Underground Flow Equalization System

UFES Construction Update – February 16, 2021

Shoring Installation along Saratoga Drive Next Week

Construction on the Clean Water Program’s Underground Flow Equalization System (UFES) is underway, and pipeline work along Saratoga Drive has begun. During the week of Feb. 22, the City’s contractor is planning to install shoring in locations along Saratoga Drive. Shoring is required before excavation and pipe installation. Approved hours for this segment of work along Saratoga Drive are 8 a.m. to 4 p.m., Monday to Friday, for the next 10 months. Construction schedules are subject to change.

Please note: Regular UFES Construction hours continue on the UFES site from 7 a.m. to 7 p.m.

During the shoring work, residents may notice some larger trucks delivering materials to the project site. While we continually strive to minimize the impacts of our work on our neighbors, you may hear some noise and feel minor vibrations if you are close to the work in the roadway.

We thank you for your continued patience and cooperation as we make steady progress towards completion of this much-needed solution for our aging sewer system.
