What is Wastewater?
Wastewater is any and all water that is used in industrial, commercial or residential buildings that goes down a drain. Wastewater is produced through actions such as doing the laundry, taking a shower or even flushing a toilet. This water then flows into pipes specifically made for wastewater and enters Markham’s sanitary sewer system.
The City of Markham, its residents and businesses value our environment and its natural resources. Our stormwater management activities help protect and enhance our water resources, and maintain the continued health of our streams, rivers, lakes, fisheries and natural heritage systems. Stormwater management policies and practices also help manage the risk of flood damages in natural and urban drainage systems.
