What is a sewer-use by-law?
A sewer-use by-law is a tool developed by a province and/or municipality to control inputs to the sanitary sewer system. Industrial discharges to the sewer are identified and certain substances are limited by quantity and quality and time of discharge so not to disrupt the normal flow patterns or upset the treatment process. Substances to be monitored will be dependent on the type of industrial input (i.e. high technology versus chemical manufacturing, etc.). The industry may pay a sewer surcharge to the municipality to have their waste accepted. This is an excellent tool to assist in reducing contaminants to the environment either directly to water or through use of Biosolids.
