The San Francisco Public Utilities Commission has selected Emerson as the design-build contractor for a comprehensive automation project to modernise its Southeast Treatment Plant. Built in 1952, the Southeast Treatment Plant is the city’s largest wastewater facility, responsible for treating 57 million gallons of wastewater per day. During heavy rains, it has the capacity to treat up to 250 million gallons per day.

The automation project is part of the city’s Sewer System Improvement Program (SSIP), a 20-year, multi-billion-dollar investment to upgrade the ageing sewer infrastructure that serves more than 800,000 customers and ensures a reliable and seismically safe sewer system now and in the future. The Southeast Treatment Plant is responsible for treating nearly 80 percent of the city’s flows. Emerson will implement the $20 million upgrades project in five phases over 15 years – seven years of design-build followed by eight years of service and support.
