The primary purpose of drip irrigation systems is to maximise the value of water delivered to the fields by ensuring that it is targeted at the root zone of crop plants, without excessive loss.
Water is delivered to the crop using a network of branching pipes, with emission points spaced along their lengths. Each point supplies a measured, precisely controlled uniform metered amount of water directly to the roots of the crop.
This method is hugely efficient compared to the previous method of flooding the field naturally, resulting in the loss of valuable water and the growth of unwanted weeds.
Take a look at the videos on this page that show a number of drip irrigation systems at work in our project villages.
