Digging distribution channels and feeder drains

11. The distribution channels carry the water to all parts of the field. They branch off the main irrigation channel. The feeder drains take away the water from the rice field, and carry the water into the main drain.


The distribution channels carry the water to all parts of the field

12. All the channels should be quite straight.

The earth dug out in making the channels is used to build the levees.
Pack the earth down firmly on the levees so that you can walk on them.
The channels divide the whole field into small fields which are called plots.
The channels should not be wider apart than 20 metres.
