Sacramento, CA— The Lower Northwest Interceptor Pump Stations project has won the CMAA National Project Achievement Award for infrastructure projects over $100 million.

The award was presented to Psomas, the construction management team leader, at the Industry Recognition Dinner on Tuesday, October 14, during the Construction Management Association of America's national conference in San Francisco.

The primary purpose of the Lower Northwest Interceptor program in Northern California was to convey sewage from North Natomas and West Sacramento to the Sacramento Regional Waste Treatment Plant in Elk Grove. The sewage pipeline's force main design included two pump stations to deal with elevation challenges and the need to convey the wastewater over the 20-mile distance.

The two pump stations, New Natomas and South River, were combined into one project, which became the largest of the seven major projects in the $593-million program. The New Natomas Pump Station has an initial design capacity of 22 million gallons per day (mgd) with a build-out capacity of 168 mgd. The South River Pump Station has an initial design capacity of 31 mgd with a final build-out capacity of 221 mgd. The final construction cost for the pump stations was approximately $125 million.

The pump stations project also won the ASCE Sacramento Section Project of the Year award. Along with Psomas, the project team included the owner, Sacramento Regional County Sanitation District; the program Manager, Montgomery Watson Harza; the contractor, Kiewit Pacific Construction Company; and the designer, HDR.
