Borrow pits are the locations from where the embankment soil is obtained. The following guidelines govern the location of borrow pits :
(a) They should be preferably not located in the road land. If unavoidable, they should be located as near to the road boundary as possible.
(b) For a minimum distance of 5 m from the toe of the final embankment, no borrow pits shall be dug. For Rural Roads, this distance may be 1.5 m.
(c) They should be rectangular in shape.
(d) They should not be dug continuously and ridges should be left between borrow pits.
(e) They should be drained so that water does not collect in them and be a breeding ground for mosquitoes.
