This summer, Environmental Services will install a valve and underground vault on NW 11th Avenue between NW Northrup and NW Overton Streets to reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. The valve will help to ensure the sewer system operates safely and efficiently.
The project is located near the busy intersection of NW 11th and Northrup. Construction is anticipated to take two weeks and occur between late June and early July. This includes time to set up, install piping and structures, and then restore pavement disturbed during construction.
Crews will work at the manhole in the street and install piping that connects to a new underground pressure valve and vault structure. There will be temporary traffic restrictions, such as reduced lanes or assistance from flaggers. Parking will be temporarily removed around the work area during construction.
Environmental Services has selected a contractor, and they are preparing for construction. More detailed information will be available this spring and summer.
In the coming weeks, we will revisit businesses and residences nearest to the project area to discuss their needs during construction (e.g., delivery and access). If we haven’t dropped by your location and you’d like to talk with us, please contact us to schedule a visit.
