Low water use toilets and faucets

Water efficient (low water use) fixtures are designed to conserve water while maintaining the same level of performance as older fixtures.

Faucets, showerheads and toilets are just a few examples of fixtures available in low water use models.

All new homes and commercial construction, including renovations that require a plumbing permit, must install low water use fixtures per the Water Utility Bylaw.

Look for WaterSense labelled toilets, faucets and showerheads ‚Äčwhen upgrading fixtures. All WaterSense products are independently, third-party certified to meet standard for water efficiency as well as performance.
