Project Name: Custer Avenue Combined Sewer Control Facility – Additional Screens

Constructed in the mid-1980s, the Custer Avenue Combined Sewer Control Facility (CSCF) receives disinfected wet weather flows from the Boulevard Regulator. Flows up to 500 million gallons per day (MGD) enter the Custer CSCF, receiving both coarse and fine screening, followed by chlorination and dechlorination. The screened flow is then routed to the East Area Water Quality Control Facility (WQCF) via a tunnel. When the Custer Avenue CSCF screening capacity or the tunnel storage capacity is reached, excess flows are diverted around the Custer Avenue CSCF to Intrenchment Creek via tipping weirs and concrete channel.

The Custer Avenue WQCF requires an upgrade to provide additional screening prior to watershed discharges of these excess flows. The screening facilities will remove floatables that are discharged over the tipping weirs.

The scope of this project includes:

• Installing additional screens upstream and/or downstream of the tipping weirs
• Installing a concrete channel
• Providing for the collection, conveyance and disposal of screenings.
• Enhances system operational reliability
• Ensures compliance with the CSCF permit requirements
