[[Image:swing basket.jpg|right|250px|Using a swing basket to dump water into an irrigation canal.
The swing basket is made from cheap materials like woven bamboo strips, leather, or iron sheet to which four ropes are attached. Two people hold the basket facing each other, they dip the basket into the surface water and the basket is lifted by swinging it and emptied into an irrigation channel from which point the water flows to the fields. This lifter can be used at depths of up to 1.2 m. Typical flow rates of 60 to 80 l/min are obtained at depths of 0.75 m.
Suitable conditions
| Advantages | Disadvantages |
|---|---|
| - Simple, inexpensive technology which can be locally made and maintained - Easy to operate by both adults and children |
- Limited to lifts of less than 1.2 m - Limited water yield 60-80 l/min suitable for small fields |
