In this article, Norton presents some best practices for reducing private side I/I. The new national sewer standard seed document, "Developing an Efficient and Effective I/I Program" (Norton & ICLR, 2021), emphasizes how essential a private side I/I program - 60% of our I/I occurs on the private side.
This article contains Norton's practical applications research since the development of the standard.

Pluvial flooding in urban areas is one of the most significant drivers of disaster loss in Canada. Damages during pluvial flood events are associated with overwhelmed urban drainage (stormwater and wastewater) systems. During the period from 2013 to 2021, Canadian property and casualty insurers reported approximately CAD 2 billion in personal property (residential) pluvial sewer backup claims during flood catastrophes. There has been growing interest in managing pluvial urban flood risk.
Inflow and infiltration (I/I) has received limited attention in the pluvial flood literature, however. Informed by significant engagement with practitioners in Canada, this paper provides a review of the issue of I/I into wastewater systems and its relation to pluvial flooding. The paper will address concerns related to private property engagement in I/I and urban pluvial flood reduction programs. Bothimproved technical standards and administrative support are needed to ensure that wastewater infrastructure is less susceptible to I/I over its lifecycle.

In this article, Norton discusses the key role that the trenchless industry will play in repairing/replacing private side laterals, as public education of residents improves, and residents begin to understand that they can reduce their risk of flooding by simply having a CCTV inspection of their lateral, and taking appropriate steps, if necessary.
This practise will reduce private side I/I substantially!
This article contains practical, efficient and cost-effective solutions to private side I/I.
