ENHANCED TREATMENT AND SITE UPGRADE PROGRAM - PHASE 1A AERATION BASIN
MODIFICATIONS (CONTINUED FROM FRONT COVER)
Union City, CA. The project consists of a complete overhaul of existing Aeration Basins 1 thru 7 to include selective demolition
for new concrete wall configurations and cast-in-place suspended decks, coatings, piping, equipment, and controls. Other
scope items include a New Electrical Switchgear Building, East and West Odor Control Structure replacement, a new blower and piping
upgrades in the East and West Blower Buildings and pump rehabilitation as well as replacement in Lift Stations 1 and 2. Ancillary work
includes earthwork, process piping, ductbanks, and site improvements.
The ETSU Program was developed to meet the wastewater treatment and disposal
needs of the Union Sanitary District (USD) over the next 20 to 40 years. Key drivers for
this project: Secondary Treatment process performance requiring immediate upgrades
and a plan for increasing solids treatment capacity and meeting anticipated nutrient
regulations; The need for effluent management options with the anticipated shutdown of
the Hayward Marsh; building/facilities in need of seismic upgrade and repair; and limited
land available onsite for addressing these priorities.
