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.

Beiderbecke

10/07/20

Canadian Pacific rail restoration along Beiderbecke has been delayed to mid-to-late October.  One complete, the contractor will return to the area to finish work on the 1930's sewer abandon.

08/21/20

Most of the sewer work in an near Beiderbecke has been completed. Additional work will occur when Canadian Pacific finishes the rail restoration project in the same construction zone. Beiderbecke is expected to remain closed through September and possibly into October. 

06/12/20

1930’s Sewer Interceptor work off of Harrison St between River Dr and Beiderbecke will wrap-up today, Friday, June 12th.  Work will transition to Beiderbecke nearer the LeClaire Bandshell and between Ripley. More mini-project locations will be scheduled when work near the Bandshell is complete.

Keep in mind Beiderbecke is essentially closed between the LeClaire Bandshell and its east extents, and will remain closed for most of the summer due to sewer improvements and railroad crossing restoration activities.  Pedestrian access remains available.  Some parking is available off of River Dr, on side streets north of River Dr, and at City parking ramps.

Work to disconnect from the 1930’s sewer interceptor is continuing south of River Dr, near Beiderbecke and LeClaire Park. Work will continue in the area through mid-June, before moving to later phases. As a reminder, multiple mini-projects will take place along the riverfront as new structures are installed to divert sewer flow off of the 1930’s interceptor, to the 1970’s interceptor. The project is scheduled for completion in the spring of 2021.

04/15/20

There are several mini projects that will occur along Beiderbecke as this project progresses.  Most recently sewer was disconnected from the 1930's interceptor near Modern Woodman Park.  Additional projects will occur along Beiderbecke, with a more significant closure to be scheduled near LeClaire Park Band Shell for the installation of a new sewer main.

River Dr | Warren and Gaines St

08/18/20

Work to abandon from the 1930's Sewer Interceptor will close River Dr between Warren and Gaines St beginning Thursday, August 20.  This part of the project will install a new sewer main. The closure is expected to last through the end of October. 

River Dr @ Oneida

10/07/20

Most work in this area is complete. Late fall over over the winter/spring the contractor will return for finish work. When work resumes as a next phase, lane reductions on River Dr will be required. 

08/21/20

Lane closures on River Dr at Oneida have started as directional boring and new sanitary sewer lines are installed as part of the disconnection project.

Project Abandons 1930's Sewer Interceptor

10/07/20
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.
