Project Name: West Area Water Quality Control Facility – Outfall Improvements

The outfall to the West Area Water Quality Control Facility (WQCF) overflow tunnel is located at the R.M. Clayton WRC at northwest Bolton Road, adjacent to the Nancy Creek Pump station. It serves the West Area WQCF tunnel and pump station which takes flows from the North Avenue, Clear Creek and Tanyard Creek Combined Sewer Basins. It is designed to release flow to Peachtree Creek when the tunnel is full to protect the pump station if the upstream tunnel influent gates fail to close at any of the CSCF facilities. While these events are very rare, the outfall to the West Area WQCF overflow tunnel is necessary to prevent excessive damage to the WQCF and/or RM Clayton WRC.

The scope of this project includes:

• Removing grout and sediment in Peachtree Creek
• Grouting the outfall foundation
• Installing a concrete plunge pool to dampen velocities in the concrete channel
• Lining the remainder of the channel to Peachtree Creek

Justification:

• Reduces erosion potential during overflow events
• Reduces operational and maintenance costs
• Facilitates regulatory compliance
