I agree with LP. Individual meters are better. Fairer and more environmentally friendly. Our townhouses were built with individual meters but for many years the OC paid a single water bill for the whole site. Eventually it was resolved at a general meeting to be billed individually. Part of what convinced people was that a small number of units were found to have been consuming very much more than the average. It was annoying to those who had been making effort to conserve water to learn they were subsidising profligate use by others.
