Water

Nine billion litres. That's how much drinking water the City delivers each year to the more than 50,926 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 Plan 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 2015 Annual Water Quality Report.

In early 2015, Metro Vancouver will be completing the final phase of the Capilano-Seymour Water Filtration Program, which will change the operating conditions slightly, and should result in filtered water from both the Seymour and Capilano sources entering the City's water supply throughout the year. The City's water system will need to adapt to these minor operating changes, and often changes can result in brief periods of discoloured (yellow-brownish) water as sediment in our watermains is stirred up. Discoloured water can also occur 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.

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 sprinklering, 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 information, the City Engineering department will conduct a system review and provide any design information based on our water system model with a projected turnaround time of one week, unless field testing is required.

Lawn Watering Restrictions

Lawn watering regulations are in effect throughout Metro Vancouver from May 15 to October 15. During Stage 1, lawn watering is permitted three times a week between the hours of 4am - 9am. See cnv.org/LawnWatering
