Municipal Water Supply System

Municipal Water Supply Systems

Approximately 90% of Sarnia-Lambton residents obtain water from treatment plants. These plants draw water from the head of the St. Clair River and from Lake Huron inlets located at Bright’s Grove and Grand Bend. Potable water(suitable for drinking) is provided through six stages of treatment; it is then pumped through some 350 km of pipeline which extend throughout much of the county.

Lake Huron is the drinking water source for 129,000 County residents.
