EPA is joining state and local partners to launch SepticSmart Week 2023, a week-long annual campaign to educate homeowners and renters on how to properly maintain their septic systems. When septic systems are well-functioning, the health of the nation's communities and ecosystems is better protected. By being SepticSmart, homeowners can also avoid thousands of dollars in unnecessary repairs. Running from September 18 through September 22 this year, SepticSmart week is a partnership between EPA, state, Tribal, and local officials, wastewater professionals, and homeowners.
