Hydrant Flushing

Fire hydrant with water coming out

The City of Thorold's fire hydrant flushing program occurs on an annual basis every spring to ensure hydrants operate correctly and to help maintain good water quality. As part of the annual program, City staff will turn hydrants on to circulate water in city water mains. This may cause minor changes to the water consistency and pressure. This issue should be resolved by running cold water for a few minutes until the pressure returns to normal. If the water does not return to normal after a thorough tap flush (approx. 10 minutes), residents are asked to call our Public Works Department at 905-227-6613 x266 for assistance. 

The city is divided into three areas, in which City staff conduct hydrant maintenance:

  1. Decew System Area
  2. South End System Area
  3. Port Robinson System Area
