Polypropylene pipe added to list of products approved for sanitary and storm water sewer projects.
ST. CATHARINES, Ont. – The Ontario Ministry of Transportation has included polypropylene pipe for gravity flow sewer water applications in the December 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.
“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, vice-president of international operations at Advanced Drainage Systems Inc. (ADS), a manufacturer of corrugated HDPE pipe. The company has manufacturing facilities in Ontario.
The 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 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.
Polypropelyne pipe is designed in accordance with AASHTO LRFD Bridge Design Specifications, said Greg Bohn, ADS director of national engineering.
“AASHTO LRFD is a strain-based design procedure for buried structures and is suitable for thermoplastic pipes such as HDPE, PP, and PVC. This code considers the actual failure modes of thermoplastic pipe such as thrust, buckling and combined strain to ensure a viable design.”
ADS has pipe Canadian manufacturing plants in Heidelberg, Ont. and St. Germain-de-Grantham, Que., and stocking distribution yards in Morrisburg, Ontario; Moncton, New Brunswick and Red Deer, Alberta, along with a fleet of trucks serving rural and metropolitan areas.
The Ohio-based company has a global network of 57 plants and 28 yards, producing pipe products for farms, sports stadiums, golf courses and infrastructure projects.
