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 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!
