2ND STREET SEWER REHABILITATION (8th-16th Ave N)

July 12, 2021

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, plans to rehabilitate the aging regional sanitary sewer pipe along 2nd St N between 16th Avenue North and 8th Avenue North in Minneapolis (see project area map below). MCES identified several areas of deterioration and structural issues with the sewer pipe, which was originally installed in 1932.

This work will include installing a temporary aboveground wastewater conveyance system from 16^th Avenue North to 7^th Avenue North, rehabilitating the sewer pipe and maintenance access structures between 15^th Avenue North and 8^th Avenue North, and cleaning and inspecting a section of sewer to prepare for a future rehabilitation project. between 8th Avenue North and 3^rd Avenue North in Minneapolis.

Most of the rehabilitation work will use the cured-in-place pipe (CIPP) method which inserts a liner into the existing pipe structure to form a new pipe (see image below). This method minimizes aboveground impacts and reduces costs when compared to a full pipe replacement.

What to expect during construction

Partial closures of 2nd Street North. Local access will be maintained, but there will be short-term driveway closures to install temporary pipes. Drivers should follow posted detour routes.
Sidewalk and bike lane closures. Bicyclists and pedestrians should follow posted detour routes.
Temporary parking restrictions along 2nd Street North.
Dust, noise, odors, vibrations, equipment staging, and visual impacts in and around the work area.

What is a temporary conveyance system?

Aboveground temporary wastewater conveyance pipes will be installed to ensure that there are no disruptions to sewer service while crews rehabilitate the sewer pipe. These pipes will convey sewer flow around the work site during construction.
Some temporary conveyance pipes may be buried under driveways or roadways to maintain access and minimize disruption. Property owners will be notified in advance if this is necessary. Diesel pumps with noise dampening equipment (low noise) will run 24 hours a day, seven days a week as part of the temporary wastewater conveyance system.
