Your Water Starts Here.
The water in your glass started as a Great Lake. Huron Erie Water brings it to you.
We are a public water utility serving 15 communities across the greater London region of Southwestern Ontario. Every day, we treat and deliver safe, clean drinking water drawn from Lake Huron in the north and Lake Erie in the south to the families, businesses, industries and communities that depend on it.
Two Lakes. One Standard.
Who We Are
One organization. Two systems. One standard of care.
Huron Erie Water is the shared identity of two regional water supply systems. Each draws from its own Great Lake, serves its own communities, operates its own facilities, and maintains its own independent governance. Together, with Huron Erie Water at the centre, they form a single accountable organization with one standard holding them both.
We are not a reactive utility. We plan ahead, aligning infrastructure and capacity decisions with municipal growth before the pressure arrives, not after. The region is growing. The communities we serve are counting on us to be ready.
Lake Huron Primary Water Supply System
Serves communities to the north and west of London: Strathroy-Caradoc, South Huron, Middlesex Centre, Lucan-Biddulph, North Middlesex, Lambton Shores, Bluewater, and London. The plant has a current treatment capacity of 340 million litres per day (75 million Imperial gallons per day) and serves a population of approximately 500,000 people.
Elgin Area Primary Water Supply System
Serves communities to the south of London: St. Thomas, Aylmer, Bayham, Central Elgin, Malahide, Southwold, Duttton Dunwich and London. The plant has a current treatment capacity of 91 million litres per day (20 million Imperial gallons per day) and serves a population of approximately 150,000 people.
What We Believe
Everyone deserves safe, clean drinking water.
That belief shapes every decision we make: how we plan, how we invest, and how we hold ourselves accountable to the communities that depend on us.
Water is not something people should have to worry about. The confidence you feel when you turn on a tap is earned every day by holding two systems to the same exacting standard, and by never letting where you live determine the quality of your water.
How We Work
From source to tap, every day.
- Regional Treatment and Supply: Two treatment facilities. One quality standard. Safe water from source to system, every day.
- Long-Horizon Planning: We plan years ahead so communities grow without outgrowing their water supply.
- Transparent Governance: Accountable to every community we serve: publicly, consistently, and by name.
- Plain-Language Communication: When something affects you, we say so clearly: which system, which communities, what it means.

More Information
The Lake Huron and Elgin Area water systems each have an Environmental Management System registered to the ISO 14001 international standard. Under the Safe Drinking Water Act, the Ontario Ministry of the Environment, Conservation and Parks (MECP) requires that each drinking water system have an accredited operating authority. In order to be accredited, the operating authority and the drinking water system must establish and maintain a Quality Management System.
Each of the municipalities supplied by these systems are responsible for water distribution to their residential, commercial and industrial customers. For more information about the water quality in your area, please contact your local municipality.
