Markham Wastewater Discharge Bylaw for Businesses
Markham, Ontario businesses that discharge to the sanitary sewer must follow municipal and regional rules to protect public health and the sewer system. This article explains who sets limits, how enforcement works, and practical steps for compliance and reporting. The Region of York operates wastewater treatment and typically controls pollutant limits through its sewer use controls, while the City of Markham enforces local connections, stormwater separation and site-level requirements that affect discharges. Read the sections below for penalties, how to apply for approvals or pretreatment, ways to report spills, and actions to take if you receive a notice or order.
