Around 3,707 tonnes (4086 tons U.S.) of weeds have been cleared from the 910-acre Bellandur lake. In the past five days alone 737 tonnes (812 tons U.S.) have been removed by just two machines, according to an official release issued by the Bangalore Development Authority.
The BDA is said to be using three weed harvesters — one long boomer and two floating excavators — which were introduced on the lake only on June 2, 2017. While one weed harvester cleared 340 tonnes from May 29 to June 2, the second one cleared 410 tonnes.
