Industry Trends
Inspection Laws Expanding
More states are requiring or standardizing septic inspections at property transfer. Virginia's HB 2671 (effective July 2025) and Massachusetts Title 5 mandate inspections statewide. New Jersey requires them in most municipalities, with NJ DEP maintaining a voluntary inspector registry.
Advanced Treatment Units Growing
ATUs and nitrogen-reducing systems now account for 15–20% of new installations. Environmental regulations in coastal and watershed areas are driving adoption.
Labor Shortage in Septic Services
The industry faces a skilled labor shortage as experienced professionals retire. Trade programs are growing but not fast enough to meet demand.
Smart Septic Monitoring
IoT sensors that monitor tank levels, flow rates, and system health are entering the market. Early-stage adoption among regulated properties.
