FAQ's

Q.

What is Sub-Surface Textile Irrigation?

A.

A Sub-surface irrigation method where water is supplied to the soil from the surface of a geotextile fabric rather than from individual emitters in a drip line. Dispersing the water over a larger area reduces the rate of water discharge to the soil bringing it closer to the capillary absorption rate and also converts the drip line from a series of point sources to a single, broad line source.

Q.

How does the KISSS Below Flow product range water the soil?

A.

Water flows through the KISSS geotextile layer and is taken up by the soil at its natural absorption rate.

Q.

What are the benefits of KISSS sub-surface irrigation systems?

A.

KISSS has a number of benefits:

  • KISSS uses up to 60% less water than traditional irrigation
  • Salinity management  
  • Reduced water tunneling     
  • Precise root zone management (moisture, air and nutrients)
  • Reduced fertiliser costs
  • Chemical free inhibition of roots
  • Significant maintenance savings (less damage as it is sub- surface)
  • Reduce labour (fixed, automatic irrigation requiring no movement of pipes)
  • Surface remains dry while roots are irrigated
  • Reduced evaporation, surface runoff, deep drainage and wind drift
  • Reduced plant disease and weed growth
  • Safe use of waste/ grey/ recycled water (Link to ‘IWT Overview)
  • Vandalism is reduced due to sub-surface installation
  • Safer usage of recycled or grey water
  • Reduced water bills

Q.

How is KISSS different to conventional sub-surface drip irrigation systems?

A.

Conventional subsurface drip irrigation (SDI) systems discharge water to the soil from regularly spaced emitters along a drip line. Each emitter acts as a point source of water and so the drip line gives rise to a series of circular wetting patterns. Conventional sub-surface irrigation systems must be run long enough to wet the driest region of soil.

KISSS' patented design disperses water evenly by matching the capillary action of the soil, creating a controlled and uniform wetting pattern. The KISSS irrigation system saves water by directing water straight to the root zone and matching soil absorption rates.

Q.

What do I have to do to maintain my KISSS irrigation system?

A.

Maintenance is simple and will ensure the effectiveness of your KISSS irrigation system. To optimise performance, the KISSS filter should be cleaned and lines flushed every 6-12 months. Timer batteries will need to be replaced as necessary.

Q.

Will roots get into my KISSS product?

A.

Research and practical experience strongly suggests that the unique arrangement of materials in KISSS Below Flow Flat acts as a powerful, non-chemical deterrent to roots entering and blocking emitters.

This is consistent with root development studies conducted by Commonwealth and Scientific Industrial Research Organisation (CSIRO) (Muirhead et al., 1998) and with University of Western Sydney (UWS) (Fuentes et al., 2004) trials. Furthermore, in over 10 years of commercial use, there have been no confirmed cases of roots blocking emitters where KISSS has been correctly installed.

Q.

Does the KISSS system experience blockages?

A.

A filter on the KISSS system prevents internal emitters from blocking. An "Air/Vacuum Release Valve" prevents suck back from drainage and discharges air from the system at start up to prevent air locks and to ensure even watering.

Q.

How long will KISSS products last?

A.

KISSS irrigation products are manufactured with polyester and polyethylene. The durable materials will last for many years if routine maintenance is conducted.

Q.

Can KISSS irrigation systems be repaired?

A.

Yes. Should damage occur, the section can be replaced and joiners put in

Q.

Where can I purchase it from?

A.

KISSS can be ordered through your local Toro dealer or irrigation supplier.  If you do not have a local dealer, you can email Irrigation & Water Technologies (IWT) or call 1300 761 781.

Q.

Are you sure that my plants will get enough water?

A.

YES! KISSS irrigation has been proven in domestic, commercial and agriculture applications for many years. KISSS ensures water penetrates deeply into the soil, but remember, low application rates require a longer watering time.

Q.

Why are KISSS-lines available in different colours?

A.

KISSS product lines are available in two basic colours:

BLUE: for general irrigation using a potable water source

PURPLE/LILAC: is used in accordance with international and local standards and indicate reclaimed or treated water supplies. The colour coding ensures that its non-potable water supply is instantly recognisable.
