Water main swabbing 

The Town of Newmarket uses a variety of industry-approved techniques - including watermain swabbing – to do a thorough cleaning of watermains that, over time, see a build-up of sediment. 

Watermain swabbing involves inserting a foam sponge – or 'swab' – into the watermain through a fire hydrant. The diameter of the swab is slightly larger than the watermain, and it is pushed along through the watermain using water pressure. As it passes through, the swab clears any sediment that has built up inside the watermain. The swab is then pushed up and released through another fire hydrant.

The Town always does its best to reduce impacts to Newmarket residents and businesses. However, during the cleaning process, some residents' usage may be impacted for a short period of time. Residents in the affected households are notified at least 24 hours in advance that watermain cleaning will be taking place on their street, and are provided with information on what to do with their water while they wait.
