Water Efficiency Master Plan 2015-2025

We are currently working on a new plan that will guide our water conservation programs for several years. Visit our master plan site to see the proposed programs and give us your input.

Indoor water conservation

Toilet Replacement Program:

The $20 Region of Waterloo rebate for high efficiency toilets will be discontinued as of June 30, 2014.

The Region will process qualifying applications received by December 31, 2014. Receipts and plumber invoices must be dated before July 1, 2014.


The toilet is the single biggest user of water in the home. This is your last chance to receive a rebate for replacing an old toilet with a Region-approved high-efficiency toilet. This lets you save water and receive a $20 rebate. Check our requirements below.

Note: Landlords, churches, non-profits and businesses may also qualify for rebates. Call 519-575-4400 to register. These groups should not use the homeowner application.

Also note that it is important to check for leaks around your home. Your toilet can silently leak up to 300 litres a day and cost you a lot of money.

Water softeners

Residents of Waterloo Region tend to use water softeners since we get most of our water from the ground where the hardness can clog up pipes and harm appliances over time. But not all water softeners are the same and some use much more water and salt to remove hardness than others do. The Region of Waterloo and the City of Guelph worked together to test various softeners to rate how much salt and water they use to do their job.

Visit our Water Softener Facts website for full test reports, hardness maps and more.



Outdoor water conservation

During summer months, water use can increase by up to 50 per cent. Learn ways to use less water for outdoor activities. Click on any of the following topics for more information:

Water Conservation bylaw:

In effect from May 31 to Sept. 30. By following the Region's Water Conservation Bylaw 07-069 (and amendments), which limit outdoor water use to specific days and times, you help to reduce peak water use and limit the risk of an outdoor watering ban.

Tips for other outdoor watering activities

Rain Harvesting Week

The first annual Rainwater Harvesting Week was held from April 21-27, 2013. During this week, residents were presented with a number of rainwater harvesting options through local retailers. The advertising features also included information about stormwater credits.  Link to the special supplement online here.

Rainwater collection using barrels and harvesting tanks is a great way to save water. Check with local retailers for options available. Also check with your city public works department to see if you qualify for a storm sewer surcharge credit if you are currently using rain barrels.


Rain Barrel Distribution

April 28, 2012 marked the Region's last single-day rain barrel sale. Over the 12-year program, nearly 50,000 rain barrels were distributed to the community. Stay tuned to this site for new rainwater harvesting programming from the Region in the future. The Region of Waterloo encourages residents to harvest rainwater by purchasing a rain barrel at your local hardware store, not-for-profit sales or building your own barrel.
