Adjustments to pH and alkalinity of regions drinking water in June 2021

Metro Vancouver has notified UBC Vancouver that they are planning to increase the pH and alkalinity of the region’s drinking water through the use of natural minerals in early June 2021. This increase in pH and alkalinity is an important step in a long-term program to reduce pipe corrosion from naturally occurring elements in drinking water.

An exact date has not been confirmed, however, a reminder from Metro Vancouver will be sent to UBC two weeks prior to adjustments —the week of May 24, 2021.

The following user groups may be impacted:

  • UBC Facilities — Boiler operators
  • UBC Faculty —Research operations
  • UBC Hospitals and Health care units — Dialysis Centres and equipment
  • Athletics & recreation — Aquatic Centre
  • Student Housing & Community Services — Food Services and laundries


This adjustment is part of Metro Vancouver’s ‘Corrosion Control Program: Copper Pipes Protection’. For more information, including details and background of their project, please visit the Metro Vancouver website or review the project fact sheet.


For questions or concerns, please contact your building’s Facilities Manager.
