Fire Hydrants 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 use your water for an hour or two.  Then, turn your cold water on and let the water run for one minute to clear the water out.

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 of time.
  • 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. Easy to install and saves water by restricting the flow to 4 gallons per minute (which is adequate 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 spigot only as needed. This will save from four to five gallons per day.
  • Check your toilets. Does the tank overfill and waste water through the overflow pipe? Check the seating valve on the bottom of the flush tank: is it seating completely to avoid wasting?
  • 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 commode tanks.
