Cornwall ON – For the third straight year, the City of Cornwall’s Water Purification Plant has scored a perfect inspection rating from the Ontario Ministry of Environment.

“These results confirm that the citizens of Cornwall enjoy drinking water that is second to none,” said Mayor Bob Kilger. “City staff is committed to maintaining the safety and quality of our drinking water, and residents can be confident that we are on the right track.”


The City of Cornwall received a 100 % inspection rating in the Chief Drinking Water Inspector’s Annual Report for 2009-10, which was recently released to the public.

Cornwall’s drinking water system has undergone significant investments in recent years, including a $10-million upgrade to the Water Purification Plant in 2006. Work is currently underway on a $1-million project to upgrade filters at the Purification Plant.

“These ongoing investments will ensure that residents and businesses continue to have access to a high-quality water supply for years to come,” said Owen O’Keefe, Water Purification Plant Supervisor.
