Guelph’s municipal drinking water is delivered to customers from a municipal watermain in the street, which then connects to small underground pipes known as water service lines. These water service lines deliver treated water into the home.

In efforts to locate remaining lead services, the City of Guelph Water Services conducts verification visits where licensed City operators will visually inspect the water service and take a water sample from your tap to determine if any part of the water service is lead. There is no cost for this visit and it will only take a few minutes of your time.

Please note: Even if your internal plumbing is not lead, unseen portions of the underground pipe can be.
