To ensure the highest quality of water possible for our community, the Township of Severn will be completing a watermain swabbing program in Coldwater starting Monday, September 29, through to Friday, October 3, 2025.
What is watermain swabbing?
Swabbing involves cleaning the watermain with a foam sponge (‘swab’) and high-pressure water. These swabs are injected at a hydrant and pushed along the watermain to be removed further down the main through another fire hydrant. The fast-moving water cleans pipes, and the hydrants are left open until the water runs clear. This helps to keep your water clean, fresh, and flowing freely. This work is best performed when water services are off to the mains being cleaned.
Affected customers will receive a hand-delivered notice from Severn’s Water and Wastewater department a minimum of one day before the swabbing occurs.
The cleaning will be completed as quickly as possible and will not continue outside of regular business hours (Monday to Friday from 7:30 a.m. to 4:00 p.m.) unless necessary.
During this cleaning, your water pressure will be significantly reduced. Customers are asked not to run any water from 7:30 a.m. to 4:00 p.m. on the date of the scheduled cleaning.
