Title: The Development of a Gravity Fed Micro-irigation System for Trees Shrubs and Vines

We have developed a moisture-powered, self-flushing, polymer valve for the automatic hose-fed irrigation of trees, shrubs and vines that works with turbid water. The valve will operate in remote regions where there is no access to electricity and where conventional micro-irrigation is not viable. This enables commercial and subsistence Dryland farmers to grow more food. Because the irrigation industry was not fulfilling our defined need, for a simple low-energy solution, we engaged with specialists from other sectors. We learnt about new technologies and were able to combine these to produce a new ‘effect’ – a bi-stable polymer valve. See
