Where treated water returns to the soil
The drainfield is where treated effluent returns to the ground. We install subsurface drip dispersal fields sized to your percolation results and available area — distributing effluent evenly through pressure-dosed tubing, which works on tighter soils and smaller lots than a conventional gravity field.
Sized to your soil
Field area is set by your soil's loading rate (TCEQ Table I) and your home's design flow — no guesswork.
Even pressure dosing
Pressure-dosed drip tubing spreads effluent evenly across the field, protecting the soil and extending its life.
Fits tighter lots
Drip dispersal works where a standard gravity field won't — ideal for smaller or clay-heavy properties.
What a drip dispersal field is
A drip field is a grid of small-diameter tubing buried a short depth in the soil, fed under pressure on a timed cycle from an aerobic treatment unit. Instead of dumping effluent into a gravel trench and letting gravity sort it out, the pump doses a measured amount through emitters spaced across the whole field, so the soil receives water slowly and evenly over a wide area. Chapter 285 treats it as a non-standard dispersal method requiring secondary treatment first, which is why drip is always paired with an aerobic unit and never with a plain septic tank.
When drip is the right call
Drip is the answer where surface application is impractical and a conventional field is not allowed. That usually means one of four things: heavy clay with a very low loading rate, a lot too small or too irregular for a spray area, a wooded or landscaped property where nobody wants sprinkler heads, or ground with enough slope that surface application becomes awkward. Because the field is subsurface, it can also run under a lawn or a garden without taking the area out of use.
How the field size is calculated
There is no guesswork in the number. The required dispersal area is your home's design flow in gallons per day divided by the loading rate the soil evaluation assigns — so a tighter soil class produces a proportionally larger field. Chapter 285 then sets the emitter density for drip at roughly one emitter per four square feet of field (§285.33(d)(3)(D)), which converts that area into a length of tubing. The same math drives the range our instant estimator shows you, which is why the estimate moves when you change bedrooms or square footage.
Living with a drip field
Day to day, a drip field is the least intrusive dispersal method there is: nothing is visible except the control panel and a few access points. The trade-offs are that it depends on the pump and the filters staying healthy, and that it shares the aerobic system's maintenance contract requirement. Keep vehicles and heavy equipment off the field, do not plant deep-rooted trees on top of it, and let the maintenance provider flush the lines on the normal service interval.
Frequently asked questions
Can I have a drip field without an aerobic system?
No. Drip dispersal is a subsurface method that requires secondary treatment ahead of it, so it is always fed by an aerobic treatment unit. A conventional tank alone cannot supply a drip field.
How deep is drip tubing buried?
Shallow — the point of drip is to put treated water into the biologically active upper soil where it is taken up efficiently. The exact depth and cover come out of the system design and the county-approved plan for your lot.
Can I plant grass or a garden over a drip field?
Grass and shallow plantings are fine and actually help the field work. Avoid deep-rooted trees and shrubs over the tubing, and keep vehicles, trailers, and heavy equipment off the area so the lines are not crushed or compacted.
How big will my drip field be?
It is your design flow divided by the soil's loading rate, so it depends on the house and the dirt together. A tight clay lot can need several times the area of a well-draining one for the same house. Our estimator shows the range in about a minute.
Is drip more expensive than spray?
Yes, drip is our higher-priced dispersal option because there is more material and more control equipment in the ground. It buys you a system that fits lots where spray will not work and that stays completely out of sight.
