Increasing our preliminary treatment capacity from 250 million gallons per day (mgd) to our maximum goal of 600 mgd.
View bid details
The Clean Water Plan will increase ALCOSAN’s wastewater treatment capacity from 250 million gallons per day (mgd) to 600 mgd. Construction of a new East Headworks facility to accommodate additional wastewater is necessary. This facility is where wastewater receives the initial treatment process, including grit removal and screenings. The new East Headworks facility will adjust for additional flows by housing six grit tanks, six bar screens and a grit truck unloading station.
At the wastewater treatment plant site, a hole has been dug approximately 70 feet deep to build the foundation for the East Headworks. Over 1,900 auger cast piles are being installed. These concrete piles are drilled down into bedrock and will serve as the support system for the East Headworks.
