St. Xavier's College in Mapusa is organising a workshop on 'rainwater harvesting' at the college hall on March 8, 2003 at 2.30 pm. It is being conducted by Director of Chennai's Rain Centre Sekhar Raghavan. You're invited!
About two-thirds of the earth's surface is covered by water. Not incidentally, the human body consists of about 60% water: for many invertebrates and plants the water content is much higher. About 94% of water is found in the oceans, almost 5.9779% is located underground whereas rivers, lakes, soil mosture and atmospheric vapour, which constitute the major source of drinking water account for 0.0221% of the total volume.
It is estimated that 48 countries will face water shortages by the end of 2025. Including India. Due to the enormous growth of population and the pollution of water, freshwater has become scarce. Even rainwater will not fill this gap, because 90% of the water from rainfall will run through to rivers and oceans.
No proper planning is done to store this water and make it available for use in the future. Merely storing of this water in dams, reservoirs, ponds will not increase the water level in the ground.
All efforts should be made to see that water will seep into the ground and thus increase the ground water level.
Keeping this in consideration, the RAIN CENTRE at Chennai has taken up the work of harvesting rainwater for domestic use, and the excess water thus available will be allowed to seep into the ground to increase the groundwater level.
The features of the Rain Centre at Chennai include: a model for rooftop harvesting, surface run-off harvesting and poster panels on case studies, live RWH models and screening of RWH films.
The Rain Centre has installed rainwater harvesting in Tamil Nadu Government buildings, public sector units, colleges and in individual residential buildings.
Do come to hear all about it at Xavier's on Saturday.
