4th Street Steam Line Repairs

 
 

Project Timeline - Updated

05/10/2019 - 06/22/2019 

Rain events at the end of May and early June have delayed work on the steam line beneath 4th Street SE in Rochester. However, the project is moving forward steadily. Work is complete along 4th St SE at 7th Ave SE and 11th Ave SE. Restoration work remains at 6th Ave SE, 13th Ave SE, and 14th Ave SE.

Weather permitting, all intersections are expected to be open by 06/22/2019. We appreciate the public's patience as we work to restore traffic flow to the area.

Project

The Olmsted Waste-to-Energy Facility (OWEF) supplies steam for heating and cooling to buildings on the Olmsted County District Energy System (DES). Nearly two miles of pipe—most of which is buried underneath 4th Street SE in Rochester—connects the OWEF to buildings on the western end of the DES. These buildings include the Olmsted County Government Center, Work Release Center, Rochester City Hall, Rochester Public Library, Rochester Art Center, and Mayo Civic Center.

Leaks have been discovered at various locations along the 26-year-old steam line causing plumes of steam to rise out of manholes at several locations along 4th Street SE. Repairs are necessary.
