As you may already know, the topography in Meghalaya is hilly, with steep slopes and rough landscapes. Hence, using ground channels in this area is unfavorable. So, bamboo drip irrigation is widely preferred.
Usually, water sources are distant from plantation sites and so the main bamboo channel runs several meters, sometimes even a couple of kilometres. Water is thus obtained and managed through a brilliant bamboo system of secondary and tertiary channels to reach each part and corners of the plantation.
Bamboo channels are utilized to tap perennial water from up-slopes, which is cleverly diverted to the lower parts using gravity. An ingenious system that wastes very little water and works to this day.
Channel sections are made of bamboos of different diameters, to control the water flow in such a way that the water reaches the site in the lower reaches, where it is circulated without spillage. The channels are supported by forked branches.
It is so perfected that about 18-20 litres of water entering the bamboo pipe system per minute gets transported over several hundred metres and finally gets reduced to 20-80 drops per minute at the site of the plant.
One must see it to appreciate the intricacy and the smartness of the system. It is estimated that even up to 20 liters of water flows into the channel every minute.
