1930's Sewer Interceptor Project

There will be several closures along and adjacent to River Dr as work on this project progresses. The tabs below describe the current status of work on the sections identified.  Please be patient during project construction.  Better roads and sewers are just around the corner.

Final Phase Project Updates| Estimated Completion Summer 2021


Disconnection from the 1930s sewer interceptor will literally be hopping around the riverfront as entire sub-systems are ready for final disconnection activities. Over the next two weeks, watch for lane reductions on E River Dr near Mound. Work in the Florian Keen parking lot should be complete by mid-April as well. Pockets of activity with a focus near Marquette will continue through the summer as final abandonment activities begin to wrap-up.

Work on the 1930s Sewer Interceptor Abandon project has been steady off and on as weather allowed this winter. We are pleased to report, Marquette south of River Dr has re-opened with the completion of work in the area.  There will be pockets of activity taking place along the entire stretch of the project on the riverfront between Mound and Marquette for a few more months, with the bulk occurring out of the traveled right-of-way near Marquette Landing.  More visible short-term pieces of the project will occur near Mound and in the Freight House Farmer’s Market parking lot in a couple of weeks.  Watch for details as final construction activities resume.

Project Abandons 1930's Sewer Interceptor

Tons of progress has occurred over the last year. Once work on River Dr at Gaines St is complete, work will mainly be focused along Beiderbecke and the riverfront west of Marquette.  All work is expected to be complete by the Spring of 2021.

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.
