Paul Oehme, Dir. of Public Works/City Engineer ~~ ~ October 24, 2005 FROM: DATE: SUBJ: Approve Plans & Specifications; Authorize Advertisement for Bids for Well Nos. 10 & 11 - Project No. 04-08A REQUESTED ACTION Approve plans and specifications and authorize advertisement for bids for Well Nos. 10 & 11, Project No. 04-08A. BACKGROUND On August 22, 2005, Council approved a contract for engineering services for Well Nos. 10 and 11. On July 22,2005, a pump test report was competed for the wells. In May, 2004, in conjunction with the East Water Treatment Plant project, a Lotus Lake Well Siting Study was conducted. This study helped identify the near- and long-term water needs for the City. It also reinforced the need for a new well to help meet the current demands. The proposed well improvements are anticipated to meet the demands of the City until 2010. The new wells will be treated at the east water treatment plant. The electrical controls for the wells were included in the east water treatment plant contract so no new external panels will be required. Also, the raw waterrnains for the two wells were included in the treatment plant contract. The construction contract for Well Nos. 10 & 11 includes drilling and furnishing the pump equipment necessary for wells. Staff would like to have both wells operational by the time the east water treatment plant is operational so the plant does not have to be reset in the future due to changes in the chemistry of the raw water. Also, by having more water treated at the treatment plant, less untreated water will be distributed into the system for an average day demand event. The consultant has completed the plans and specifications for the two wells. A copy of the project documents is available in the Engineering Department. Funding for the project was identified in the 2004 CIP - W002&3, and was included in the 2005 water rate study. Funding of the project is planned for by using revenue bonds. c: Marcus Thomas, Bolton & Menk, Inc. g:\eng\public\04-08a well 10& 11 \bkgd 102405 apv ps auth add. doc The City 01 Chanhassen .
