That such the Water Treatment Plant Feasibility Study, a copy of which is attached hereto and made part hereof, is hereby accepted. • Adopted by the Lino Lakes City Council this 24th day of September, 2007. The motion for the adoption of the foregoing ordinance was duly seconded by Council Member o' Donne 1 nd upon vote being taken thereon, the following voted in favor thereof: Reinert, O'Donnell, Carlson, Stoltz, Bergeson The following voted against same: none Whereupon saidresoiuti_owas declared duly passed and adopted. • • • STAFF ORIGINATOR: CITY COUNCIL MEETING DATE: TOPIC: ACTION REQUIRED: BACKGROUND AGENDA ITEM 6B Jim Studenski, City Engineer September 24, 2007 Resolution No. 07 -150, Accepting Feasibility Report, Water Treatment Plant 3/5 Vote Lino Lakes water supply is provided by the Jordan sandstone aquifer. This source is considered abundant and meets all health requirements. The City does not treat its water for iron and/or manganese removal, softening, or any other conventional treatment processes. The City does provide chemical additions including disinfection and fluoridation at the wellheads. Blending of raw well water with treated water on peak days has been evaluated to reduce treatment plant size. Blending is accomplished on peak days by sending 75 to 80 percent of the raw water supply through the treatment plant and using a bypass line to allow 20 to 25 percent of the raw water to go directly to the water storage for blending. The proposed water treatment plant is an ideal candidate for blending because the raw water supplied to the treatment plant from the wells does not carry contaminants which cause health related issues. During recent years several metro communities have begun to use blending to reduce water treatment plant capacity. By using the blending of raw well water with treated water, the City can be served by a single treatment plant. The treatment feasibility study utilizes two types of treatment technology and proposes two different plant layouts, based on the space needs that each technology requires. The acreage needed at the two proposed site locations was determined based on those plant layouts. At this time health requirements and resident complaints do not warrant treatment. However, due to the complexities of a water treatment facility and efficient integration of a facility into the City's system of pipes, wells and storage, advanced planning is necessary. The study addresses water quality, future water demands, site selection, plant floor plan options, future infrastructure needs, and financing / funding alternatives. Attached is the Water Treatment Plant Feasibility Study, dated September 17, 2007. • Capital Improvement Program: The water treatment complex cost (including engineering, administrative, and financing costs) are estimated at $12,050,000, this cost includes $3,000,000 for construction of the ground storage tank, booster station and well no. 7 and $9,050,000 for the construction of the treatment plant. The additional wells, well houses and raw watermain are estimated to cost $4,825,000. The cost of the distribution system improvements is estimated to be $2,895,000. As the water treatment plant would provide substantial benefit for the existing water customers, water rate increases could be utilized to fund a portion of the project. The remainder of the costs could be funded by a water availability charge for new connections. The capital improvement program phases in the wells and watermains as needed for population growth. It also shows the centralized storage reservoir and booster station being built in the 2010 to 2012 time period when more storage is necessary. Using the capital improvement program and system layout, the treatment plant can be added in the future and is shown in 2017. The detailed capital improvement program can be found on page 26 of the attached water treatment plant feasibility study. RECOMMENDATION Staff recommends approving Resolution No. 07 -150, accepting the Water Treatment Plant Feasibility Study.
