Polypropylene pipe has been added to the province of Ontario’s list of approved products for sanitary and storm water sewer projects.
In the December 2013 publication of the Ontario Provincial Standards (OPS), the Ontario Ministry of Transportation has included polypropylene pipe, 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)
The specifications include OPSS 1843, Material Specification for Non-Pressure Polypropylene 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 are used 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.
The development was hailed by Advanced Drainage Systems Inc. (ADS), one of the world’s largest producers of corrugated HDPE pipe. “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,” said Ewout Leeuwenburg, ADS senior vice president of international operations. In Canada, ADS has pipe manufacturing plants in Heidelberg, Ont., and St. Germain-de-Grantham, Que., with stocking distribution yards in Morrisburg, Ont., Moncton, N.B., and Red Deer, Alta.
