Welcome to the Official Web Site of Indianapolis and Marion County, Indiana

The Crooked Creek Area Sewer Improvements (Belmont North Relief Interceptor) project, one of the city’s largest initiatives to improve public infrastructure, will create additional sewer capacity to accommodate population growth and thousands of homes connecting to the sanitary sewer.

The Belmont North Interceptor, which carries sewage to the city's treatment plant, serves the populations of Center Township, western Washington Township and northeastern Wayne Township.

In recent years, development in these areas has pushed the capacity of the interceptor beyond its limits. The Crooked Creek Area Sewer Improvements project will install the new seven-mile Belmont North Relief Interceptor to alleviate capacity problems. Additional space also will allow thousands of homes to abandon failing septic systems, and connect to the sanitary sewer as part of the Septic Tank Elimination Program (STEP).

Planning, design, construction and inspection for the project are estimated to cost approximately $58 million, and the project will be complete in late 2011.

Through a process called value engineering, the Department of Public Works (DPW) has identified efficiencies that will allow the city to save approximately $50 million in capital project costs and reduce energy use during construction.

Project Benefits

• Alleviate capacity problems in the Belmont North Interceptor, which are due to population growth.
• Increase the capacity of the sanitary sewer with a new relief interceptor, allowing for thousands of homes to connect to the sanitary sewer through STEP.
• Reduce inflow and infiltration of stormwater into the sanitary sewer.
• Improve water quality in Crooked Creek and the White River by adding capacity needed for homes to abandon failing septic systems, which leach sewage into the groundwater that flows to waterways. Homes will connect to the sanitary sewer through STEP.
