What You Own and What the City Owns Before setting a maintenance schedule, know what you are responsible for. In Northern Utah municipalities — Ogden, Kaysville, Layton, Salt Lake City — the homeowner is responsible for the sewer lateral from the house to the city main, including the tap connection. The city maintains the main itself. If a blockage or failure is in your lateral, it is your problem and your cost. That is why a maintenance schedule matters: you are maintaining your own infrastructure, not waiting for the city to do it.
Start with the normal pattern: wastewater should move away from the fixture, through the branch line, into the larger building drain or sewer lateral, and out toward the public or private collection system. Most confusion starts when one symptom is judged without locating where that pattern is breaking down.
For sewer cleaning and maintenance questions, the useful first step is separating a local fixture issue from a deeper line condition, because those two situations can look similar at the surface but lead to different next steps.
