The Wastewater & Drainage section of the Public Works Department is responsible to monitor and maintain infrastructure for the collection of wastewater and to control the environmental impact of our storm management system.

Sewage generated by Vaughan flows through over 45 kms of sewers before it reaches the Dufferin Creek treatment plant located just east of the Pickering Nuclear Generating Station. Sewage is treated and released back into Lake Ontario. The Kleinburg area is serviced by a treatment plant operated by the Region of York.

Liquids such as engine oil, paint, and cooking oil, contaminate and clog sewers creating expensive maintenance costs and should never be poured down drains. These liquids should be taken to the hazardous waste depot at Toronto’s Keele Valley Landfill site.

Services Provided:

• clean-up of spills of hazardous materials
• investigate sewer back-ups
• investigate odours from drains
