CEE 3306 09/04/08 HW #1 1. Demand, when applied to water, refers to the amount of water needed to serve a community.

Dry states withdraw more water from the public supply than wet states in order to make up for the lack precipitation they receive. 2.

Meterage – Metering water consumption lowers the per capita water consumption because when water is metered the people feel a sense of responsibility to conserve water and fix leaks. 4. System management – Well managed systems have lower per capital consumption because leaks are monitored and repaired in a timely manner.
