What to expect

  • Homes and businesses where water mains are to be cleaned will receive a notice before cleaning begins 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 flushing periods, and water may appear discoloured.
  • No chemicals are used in cleaning and flushing. 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 that 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.
