PUMP STATION AND ODOR CONTROL FACILITY

CITY OF ATWATER – ATWATER, CA


ABOUT

In conjunction with Fremming, Parson, and Pecchenino, QK completed the relocation, design and construction of the new main sewer pump station to the wastewater treatment plant and gravity trunk pipeline for the City of Atwater.

APPROACH

The existing lift station and alternative site were analyzed to accommodate a short timeline for bidding, equipment delivery, and construction to meet a deadline imposed by the Regional Water Quality Control Board on the City.  The evaluation of the existing lift station and alternative sites resulted in a site that allowed for additional expansion and reached the goal of no conflict to adjacent commercial property.  The efforts of the design team and tight communication with the contractor reached the other goal to complete the lift on time and within the funding budget for the client.  The new facility enhanced the reliability of the facility by adding a generator, improved electrical service and odor control facilities.

KEY ISSUES

The city’s existing wastewater treatment plant was replaced by a new tertiary treatment plant. The new treatment facility was located 5.7 miles to the south of the community and provided additional capacity for future growth.  The new lift station as designed to handle the existing flows along with growth up to a flow of 12 million gallons per day (MGD).  The new site location was chosen to provide avoidance from existing and future commercial development adjacent to the site.

RESULTS

The pump station and odor control facility was completed in February 2012 prior to the deadline for the new wastewater plant to be online by the Regional Board and within the funding budget so no additional City funds were required for project completion.
