# Water infrastructure management and rehabilitation > Live situation record from CLSTR: https://clstr.news/situations/water-infrastructure-management-and-rehabilitation > Updated: 2026-10-12T16:11:50.000Z. Sources: 5. Developments: 2. Water infrastructure management focuses on the critical role of piping systems, such as PVC and CPVC, in transporting clean drinking water. To ensure safety for human consumption, these materials must comply with international standards like NSF/ANSI 61. However, aging infrastructure remains a major challenge, with an estimated 6 billion gallons of treated water lost daily in the United States due to leaks and pipe breaks. To address these issues, utilities are evaluating whether to rehabilitate, expand, or replace existing facilities based on structural condition and regulatory requirements. Emerging trenchless rehabilitation methods, such as Cured-in-Place Pipe (CIPP) and slip lining, are being utilized as alternatives to traditional open-cut replacement. These technologies can reduce total project costs by 30% to 60% and significantly lower environmental and global warming impacts compared to conventional excavation. ## Timeline ### 2026-10-12: Water infrastructure management: Rehabilitation vs. replacement Utilities are increasingly weighing rehabilitation against replacement for aging water infrastructure, with trenchless technologies offering significant cost and environmental savings over traditional methods. 2 sources. https://clstr.news/cluster/water-infrastructure-management-rehabilitation-vs-replacement ### 2026-09-28: PVC and CPVC piping systems support water infrastructure PVC and CPVC pipes are essential for safe water transport, though U.S. communities lose 6 billion gallons of treated water daily to leaks and aging infrastructure. 3 sources. https://clstr.news/cluster/pvc-and-cpvc-piping-systems-support-water-infrastructure --- Cite as: Water infrastructure management and rehabilitation.
