Swimming pool where we don’t use any chlorine for filtration. We got spring water at just 3 mtr depth of which we have decided to make pool. Same water when get full start to overflow in our well and used for plantation with sprinkles system. All work done manually so that to take machine for digging purposes we don’t have to cut down the trees. We are trying to give natural swimming pool so that it will so healthy that people don’t have to swim in chlorine water.
