Erie Street Watermain Relining

The City of Stratford is planning to rehabilitate the Erie Street watermain between Cambria Street and Monteith Avenue using a Cured-in-place pipe (CIPP) lining technology.

CIPP lining is a cost-effective trenchless solution that lines the inside diameter of the existing pipe with a composite material. The stand-alone structural liner withstands loads and internal pressures without relying on the residual strength of the existing pipe.

The CIPP lining material is designed and manufactured to meet all drinking water requirements. One of the main benefits for this innovative technology is the substantial cost savings achieved by reducing open excavation and surface restoration.

The cleaning and lining method involves two processes. The first is scraping the inside of the main to remove accumulated mineral deposits. The second part of the work involves the installation of a structural liner inside of the freshly cleaned pipe.

The project map showing the work area is available in the Documents section at right.
