Types of Excavation Techniques for Sewer Line Repairs

Sewer lines are an essential component of any urban area that many people take for granted. After all, the average person doesn’t worry about their sewer system until there’s an issue; then, they’re left confused, frustrated, and upset. Fortunately, sewer line repair companies have the knowledge, experience, skills, and equipment to fix any sewer line issue in a timely, cost-effective manner. They use different types of excavation techniques for sewer line repairs to ensure no further problems arise. Here are some of the most common excavation techniques they use that you should know.


External excavations consist of digging down to the sewer lines from an outdoor location. Typically, this includes natural landscapes or streets. This project can actually take less time than most expect. The average sewer line repair takes one day, and a full line replacement will take two days, given the scope and requirements. Keep in mind that although workers need to access pipes from the outside, they’re skilled and experienced to ensure no permanent damage to the landscape or surrounding structures.


Internal excavations, on the opposite end, occur inside a building or home. Jackhammers and large-industrial tools dig a hole toward the leak or broken pipe. While invasive, it results in an immediate replacement for a broken sewer line. Furthermore, internal excavations are not ideal for multiple leaks and may be more costly than external excavations. Although our team at Harris Water Main and Sewer Contractors doesn’t conduct internal excavations, they are still one type of excavation technique for sewer line repairs to know.


While another form of external excavation, re-routing sewer lines is the least invasive, it is important to understand that this process is illegal in many cities. Sewer lining replaces existing pipework with new ones through applied pressure and lining; however, it is important to understand that it is a temporary repair and will not void the need for an actual repair in the future. These projects don’t typically take as long and have little to no effect on the ground area, but you will have to spend thousands of dollars to excavate at some time in the future. Even though trenchless excavation is a relatively new form of sewer repair that does not require roads or sidewalks to shut down, most homeowners will end up spending several thousands of dollars to replace the section of lined pipe.
