With even dispersion of greywater or effluent to the land with dripper lines allows for a greater absorption of the volume preventing saturation spots that typically form in gravity feed soakaways. Dripper line system can spread the volume of discharge over a 24-hour period, balancing out the peek waste water flow from dwellings.
Interestingly with the volume of discharge being spread out over a greater period of time this increases the ability of the soil to absorb liquid by preventing it from going dry. A minimum moisture level is needed to be maintained in the soil allowing it to absorb the next volume of discharge without run off or flowing past the dry soil, into deeper more sensitive soils
There are many different land areas and topography of property that can be difficult to have an old fashion soakaway, but with dripper lines there is more possibility to apply the discharge over and around any obstacle from steep to small sections the discharge field designs can fit in to most landscapes.
With conventional gravity fed dispersion fields the application of nutrients found in greywater cannot be applied to the land where it counts. Well-designed gravity fed fields are meant to avoid the thirsty-root structure of trees and plants to prevent root ingression, where as it is opposite with Netafim dripper lines, the dispersion fields can be right in the thick of it feeding the trees and plants directly.
With Dripper Lines, the discharge of greywater is commonly applied to the land to feed vegetation and this allows for increased evaporative functions through the process called “Transpiration” *
Consideration to the effective size of the dispersion fields can be explored where certain pant and tree varieties have a high-water requirement, field sizes can be reduced. Information on this can be found online and from horticulturalist’s.
*Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves
With dripper line systems, it is easy to repair, service and expand-on to the dispersion fields. It is common that the dripper lines are within the first few centimetres of topsoil without the use of scoria this makes the access to the drippers easy and fast to repair. Where the standard of the greywater is cleaned to a high and safe level dripper lines can be used on the surface and relocated if desired.
Netafim is the world leader in dripper line systems providing the largest range of irrigation and wastewater dripper systems
With over 40 years of experience in drip irrigation for demanding agricultural applications, Netafim has also been pioneering innovations in drip irrigation for the landscape industry.
In recent times, we have seen a change in direction for residential irrigation systems. The word 'water-wise' is a common term when we talk gardening and this term describes what a drip system will deliver in a residential application. As blocks get smaller and designers get more creative there is a need for an irrigation system that puts the water exactly where it is needed.
