Collection System Improvement Project

The City of North Olmsted will be undertaking a project to address overflows caused by Inflow/Infiltration (I/I) intrusion into its sanitary sewers during intense rainfall events.

The project includes:

  • 6,250 feet of parallel relief sewer construction of new sewer lines ranging in size from 12-inch to 24-inch.
  • Rehabilitation of the 4.5 million gallon per day (mgd) LeBern and 7.9 mgd Dover pumping stations, including pump replacement, metering and the addition of grinders.
  • 360,000 gallon underground equalization tank at Dover Pump Station.
  • Expansion of the 1.5 mgd Clague Park equalization tank influent pumping station to 7.5 mgd.
  • 1.25 million gallon underground equalization facility at Clague Park.
  • Approximately 900 feet of relief sewer ranging in size from 15-inch to 24-inch along Chapel Hill Drive.
