What to expect

  • Homes and businesses where water mains are to be cleaned will receive a notice 48 hours before cleaning starts on their street.
  • Tap water should not be used during cleaning times. Store tap water before cleaning starts or use bottled water.
  • Water pressure may be low during cleaning, and water may appear discoloured.
  • No chemicals are used in water main cleaning. Special scrubbers and water pressure are used to clean water mains.

Drinking small amounts of discoloured water is unlikely to cause health issues. However, the City recommends waiting until water runs clear before drinking it. To clear discoloured water, run a cold water tap for five to fifteen minutes.

Why we clean water mains

Water main cleaning ensures customers receive the freshest water possible. Cleaning removes buildup of natural minerals such as iron and manganese. This reduces the chance that water will become discoloured.
