Save water and help the environment

Twenty-four percent of household water is used by the toilet - Think of all the money you are flushing down the drain!

Why install a high-efficiency toilet?

  • It's the law. Effective October 3, 2011, the Province of British Columbia amended the BC Building Code regulation, requiring the installation of 4.8 litre or less high-efficiency toilets.
  • They're reliable. New high-efficiency toilets have proven to be efficient and reliable. Read more about choosing a toilet.
  • Save water. Your family can save over 30,000 litres of water a year with a 4.8 litre high-efficiency toilet. That's a significant reduction in household consumption.

From 1999 to 2009, the CRD offered water efficiency rebates to encourage the purchase of appliances and fixtures that use innovative water-saving technology. These days, the use of such fixtures and appliances has become industry standard - and the law, resulting in CRD rebate programs ending.

High-efficiency toilets are:

  • Available in a wide range of styles and colours.
  • Easy to install and maintain.

Effective October 3, 2011, the British Columbia Building Code regulation was amended to require the installation of high-efficiency toilets and urinals in all new residential buildings and renovation projects involving toilet replacements in British Columbia.

Under the updated regulation, new residential buildings and renovation projects, involving toilet replacements must include high-efficiency toilets with a 4.8-litre flush volume or less. Toilets which provide a dual flush cycle option of both 4.1-litres or less and 6-litres are compliant. Urinal installations remain unchanged, with the maximum flush volume of 1.9-litres or less. The amendment will result in residents using water more efficiently, extending the life of existing water supplies and making water available for other uses.

These new requirements will apply to buildings used for Group C, residential occupancies only. Group C occupancies include houses, apartments, hotels, motels, lodging houses and dormitories. For more information, please contact your local building inspector.

How can I tell if a toilet is low-flow or high-efficiency?

Low-flow and high-efficiency toilets look like other models, but may have a smaller tank. Toilets must be marked to indicate they have been tested for low flow water consumption. Look for toilets marked with one of the following: "LC," "4.8," "LC/4.8," "LPF" or "xLPF" where x indicates tested value in litres per flush and is equal to or less than or 4.8 litres.

Planning for high-efficiency Installations

If you are planning a construction or renovation project, pick up the “High-Efficiency Toilets - For a lifetime of Savings” brochure from the CRD or at local plumbing retailers and home improvement stores. You can also refer to the links on the side panel to get further information.

Like any consumer product, not all toilets are created equal. The Maximum Performance Testing of Popular Toilet models (called the MaP study) is an independent toilet evaluation study available to help you make an informed choice.


Make the right choice

Like any consumer product, not all toilets are created equal. Consumers are advised to talk with their plumber or plumbing supplier. Independent test results of high efficiency toilets are available through the American Waterworks Association.
