Point Washington WWTF Upgrade and Flow Equalization
This project involved upgrading the existing 0.75 MGD Advanced Wastewater Treatment Facility to a capacity of 2.0 MGD and reusing existing tanks as post-equalization tanks and aerobic digesters. Components include a rotating drum screen, teacup degritter, dual sequencing batch reactors, flow equalization, rapid sand filtration, and high-level disinfection. Another phase of this project involved installation of a 750,000 gallon influent equalization tank to dampen seasonal peak flows into the WWTP. Components include fully automated aeration and mixing equipment and a line-up of six 20 Hp submersible pumps. Firm’s responsibility included historical flow analysis, process design, hydraulic design, pump selection, permitting, and engineering services through construction, and construction administration of the project.
