Project Abandons 1930's Sewer Interceptor

After several years of planning and design, the City is prepared to say out with the old, as steps to abandon the City’s 1930’s Sewer Interceptor begin. The $10.3 M project will remove storm and sanitary cross-connections and decrease inflow and infiltration into the sanitary sewer system as the flow is diverted from the 1930’s Sewer Interceptor to the 1970’s Interceptor.

Moving flow off of the 30’s Interceptor will help increase the capacity for wastewater collection from homes and businesses by reducing the amount of surface water entering the wastewater/sanitary sewer collection system.

The project is estimated to take approximately two years to complete and expected to cause little disruption to property owners and visitors. Redirecting sanitary sewer lines from one system to the other should be relatively seamless and occur without a property owner’s knowledge that any work occurred.  Some temporary closures and lane reductions will be necessary during portions of the project.

What citizens might find interesting is that the project is being funded through a low-interest loan from the State’s Revolving Fund.  Interest paid on the loan will come back to the City for later re-investment in storm sewer projects.

Abandoning the 1930’s Interceptor supports future growth in the City and is a significant investment and improvement in our infrastructure.

The project also fulfills the work required under the City’s Iowa DNR Administrative Order.
