Drip Dispersal Percolation SystemsDrip Dispersal Percolation Systems are sometimes called drip irrigation or drip fields.
Subsurface drip dispersal is an efficient method for dispersal of wastewater into the soil and is ideal for soils with low permeability. It is a precise method for applying wastewater effluent over an infiltration surface in small volume doses throughout the day. The uniformity of the dosing and equal distribution can be designed and operated to provide for unsaturated flow over the entire infiltration area. Final disposal is mostly through infiltration to the ground but disposal through evotranspiration can take place during the growing season of the year.
The unique feature of drip dispersal networks is the use of uniformly spaced drip emitters that are inserted within flexible tubing to control the rate of wastewater discharges out the tubing through small orifices. Typically, the dripperline is installed directly into the soil without aggregate or other media using suitable machinery this can be achieved without the need for re-lawning. Pumps are used to fill and pressurize the dripperline sufficiently to achieve uniformity of distribution.
Advantages of Drip Dispersal Systems
- Ideal for sites with low permeability
- Subsurface so no loss of ground to mounds or percolation areas
- Suitable for sites with elevation and slope issues
- No mess or big machinery necessary for handling large quantities of stone etc., as required for conventional systems.
