How the national mid is built

Before you enter a ZIP we use the U.S. OEWS mean wage for Septic Tank Servicers and Sewer Pipe Cleaners (SOC 47-4071): $25.72/hr (BLS OEWS May 2025). Mid estimate ≈ 2.0 hours × $25.72 × 2.25× markup + materials mid $25 (with a small regional materials factor). Low uses p10 wages × 2.0×; high uses p90 × 2.5×. National planning band: $36 – $141 – $409.

Full algebra: methodology. Markup schedule is Fairange’s published assumption, not a BLS figure.

Materials band

Published materials low / mid / high: $0 / $25 / $100 (visual/operational septic inspection for real-estate or maintenance (not full engineered design)). Baselines are Fairange editorial figures tied to public retail when we have a SKU basket; full source notes live in DATA_SOURCES and the methodology page. We dampen materials with a regional factor (about 0.88–1.18) so wages — not a fake local parts market — do most of the geography.
