The Clean Water Act requires municipalities, conservation authorities and watershed residents to work together to protect sources of drinking water, primarily sources of municipal drinking water. This will be achieved through Source Protection Plans, which will be written locally, approved by the Minister of the Environment and implemented by municipalities, Ministry of the Environment and/or Conservation Authorities.

The documents lay out how a Source Protection Plan will be developed for the each watershed. It is a two step process: (1) produce an Assessment Report, (2) develop a Source Protection Plan.

Terms of Reference were prepared for the Rideau Valley watershed and Mississippi Valley watershed.
