Coia Sanitation Llc

Coia Sanitation is a septic tank and cesspool-cleaning business that Bobby Coia began in 1978, according to a pbn.com article. The company's own website says it was established in Cumberland, R.I., that his son Steven has taken over all operations, and that Bobby and Steven's son Skyler work alongside Steven. The site describes commercial and residential septic work and names a service area that runs from Providence, Pawtucket and Woonsocket to Attleboro and North Attleboro. On Google, a 2026 customer wrote that Steve and his dad have done work at their grandparents' property. A 2026 customer called it a father and son family business and recommended it. A 2025 customer said scheduling was easy and that the company was always on time, polite and personable.
