Invented by Israel in the 1960s, drip irrigation technology has spread rapidly ever since. Drip irrigation is among the widely preferred irrigation methods in the drier regions of farming in Australia. This efficient method of irrigation offers 90% or even higher efficiency unlike, sprinkler systems which are usually around 80-85% water use efficiency or flood and furrow that is around 60-70% efficient.

Known for its water and nutrient-saving properties, drip irrigation is an efficient micro-watering system. Made of a network of valves, drip lines, or dripperlines, pipes, and emitters, this system is installed on top of or under the soil. The emitters are placed evenly along the pipe and are designed to release water in a drip or trickle directly to the plant base, irrigating the root zone rather than the soil.

The drip irrigation system comprises several components including a pump or pressurized water source, a filtration system, a backwash controller, a pressure control valve, distribution lines, valves (pressure, air release, and isolation), drip lines, or poly tube and emitters, poly fittings, and accessories.

When water is pumped directly from the water supply, it travels through the primary filtration system, and removes any fine particles that could block the emitters or drip lines. Here, you can add a chemical injection fertilizer system. Now, the water is pumped into the field through a secondary filter and different valves to the drip line laterals and emitters.

There are several reasons that make drip irrigation one of the most efficient and environmentally sustainable irrigation methods.

Statistics show that “the global drip irrigation market size was valued at USD 4.63 billion in 2018 and is projected to reach USB 9.37 billion by 2026, exhibiting a CAGR of 9.30%”.

Starting from field crops like maize, soybean or sugarcane, to vegetables, vineyards, tree crops, and greenhouse crops, drip irrigation can be used for any crop. Be it growing in soil or a soil less platform, flat field or on sloping terrain, drip irrigation suits all topographies. Drip irrigation is also perfect for domestic use and is used under lawns, flower beds, in vertical gardens, and pot plants.

The final piece in the drip irrigation system is the emitter or ‘dripper’. These are either welded inside the drip line during the extrusion process or they come as individual pieces that can be attached directly to a lateral pipe as needed. There are several variations and features including pressure-compensating or non-pressure compensating, anti-siphon, anti-drain, extra root resistance, and more. Each dripper discharges water at a very uniform flow rate under a specific range of pressures.
