Water

Nine billion litres. That's how much drinking water the City delivers each year to the more than 52,898 residents and 500 businesses who call it home.

As part of Metro Vancouver, the City receives its fresh water supply from the Capilano and Seymour watersheds. In order to ensure safe, clean, reliable water, City staff sample and test the water weekly. Watermains are flushed and cleaned annually and/or replaced or repaired as needed. Metro Vancouver's Seymour-Capilano Water Filtration Plant provides a three-phase treatment process to address potential water quality issues such as waterborne diseases, seasonal turbidity and corrosion.


Water Quality

Distribution of high quality water is a key function of our Water Utility operations. The City purchases water from Metro Vancouver and distributes it to all of our residents and businesses. We are required to meet the stringent water quality standards that are reviewed and enforced by Vancouver Coastal Health. As part of this program, water quality is sampled at a minimum of every two weeks, for testing by Metro Vancouver. The test results are summarized in our 2016 Annual Water Quality Report.

Sometimes neighbourhoods see brief periods of discoloured (yellow-brownish) water as sediment in the watermains is stirred up. This happens infrequently, but may be caused by vibrations from construction activity or from unusually high water velocity inside the watermains caused by activities such as fire suppression. Discoloured water can also occur within a building due to stirring-up of sediment in your hot water tanks, especially if only the hot water is coloured. Discoloured water is typically an aesthetic issue, and is not necessarily a health concern from Vancouver Coastal Health.

The City conducts an annual watermain flushing program to remove sediment from our watermains and minimize discoloured water events, but these events occasionally occur in all water systems.


Lawn Watering Restrictions

Lawn watering regulations are in effect throughout Metro Vancouver from May 1 to October 15. During Stage 1 restrictions, lawn watering is permitted two times a week between the hours of 4am - 9am (even-numbered addresses Wednesdays and Saturdays, odd-numbered addresses Thursdays and Sundays).

Development and Fire Flow Information

The City of North Vancouver Engineering department is continuously planning, reviewing, and implementing changes to our water system, especially due to new developments and increased demands. For new development applications requiring a new water service for fire sprinklers, please email your request, along with the following information to: FireFlowRequest@cnv.org.

Information required:

  • Applicant Name:
  • Development Address:
  • Fire System Designer Name and Contact Info:
  • Proposed Base Water Demand (l/s)
  • Proposed Daily Average Demand (l/s)
  • Proposed Maximum Daily Demand (l/s)
  • Proposed Peak Hour Demand (l/s)
  • Proposed Sprinkler Demand (l/s)
  • Required Design Information

Based on this required information, the City Engineering department will conduct a system review and provide any design information based on our water system model. These reviews usually take about 10 working days, unless field testing is required. Please note that we cannot conduct a system review without the required information.
