Wastewater Systems Effluent Regulations Reporting

The Effluent Regulatory Reporting Information System (ERRIS) allows regulatees to submit various reports required under the Wastewater Systems Effluent Regulations (WSER).  It will utilize Environment Canada's Single Window system where WSER regulatees establish user accounts, manage their organization information and connect to ERRIS.

Requirements for monitoring, record-keeping, reporting and toxicity testing are specified in the Regulations.  Note that the identification and monitoring reports listed below must be submitted by the following dates:
