City of Columbus Capital Improvement Project 650737
This project implements recommendations in the city’s Wet Weather Management Plan and the Ohio Environmental Protection Agency (OEPA) Combined Sewer Long Term Control Plan – Interim (2010) Plan Update approved on March 7, 2008.
The project has been submitted to the OEPA and is expected to receive a construction loan from the Ohio Water Pollution Control Loan Fund (WPCLF). The estimated construction cost is $4.1 million.
Construction is expected to begin in April 2011 with completion expected in April 2012.
The main project benefit is a reduction in combined sewer and sanitary sewer overflow volumes into the Olentangy and Scioto rivers during an average year of rainfall.
A reduction in both frequency and volume of combined sewer overflows is achieved from modifying regulators to capture more wet weather flow for transport and treatment at the Jackson Pike and Southerly wastewater treatment plants.
Project locations are generally within an area bounded by: Dodridge Street on the north, Greenlawn Avenue on the south, High Street on the east and the Scioto and Olentangy rivers on the west.
Work will be performed at the following sites: Hudson Street regulator, Doe Alley regulator, Frambes Avenue regulator, Indianola Avenue regulator, King Avenue regulator, Third Avenue regulator, First Avenue regulator, Henry Street regulator, Chestnut Street regulator, Spring Street regulator, Long Street regulator, Broad Street regulator, Liberty Street regulator, Whittier Street regulator, Moler Street regulators, Whittier Street Storm Standby Tanks (Designed Sanitary Relief 83 and sludge manhole) and two Franklin Main sanitary manholes.
