Our Shared Responsibility

Using less water, keeping rainwater on your property and managing what enters our storm sewer system means you are protecting your home and the environment while saving money. Whether you live in a home, condo or an apartment, find out what you can do by browsing the different parts of the house.

The bathroom accounts for roughly 50% of your indoor water use. Learn how to check for leaky toilets, tips to save water, and what not to flush or pour down your drains.

Install Water Efficient Toilets and Fixtures

Save water and money by installing low- or dual-flush toilets (4.8 L or less), low-flow showerheads (under 7.6 L/min) and faucets (under 5.7 L/min) and faucet aerators.

Toilets Are Not for Trash

Items such as baby and other wipes, dental floss and Q-tips belong in the waste basket. Return medications to the pharmacy. Learn more about what not to flush or pour down your drains.

Turn off the Tap

When washing, brushing your teeth or shaving, never let the tap run continuously. Fill a glass with water to rinse your mouth when bushing your teeth. Rinse your razor by filling the bottom of the sink with a few centimetres of water.

Fix Leaky Faucets and Toilets

To check for a toilet leak, place a few drops of food colouring or dye test tablets (available at home improvement stores) in the toilet tank. Do not flush; wait 10-15 minutes. If the bowl water changes colour, you have a leak.

Choose Non-toxic Cleaners

Protect your health and the environment by selecting environmentally friendly cleaning products that are non-toxic and biodegradable.

Don’t Leave the Water Running

Keep a jug of drinking water in the fridge. If washing dishes by hand, gather washed dishes in a rack and rinse them with a spray or in a pan of hot water. If you have two sinks, partially fill one with soapy water and the other with rinse water.

Use the Dishwasher Wisely

Only run the dishwasher when it is full, and use the energy saver or shortest cycle.

Keep Cooking Fats, Oils and Grease Out of the Drain

Fat, oil and grease can stick to and block the inside of pipes, which can lead to sewer back-ups and basement flooding. Let the grease cool and harden, and scrape it into the Green Bin. Small amounts of liquid can go directly into the Green Bin as long as there is enough other material to absorb it. Learn more on what not to flush or pour down the drains.

Use a Faucet Aerator

Install a low flow aerator on your sink faucets to reduce your water use by 25%.

Insulate Drinking Water Pipes

Insulate pipes more susceptible to freezing, especially near outside walls and in crawl spaces, the attic and garage. This can be done with foam pipe covers available at home improvement stores. Learn more about frozen pipe prevention.

 

Install a Backwater Valve to Prevent Sewer Back-Ups

Wash Clothes Wisely

Use less water, electricity and detergent by purchasing a high efficiency washing machine. To save even more, try to only do laundry when the machine is full. If you have to do smaller loads, be sure to adjust the water level on your washing machine to match the size of the load.

Collect & Pump Stormwater Away from the Basement

Foundation drains (also called weeping tiles) are pipes with holes that collect groundwater to keep it from entering your home. It is recommended that you connect the pipes to a sump pump to pump the water away from your foundation walls. More on basement flooding prevention.

Use the Water Meter to Track Leaks

Suspect you have a leak? Turn off all indoor and outdoor water use and look at your water meter. If the small red triangle on the face of the meter is turning, you likely have a leak.

Know How to Turn Off Your Main Water Supply, In Case Your Pipes Burst

Image of a main water shut-off valve on a pipe

The main water shut-off valve is typically located on the foundation wall where the drinking water pipe enters your home. Make sure you know where it is and how it works. If going on vacation, you can protect your home from leaks or frozen pipes by turning off your main water supply and opening the taps to drain water from the plumbing. See what to do if you have a leak.

Seal Cracks and Air Leaks

Stop rain and melted snow from entering your home by sealing cracks around windows, doors and in your foundation walls or floor. To keep your pipes from freezing, you should also seal air leaks around pipes, electrical wiring and dryer vents.

Ensure There is Water in Your Basement Floor Drain

Image of a p-trap with water in it

The pipe connected to your basement floor drain has a bump (called a P-trap) that retains water. This helps create a barrier, which prevents sewer odours from entering your home. In some homes, doing laundry or using the basement sink will refresh the water in the trap. If you smell a musty odour in your basement, check the floor drains and if dry, pour in a few litres of clean water.

Consider Water Efficient Plants, Trees and Vegetables

Native plants and trees are low maintenance and naturally drought-tolerant. Vegetables such as asparagus and rhubarb, and herbs such as rosemary, thyme and sage, also require minimal watering.

Replace Hard Surfaces

Replace hard surfaces such as driveways, walkways and patios with porous paving, a garden or grass. This will help absorb and naturally filter rainwater and melted snow.

Maintain a Water Efficient Lawn

Healthy lawns only need 2.5 cm of water once a week, including rainfall – use a rain gauge to keep track. Water in the morning to eliminate evaporation, and consider aerating in the spring or fall to help water reach the roots. More on water efficient landscaping.

Ensure Landscaping Slopes Away From the Foundation

Ensure the grading around your home slopes away from the foundation wall to help drain water away from your home (without negatively affecting neighbouring properties).

Practice Responsible Car Washing

Take your car to a commercial car wash; find a location where the wastewater won’t flow into a catch basin. Or, use a bucket and small of amount of water that can be emptied into a toilet or laundry sink.

Keep Chemicals Out of Drains and Sewers

Catch basins (the square grates on the road) drain straight to the lake, so it is important to keep chemicals and household waste out. Clean up vehicle spills or leaks to prevent toxins from entering the sewer. If you suspect a spill or illegal dumping, please contact 311 immediately.

Ensure Fire Hydrants are Clear

Fire hydrants must have at least 1.2 meters of space around them at all times. If you have a hydrant close to your property, please keep it clear of snow, trees and other vegetation.

Shut the Outdoor Water Supply Before the First Frost

Outdoor pipes are the first to freeze. Before the first frost, unscrew the hose and close the valve the provides water to your outdoor water supply. This valve is located inside your home on the pipe that goes through the foundation and connects to your outdoor faucet.

Unplug Catchbasins

If it is safe to do so, clear roadside leaves and other debris from catchbasins to help water enter the storm sewer. Construction waste should also be kept out to prevent sewer back-ups and harm to local waterways.

Clear Eavestroughs and Downspouts

Clear eavestroughs and downspouts of leaves and other debris that prevent proper drainage.

Disconnect Your Downspouts – It is Mandatory

Image of a disconnected downspout

You are legally required to disconnect your downspouts from the City’s sewer system. Disconnect onto a permeable surface such as a garden or grass, 1.8 meters (6 feet) from your foundation. More on downspout disconnection.

 

Run a Water-Efficient Pool

Use a pool cover to conserve heat. The cover will also reduce the amount of water (and chemicals like chlorine) lost through evaporation.

Properly Dispose of Water from Pools, Hot Tubs and Spas

Since there are chemicals used in pools, hot tubs and spas, it is important you dispose of water properly at the end of season, or before maintenance:

  • Water from chlorinated pools must be dechlorinated before emptied into the storm sewer (i.e. through a catch basin in front of your property).
  • Water from salt water pools must be released into a sanitary system through a connection on your property (i.e. bathtub, laundry sink).
  • Water from both chlorine and salt water pools can also be discharged onto grass, but only if it can be properly absorbed into the ground without flowing onto a neighbour’s property.

The pipe that brings water into your home is called the water service pipe. If your home was built before the mid-1950s, you may have lead pipes, a soft metal that can enter drinking water and pose a health risk to some people. Learn more about lead pipes.

Sewer Pipes

Image of a sanitary sewer pipe

Sewer pipes carry wastewater (sewage). They are connected to a home’s plumbing (toilets, sinks, laundry, floor drain, etc.) and lead to a wastewater treatment plant.

Storm Sewer

Image of a storm sewer pipe

A storm sewer collects stormwater from catch basins, connected downspouts and weeping tiles. It carries this untreated water into nearby streams, rivers and Lake Ontario.

Combined Sewer

In some older parts of the city, stormwater and sewage are collected in the same pipe, known as a combined sewer. During normal weather conditions, all the wastewater in the combined sewer is treated at the wastewater treatment plant.
