Greene Eden - Tota


Both water shortage and quality are major factors increasingly affecting turf irrigation in Australia. Since new water supplies are unlikely to be developed (or may increase water costs) people responsible for irrigated open spaces must improve management of water use, seeking improved methods and products which will facilitate this.

Sub-surface drip irrigation, as the name suggests, is an irrigation system installed below the soil surface, within the general proximity of the plant’s root zone and will maximize water use efficiency, significantly reduce soil surface evaporation, and maintain constant soil moisture levels. By placing water directly at the root zone via a consistent schedule, without disadvantaging the plant growth or yield, sub-surface drip irrigation is gaining momentum and acceptance from Schools, Local Governments, developers and managers of sports facilities.

As sub-surface drip irrigation is NOT just another irrigation method and little, to nothing, was known in Australia, Greene Eden invested both time and resources in the research and development of this irrigation method in order to provide a high quality, efficient, cost effective alternative to traditional pop-up sprinklers.

The only obvious comparison between a traditional pop-up sprinkler system, and sub-surface drip irrigation is that they are completely different, and the problem has arisen during the past sixteen years, that clients frequently endeavor to compare the two.

Some advantages of a sub-surface drip system are:

  • Reduced water consumption (perhaps as high as 50% depending on prior watering practices). There is no evaporation, wind-deflection, run-off or overspray.
  • No vandalism or system damage as there are no surface components;
  • Hazard-free for grounds-users;
  • Ideal for treated effluent/wastewater. It is totally accepted by EPA/Health Commission;
  • Irrigation scheduling can occur even when the grounds are in use;

A pop-up sprinkler system meets none of these criteria.

Testing of soil (and sometimes water) on the site is an important pre-requisite as sub-surface drip systems are reliant on the ability of the soil to move the moisture through capillary action.
