Translate the following English sentence to French:
"And, finally, I want to say that I think that the tighter arrangements which are being introduced in regard to payment schemes and pricing are quite proper if we, as consumers, are to be given an incentive to use water resources efficiently and, at the same time, obtain arrangements which can promote the achievement of those environmental goals about which, I believe, there is broad agreement."
Enfin, je déclarerai que j'approuve les mesures prévues en vue de renforcer les modalités de paiement et l'établissement des prix, car elles inciteront les consommateurs à utiliser plus efficacement les ressources en eau, et le règlement contribuera à atteindre les objectifs environnementaux à propos desquels - je pense - s'est dessiné un vaste consensus.
