When rehabbing a sewer pipe, one of the first decisions you make is whether to use spot repair or end-to-end methods. To help simplify this decision, we’ve designed a Sewer Rehab Strategy Worksheet that helps municipal workers and rehab contractors make quick decisions about which approach to utilize in any given line.

Sewer rehabilitation is resource intensive. The larger and older a sewer is, the more frequently it requires maintenance, and the more costly and time-consuming that maintenance can be. Many municipalities rely solely on end-to-end (manhole-to-manhole) rehabilitation techniques like CIPP, pipe bursting and slip-lining to repair failing lines. While end-to-end methods can repair common defects in sewer pipe, in certain situations they can be overkill and a waste of time and money. That’s where spot (or point) repairs are more useful. Because of their targeted nature, spot repairs are able to address localized defects less expensively, faster, and often with less disruption than end-to-end methods. When a single line has multiple defects, however, the decision between spot and end-to-end methods requires careful consideration.

When a sewer fails, the solution is seldom cheap or easy. Digging it up can be particularly costly, as well as disruptive to residential customers and road traffic. To avoid this, methods have emerged allowing sewers to be fixed without excavation. These methods are referred to collectively as “trenchless technologies.”
No two sewers pipes are alike. Many differ significantly in terms of size (both diameter and length), pipe material, effluent characteristics, service connections, soil composition and water table. Pipes also fail in different ways: they can crack, leak, settle, erode, corrode and collapse. These failures can be localized, or they can be pervasive. Moreover, the goal of rehabilitation can vary to include:

Exfiltration is the leakage of wastewater out of a sanitary sewer system through broken or damaged pipes and manholes. Wastewater that leaks out of defective pipe joints and cracks may contaminate ground and surface water and cause a host of other problems, including pipe structure failures due to erosion of soil support, and ground subsidence due to erosion of underground soil.
