The renowned Sorabora Wewa, the massive irrigation reservoir of ancient Bimthanne lies about 1km from the Mahiyangana town. It’s thought to have been constructed during the reign of King Dutugemunu (161–137 BC), legend says that the reservoir was built by a villager and a rather unknown army general called Bulatha, is a place of historical engineering genius. When building of the Sorabora Wewa didn’t place any sluice gate at the embankment but used a strategically located natural rock away from the embankment and cut a deep canal which acted as the sluice for the tank. Since the rock wasn’t subject to erosion by the pressure of water, the ancient builders had decided to do it with the tried and tested Bisokotuwa or valve pit for this creation. It is said that this is the only such type sluice gate found in Sri Lanka.
