Provides reimbursement for enhanced septic system projects

This bill creates a state fund to reimburse property owners and installers for enhanced septic system projects. It defines "enhanced" systems as those reducing nitrogen to 19 mg/l or significantly cutting phosphorus/PFAS pollution in wastewater. Reimbursement covers 75% of costs (up to $25,000 per property) for enhanced systems versus 50% (up to $10,000) for standard systems. The program applies only to projects with county participation agreements after the bill’s effective date. The bill was signed into law on July 23, 2025 (Chapter 188).
