Help Conserve Water


Dear Residents,

We need your help in conserving water and maintaining the efficiency of our municipal water system. Please keep a watchful eye and promptly report any potential water service leaks occurring on municipal property, in ditches, front lawns, and other public areas. Your vigilance plays a vital role in preserving our valuable water resources.

To ensure an accurate assessment of our water infrastructure, we kindly request your assistance in identifying the following signs of water service leaks:

  1. Persistent Wet or Damp Areas: If you notice constant wetness or damp patches on streets, sidewalks, parks, or other public areas, it could be an indication of a hidden water leak.
  2. Unusual Pools of Water: Keep an eye out for standing water or pools forming in unexpected locations, such as ditches, roadways, or common areas, without an apparent source.
  3. Flowing Water in Unattended Areas: Report any instances of water flowing from pipes, hydrants, or valves that seem to be unattended or not in use.
  4. Sinkholes or Erosion: Notice any sinkholes, erosion, or unusual changes in the landscape near water supply lines or underground utilities, as it may signify an underlying leak.
  5. Unexplained Drop in Water Pressure: If you experience a sudden decrease in water pressure in your homes or observe it in public areas, it could be due to a water service leak.

Your assistance in promptly reporting these observations will greatly aid our efforts in addressing and repairing water service leaks efficiently. To report potential water service leaks, please contact the Municipality at 519-294-6244 or email us at @email.  Your cooperation is invaluable in ensuring the proper functioning of our water system.

Thank you for your commitment to water conservation and your continued support in preserving our vital resources.
