Question: are cesspools legal in ri?
Answer: OWTS Cesspool Phaseout. ... The Rhode Island Cesspool Act of 2007 (RIGL § 23-19.15), as amended in 2015, mandates that all cesspools within the state must, over time, be removed from service. The structure served by the cesspool must either be upgraded to a new OWTS or connected to a sewer line if one is available.
