​Zero pressure tests are part of the City’s rollout of pressure management infrastructure. Advanced pressure management allows the City to reduce pressure fluctuations in the network that create stress on pipes over time. This reduces the likelihood of leaks and bursts. The test is done to determine if there are any unmapped inflows into an area to inform the calibration of a pressure reducing valve, which is used to control water pressure.

Site C will not be affected.

Businesses and residents are advised to store water in clean, sealed containers for use during this period and also to ensure that their taps are closed to avoid water loss and/or damage when the supply is restored.

The City regrets any inconvenience caused.
