Indigenous bamboo drippers
In Meghalay, bamboo channels have been used efficiently to carry water
from mountainous springs and water courses for the last 200 years. About
18 to 20 litres of water is carried up to 100 m for irrigating plants. Water is
so perfectly distributed through these bamboo channels that it applies 20 to
80 drops per minute to each plant. This shows that an excellent indigenous
irrigation system exists in this area.
