What the counts do and do not mean
RIDEM licenses the people who design onsite wastewater systems and the soil evaluators who assess whether a site can take one. It licenses installers too, but publishes a list only for designers and soil evaluators — so this covers who you need before the digging, not who does it.
The number against each county is how many licensed businesses give that county as their address — not how many will travel to it. A Rhode Island licence is granted by RIDEM and is valid across the state, so a company two counties away can legally do the work. In a rural county the listed handful is rarely the real choice set, which is why every county page here also lists its neighbours.
Designer and soil evaluator licences expire 31 December and are renewed with continuing education. Every listing here shows its expiry date, and expired licences are left out entirely.
The licence types in this table
- Designers — a business licensed for the work that designs onsite wastewater treatment systems.
- Soil evaluators — a business licensed for the work that performs the soil evaluations that decide what system a site can take.
