Institutional, Commercial & Industrial Services
The City of Markham delivers clean, safe drinking water to commercial and industrial users!
We’re proud to maintain our state of the art water distribution system. Through a system of pipes, valves, hydrants, pumping stations, and reservoirs, we deliver high quality, reliable drinking water to our businesses and industries.
Minimize the Risk of Contaminating Markham’s Drinking Water
Our city’s backflow prevention bylaw reduces the chance of water contamination through backflow incidents at cross connections.
Protect our Sewer Systems, Streams, and Lakes
City laws regulate what can and can’t go into our sanitary and storm sewer system. Our Sewer Use By-law has defined limits for substances such as pH, oil and grease, suspended solids, and more.
