Maintaining the integrity of sewer pipes is crucial to ensure the smooth functioning of our wastewater systems. When sewer pipes develop issues, repairs become necessary to prevent further damage and potential health hazards. Traditionally, dig & replace methods have been employed for sewer repairs. However, advancements in technology have given rise to trenchless pipelining, a more efficient and advantageous alternative. In this article, we will delve into the concept of dig & replace sewer repair, explore its drawbacks, and highlight the benefits of trenchless pipelining in most scenarios. Understanding Dig & Replace Sewer Repair Dig & replace sewer repair involves excavating the area surrounding a damaged sewer pipe to access and replace the problematic section. This method typically entails digging trenches to gain physical access to the pipe, removing the damaged segment, and replacing it with a new pipe. While this technique has been the go-to approach for many years, it presents several significant drawbacks that make it less desirable compared to trenchless pipelining. Drawbacks of Dig & Replace Sewer Repair Cost and Time Intensive Dig & replace sewer repair is notorious for its high costs and time-consuming nature. The excavation process alone requires heavy machinery, skilled labor, and permits,
