70 licensed septic contractors based in Kent County. Every license number below is sourced from public licensing records, with a link to look it up yourself.
Grouped by the county of the address on each license record, which can be a mailing address, so it doesn't tell you where the business works. When the record names no county, we place it by ZIP code, then town.
Checked against Rhode Island Dept. of Environmental Management (RIDEM). Roster copy last refreshed 2026-10-03.
All 6 towns named on the license records based here, with the number of listings in each, most first.
Each class as the issuing agency prints it on the license record. A record that names more than one class counts once under each, so the rows can add up to more than 70.

Listings based in Kent County whose license class covers each service. Cost ranges are national; each links its cost guide.
None of the listings based in Kent County hold a license class we can match to septic tank pumping, septic inspection, septic system design or perc test and soil evaluation. Ask any contractor whether they do this work, or try a nearby city.
Septic (onsite wastewater) contractors handle everything from routine septic tank pumping and cleaning to repairs, inspections, and new system installation. States license each role separately (a pumper is not necessarily licensed to install, and vice versa), so match the license class to the job.
Before you sign anything: confirm the license on this page is still active with the agency that issued it, ask for proof of insurance, and get at least three written quotes; pricing on this work varies widely by site conditions.
