Standard designs for adoption of roof top rainwater harvesting in Delhi

In order to increase the natural ground water resource rain water harvesting and artificial recharge to ground water has become increasingly important in ground water management. The subsurface geology, post monsoon depth to water level and declining ground water level conditions of the State indicate that the area is suitable for artificial recharge. The favorable aquifer zones down to depth of ground water level which is lying unsaturated presently may be suitable recharged through rain water harvesting. For the convenience of general public standard designs of Rainwater Harvesting have been prepared.
