A property with any of the following circumstances and site conditions must be connected to the public separate sanitary or combined sewer system, which are both considered sanitary sewers for the purposes of this Chapter. All connections to the sanitary sewer must be along an approved route-of-service as described in Chapter 17.32 and BES Administrative Rule ENB-4.07, and comply with City design, construction, maintenance, and operational standards.
A. Plumbing fixtures connected. As a general policy, all plumbing fixtures from which wastewater is or may be discharged must connect to and discharge into the public sewer system. Exceptions to this requirement include situations where it can be demonstrated to the satisfaction of the City that an onsite wastewater treatment system or other alternative means of sewage disposal can otherwise be lawfully permitted.
B. Public sewer is or becomes available. An existing structure served by a lawfully-permitted onsite wastewater treatment system may be required to connect at the discretion of the City, in consultation with the sanitarian, when a public sewer system becomes available. In general, any expansion, remodel, alteration, or change in use that increases the capacity requirements of the onsite wastewater treatment system will require the property owner to abandon the onsite system and connect to public sewer system.
C. Nonconforming sewer. A property using a nonconforming sewer must abandon the nonconforming connection or convert to a conforming sewer connection when noticed by the City. Requirements for converting nonconforming sewer connections are established in BES Administrative Rule ENB-4.27 (BES Nonconforming Sewer Conversion Program).
D. Source Control Manual.A property with structures or activities that are described in Administrative Rule ENB-4.26 (BES Source Control Manual) and that require drainage to the sanitary sewer must connect to the public sewer when required as a condition of a development permit or when the City notifies the property owner thereof.
E. Threat to public health, water quality, or the environment. The City may require a property owner to connect their property, structure, or activity to the public sewer system pursuant to its jurisdictional authority to protect public health, water quality, and the environment.
