Septic Tank Vulnerability Study

What was this study?

Wastewater infrastructure in low lying coastal communities face multiple threats such as sea level rise, storm surge, increased flooding and precipitation, and rising groundwater levels. The purpose of this study was to assess the vulnerability of onsite treatment and disposal systems (aka OSTDS, septic systems) to three potential sea level rise scenarios and potential storm surge. Results of this study identified 2,938 residential septic systems in the city's utility area.
