City Well No. 11 Equipping and Collection
Project Number 09-058-001
The City of Mesa has awarded this project to
City Wide Contracting
Pump and chlorination system start up complete.
Construction on this project began in March 2012 and is
expected to be completed by April 2013.
The City of Mesa maintains and operates numerous
groundwater wells throughout the City to provide drinking water
for Mesa citizens. The well at this site was drilled un
a separate contract completed in the fall of 2009. This project
will install the necessary pump, piping, electrical,
chlorination equipment and other site improvements to make this
well operational. Additionally, this project completes a
pipeline that connects City Well No. 11 to the Pasadena
Reservoir. The pipeline will allow for the conveyance of
additional groundwater to the reservoir to meet storage
requirements when treated surface water is unavailable. This
well also has the ability to pump water directly into the City's
water distribution system during emergencies or during times of
The Pasadena Reservoir is one of three reservoirs that
provide storage for water distribution within the City Pressure
Zone. The major source of water for the reservoir is the
Val Vista Water Treatment Plant (VVWTP). The reservoir is
typically filled at night or during periods of low water demand.
As demand increases during the day, water from the reservoir is
pumped into the water distribution system. During times
when the VVWTP is out of service or water demand is high, the
Pasadena Reservoir may be filled by using various city
groundwater wells (City Wells 8, 9, and 12). These wells have
the ability to maintain reservoir levels, but if one of these
wells were to malfunction, the City may not have the ability to
maintain reservoir water storage.
This new well is located adjacent to
the Rendezvous Center. The Rendezvous Center is used for
staff office space, meetings, weddings, and other conferences.
This project will install a 10-foot high perimeter
screen/security wall around the well site and an acoustical
enclosure around the well to minimize the noise generated by and
the visibility of the well. Landscaping will be added to
the area and a plaza will be constructed as a place to hold
The recommended total award amount
for this project is $2,282,504.40 based on the lowest bid of
$2,075,004 plus an additional $207,500.40 (10% allowance for
change orders). Funding is available in the FY 11/12
Water Bond Capital Program.
