The Water Department provides clean and safe drinking water to residents and businesses in Middlesex Centre. Our Drinking Water Quality Management System is in place to keep our water safe.

How Water Enters your Home

Municipally-supplied water enters your home through either a ball or gate valve - the shut-off valve - before being read by your water meter.

Make sure you know the location of your shut-off valve, and keep the area around it clear. This will help you in shutting off the water supply in your home if you need to do minor plumbing repairs.

Water Conservation Tips

In Ontario, the greatest water uses in an average home are:

  • Toilet (45%)
  • Showers (30%)
  • Laundry (20%)
  • Drinking and cooking (5%)

Here are some tips and tricks to help households reduce water consumption.


Be aware of your water use, and consider ways to use less.

Around the House

  • Turn off the tap when brushing teeth.
  • Keep a jug of water in the fridge instead of running the tap to get cold water.
  • Wash your fruit and vegetables in a pan instead of running water from the tap.
  • Don’t use running water to thaw food. For water efficiency and food safety, defrost food in the refrigerator.
  • Shorten your shower by a minute or two and save up 550L per week.

Outside Water Conservation 

  • Cut grass to a higher level (5-8cm). Taller grass shades roots and holds soil moisture better than short grass.
  • Avoid children’s recreational water toys that requires a constant flow of water. Consider a small kiddie pool instead.
  • Water vegetable gardens in the morning or evening, near the roots, and by hand.
  • Install a rain barrel (with proper mosquito screening) and use it to water your lawn and plants.
  • Follow summer alternate-day lawn water restrictions.


Locate and repair leaks to save water, money and to prevent potentially costly property damage.

  • Check for toilet leaks: Add a few drops of food colouring into the toilet tanks and wait a few minutes. If, without flushing, the colour appears in the bowl, you have a leak.
  • Check for leaks in pipes and fittings: A leak of only one drop per second wastes up to 10,000 L of water annually.
  • Review our Detecting Water Leaks Checklist for detailed information on identifying leaks in your home.


Install water saving devices on existing on existing fixtures. Select water efficient devices when replacing older, water guzzling fixtures and appliances.

  • Low-flow shower head can save up to 7.5L of water per minute.
  • Faucet aerator can reduce water use by 25%.
  • Older toilets use about 20L per flush. Consider installing a low-flow toilet, which typical use only 6L per flush.
Summer Outdoor Watering Restrictions

Alternate day outdoor watering restrictions are in place for the period of June 1 to September 15 every year:

  • Properties with even numbered addresses may water ONLY on even number calendar days
  • Properties with odd numbered address may water ONLY on odd number calendar days
  • Gardens, flower beds, trees and shrubs may be watered daily by use of hand held hose ONLY
  • Newly sodded or newly seeded lawns may be watered daily for a two-week period
Water Testing & Lead

Middlesex Centre conducts regular, on-going testing for lead in municipal drinking water at water treatment plants and at residential homes. The residential testing takes place twice a year at 20 homes each time. These homes change for each round of testing.

Recent testing in residential homes (summer 2019) shows that we are below both the provincial and national safety standard for lead concentrations in drinking water:

  • Ontario Standard (Ontario Regulation 169/03) is 10 ppb.  
  • Health Canada Standard is 5 ppb.
  • Middlesex Centre recent testing (summer 2019) found an average lead concentration of 0.13 ppb at residential homes. The maximum amount found was well below the safety standard, with one home having 1.12 ppb. 

Thank-you to all the residents that have let us collect samples in their homes to date!


Volunteers Needed

We’re  always looking for more residents that are willing to volunteer their homes to test for lead in the municipality’s drinking water system. This is routine testing to ensure the safety of our municipal water system.

What’s involved? One our licensed operators will come to your home between 8 am and 3 pm. The operator will take a sample from your kitchen tap. The test takes about 45 minutes and uses less than 50 litres of water. You will get a copy of the test results for your home.

If you would like to volunteer, contact our Public Works & Engineering Department. Please provide your name and address in your email.
