The city of Ottawa is has begun a backflow prevention program to protect the drinking water quality by making sure that the appropriate backflow prevention devices have been installed and inspected on private property in the Ottawa area. These devices prevent contaminated water from flowing back into the city’s water system; they are currently in place in many other municipalities in Ontario. This program will not affect an enormous amount of people, but it will impact approximately 15,000 commercial, institutional and multi – residential properties; apartments, hotels, hospitals, automotive and manufacturing facilities etc. Ottawa has very strict water safety guidelines and standards and everything has to be under CSA compliance.
Your city’s drinking water flows from the Distribution system onto your private property. Backflow, to make it simple, is when unclean water flows back into the city’s distribution system, which can cause contamination. This may be caused when the back pressure in a private system is greater than the city’s water supply system. Back siphonage happens when the city’s system is lower than pressure in the private system; the pressure can pull bad water back into the city water distribution.
Property owners will begin to be notifies in 2018, and there are compliance laws and timelines that will have to be followed. Surveys will have to be done, backflow prevention devices will have to be installed and certain deadlines will have to be met in accordance to City of Ottawa compliance.
There is certain testing that will need to be carried out to determine whether the severity rating is high or moderate. The City of Ottawa will also request site surveys every five years, as well as annual backflow device testing. A qualified Ontario Water Works Association (OWWA) surveyor will be necessary to carry out site surveys and install these devices.
