The International Development Enterprise (IDE) of the USA has also designed and tested a bucket system. The IDE bucket drip irrigation system consists of a bucket, a valve, a filter, an end cap and a 10-m long 12-mm diameter lateral line fitted with 26 micro-tubes, 13 on each side. All the pipes are pre-fitted and packed in a small box. The 13 micro-tube connections are spread over the length of the drip lateral at a spacing of 0.75 cm. Water from the bucket flows out like a small stream from all 26 micro-tubes and spreads out in a circular pattern. Four plants are planted in each of the circles and therefore a total of 104 plants can be watered by the IDE bucket system. The valve is used for flow regulation—giving the advantage that the bucket can be filled beforehand and irrigation started when required. The end cap is used to close the end of the lateral line.
