Backflow-Cross Connection Control

To make sure the water we drink is safe and clean, the Town of LaSalle has criteria that must be followed. If you own property, you can connect to the Town’s water, but you have to follow the Backflow-Cross Connection Program. 

Cross Connection and Backflow Prevention By-law 7847 protects drinking water quality. Backflow is when water flows the wrong way. It happens because of two things: Back Pressure and Back Siphonage.

  1. Back Pressure: Imagine a private water system pushing harder than the Town’s water supply. That can make water go backward.
  2. Back Siphonage: Sometimes, the Town’s water pressure is weaker than a private system’s pressure. This can cause water to flow the wrong way between public and private systems.

There are different types of devices to prevent backflow, depending on the risks. These devices need to be checked by a certified contractor every year to make sure they work correctly. The certified contractor will fill out and submit a Backflow Prevention Report Form.

If you have further questions regarding the program please contact one of the following:

Community Water Fluoridation

Fluoride is a naturally occurring mineral that exists in nearly all water sources. Ground water dissolves the fluoride from rocks into the soil and water. Drinking fluoridated water is linked with reduced tooth decay.

Community water fluoridation (CWF) is the process of monitoring and adjusting the level of fluoride in drinking water to optimize the dental benefits of preventing cavities. Research has shown that the optimal level of fluoride for cavity prevention is 0.7 milligrams/liter (mg/L) or 0.7 parts per million (ppm). CWF is a global strategy to reduce dental cavities, as many communities around the world have access to CWF.

Internationally, many public health agencies have endorsed CWF, including the World Health Organization, the Canadian Dental Association, and the Public Health Agency of Canada (PHAC).

CWF is a cost-effective and equitable method to provide fluoride to the population. This population based preventive intervention contributes to oral health equity by overcoming common social determinants of health including age, education, income, and access to professional dental care. For more information on CWF, visit the Government of Canada's website and the Windsor Essex County Health Unit's website.

Background Information

  • In 2013, the City of Windsor and the Town of Tecumseh voted to remove community water fluoridation (CWF) from Windsor, Tecumseh, and LaSalle.
  • In March 2019, the Windsor City Council passed a by-law to reintroduce fluoride to Windsor's water system.
  • In April 2019, the Town of Tecumseh Council voted in favour of reintroducing fluoride to the water system.
  • In January 2022, ENWIN Utilities Ltd. (ENWIN), on behalf of The Board of Commissioners of the Windsor Utilities Commission (WUC) reintroduced fluoride into the local drinking water systems for Windsor, Tecumseh, and LaSalle.

Fire Hydrant Flushing and Maintenance

Periodically, the Town of LaSalle Water Division carries out fire hydrant maintenance and flushing of water mains. This work takes place March through October. During this time, there will be some pressure drops and discolouration of the water.

Should any water customers note any discolouration of the water in their residence, please do not turn on the taps for an hour or two.  Then, run the cold water taps until the water clears.

Water Conservation Tips

  • Repair all leaky faucets, especially hot water faucets, as quickly as possible. You'll save water and energy too. A dripping faucet can use up to 170 gallons in a 24-hour period.
  • Be sure your dishwasher is full but not overloaded when you turn it on. An average dishwasher uses 14-16 gallons of hot water per load.
  • Washing dishes in running water before placing them in the automatic washer is an expensive luxury.  This can add dollars to your monthly water bill. Scrape them, but do not let the water run.
  • Install a flow restrictor in your shower. It is easy to install and saves water by lowering the flow to 4 gallons per minute (which is enough for showering). Remember, using more hot water than you really need wastes both water and electricity (or gas).
  • Don't let the water run while you shave. Turn on the tap only as needed. This will save from four to five gallons per day.
  • Check your toilets. Does the tank overfill,  wasting water through the overflow pipe? Check the seating valve on the bottom of the flush tank: Is it seating Properly?
  • A good test for spills in the toilet system is to put a little bluing into the flush tank.  If the bluing shows up in the bowl (without flushing), water is being wasted. It is our estimate that about 90 percent of all high-water bills are caused by malfunctioning tanks.
