Municipality
The Town of Minto provides clean, safe drinking water to more than 2,108 people in the Harriston area. Your positive actions can help to keep that water safe and clean.
Impacts of Plans
Your local source protection committee, for the Maitland Valley and Ausable Bayfield areas, has prepared drinking water source protection plans. The Province of Ontario has approved these plans which took effect in April of 2015.
These plans help to keep your drinking water safe. Plan policies may require action from you if you are located in municipal wellhead protection area (WHPA) zone A, B or C. Please click on the map link for wellhead protection areas. Please visit our Plans page for information on policies and their impacts.

Where Does the Water Come From?
The three municipal wells draw groundwater from an aquifer. Aquifers collect water underground much like a sponge collects water. The municipality draws that water from underground through the municipal wells.
How is the Water Treated and Distributed?
The Town of Minto uses chlorination and iron sequestration to treat the water. Operators must adhere to strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. Ontario Drinking Water Quality Standards require compliance.
How is the Drinking Water Source Protected?
Ontario’s Clean Water Act, 2006 was created to protect drinking water at the source as the first of several barriers of protection. Other barriers of defence include monitoring, distribution, and the three Ts (testing; treatment; and training of water operators).
