Septic Permits in Collin County

Collin County Engineering Department - Development Services opens in a new tab

The Texas Commission on Environmental Quality writes the rules for on-site sewage facilities, which is the state's term for a septic system. It is not usually the office that issues the permit. That job is delegated to a local authorized agent, and in Texas an authorized agent is not always a county.

Every company on record in Collin County

Ordered by verification score. The score counts records rather than workmanship, and the license line says which of three things is true: verified against the roster, checked and not found on it, or not yet checked at all.

The license check in Texas

Texas publishes a roster we can check a company against, and we have checked 19 of the 19 companies in Collin County against it. 5 matched by name and number. 14 did not appear, which is a finding rather than an accusation: a trading name that differs from the licensed name will not match, and a company can tell us the licensed name and have it corrected.
