The Ontario Ministry of Transportation has included polypropylene pipe for gravity flow sewer water applications in the December 2, 2013 publication of the Ontario Provincial Standards (OPS). Adding to the already approved use of high-density polyethylene (HDPE) pipe in diameters of 100 to 1500 mm, the newly published standards and specifications denote dual and triple wall polypropylene (PP) pipe.
"We are pleased that the Ontario Ministry of Transportation's Design and Contract Standards Office has incorporated the criteria for dual and triple wall corrugated polypropylene gravity sewer pipe, 320 kPa, into the new edition of the Ontario Provincial Standard Specification (OPSS) and Ontario Provincial Standard Drawing (OPSD)," said Ewout Leeuwenburg, ADS senior vice president of international operations. "This is an important advancement for greater, open competition for communities who want to maximize their systems as polypropylene pipe has been proven to reduce costs and extend service life.
The Ontario Provincial Standard Specifications include OPSS 1843, Material Specification for Non-Pressure Polypropylene (PP) Plastic Pipe Products; OPSS 410, Construction Specification Pipe Sewer Installation in Open Cut; OPSS 421, Construction Specification for Pipe Culvert Installation in Open Cut; and OPSD 806.030, Height of Fill Table.
These standards have been developed for use in provincial and municipal contracts. The administration, testing, and payment policies, procedures and practices in these documents correspond to those used by many municipalities and the Ontario Ministry of Transportation.
