Tap Water

Thirsty? Tap the tap!

Clean and safe drinking water is a basic requirement for our body’s survival.  It is vital to ensure that our water sources are safe and reliable for everyone today as well as in the future.

You can survive up to one month without eating food, but only a week without water. Water makes up 60% of your body.

London’s municipal drinking water is delivered to your home from two Great Lakes (Huron and Erie) through hundreds of kilometres of pipes, booster stations, storage reservoirs and water treatment plants.  A typical London resident is delivered water to any tap or fixture in their home 24 hours a day, 7 days a week.

For just over a $1 a day, a resident of London receives water to fulfil all of their household water needs (hygiene, sanitation, cooking, laundry, yard maintenance and fire protection).  To put that into perspective, residents receive ALL of their daily water needs fulfilled for less than the cost of one bottle of drinking water purchased at the store.

On the go? Taps for your bottles!

Certain parks and City buildings have water fountains that can be accessed to drink or refll a bottle from. We've included as many of these as we can on a map that allows private organizations to share their publically accessible refill locations. Take a look at the map by going to and entering London into the map's search bar.

(Please note that this map is managed by an external party, and as anyone can contribute to it, we won't have much information on any non-City related facilities).

Did you know?

  • More than 130 substances are routinely tested to safeguard the quality of the City’s water - providing results which are better than drinking water standards
  • London residents receive 1,550 glasses of water from the tap for the same price as a bottle of drinking water from a store.

Small things you can do to make a big difference:

  • Drink water from the tap as much as possible, rather than consuming bottled water.  You'll save money and reduce the number of bottles ending up in our landfill.
  • Keep in mind that it takes a lot of energy to deliver water from the Great Lakes to our homes which are over 40 kilometres away, but bottled water can have an even longer trip.
  • Drink at least 3 litres of water a day to maintain body hydration.
  • Use only the water you need.  For example, do not run the tap while you brush your teeth.

Drip, Drop - It costs a lot

  • Check for leaks regularly.
  • Leaks waste water, and money, every second of every day until they are repaired.
  • Repair leaky faucets easily by replacing the washer which costs very little.
  • Always turn off your taps tightly so that they do not drip.

Sink savings

  • The kitchen sink is a hub of activity in any home. Water is used for a wide range of activities such as washing dishes, rinsing fruits and vegetables and cleaning your kitchen counters. Most people are unaware of how often they leave the tap running while performing these day to day tasks. Becoming more aware will help you save water and money.

Did you know?

  • Installing an aerator on your kitchen tap can reduce your water usage by 25-50%.
  • Only 9% of a Londoner’s water use occurs in the kitchen, which is minimal compared to the 54% that is used in the bathroom

Small things you can do to make a big difference:

  • Insulate household water pipes to ensure hot water is delivered to your faucet.
  • When washing dishes by hand, don't wash or rinse dishes with running water. Instead consider using options such as a dish tub or plugging the sink. 
  • Use the least amount of detergent possible to minimize the amount of rinse water needed.
  • Don't let the faucet run while you clean vegetables. Rinse them in a few centimetres of water in a sink or pan.
  • Never pour water down the drain when there may be another use for it such as watering a plant, garden, or for cleaning around your home.

Other water saving tips:

  • Keep a container of drinking water in the refrigerator. This addresses the wasteful habit of running tap water to cool it before drinking.
  • Save water from cooking vegetables and use it for soups and gravies, or use it to give your houseplants a drink once the water is cool.
  • Boil vegetables using just enough water to cover them.  Steaming vegetables not only uses less water, it conserves more nutrients.
  • Soak your pots and pans instead of letting the water run while you scrape them clean.
  • Kitchen sink disposals require a lot of water to operate properly. Instead, start a compost pile as an alternate method of disposing of food waste.
  • Use a pail or basin instead of running water when cleaning your home
  • Do not use running water to thaw meat or other frozen foods.  Instead, defrost foods overnight in your refrigerator or use the microwave’s defrost settings.
  • Install an instant water heater in your kitchen so you don't have to run water for it to heat up. This also can reduce heating costs in your home.

Environmentally speaking...

  • Make sure water is the only thing going down your drain. Never put garbage down your sink - such as cooking fat and grease, paints, solvents, household cleaners, pesticides and other chemicals that are very harmful to the environment and your home plumbing.
