Our who owns my sewer line page is built on Metro Code §15.40.050 — the homeowner owns the sewer service line from the public main to the house, all of it, with Metro's narrow right-of-way relief sequence behind it. Read that page from a Madison address with one correction held in mind: the ownership instinct is the same everywhere in this region — the lateral on your property is yours to maintain — but the §15.40.050 machinery, the two-foot cut at the right-of-way boundary, the signed release, the free residential repair of the right-of-way segment, is Metro's programme for Metro's system. Madison customers work through MSUD's own rules and MSUD's own crews for anything on the public side, and the district's number — 615-868-3201 — is the one to start from. The utility on your bill decides which phone tree is yours. It sounds like a small thing until you're two calls deep into the wrong one with sewage standing in the shower.
What doesn't change across the district line is the pipe in the ground. Madison built out through the same 1950–79 window as the rest of post-war Nashville, and homes of that period typically sit on cast iron laterals now deep into the material's published lifespan ranges — corroding from the inside, narrowing with scale, catching roots at any joint the street trees can reach; our research names Madison, alongside East Nashville and Donelson, among the neighbourhoods where root pressure from street trees is the standing pattern. The era-based cautions are identical: cleaning fixes clogs in sound pipe, descaling earns its money on scaled-but-solid iron, and no tool fixes a line that's collapsed or rotted through. The camera doesn't care which utility district it's in. Neither does the tree.
