Project Status

 

• The Upper Muddy Creek Interceptor (UMCI), Phase B, project began in early 2021 and was completed in fall 2022.

 

Overview

MSD replaced a 1.5-mile deteriorated section of the Muddy Creek interceptor with a new 36-inch-diameter pipe made of HDPE plastic. The new sewer, constructed along Muddy Creek Drive from Devil's Backbone Road to near Sidney Road, eliminates about 200 million gallons of sewer overflow a year into Muddy Creek from CSO 518 and overflowing manholes. The project also eliminates overflows of raw sewage from Sanitary Sewer Overflow (SSO) 1061 into Muddy Creek.

 

his project, completed as part of MSD's wet weather plan (Bridge Plan) is reducing combined sewer overflows and eliminating sanitary sewer overflows (SSOs) into Muddy Creek

 

Background

 

The Muddy Creek Interceptor is a large diameter sewer that helps convey wastewater from homes and businesses on Cincinnati's west side to MSD's Muddy Creek Wastewater Treatment Plant in Sayler Park.

 

Built in the 1920s and 1930s, the sewer is about 5.5 miles long and runs from Werk & Westbourne roads in Green Township to the Muddy Creek pump station in Sayler Park.

 

Most of the sewer was replaced in the 1970s-1990s, with the exception of a ~2.5-mile section known as the Upper Muddy Creek Interceptor or UMCI.

 

The UMCI is 90+ years old, constructed of vitrified clay, and is located in and along the Muddy Creek channel. The UMCI is currently in very poor condition with broken sections leaking sewage into Muddy Creek during dry weather days, creek water entering the pipe and taking up capacity, and significant volumes of sewage overflowing into the creek during rain events.

 

The UMCI Phase B project replaced 1.5 miles of the 2.5 mile stretch of the UMCI. As this is a partial solution, the remaining mile of interceptor pipe - located upstream of the project area - will need to be replaced in the future.
