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.

Well #10
Description I
Construction of a municipal water supply well. Well siting and design to be done in 2005 with construction in 2006. The well is anticipated to be incorporated into
the water treatment plant site design.
Total Project Cost $636,000
I
I
I
Justification I
Needed to proVide for increased demand in the system due to city growth. Identified in both the 1998 Comprehensive Water Supply and Distribution Plan and the I
2003 Master Water Study. This well would draw from the Jordan aquifer and the water would be treated by the new treatment plant.
