Major Sewer Improvement Effort

22nd Street Sewer Augmentation

Pima County and its contractor, KE&G Construction, Inc., will begin work on the 22nd Street Sewer Augmentation project which extends from Alvernon Way to Swan Road. This work is necessary because the existing pipe is at or near its maximum flow capacity. This project will increase sewer volume and improve the lifespan of the sewer infrastructure in the area.

Construction will take place along 22nd Street from Alvernon Way to Swan Road, including both the Alvernon Way and Swan Road intersections.

This project consists of:

  • Installation of approximately 1-mile of new 12-inch sewer between Alvernon Way and Swan Road
  • Rehabilitation of sections of the existing 10-inch sewer along the south side of 22nd Street
  • Removal of the existing 8-inch sewer along the north side of 22nd Street 
  • Relocation of the 36-inch water line crossing the 22nd Street and Alvernon Way intersection

The project team will utilize the Construction Manager at Risk (CMAR) approach, which combines the efforts of the design engineer, the owner and the contractor working together as a team to complete the sewer pipe augmentation.

The project is scheduled to begin early 2016. The traveling public should expect delays and lane closures when driving, bicycling, or walking in the area. For your safety, please observe all traffic control signage, message boards and obey reduced speed limits.
