Project Details

 

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 under 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 peak demand.

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 outdoor events.
