Describe your Drinking-Water System

 

Markham distribution system is an extension of the Toronto and York Region distribution systems.  Raw surface water from Lake Ontario is disinfected, treated and tested by both Toronto and Peel for microbiological, organic and inorganic parameters prior to reaching the York Region distribution system.  York Region performs independent water testing and supplies Markham through feeder mains.  Water directly from Toronto also enters Markham through feeder mains.  York Region distribution system acts as a wholesale supplier of water and provides storage and pressure boosting for the Markham system.

Markham is a distribution only system, without pumping and storage facilities.

Markham’s drinking water within the distribution system is tested for standard parameters, in compliance with the Ontario Drinking Water system regulation.  Markham’s drinking water samples are taken to the provincially-approved York-Durham Regional Environmental Laboratory for analysis.
