Should water be for the people or the politicial lobbyists?

A petition is being prepared to take fto the EU calling for it to uphold the right to water. This is laudable, but the sub clause demanding that the 'liberalisation' of water and sewerage should be outlawed is not. Indeed, it is an illiberal demand, since it is saying that only one model of water management ought to be allowed irrespective of the merits of other forms of service provision. So, the question is; should the provision of water and sewage services be for all by all means necessary or should they be to the satisfaction of one political lobby irrespective of practical merits?
