Understanding Richmond Hill's water
Source: York Region, average hardness Q2 2026.
Where does Richmond Hill's water come from?
Richmond Hill is supplied by York Region with Lake Ontario water (via Toronto and Peel), plus groundwater wells in some northern and rural areas. Municipal treatment meets safety standards, but many homes experience:
- Hard water (York Region average 127 mg/L)
- Chlorine taste and odour
- Iron and manganese staining in well areas
- Tannins in fringe wells
Softened water keeps scale out of water heaters and appliances, helping them run efficiently and last longer.
