Delta County, Texas publishes onsite-wastewater records through unknown. Records can be searched without an account.
A permit file usually holds the as-built drawing: tank location and capacity, drainfield layout and size, the soil evaluation, the system type, and the approval date. Almost every septic job starts by finding that drawing.
A pumper needs the lid location and tank capacity. Without the as-built, locating a buried lid is guesswork billed by the hour. Pumping interval is driven by tank size and household size, both on the drawing. A tank pumped too rarely pushes solids into the drainfield, and a ruined drainfield is the expensive failure, not the tank.
A design starts from four inputs, and three of them are usually already sitting in the county record for a developed lot:
Repair and replacement designs work the same way but start from the recorded as-built, because the existing tank, field footprint and any reserve area constrain what can be built.
Commercial and multi-family systems are the same logic scaled: design flow comes from a fixture or use-type table rather than bedrooms, tanks get larger with traffic-rated lids, grease interception is added for food service, and a licensed engineer typically stamps the drawing.
Installation normally requires a permit issued before work starts, an inspection while the system is still open, and a final as-built submitted on completion. That final drawing is the document that ends up in the county file, which is why records exist at all.
Most lenders, and many counties at point of sale, require an inspection. Inspectors start from the recorded as-built: without it they are probing blind, and time-of-transfer inspections are commonly where a failing system is discovered. Buyers should pull the file before closing, not after.
A repair designer needs the original system type, the soil evaluation and the existing layout. Where the original drainfield area is known, a replacement area is often already reserved on the drawing.
Pools, sheds, driveways, fences and heavy vehicles over a drainfield destroy it. Root intrusion does the same slowly. The setbacks and the field footprint are on the drawing, which is the cheapest possible way to avoid the most expensive failure.
Costs vary by soil, system type and local code, so we do not publish a price for this county. What the record does tell you is the system type and drainfield size, which is what any contractor needs before quoting rather than guessing.
Whatever the job, the recorded file is the cheapest first step:
Designing a system here is free to try. We build a code-referenced septic design from the parcel itself: design flow from bedroom count, tank sizing, soil-driven drainfield area, dispersal method and setbacks, rendered as a drawing you can take to a county reviewer. Where a recorded as-built exists we start from it rather than from assumptions. Generating and viewing a design costs nothing.

Yes. You can generate and view a code-referenced septic design for a parcel at no cost: design flow from bedroom count, tank sizing, soil-driven drainfield area, dispersal method and setbacks. Where a recorded as-built exists for the property we start from it rather than from assumptions.
Design flow comes from the bedroom count under almost every state code, not square footage. That flow sets tank capacity, and the soil evaluation (percolation rate or soil profile, depth to water table and to any restrictive layer) sets the application rate and therefore the drainfield area.
A soil and site evaluation, the design flow from bedroom count, the setbacks required to wells, property lines, surface water and foundations, and a reserve area for future replacement. On a lot with an existing permit, the original soil work is often already in the county record.
It depends on tank capacity and how many people use it, both of which are recorded on the system's as-built drawing. Pumping too rarely sends solids into the drainfield, which is the expensive failure. Pull the drawing to get your actual tank size rather than guessing.
The as-built drawing filed with the county when the system was approved shows the tank location, the lid, and the drainfield footprint. That drawing is what a pumper or inspector needs, and locating a lid without it is billed as labor.
In almost all US counties yes: a permit before work starts, an inspection while the system is open, and a final as-built submitted at completion. That final drawing is what ends up in the county record.
No. Pools, sheds, driveways, fences and heavy vehicles over a drainfield destroy it, and the required setbacks are shown on the as-built drawing.
The tank location and capacity, the drainfield layout and size, the soil evaluation, and the approval date. It is the document a pumper, inspector or designer needs to work on the system.
