How we verify every listing
No pay-to-play. A listing publishes when the data proves it's real, licensed, and operating.
Our sources
| Source | What it gives us | Refresh |
|---|---|---|
| Arkansas Dept. of Health onsite wastewater roster | Installer & pumper licenses | Weekly |
| Oklahoma DEQ certified installers & licensed pumpers | Certifications, capabilities | Monthly |
| Missouri DHSS registered installers (state open-data portal) | Registrations, counties served, expirations | Weekly |
| Tennessee TDEC licensed installers & pumpers | Annual state permits | Monthly |
| Public business data | Reviews, hours, operating status | Rolling |
We also publish what the verification runs teach us: fewer than 1 in 7 licensed septic contractors can be found on Google.
The quality score
Every listing gets a 0 to 100 score: active state license, valid phone, live website, public reviews, recent permit activity, and agreement across independent sources. Below 40, a listing stays unpublished. Lapsed licenses and closed businesses are removed automatically, and every listing shows the date it was last verified.
