How Much Does Sanitary Sewer Line Maintenance Cost?

Per the quote popularly attributed to Roman philosopher Seneca, “luck is what happens when preparation meets opportunity.” Conversely, when it comes to your sanitary sewer, yuck is what happens when disregard meets eventuality. (See what we did there?) While there’s no guarantee against a sewer leak on your property, another old adage — this one courtesy of American philosopher Benjamin Franklin — states that “an ounce of prevention is worth a pound of cure.” Again, in sanitary sewer terms, swap out “prevention” with “maintenance,” and “pound of cure” with “untold quantities of raw sewage not leaking into your home or yard.”

As opposed to your water service line, which carries fresh water to your house, and storm sewer, which channels rainwater away from your house, your sanitary sewer rids your household of all that nastiness produced by the members of your household when they shower, brush their teeth, wash the dishes and, perhaps most pointedly, flush the toilet. As defined by Michigan State University: “The sanitary sewer is a system of underground pipes that carries sewage from bathrooms, sinks, kitchens, and other plumbing components to a wastewater treatment plant where it is filtered, treated and discharged.”

If proper maintenance isn’t performed over time, these underground pipes can rupture and leak. Even if you keep your line well-maintained, ground shifting, pipe separations, cracks and root infiltrations can cause problems. But keeping up with recommended sewer-line maintenance intervals helps ensure the odds are ever in your favor, per Seneca and Franklin … and that YA book series.

How Often Should Sewer Lines Be Serviced?

Homeowners should have their sewer pipes serviced at least every few years, and for large households with several residents creating a lot of sewage waste, at least every two years. This will ensure your sanitary sewer line remains free of gradual clogs and potential backups from debris buildup.

“Performing routine inspection and cleaning is the best way to keep a sewer or storm system working properly,” states Wisconsin-based trade publication Municipal Sewer & Water magazine. “Sewer systems around the world vary in many details, including the type of material for the pipe, shape, size and location. Regardless of these variables, sewer systems must be routinely cleaned to ensure safe, consistent movement of the material.”

According to the magazine, sewer cleaners use high-pressure water jetting and a high-flow vacuum force to scour pipes clean and vacuum up the material that causes would-be blockages. More severe clogs could necessitate rodding, according to the village of Glenview, Ill., “done by inserting a cutting tool into the sewer to cut away roots or blockages along the inside of the pipe.” Before committing to any work, however, have a sewer camera inspection performed to better determine the scope of work needed.

We at HomeServe advocate for homeowners to do their own maintenance and repairs wherever they are willing, able and confident to do so, but this isn’t the type of job the vast majority of people can handle themselves without proper training, expertise, equipment and safety precautions. That means you’re going to want to have at least an idea of how much a repair job is likely to cost you before you start making calls to professional sewer contractors.

The good news: Maintenance (i.e., pipe cleaning and clog prevention) on average runs between one-tenth and a quarter of the price of a full repair or pipe replacement costs.

What’s This Gonna Cost Me?

To give you an idea of what you can expect to pay for sanitary sewer line maintenance, HomeServe has calculated the average costs — both nationally and state by state — for comparison. In order to determine what’s wrong with your system, you’ll have to call someone out to diagnose the problem, which comes with its own cost. We’ve calculated that average, as well.

Below, you’ll find the average costs for sanitary sewer line maintenance in your state. All figures are based on aggregated HomeServe data reported by our network of thousands of contractors across the nation. Where insufficient data was available to determine a verifiable average, we’ve noted so.
