Before you hire anyone
The registry answers “who is licensed?”. These answer the questions that come immediately after it.
How to verify a septic contractor's licence
The records tell you who was licensed on the day they were published. Here is how to check whether that is still true today.
How often should a septic tank be pumped?
Every three to five years is the default. There is a measurable rule that beats it, and a pumper is already taking the measurement.
Signs a septic system is failing
Slow drains, standing water, a green stripe across the lawn. What each one means, which are urgent, and who to call for what.
Buying a house with a septic system
The file exists before you close, and it answers questions an inspection cannot. What to ask for and which office holds it.

What this registry is, and is not
Every state licenses septic work and publishes who holds the licence. Almost none of them publish it in a form you can actually use. Some of it is three-column PDFs. Some of it is licence files with no phone numbers in them at all. One state sells its list rather than publishing it.
This site republishes those records as pages you can navigate. Every company page names the document it came from and the date that document was published, so you can check it yourself. We do not license anyone, we do not rank anyone, and no company can pay to appear, disappear or move up.
