This study describes the present system of rainwater collection and storage
facilities, the socio-cultural and economic aspects of rainwater use.
During the months of October to November, 1587, a three--week case study on
rainwater use was conducted in Dacope, Khulna, a coastal region of Bangladesh.
Since the area is located very close to the Say of Bengal, both ground and surface
water contain undesirable level of salinity. Drinking water was an acute problem
in the area. Normally, people of Dacope use water from pond, canal/ditch, river,
tubewell or rainwater, depending on the availability. The study reveals the fact
that a large number of people of the area has been drinking rainwater. People
drink rainwater in the rainy season. But in the off-season they hardly drink rainwater
because of lack of proper storage facilities. Roof discharge was a common method
of rainwater collection. Gutters made of G.I. sheet, bamboo, betel nut tree and
bark of banana tree had been used widely for rainwater collection. People store
rain water in large earthen vessel. They periodically maintain the quality of
stored rainwater using burnt snail shell.
The survey also indicated that about 75% of rainwater consumers preferred to
have large storage facility although most of them could not afford it. Cost of
rainwater collection was found to be Tk 0.29 per litre, which was the lowest among
all water sources. An appropriate rainwater, storage facility may solve drinking
water problem in the area.
