Water System Flushing (October 8, 2021)

OCWA has begun flushing portions of the water distribution system in Southwest Middlesex.  Flushing will be conducted as weather and conditions permit.  The purpose of flushing is to improve water quality for customers.  However, should you experience any discolouration or sediment in your water due to the flushing activities, run your COLD water tap for 5 to 10 minutes until the water clears.

Water Discoloration Update - Tri-County Water Board (September 22, 2021)

The water quality monitoring from the Tri-County Water Treatment Plant indicates that the conditions on Lake Erie have continuously improved throughout the weekend and incoming and treated water conditions are returning to normal.  As a result, residents should already see a significant improvement to water clarity and diminished odours to what may have been experienced recently.  The Operator has started the lengthy process of flushing the distribution systems to assist in removing the discolouration from the system.  The water is regularly tested and continues to meet all provincial drinking water regulations set out by the Ministry of the Environment, Conservation and Parks (MECP).
