SANITARY SEWER COLLECTION SYSTEM REHABILITATION PROGRAM
Project Owner: City of Tempe
Project Type: Construction Manager at Risk
Construction Dates: 01/17 to 01/19
The City of Tempe has identified manholes and collection system piping in various locations around the city that need rehabilitation. To minimize cost and disruptions to the traveling public, pipeline rehabilitation will involve the use of trenchless technologies including cured-in-place-pipe (CIPP) lining, ultraviolet light-cured CIPP lining (UV CIPP), short-length repair sleeves, mechanical seals, and constructed pipe interiors. If necessary, traditional open-cut repair methods will also be utilized on this project. Manhole rehabilitation will involve the use of precast manhole liner inserts and coatings.
GMP 1: This project included 220 LF of 36" UV CIPP lining, two manhole inserts, and an 8 MGD bypass system. Work was completed quickly and safely in a limited access area while coordinating with multiple adjacent construction projects.
