The Irrigation and Flood Control Department of the Delhi government has engaged four firms to assist its officials in the exercise.
A senior department official said the move is intended to know exact topography and hydrography of water bodies, river and drains and also the construction activities in their vicinity.
"After the survey, a comprehensive plan will be made to revive water bodies across the national capital," the official said.
Last year, Chief Minister Arvind Kejriwal had asked the then water minister Kapil Mishra to prepare a blueprint to revive the water bodies.
"All the executive engineers have been asked to execute the work of topographic and hydrographic survey of water bodies, drains, rivers and all other construction activities through these four empanelled firms," he added.
