Approximately 5,000 people in Kemptville are supplied with drinking water provided by the Municipality of North Grenville. There are three municipal wells constructed between 1948 and 1979. In 2012, the provincial government provided funding to the municipality to undertake a project to better protect the wells. This involved extending the well casings so that water is drawn exclusively from a deeper, less vulnerable aquifer.

Where does the water come from?

The municipal wells draw groundwater from the Nepean Sandstone Aquifer which is well-known for supplying a good volume of quality drinking water.

How is the water treated and distributed?

Each well is located inside a pump house where chlorine is added to disinfect the water. Treated water is then pumped into the distribution system. Each pump house also has an on-site reservoir for storage of water for periods of peak demand.

How is the water treated and distributed?

Raw water from the river is pretreated and screened to remove solids. Water then enters rapid mixing chambers where a coagulant and polymer are added to bind the fine particles together forming “floc”. Fine sand is added to help the floc settle quickly in the two settling tanks. A collection hopper at the bottom of each settling tank collects the floc while the clear water flows into collection troughs at the top. Water then passes through filters, is disinfected using chlorine gas and then fluoride is added before the water enters the distribution system.
