Wastewater Treatment Equalization Tank, University of Connecticut — Storrs, Connecticut

The University of Connecticut, with a student population of more than 20,000, had a wastewater treatment plant which could not adequately treat peak daily wastewater flows. LEI worked with the University to design an equalization tank that would store flows which exceeded process capabilities and re-pump these flows back into the head end of the plant during off-peak hours.

A four-compartment, one million gallon capacity tank was constructed with diffused course air bubble aeration system to keep the raw sewage aerobic while maintaining constant motion in the tanks to prevent solids from settling. The 80-foot X 70-foot equalization tank is 15 feet deep and has two flow-control pumps.
