Water pressure is largely provided by gravity from higher elevation resevoirs. Vancouver is divided into a number of areas by elevation in order to maintain reasonable water pressures.
The City also operates 30 pressure reducing valves, and one combined pressure reducing valve-flow regulation valve station to further control water pressure.
Help protect our drinking water quality
In larger complexes, Vancouver requires backflow prevention assemblies to be installed to protect drinking water from contamination by the backflow from water used for other purposes:
- Fire sprinkler systems
- Underground lawn irrigation systems
- Commercial boiler systems
- Residential and commercial boiler systems with anti-freeze
Backflow prevention assemblies have internal seals, springs and moving parts that can wear out. Backflow prevention assemblies must be tested after installation, and tested annually by a certified tester, in accordance with the Vancouver Water Works Bylaw 4848.
Submitting backflow assembly test reports
Effective July 1, 2019, we'll no longer accept paper copies of backflow assembly test reports for existing or replacement backflow tests.
We've contracted Backflow Solutions, Inc. (BSI) to manage an online database management system for tracking backflow test results and information. There is currently no fee to file a City of Vancouver test report with BSI.
Only 3% of the world's water is fresh, and less than 0.33% is available for human use.
Whether you turn on a faucet or set out your sprinkler, the water that spills out is fresh, potable water.
