• <br />• <br />STAFF ORIGINATOR: <br />CITY COUNCIL <br />MEETING DATE: <br />TOPIC: <br />ACTION REQUIRED: <br />BACKGROUND <br />AGENDA ITEM 6B <br />Jim Studenski, City Engineer <br />September 24, 2007 <br />Resolution No. 07 -150, Accepting <br />Feasibility Report, Water Treatment Plant <br />3/5 Vote <br />Lino Lakes water supply is provided by the Jordan sandstone aquifer. This source is <br />considered abundant and meets all health requirements. The City does not treat its <br />water for iron and/or manganese removal, softening, or any other conventional <br />treatment processes. The City does provide chemical additions including disinfection <br />and fluoridation at the wellheads. <br />Blending of raw well water with treated water on peak days has been evaluated to <br />reduce treatment plant size. Blending is accomplished on peak days by sending 75 to <br />80 percent of the raw water supply through the treatment plant and using a bypass line <br />to allow 20 to 25 percent of the raw water to go directly to the water storage for <br />blending. The proposed water treatment plant is an ideal candidate for blending <br />because the raw water supplied to the treatment plant from the wells does not carry <br />contaminants which cause health related issues. During recent years several metro <br />communities have begun to use blending to reduce water treatment plant capacity. By <br />using the blending of raw well water with treated water, the City can be served by a <br />single treatment plant. <br />The treatment feasibility study utilizes two types of treatment technology and proposes <br />two different plant layouts, based on the space needs that each technology requires. <br />The acreage needed at the two proposed site locations was determined based on those <br />plant layouts. <br />At this time health requirements and resident complaints do not warrant treatment. <br />However, due to the complexities of a water treatment facility and efficient integration <br />of a facility into the City's system of pipes, wells and storage, advanced planning is <br />necessary. The study addresses water quality, future water demands, site selection, <br />plant floor plan options, future infrastructure needs, and financing / funding <br />alternatives. <br />Attached is the Water Treatment Plant Feasibility Study, dated September 17, 2007. <br />
