Permits

When Industrial Users Are Required To Obtain A Permit
All industrial users proposing to connect to or to contribute to the municipal sanitary sewer system shall obtain an industrial waste discharge permit before connecting to or contributing to the municipal sewer system. The program, however, only issues a permit certificate to actual dischargers that actually have an industrial waste. Many users of the system, like a retail shop or an office, may not have to obtain a permit certificate. This assessment is made during the business license application and building permit application processes. See the list below for examples of businesses that have to obtain a permit certificate.
