What Is RIWIS?

RIWIS is a statewide, web-accessed database used to organize local information about onsite systems and cesspools, including their location and condition, inspection results, and maintenance. It is easy to use and virtually free ($100 annual fee) for Rhode Island municipalities. RIWIS is a valuable tool, adaptable to any level of wastewater management.

RIWIS is free for service providers, maintained by Carmody™, paid for by industry sponsors, and supported by the University of Rhode Island and RI Department of Environmental Management.

The list of Rhode Island towns enrolled with RIWIS is growing quickly. As of Spring 2008, it includes: Block Island, Charlestown, Foster, Glocester, Hopkinton, Jamestown, Little Compton, North Kingstown, Portsmouth, Scituate, Tiverton.
