Drawing: [http://www.samsamwater.com/library.php?serie=RELMA%20Technical%20Handbook%20Series RELMA.]]]__NOTOC__ <small-title />This is a variation of the [[Chapin]] bucket kit and involves using a drum of about 200-litre capacity or the equivalent of five bucket drip irrigation systems. The development of this adaptation is credited to a farmer in Eldoret in the Rift Valley Province of Kenya who, after working with the bucket drip kits, connected an old drum to supply four drip lines. KARI improved on the drum adaptation by designing the manifold with 4 or 5 openings each serving two drip lines.
This is '''Uses of a drum system'''<br> A drum system covering 5 beds each 1 m wide and 15 m long can be used to grow 250 plants (tomato, egg plant and similar plants requiring a variation spacing of 60 cm along the [[Chapin]] bucket kit plant rows); 500 plants (spinach, cabbage, kale, pepper and involves using similar plants requiring a drum spacing of about 200-litre capacity 30 cm along the plant rows); or the equivalent 1,500 plants (onion, carrot and similar plants requiring a spacing of five bucket drip irrigation systems10 cm). The development of this adaptation is credited drum system also offers water storage and control through a control valve, making it possible to a farmer in Eldoret in fill the drum for irrigating at another time. Six examples are presented: the Rift Valley Province of KARI drum system from Kenya who, after working with the bucket drip kitsWaggon Wheel system from South Africa, the Family, Plastro and Micro-Tal systems from Israel, and the IDE drum used in India. ===Construction, connected an old operations and maintenance===The standard drum kit system comprises a drum to supply four , control valve, a manifold and drip lines. KARI improved on The drum should be filled with the valve in the closed position. To irrigate it is important to open the valve fully. This allows the drum adaptation by designing water to be distributed quickly through themanifold with 4 or 5 openings each serving two drip linesand allows for good water distribution.

# Finally, connect one end of the connector tubing to the filter plug and insert the barb fitting to the other end. Connect the drip tube to the drip lock fitting.
===Costs===
To install a drum system costs about KSh7,500 (US$100) in Kenya.
