The legislative authority of a municipal corporation may take possession of any land obtained for the construction or extension of water works, reservoirs, or the laying down of pipe, and also any water rights or easements connected with the use of water. Any land, water right, or easement so taken possession of for water-works purposes shall not be used for any other purpose, except by authority of the director of public service and with consent of such legislative authority.
