This notice is to inform the public of the Ministry of the Environment and Climate Change’s release of “A Guide for Drinking Water System Owners Seeking to Undertake a Backflow Prevention Program” (PIBS# 9676e and 9676f).
This guide provides comprehensive information and suggested approaches that drinking water system owners/operators voluntarily seeking to undertake a backflow prevention program could use. The guide addresses aspects pertinent to the design of water treatment units and cross-connection control considerations that may help safeguard drinking water consumers in a more standardized and consistent manner and thus further strengthen the drinking water safety net.
The guide has been developed by a working group comprised of representatives from government ministries including the Ministry of the Environment and Climate Change, Ministry of Municipal Affairs and Housing, Ontario Municipal Water Association, Ontario Water Works Association, various municipalities, Canadian Standards Association, and building, plumbing, and training groups/associations.
This guide is for information purposes only and is not intended to provide specific technical advice or mandate requirements in any circumstances.
