Capital Improvement Project Number 650695
This project implements recommendations in the city’s Wet Weather Management Plan.
This project will rehabilitate approximately 1,124 lineal feet of 24" combined brick sewers, 5,519 lineal feet of 48" combined brick sewers, and the associated manholes within the project area. These sewers were constructed circa 1867-1883, and were identified to be in bad condition. The rehabilitation of these sewers will enhance structural integrity and extend service life, as well as eliminate sources of infiltration, thereby reducing flows to the treatment plant and to the downstream CSO regulators within the project area.
This project will also construct new storm sewers to remove surface water from the combined sewer system, thereby reducing flows to the treatment plant and to the downstream CSO regulators within the project area.
Finally, this project will construct a new sanitary sewer to remove all wastewater flows from an existing combined sewer and convert it to a dedicated storm sewer. This will result in the elimination of a combined sewer overflow.
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 $4.5 million.
Construction is expected to begin in March 2012 with completion expected in December 2013.
The main project benefit is a reduction in combined sewer overflow volumes into the Scioto River during an average year of rainfall. A reduction in both frequency and volume of combined sewer overflows is achieved by redirecting stormwater out of the combined sewer system and into a dedicated storm sewer system.
An additional benefit is the extension of the service lives of the sewers. The Cured-In-Place Pipe (CIPP) rehabilitation process will extend the life of the sewers by 50 years at a minimum.
Project location is generally along Fulton Street, between Washington and Fourth Streets; Mound Street between Washington and Fourth Streets; and Noble Street between Washington and Grant Avenue.
