"Developing an Efficient and Cost-Effective I/I Program"
Robinson and Sandink for SCC, 2021
The second national standard on I/I, developed for municipalities
Norton and ICLR, working with an expert stakeholder committee from across Canada, have developed the first-ever national guidance document on addressing I/I in existing sewer systems. With the help of this practical guideline, municipalities can start to find and fix I/I now, by using the data, tools, people and resources that are already available to them. Norton wrote the draft document.
Standards Council of Canada has retained BNQ to develop this seed document into a National Standard of Canada.

Private Side I/I MUST be addressed in a Modern I/I Program
It is agreed across North America that private side I/I probably accounts for 60% of all I/I. And yet, our industry has been largely unsuccessful at removing it. It's time for a modern approach to I/I, and better public education, so that residents understand why it must be removed.
Scroll through a few slides on the topic.

Sewer models do not help to find and fix I/I, and are very costly.
I/I studies frequently involve the preparation of an extensive sanitary sewer model, which is either not used, or not used correctly, by the municipality afterwards. A model is a very poor and very expensive way to find I/I to fix.
The most accurate and cost-effective way to find the worst I/I areas to address is by reviewing all background information, and working with operations in wet weather to confirm worst areas. Trust me, your operators know.
