Effective immediately, there's an outdoor water ban in place for residents of Barrhaven, Riverside South, and Manotick. 80,000 residents are affected. Here's a map of the affected area:
The main water pipe that feeds this area needs replacement. It was installed in 1976 and is in such bad condition that it needs to be totally replaced. And while it's been replaced, the only water supply to the neighbourhoods will be through a much smaller back-up pipe that can only handle 10% of the original capacity.
So this is bad, real bad. That 16" back-up pipe is ok for winter demand -- tooth brushing, drinking water, showers, appliances -- but nowhere near enough capacity for the high-use summer months. If water usage isn't decreased, the impact could be even worse -- as in, total loss of water supply in the area for one to three days, and a boil water advisory for two to four weeks.
So effective immediately, the city has enacted a ban on all outdoor water use including:
- Lawns and gardens
- Swimming pools and splash pads
- Pool filling and top-up
- Car washing
- All other outdoor water uses
If you live in any of the affected communities, you might want to start praying for a rainy summer.
