Underground Flow Equalization System

UFES Schedule Update – May 16, 2022

UFES Project Schedule for May 16 – May 30, 2022

We’re making great construction progress toward pollution prevention in San Mateo. Last year’s rainy season reminded all of us why our 10-year, $1 billion Clean Water Program is so essential to the future of our City.

One of the most important projects in the program is our Underground Flow Equalization System (UFES).

As a follower to this newsletter, you already know that construction is underway on our UFES at the County Event Center. Once completed, our UFES will eventually be the underground 5.3-million-gallon structure that will temporarily hold excess wastewater during storms.

The following construction work is planned for the UFES project from May 16 through May 30, 2022. (Please note, schedules can change. We will issue this update biweekly throughout 2022):

  • Inside the Event Center Site: additional concrete pours requiring after-hours approval
  • S. Delaware Street: equipment installation and removal related to pipeline work will continue
  • Saratoga Drive: The City’s contractor is rehabilitating an existing pipeline along Saratoga Drive, between South Delaware Street and the main entrance to the San Mateo County Event Center. The City has approved work from 5 p.m. until 8 p.m. Monday, May 16, 2022 through Thursday, May 19, 2022. The curing process for the pipeline liner requires 48 hours of continuous use of a generator and boiler; therefore, the City is allowing their contractor to work continuously from 7 a.m. Tuesday, May 17, 2022 through 8 p.m. Thursday, May 19, 2022.

Alerts will be sent via newsletter and text message ahead of work requiring traffic updates, work hour changes, or expected to generate excess noise at the Event Center site.
