Artificial Recharge Storm Water Management In Hero Honda Motors Ltd For Haridwar Dharuhera Plants, Haryana State, India

摘要

Artificial recharge is the process by which rainwater is infiltered into groundwater system and ground water resources are augmented by altering natural conditions of replenishment. The storm water generated in industries with large catchment can be diverted to scientifically designed artificial recharge system based on runoff generated at peak rainfall intensity and recharge rate of sub-surface strata. There are several methods for artificial recharge depending upon the feasibility in different regions. In case of higher infiltration capacity of vadose & saturated zone, percolation pits with recharge shaft in the reservoir can be planned for increased surface water storage assimilation in to the aquifer. This serves as significant tool in storm water management and improvement of ground water regime through artificial recharge reservoir. Similarly, for recharging deep aquifer, injection wells can be planned through filtration chamber (2). Hero Honda Motors had been facing problem due to storm water generation within the plant premises at Dharuhera, Haryana and Haridwar, Uttranchal due to improper drainage system & absence of any artificial recharge measure. The detailed studies were carried out by M/s GWMICC P Ltd., Jaipur in both the plants regarding the existing drainage system, hydrogeological conditions, climatic conditions & scope of implementation of recharge measures. An outcome of these studies, recommendations were given for drain design, new rainwater harvesting structures & artificial reservoirs. As a follow up, the Hero Honda Motors Ltd. had sincerely implemented the recommendations through M/s Jain Earth Matters, Jaipur for proper storm water management in their premises. After implementations, in last two rainy seasons, all the structures are working efficiently even at more than average rainfall of last five years and the problem due to storm water within the premises is completely solved.
