Notwithstanding anything in this Order or in any Act wholly or partly incorporated herewith, the Council may, instead of acquiring any land that they are authorised to acquire compulsorily under this Order, purchase and acquire compulsorily such servitudes or rights over or in any such lands as they may require for the purpose of constructing and using or removing the works or for the purpose of obtaining access to the works, by creating as well as purchasing such servitudes or other rights already in existence, without the Council being obliged or compelled to purchase any greater interest in, under or over the same, and the provisions of the Lands Clauses Acts shall extend and apply to such servitudes and rights as if the same were lands within the meaning of those Acts.
