'~+J~ Elk River Municip al Utilitie s 13069 Orono Parkway Elk River, MN 55330 August 8, 2006 To: Elk River Municipal Utilities Commission Jerry Takle John Dietz Jim Tralle From: Bryan Adams Subject: Proposed Water Main Projects '~ '"~ phone: 763.441.2020 Fax: 763.491.8099 This 2006 water budget contains the following two water main projects: a) Loop dead end water main at Guardian Angels for $12,000 b) Loop water main at 175`x' Av to improve Johnson St. water tower for $75,000 The $75,000 looping water main projects (item b above) was replaced with the Hyland Av. Water main project due to rebuilding Hyland Av. Guardian Angels is proposing an addition to their facilities which is the cross hatched area on the attached drawing. They need to extend the water main for fire protection & hydrants (dark blue line) and loop internal water lines (light blue line). We at our cost would extend the water main north (red line) thereby closing the water main loop and provide better fire protection to the Abra/JR Teck/Tires Plus building. The cost to the ERMU is estimated to be in the $55,000 range. This is a good project where both Guardian Angels benefits, the fire department can provide better fire protection and we loop the water system in this area. Due to Guardian Angels construction schedule, staff recommends authorization be given to proceed with this project and complete it in 2006. Also attached is a water main map of S.E. Elk River. Our original plan was to construct a water main from 175`x' Av North and tie it into the Trott Brook Farms South development water main thereby securing two sources of feed/discharge for the Johnson St. water tower. This was not done due to easement issues and Hyland Av project using the funds. Wells 7 & 8 feed treatment plant #7 but we have been experiencing high pressure issues at plant #7 when both wells 7 & 8 run together. This situation will be made worse when we construct proposed well #1 1 which will also feed plant #7. The solution is to construct another 12" water main from plant #7 south to Co Rd 12 (red line). This additional line will dissipate the water quicker, this reducing the pressure. This addition will also reinforce the flow through the 10" proposed main from 175`x' Av to Trott Brook Farms South. These projects we are proposing to do together which is estimated to be 4500' for $270,000. Staff is recommending this project start engineering this year for early 2007 construction and be ready by late May 2007 for the summer peak. These water mains will be directional bored in public right way instead of private easements.
