Reactive to Resilient

This white paper examines the growing impact of infiltration and inflow (I/I) on aging wastewater infrastructure and demonstrates how proactive trenchless rehabilitation can improve system performance, reduce operating costs, and strengthen long-term resilience. Drawing on historical research, regulatory guidance, real-world case studies, and cost-benefit analyses, the paper explores strategies for identifying I/I, preventing sanitary sewer overflows, prioritizing infrastructure investments, and extending asset life. It also highlights emerging technologies, AI-driven monitoring, and sustainable funding approaches that help utilities modernize wastewater systems while improving regulatory compliance and protecting public health.
