Having long recognized the issue of infiltration of sewer piping systems, the Ontario MOE has developed a specification citing the importance of tight joints for buried sewer pipes. Currently, the MOE specification for common trench installations of sewer pipe and watermains requires joints to be qualified to a hydrostatic pressure of 50 psi (345 kpa). While some sewer pipe products on the market today may not be able to meet these requirements, IPEX PVC sewer pipe will do the job.
