In this episode of the Infrastructure Network, host Chad Smeltzer is joined by Michael Simpson and Barbara Robinson to discuss the persistent problem of sewer infiltration and inflow (I&I). They explore the reasons why I&I continues to plague sewer systems and the challenges faced in addressing this issue. The guests emphasize the importance of public education, proper data management, and the use of technology to tackle INI effectively. They also highlight the need for a shift in mindset and the adoption of new approaches in the industry.
Key Takeaways:
Public education is crucial in addressing I&I, as many residents are unaware of their responsibility for maintaining their private sewer laterals.
Traditional methods of flow monitoring and modeling are not effective in finding and fixing I&I. A more targeted and localized approach is needed.
Technology, such as Electroscan tools, can provide actionable information about the condition of sewer pipes and help prioritize repairs.
Municipalities should consider the true cost of I&I, including the impact on wastewater treatment plants, when making decisions about infrastructure investments.
