US-EPA Guideline
The United States Environmental Protection Agency released a new document, titled Safeguarding Against Natural Hazards and Extreme Weather Events: A Resource Guide for Onsite Wastewater Treatment Systems.
Onsite wastewater treatment systems (OWTS), also referred to as septic systems or decentralized systems, treat wastewater and return the treated effluent to the environment. Due to natural hazards and extreme weather, wastewater treatment systems, including centralized systems and OWTS, may become impaired and require greater oversight or more frequent infrastructure adjustments to ensure proper performance.
