CAN/BNQ 3682-320/2023

This standard applies to both public and private sanitary sewer systems. NOTES — 1 Private sanitary sewer laterals are installed on private properties in order to collect sewage from the sanitary sewer pipe of residential (single-family dwellings, multi-unit dwellings), commercial, institutional and industrial buildings, and any other types of property where the sanitary sewer system is not public. 2 The installation of a private sanitary sewer system is generally subject to construction requirements specified in construction codes or municipal by-laws. This standard does not apply to sanitary sewer systems installed in special conditions such as permafrost or shallow bedrock (Canadian Shield). This standard does not apply to combined sewer systems. NOTES — 1 A combined sewer system includes pipes that collect and transport both sanitary sewage and other sewage from residential, commercial, institutional and industrial buildings, and facilities and stormwater through a single-pipe system. 2 A combined sewer system should not be used from an I/I reduction perspective. This standard only covers aspects related to I/I mitigation risks in new sanitary sewer systems. This standard does not cover all aspects related to the design, construction, maintenance and operation of new sanitary sewer systems or to the inspection and testing as part of its construction. NOTE — Regulatory requirements in place in some provinces and territories may be similar, complementary or different from the requirements described in this standard. Users of this standard requiring information on other aspects related to the maintenance and operation of new sanitary sewer systems or to the inspection and testing as part of the construction of new sanitary sewer systems not identified in Chapter 1 shall refer to other documents. This standard is intended for regulatory authorities and owners of public and private sanitary sewer systems. It is also intended for real estate developers, residential building owners, property insurers, material manufacturers and suppliers, and sanitary sewer construction contractors.
