You Need a Permit Before Installing a Septic System in Rains County
Texas calls septic systems on-site sewage facilities, or OSSFs. In Rains County, the county Environmental Office handles the local packet.
Before work starts, the packet asks for the fee, application, site check, technical sheet, and system design. A site evaluator, sanitarian, or engineer must do the site and soil check.
The county reviews the plans. If it approves them, it gives approval to start work. The system must be inspected before it is covered. After a good inspection, the county issues the notice of approval.
