Six Design Considerations When Rehabilitating an Existing Pipe

America’s Wastewater Infrastructure is currently rated at a D+, according to the 2025 ASCE Report Card for America’s Infrastructure. The Wastewater category includes both piping for the collection systems and the wastewater treatment plants the piping leads to. The collection system alone experiences 3.3 failures per 100 miles of pipe every year, putting pressure on maintenance teams to identify suspect pipes for either complete replacement or pipeline rehabilitation. This article will focus on the design and construction considerations necessary when a pipeline owner determines they will be rehabilitating an existing pipe.
