Results from the first part of a five-year £6m project to extend metering suggest that water use drops by up to 20 per cent when people know that they are paying for every drop.
Jersey Water has already installed 2,000 of the planned 17,500 new meters that will go into homes by 2015, mainly in the north of the Island.
Jersey Water managing director and engineer Howard Snowden said that the more consumption could be reduced, the longer expensive projects like the extension of the Val de la Mare reservoir could be delayed.
