Residential Water Conservation

If you live in Waterloo Region and are familiar with the water capacity constraint, you may wonder if conservation can help. Reducing water use is always important because it helps manage and protect the supply we have, especially during warm, dry weather. The community has done a great job to conserve over the years, and we will keep this up with your help. Learn more about conservation below and find more information on the constraint by visiting the FAQs in the water capacity information hub.

As our community grows, we all play a role in good water management that includes conservation. We have free programs and resources including our indoor water savings tips sheet and outdoor water savings tips to help.


Book a free home water review

During a 45- to 60-minute visit, a conservation expert will assess how your household uses water. They'll identify any potential leaks and personalized actions you can take to save water.

Homeowners in Waterloo region using at least 5.5 cubic metres (m3) of water per person, per month qualify for a free home water review.

Eligibility includes:

  • You are the homeowner of the property requesting the home water review and receive a water bill from a municipality in Waterloo region
  • Residential property is a single or semi-detached home, townhome, or duplex with your own water meter
  • Water consumption is 5.5 cubic metres per person, per month or more as listed on your utility or water bill
  • Property located in Waterloo region

  1. Together, we'll review your water bill and read your water meter to better understand your concerns. Using your water bill as a measurement tool is the first step in your water-saving journey.
  2. We'll review all water-using fixtures and appliances in your home for potential leaks or inefficiencies. For homes with water softeners, we'll test your water hardness too.

  3. We'll have a conversation about how your household uses water. Before your visit, consider how much water you are using for various water-using activities. This includes how long you are in the shower, how many times you flush the toilet, etc. 

  4. Within a week of your review, we'll send you a personalized report with our findings with  actions you can take to reduce your water use. 

We may not find obvious causes of water waste when reviewing fixtures and appliances. In this case, excess consumption likely comes from water use habits or behaviours.

After completing thousands of home water reviews, we've found that people often underestimate how much water they’re using for various activities around their home.

A review helps to highlight the difference between what you perceive you’re using, and what you’re actually using. Since your water meter measures the amount of water flowing through it, we have an accurate starting point for understanding how habits and behaviours can directly contribute to your household water use.

  1. Find the water section of your utility bill.
  2. Look for the area listing “Consumption” on your bill. Water use is measured in cubic metres (m3). Note: Your utility bill may look different based on the municipality you live in.

  3. Calculate average monthly water use per person, take your monthly household consumption and divide it by the number of people living in your home. If your average monthly water use per person is 5.5 cubic metres or higher, you're eligible for a free home water review.

Note: For households receiving a water bill every two months, divide your bi-monthly household consumption by two, then divide your monthly consumption by the number of people in your home.

Example: A four-person household in the City of Waterloo with bi-monthly household consumption of 36 m3

  1. To calculate monthly household consumption, divide bi-monthly household consumption by two: 36 m3 ÷ 2 = 18 m3 
  2. To calculate average monthly water use, per person divide monthly household consumption by number of people:18 m3÷ 4 = 4.5 m3

Checking for leaks in your home

Leaks can be costly in water loss and money. Dripping faucets and other leaks can add up over time. Watch this video to learn where to look for leaks in your home.

Toilet leaks

Your toilet can silently leak up to 330 litres a day. That's about $60 a month in lost water. In many cases, replacing the flapper (the seal between the tank and the bowl) can be an easy fix. If you haven't changed the toilet flapper in several years, it is worth checking for a leak.

How to check if the toilet flapper is leaking

  1. Add a few drops of food colouring to the tank of the toilet.
  2. Wait 15 to 30 minutes.
  3. Look in the toilet bowl. If you see food colouring, you have a leak.
  4. Flush the toilet to avoid staining.

Outdoor water use

Outdoor water use, such as watering grass or gardens, filling pools and washing cars can quickly increase your water use and your water bill.

For example, watering gardens for 20 minutes every other day with a hose nozzle would use 4,500 litres of water per month and add about $25 to your monthly water bill.

Outdoor water use restrictions

The Region of Waterloo Water Conservation By-law 07-069 is in effect from May 31 to September 30. The By-law helps to lower daily water use and level off peak demands that can put a strain on the water supply and distribution system.

Smart watering tips

  • A thorough watering once per week is the best way to maintain a healthy lawn. Rain is often enough!
  • Over watering your lawn or garden is harmful, not helpful! Excess moisture can rot grass roots and creates the perfect environment for disease.
  • Watering early in the morning is best for your grass and gardens. Midday wind and hot sun will evaporate the water meant for your plants.
  • Try leaving a small container (like a tuna can) on your lawn! When the container is full, your lawn has enough water for the week. Only one inch per week encourages deep, healthy roots.
  • Brown grass isn’t dead, only dormant. It’s OK to let your lawn go dormant. Grass can live four to six weeks without water. It will bounce back!

Choose a water wise garden

  • Choose plants that don’t need much water and are suited to our local climate.
  • A layer of organic mulch helps keep moisture in the soil and provides nutrients too.
  • Use rain barrels to harvest rainwater that’s perfect for gardens and grass.

Tips for irrigation systems

  • Use a timer to not water too long, and only within by-law hours.
  • Check regularly for leaks.
  • Make sure you're not directing water onto sidewalks or other hard surfaces.
  • Consider an efficient drip irrigation system that delivers water to the roots.
  • Manual irrigation is more efficient and less expensive than an automatic system.

Rain barrels

As of 2023, the Region of Waterloo is no longer holding rain barrel sales. 

Using rainwater reduces stress on the municipal water system during the summer months from increased demand and more drought weather events. Rain barrels also help divert water from paved surfaces keeping water cleaner and reducing stress on stormwater infrastructure during rainstorms.

If you are using a rain barrel, you may be eligible for a stormwater credit on your water utility bill. Contact the City where you live to learn more.

Schedule to winterize your rain barrel once the weather gets cooler – but before the first freeze. This will prevent water from freezing and cracking your rain barrel so you'll be ready to collect rainwater next spring.

Choose a time when you’ll have a chance to set it out to dry in direct sunlight.

  1. Drain your rain barrel – open the spigot (tap) and once drained, flip upside down to drain any remaining water.
  2. Remove and clean the spigot and all hoses – hoses can split in winter temperatures, so it's best to store indoors.
  3. Clean the barrel, lid and screen – clear out any muck, algae or debris that has built up inside the barrel, on the lid and screen over the summer.
  4. Store your rain barrel – Once your barrel and accessories are clean and dry, it’s ideal to store in a garage, shed or basement. If storing outdoors, place your barrel upside down in a sheltered area. Adding a few bricks on top will prevent it from blowing away.
  5. Reattach your downspout – Don’t forget to re-connect the full-length downspout. Position the bottom of the downspout away from your foundation.

Pools and hot tubs

If you own a pool or hot tub, you know the enjoyment they can provide. It is also important to maintain your pool and hot tub properly to protect and conserve our community’s water supply.

Reducing the amount of water you use can save you money and help ensure an adequate supply of water for our growing community.

For more information on water saving tips for pools and hot tubs visit the pools and hot tubs page.
