Pedda Cheruvu is a giant water tank that fills up after another one at Devarakadra (about 5 km away from Dokur) reaches capacity. Once the former is also filled, water flows to another tank in the chain. It is in this fashion that tanks such as Chakali Koyikunta, Vani Vampu, Badi, and Vampu receive water.
