A bill for an act relating to the treatment of private sewage disposal systems, including monitoring, maintenance, and reporting requirements, and including applicability provisions.

This bill requires owners of private sewage systems (serving up to four homes or 16 people) to hire certified technicians for ongoing maintenance and inspections, with annual checks for Class A systems (media-based filters like peat moss) and biannual checks for Class B systems (mechanical systems). It mandates that all inspections be reported to county sanitarians, who will compile results into a public database (excluding personal details). Systems must follow manufacturer specifications, and Class A systems are preferred over Class B for most sites due to lower maintenance needs. The law applies to systems installed after July 1, 2026.
