The City of Richmond Hill’s drinking water comes from two main sources: Lake Ontario and groundwater wells. Protecting these water sources from contamination is essential to ensure a clean, safe, and reliable water supply for the community.
Everyone, including developers, businesses, residents, and municipal planners, has a role in maintaining water quality and quantity. By understanding the potential threats and regulatory requirements, interested parties can help safeguard Richmond Hill’s drinking water sources for future generations.
What is Source Water Protection?
The Clean Water Act, 2006, was created to ensure the protection of present and future sources of drinking water by:
- Identifying vulnerable areas and potential threats to drinking water
- Implementing Source Water Protection Plans and policies to maintain both the quantity and quality of drinking water
In Richmond Hill, the Central Lake Ontario, Toronto Region, and Credit Valley Source Protection Plant (CTC SPP), has been guiding these efforts since December 31, 2015.
What activities threaten drinking water sources?
- Municipal: winter maintenance and road salt, waste, sewage, and stormwater
- Agricultural: biosolids, manure, commercial fertilizer, pesticides, livestock grazing
- Commercial: fuel, organic solvents, dense non-aqueous phase liquids (DNAPLs)
- Residential: septic systems, private wells, and fuel storage
- Water taking: activities that take large quantities of water from the ground
