Nearly one in four households in the U.S. depends on an individual septic system or small community cluster system to treat its wastewater. EPA has recently revamped its septic website to better serve homeowners, state and local officials, industry professionals, and its partner organizations. The website includes a suite of new case studies demonstrating what communities across the country are doing to effectively manage their decentralized wastewater infrastructure and find solutions to meet their own unique wastewater infrastructure needs.
