City of Adelanto Wastewater Treatment Plant Upgrades

Adelanto, California

The City of Adelanto WWTP receives an average flow of 1.8 MGD, of which only 0.5 MGD can be treated with the existing plant in its current state.  PACE is providing engineering design and consulting services to construct new infrastructure and rehabilitate existing systems to not only regain the original plant capacity, but to increase the rated capacity to 4.0 MGD.  PACE is the engineer-of-record as part of PERC Water’s Design-Build-Operate team. New infrastructure includes new screening and washing systems in the headworks, all new aeration and blower equipment in the existing secondary basins, two new 70’ diameter circular clarifiers, an RAS/WAS pump station and new internal recycle pumping on the biological process.  Modifications will be made to the existing effluent filters and chlorine contact basin to produce full Title 22 compliant recycled water as well as improvements to the solids handling to reduce cake volumes and improve dewatering performance.
