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.

Abstract:
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.
Trenchless Technology Canada Magazine
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.
National Guidelines & Standards:
Barbara chaired this important standard published by CSA. This Guideline covers measures to reduce the risks of basement flooding, and to mitigate the adverse effects on property, public safety, and public health in case of a flood event. It covers existing, new, rebuilt, and renovated houses in rural and urban settings.
This is the first national sewer guideline published in Canada. Barbara prepared the draft, and worked with a national stakeholder committee to revise and finalize this seed document, which has since developed into a National Standard of Canada (BNQ, 2023)
This is the second national sewer guideline published in Canada. It was conceived of, drafted and brought to fruition at the federal level. Barbara chaired the national stakeholder committee that worked together to finalize the document, which was published in 2021. This document is being developed into a National Standard of Canada from 2023 -2025 (BNQ).
Barbara was a key contributor to this guide. The guide provides detailed and practical information on foundation drainage systems, sump pump systems, backwater protection for foundation drainage systems, and private-side sanitary sewer connections. This document covers components found in Part 9 of the National Building Code of Canada.
