International Development Enterprises of Colorado, USA, designed and tested a drum kit system which can irrigate 520 vegetable plants. The drum kit consists of 130 pipes (1-mm diameter) called micro-tubes, fitted to 5 rows of 12-mm diameter PE laterals. Water from the drum flows out in a small stream from all 130 micro-tubes. The water then spreads out in a circular pattern to about 0.5-m radius. Four plants are planted in each of the circles.

==Suitable conditions==
Field tests are reported to have been carried out on vegetables in the hill areas of Nepal and in Andhra Pradesh, India.

==Construction, operations and maintenance==

'''System components'''<br>
* 200-litre drum
* Tap
* Line filter
* 16 mm submain pipe
* 5 x 10 m PE laterals (12-mm diameter) fitted with 26 micro-tubes (1-mm diameter)
* 5 end caps.

'''Assembly instructions'''<br>

# Prepare the area to be irrigated.
# Mount the drum.
# Connect laterals to a 200-litre drum of water by a 16 mm-diameter pipe (submain).
# Unroll all the pipes, lay them on the ground and connect to the drum. A manual is provided with the kit as a pictorial guide to correct installation and planting.
