Pond construction by manual labour has been stopped. Earth work is undertaken by bulldozers and tractors. Bulldozers are used in the case of large scale excavations whereas tractors are used for the projects requiring the earth work not more than 200 ha generally. However, finishing work will be done by using the tractors for the purpose of perfect slope for pond bottom and bunds.
