Wastewater Management

Cesspools & Septic Systems

Forty percent of Rhode Islanders get their drinking water from groundwater or small local reservoirs. Outdated cesspools and failing septic systems are a major source of pollution to these water supplies. What you flush down the toilet directly affects the water you drink and the waters you fish, swim and boat in.
