Underground Water Services

Copper water services are renowned for providing trouble-free service for decade after decade.

In many Canadian cities where older neighbourhoods still have lead or galvanized steel water services, programs are in place to systematically remove and upgrade these services. Some of the service replacement programs are tied in with water efficiency or conservation initiatives, such as the installation of water meters.

Many municipalities have lead water service replacement programs including Montreal, Ottawa, London, Winnipeg etc.
