Summary
The purpose of this project is to rehabilitate the Lift Station 40 force main in accordance with the Lift Station 40 Ahwatukee Force Main Condition Assessment Report dated June 2016 and the subsequent rehabilitation design dated February 2019. The force main conveys wastewater from Lift Station 40 near I-10 and Ray Road to a discharge structure near Guadalupe Road and I-10. The force main has three 24-inch-diameter ductile iron pipes. A 2016 condition assessment report concluded the entire length of the oldest force main pipe, and portions of the other two pipes, were in need of rehabilitation.
