Summary

The City of Sarnia delivers safe and clean drinking water to Sarnia residents through a system of watermains, known as the Municipal Drinking Water System.  The Safe Drinking Water Act and the regulations of the Ontario Ministry of the Environment and Climate Change (MOECC) require the City of Sarnia to provide safe drinking water to all of its residents, otherwise known as the Standard of Care. 

In order to keep the drinking water safe and protect public health, the City is working on a proactive plan towards preventing contamination of the drinking water system from incidences of backflow.  This plan includes creating a Backflow Prevention Program and passing a Backflow Prevention By-Law to enforce the program.
