Why Northwest District needs this specifically
Septic tanks aren’t part of the Nob Hill picture — this dense, historic district runs on municipal sewer, so overflow-like symptoms point to a lateral or main-line issue in the area’s original clay or cast-iron pipe.
What to know before you call
Yard contamination from a septic overflow carries the same Category 3 hazard as an indoor backup — see the septic overflow hub for indoor/outdoor assessment details. See the full septic overflow cleanup breakdown →
