I am somewhat confused with what you have advised and would request for some clarity. If the pond is being made so that run off is prevented, then I am assuming that the pond will have a bottom which is directly the earth to allow the water to slowly percolate. In which case, won’t the pond water be over in a couple of months after the monsoons?
If the pond has an impervious layer, like a liner or something, to collect the water, then it will act as a storage facility. In which case the question of water percolating will not arise, and the purpose of recharging the ground water using this system will not happen.
So it’s either a storage facility or a system to collect and recharge the ground water. But it can’t be both.
Is this thinking correct?
