Thornhill customers are advised that Water Main flushing procedures will be carried out Tuesday, April 4th to Thursday April 6th on the Upper Thornhill System and Tuesday, April 18th to Friday, April 28th for the Lower Thornhill System.


This procedure is necessary to remove sediment that may be present in the water mains and to ensure the best possible water quality is maintained. During this procedure, water pressures may fluctuate and water may appear coloured or cloudy. You are advised to run your water until it clears. Your ongoing
co-operation and understanding is appreciated.
