The KISSS system works by pulsing water through sub-surface lateral irrigation lines to a geo-textile fabric which,using its own capillary action, disperses water into the soilat or below the root zone.Introduction6mabass 6.

KISSS SSDIKISSS design disperses waterevenly by matching the capillaryaction of the soil, creating acontrolled and uniform wettingpattern.Each emitter acts as a pointsource of water and so the dripline gives rise to a series ofcircular wetting patternssaves water by directing waterstraight to the root zone andmatching soil absorption rates.must be run long enough to wetthe driest region of soil.http://www.kisss.com.au/UsefulInfo/FAQs.aspxIntroduction11mabass 11. http://www.droughtsolutions.com.au/residential_%20irrigation.htmKISSS SSDIntroduction12mabass 12.

The Aims of the Thesis1. Compare the yield rate between surface dripirrigation, sub surface drip irrigation (SDI) andKappilary Sub Surface Irrigation System(KISSS).2. Study the amount of water applied by eachsystem.3.
