Sahuarita Slipliner Project

摘要

This project involves rehabilitating approximately 36,000 LF of abandoned 36- and 30-inch concrete cylinder pipe (CCP) water transmission main with High Density Polyethylene (HDPE) plastic pipe slipliner. The project goal is to rehabilitate the abandoned transmission mains to convey approximately 10.0 mgd of additional renewable potable water resources from the Santa Cruz Well Field. The project is located in mixed-use industrial and rural residential areas of southeast Tucson, Arizona. The 36- and 30-inch CCP transmission mains were installed in the 1960s, and were abandoned due to maintenance issues including corrosion and leakage. Slip lining the abandoned transmission mains with HDPE pipe was selected by the City of Tucson Water Department (Tucson Water) as the most cost-effective and least disruptive technology to develop the requisite conveyance facilities.
