Sacramento Regional County Sanitation District Awards CH2M HILL Contract to Design Primary Effluent Pumping Station

DENVER, October 30, 2013 – CH2M HILL (, a global full-service consulting, design, construction and operations firm, has been awarded a contract by the Sacramento Regional County Sanitation District (Regional San) to provide design and services during construction for the new primary effluent pumping station at their Sacramento Wastewater Treatment Plant. The project is part of SRCSD's $1.5-$2.1 billion EchoWater Project, a major effort to upgrade Regional San’s wastewater treatment facilities to be the most advanced in California.

Regional San provides service to approximately 400,000 residents in Sacramento County and West Sacramento; the regional treatment facility, near Elk Grove, processes effluent from 1.4 million people in the capital area.

When completed, the EchoWater Project will allow Regional San to meet the State of California’s treatment requirements by producing cleaner water for discharge—removing nitrogen and ammonia from wastewater before it enters the Sacramento River. Additionally, the Project provides Regional San more water reuse and recycling opportunities for irrigation.

Under the contract, CH2M HILL will design the new Primary Effluent Pumping Station to provide the necessary lift within the existing plant’s process stream to accommodate the new treatment process. The project also includes extending the existing primary effluent (PE) channel, constructing new diversion pipelines to connect the PE channel to the emergency storage basins, rerouting existing dual 72-inch diversion lines via a new juncture structure to an 84-inch chlorinated final effluent line, and controlling odors within the new facilities.

“We have worked with Regional San on their interceptor program for years. The EchoWater Project will bring Sacramento’s wastewater treatment to a new level and protect the region’s waterways for future generations,” said Phil Ryan, CH2M HILL Project Manager. “We are looking forward to contributing to this monumental effort.”
