Rainwater harvesting cost in Nabarangapur
That buys a filter on the downpipe and a recharge pit with a 60 ft recharge bore, which sends about 1,31,325 litres of Nabarangapur's rain back into the ground every year. The bore is the biggest cost, so the final price depends on how deep the water-bearing layer is under your plot; most groundwater monitoring wells in Nabarangapur read 5–10 m below ground.
