DispersalSubsurface Drip
When gravity dispersal is off the table — tight lots, poor soils, high water, nitrogen-sensitive permits — drip puts treated effluent into the root zone in controlled, metered doses. We build the headworks and the panels in house.
Dispersal for the sites nothing else fits
A drainfield needs area, fall and soil. Drip needs much less of all three, because it doesn’t rely on gravity or soil storage — it meters effluent out through emitter tubing in doses the ground can actually take.
- Shallow installation, in the biologically active root zone
- Time-dosed — the field rests between doses instead of flooding
- Follows contours; works on lots a conventional field never could
- Runs behind either plant — AN Series where the permit stacks nitrogen requirements, AP Series where it doesn’t
- Or fully standalone — headworks and field for an existing treatment plant, or a conventional septic that’s run out of drainfield options
The headworks is the heart of the system
Everything that decides whether a drip field lives or dies happens in one assembly: filtration, metering, pressure control and zone switching. We build ours in house — plumbed and wired as a unit, run by a UL 508A listed panel from Legacy Controls — so what goes in the basin is tested, not assembled over a hole.
- Disc filtration ahead of the field — emitters stay open
- Flow meter and pressure gauge, so service visits read numbers, not guesses
- Solenoid zone valves with sealed connectors on our own harnesses
- Field flush and filter backwash plumbed in from day one
- Assembled, pressure-checked and function-tested before dispatch
The whole assembly, in 3D
Drag to spin it, pinch or scroll to zoom. Headworks, pump, valving and basin as one unit — look at it from underneath, from the discharge side, from wherever the question is.

Tap any part of the model — the twenty-one sections defined in the CAD file itself. Tapping one lights it up; hover or tap a name below to highlight it and fly the camera there. On a phone or tablet, tap the AR icon to stand the assembly on the floor at full size — useful for checking access and clearances before you dig. Ask us for dimensioned drawings.
Single zone or multi-zone, the panel runs it
Drip is a scheduling problem — dose, rest, rotate, flush. The panel does the arithmetic. Ours are built by Legacy Controls to UL 508A, configured for the zone count and dosing regime of the actual field.
- Timed dosing with rest periods per zone
- Automatic zone rotation on multi-zone fields
- Scheduled field flush and filter backwash cycles
- High-water alarm, pump protection and run indication

Daily flow, available area, soils and the seasonal high water. We’ll come back with zone count, headworks spec, pump selection and a price. New construction or retrofit: this headworks or one of our other models, paired with an AN or AP Series plant — or standalone behind the treatment you already have.
