The discharge of prohibited, restricted and hazardous waste into the sewerage system may have adverse effects on human health, the environment, drainage infrastructure, treatment plants and the beneficial use of wastewater biosolids. In addition, these substances may result in the violation of federal or provincial legislation, guidelines and codes of practice. Bylaws prohibiting these harmful practices and an industrial source control program are strong deterrents against the discharge of harmful substances at the point of origin.

The EPCOR Drainage Services Bylaw 18100 and the City of Edmonton Drainage Bylaw 18093 specifies what can and cannot be released into sanitary, combined and storm sewer systems. EPCOR’s Monitoring and Compliance program consists of eight Industrial Wastewater Investigators that perform more than 3000 industrial, commercial and institutional (ICI) inspections each year. Part of these inspections includes responding to spill investigations and complaints from the general public. Investigators review wastewater processes, indoor/outdoor chemical storage areas, drainage fixtures, pretreatment systems, spill procedures and waste disposal documentation.

The main objective of the Industrial Source Control program is to promote educational awareness with ICI’s through regular inspections and collaborative conversations. Where educational awareness is not effective, additional enforcement actions are required such as the issuance of fines or discontinuance of services. The information provided in this session will highlight various complexities of Source Control in a large municipal setting. Topics include: collection/treatment limitations; ICI’s to monitor; Bylaw provisions; inspection planning/processes; documentation review; education and awareness programs; overstrength surcharge program and wastewater transfer station monitoring.
