Underground Flow Equalization System

UFES Project Update – September 4, 2024

UFES Project Substantially Complete

Our Underground Flow Equalization System (UFES) project has reached the milestone that our community has been eagerly awaiting – it is substantially complete! Remaining work is minimal and includes site cleanup, final pieces of performance equipment, removal of a temporary barrier at the new site entrance, and some minor landscape work around the project areas. The major accomplishment of the project is the 5.3-million-gallon UFES structure beneath the parking lot of the Event Center. Other than a small operations building, the entire structure and associated equipment is underground. The system operated successfully during preliminary tests during the last rainy season and is ready to minimize future sewer overflows.

We would like to extend our appreciation to our community for your continued patience and cooperation throughout the design and construction process.
