Upshur Shaft

Updated July 28, 2017

This summer, Environmental Services installed a valve and underground vault on NW 11th Avenue between NW Northrup and NW Overton Streets. The equipment will reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. This project will help to ensure the sewer system operates safely and efficiently.

Construction Has Been Completed

The project was located near the busy intersection of NW 11th and Northrup. Construction began the week of July 18 and took two weeks to complete. This included time to set up, install piping and structures, and then restore pavement disturbed during construction.

Crews worked at the manhole in the street and install piping that connects to a new underground pressure valve and vault structure. There were temporary traffic restrictions, including reduced lanes and assistance from flaggers. Parking was temporarily removed around the work area during construction.
