purpose of the full -scale filter pilot study is to assess the performance of the filters operating at a higher loading rate. The filtration rate is currently 3 gpm per square foot. Based on preliminary discussions, the Minnesota Department of Health (MDH) will allow a filter loading rate up to 4 gpm per square foot if the Primary Drinking Water Standards are met. Increasing the filter loading rate from 3 gpm per square foot to 4 gpm per square foot would increase the plant capacity from 20 mgd to 26.5 mgd with all filters in service. The general description of the services to be provided for the Water Treatment Facility Full - Scale Filter Pilot Study is as follows: Develop Pilot Testing Protocol. Develop the full -scale filter pilot testing protocol. The protocol document will provide a systematic approach for implementing the pilot testing including the incremental increases in the filter loading rate; the duration of time between the incremental increases in the filter loading rate; the operational data to be monitored and recorded (initial filter head loss, the rate of filter head loss and the unit filter run volume); and the water quality parameters to be monitored and recorded (raw water iron, manganese & turbidity and filtered water turbidity, iron and manganese). The protocol document will also include tables for recording operations and water quality data. Submit a draft copy of the protocol document to the City and the MDH for review. 2. Protocol Review Meeting. Conduct a meeting with City staff and representatives from the MDH to review the pilot testing protocol. Revise the pilot testing protocol based on the comments received and submit final copies of the document. Review Water Treatment Facility Historic Operating Records Review the plant operating records to establish a baseline for the filter performance. The operating records will include the plant influent water quality, plant flow rates, filter head loss after backwashing, rate of filter head loss, unit filter run volume, filter backwash protocol, and filtered water quality (turbidity, iron and manganese). 4. Filter Hydraulic Anal ysis. Perform hydraulic calculations to determine the available (terminal) filter operating head at incremental filter loading rates. The hydraulic analysis will determine limitations on the hydraulic capacity of the filters. 5. PLC Programming Participate in discussions with Automatic Systems so they can program modifications to the programmable logic controller (PLC) and the supervisory control and data acquisition (SCADA) system. The reprogramming will enable the filtration rate of a selected filter to be manually adjusted to a set -point flow rate. The City will retain the services of Automatic Systems. 6. Water Quality Testing Participate in discussions with the City so that a laboratory can perform plant influent and filter effluent water quality testing including total iron, dissolved Page 3 of 6 CITY OF LAKEVILLE ATTACHMENT A — SCOPE OF SERVICES iron, total manganese and dissolved manganese. The City will either perform the laboratory testing or will utilize an outside laboratory. 7. Review of Weekly Facility Operating Records and Water Quality Reports. Obtain and review plant operating records and water quality reports to assess the performance of the filters. A review and assessment of the filter performance will be conducted prior to each planned incremental increase in the filter loading rate. A four week pilot test is anticipated. 8. Filter Pilot Testing Report Prepare a brief letter report, which will provide a summary of the pilot testing results, conclusions and recommendations. Submit a draft copy of the report to the City and the MDH for review. Update the report to incorporate comments received. The final report will be included as an appendix to the Water Treatment Facility Expansion Study 9. Water Treatment FacilityUp r� Identify water treatment facility upgrades required to accommodate an increase in plant capacity resulting from higher filter loading rates. Equipment or devices to be considered include the chemical metering pumps (potassium permanganate, fluoride and orthophosphate); the chlorine feed system including the feeders and educators; the plant influent magnetic flow meter transmitter; washwater recovery pumping units; and the packaged gravity plate settler. 10. Update the Water Treatment Facility Expansion Study Update the Expansion Study to address the results of the full -scale filter pilot study. In particular, modify the recommendations for expansion based upon the operation of the filters at a higher loading rate. In addition, make the following modifications to the Expansion Study: a. Revise population figures to show population from 2000 - 2040, remove 1999 population projections, and remove 3% growth line. b. Add a discussion regarding the MCES plan to revise population projections in 2013. c. Revise Table 6 -2 to include predicted flows with more conservative growth proj ections. d. Revise Figure 6 -1 to show predictions to 2040. Modify figure to show a band of water demands (high = 2% growth, low = I% growth). e. Identify situations that could jeopardize treatment capacity during maximum flow periods, and expand the description of alternatives for increasing treatment capacity. f. Reassess treated water pumping capacity needs for the increased flow. the alternatives would produce, and update tables as required. g. Adjust and revise the facility improvements table, and adapt conclusions and recommendations as required. Page 4 of 6 CITY OF LAKEVILLE ATTACHMENT A — SCOPE OF SERVICES 11.
