The City will begin fall water main cleaning in selected areas of Guelph on Monday, October 23. There are three parts to the cleaning program:
- Nightly cleaning: from October 23 to November 3, between 10 p.m. and 6 a.m.
- Daily flushing: from November 6 to 16, between 8 a.m. and 4 p.m.
- Daytime cleaning: November 19 from 8 a.m. to 6 p.m.
The City aims to complete all cleaning and flushing by the end of November.
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.
