Till about thirty years back, the areas around our home and offices used to be unpaved and the rain falling on these areas would percolate into the soil and remain there for being drawn through shallow open wells. With the proliferation of flat complexes, not only have these areas been paved and percolation of rainwater into the soil almost totally stopped,the quantity of water drawn from the soil below has increased manifold. Consequently open wells and not-so-deep bore wells started drying up. The reason is that no sincere attempt is made to replenish the ground water table with rainwater during the monsoon season.
As individuals, groups and communities, let us all wake u before it is too late and not only understand what rainwater harvesting is all about but also implement measures to harvest rainwater is our houses and flat complexes and put it into the soil for our subsequent use.
JPHCL has taken a decision to implement Rain Water Harvesting in all its ongoing constructions steps have been taken to collect the water falling on the roofs and areas surrounding the buildings and use them to recharge the existing wells, aquifers etc.
In an average 40´X 60′ roof top built up area with an average rainfall of 130 ” during the year will give 700 ltrs. of water per day through out the year which will be sufficient for a family of 5 members. The cost involved is from Rs.3,000/- (single floor) to Rs.30,000/- (for a multi storey), which could be recovered within three years.
