Scope:

Note: The standard designation for this NOI (originally published on May 9, 2023) was updated by the responsible SDO on May 16, 2023.

Purpose and scope: The standard is intended to implement a mitigation program to mitigate inflow and infiltration (I/I) in existing sanitary sewer systems, including the identification of the sources and evaluation of I/I flows, the determination of appropriate levels of service, the collection and analysis of data, the devlopement of I/I mitigation strategies and elements of an intervention plan. This new standard is intended for the following main groups: municipalities, organizations and regulatory authorities in charge of the sanitary sewer systems, engineers and planning services. These groups will easily find the measures relevant to their fields of activity on sthis standard.

Project need:

Inflow and infiltration (I/I) is an issue affecting sewer systems throughout Canada. An excessive I/I rate creates flooding in urban environment that leads to numerous adverse consequences, namely on the environment, as well as health and safety of the population. I/I has significant and permanent financial impact for municipalities, insurers, taxpayers and owners. This standard will allow municipalities to understand how significant I/I is for their system before investing public money in studies and field rehabilitation work and to be proactive in managing the sewer system. This new standard will provide the users with the guidelines enabling them to adopt a modern approach in I/I management by the implementation of an efficient and cost-effective I/I mitigation program.
