The City of Markham limits outdoor water use in the summer. These limits happen between June 1 and September 30 every year. They apply to all residential owners, tenants, and lessees.
Here are the rules:
During summer months, water use more than doubles. The City needs to make sure that it has enough water to meet demand. By reducing how much water we use during peak hours (10 AM to 5 PM) we can help our infrastructure last longer. It reduces construction, operation, and maintenance costs. It also helps us lower the cost of providing reliable and safe water to our community.
If we reduce the amount of water we use during peak hours (10 AM to 5 PM), we prolong the lifespan of our current infrastructure and helps manage operational costs.
A reliable water supply helps ensure drinking water reserves, adequate water pressure, and fire protection. By reducing our use of treated water during peak hours, water will be there when we need it.
The water used outdoors from sprinklers, hoses, and driveway car washing runs off into storm sewers on your street. It can pick up all sorts of pollutants along the way. Contaminated water that goes into our storm sewers flows directly into Lake Ontario without being treated. Reducing outdoor water use can reduce the pollutants that end up in our drinking water source. Plants, wildlife, and aquatic animals need a clean lake, too!
The City actively looks for people who aren’t following the water restrictions. We hand out notices to residents that don't follow Water Use By-law 2019-53.
There are some exemptions to Water Use By-law 2019-53
