Water System

Lake Erie and Lake Huron

London is situated between Lake Huron and Lake Erie. These two fresh water lakes are the source of London's supply of clean water. We are the beneficiaries of an abundant source of fresh water and an efficient delivery and treatment system. London's water system is a natural icon and a source of life.

Our water comes to us through a network of treatment plants, reservoirs, pumping stations and pipes - 1,550 km of pipes - that was initially constructed in the 1870's. Since then it has been maintained and improved and serves us now well into the future, if we are prepared to do our part. It is our responsibility to make sure it is kept up.

Operating and maintaining our water system - ensuring that the quality of our water meets all regulated standards, planning for the future renewal of the treatment/storage/delivery network and safeguarding our water supply - comes at a cost; the price we pay for our water should allow the water system to operate efficiently and be maintained on a cost recovery basis.


Our Mission:

To provide valued water service to our customers, through the delivery of safe, clean, high quality drinking water of sufficient flow and pressure to enhance the quality of life and support economic development for the residents and businesses of London.
