Robert Coia established Coia Sanitation Service in 1978. To this day it still remains a family owned and operated business. We operate late model vacuum trucks that insure the most efficient and sanitary method of pumping and cleaning cesspools and septic tanks.

There was a strong need for Septic Tank cleaning companies during that time, especially in the Towns of Cumberland and Lincoln. Although there have been a lot of sewers installed since then, there's still a large amount of Commercial and Residential properties that use cesspools and septic tanks. New septic tanks are still being installed, especially in rural areas where there are not sewers available.

We do our best to inform property owners how cesspools and septic tanks function and advise them on how to keep them working properly. Preventive maintenance can almost always prevent problems from cesspools and septic tanks that are designed and installed properly.

We have written a brochure called "What every Homeowner should know about their Septic tank or Cesspool" to help inform them how to care for their systems.

We service Northern Rhode Island and nearby Attleboro and North Attleboro, Massachusetts.  We operate late model vacuum trucks equipped with the most up to date technology and odor reducing equipment available.  Every call is answered by a twenty four hour answering service and is electronically dispatched and promptly returned during regular business hours.  We are fully insured and licensed for the entire State of Rhode Island and for each individual city and town that we service in Massachusetts..

Our Service Area includes Northern Rhode Island and nearby Massachusetts. Please see our service area page for a complete listing of our service areas.
