There are many water saving opportunities available to consumers, industry and governments. Generally, three groups of actions are important - physical measures, economic measures and social measures. Physical measures refer to alterations that can be made to water using equipment or processes. Industrial examples include the installation of water recycling equipment such as cooling towers, and process changes that lower water use. Economic measures refer to means of altering the ways in which users pay for the right to use water.
Social measures refer to broad social policies and actions designed to lower water usage.
Examples include revisions to plumbing codes, legal restrictions on water use during drought periods and campaigns to inform the public about the importance of water. For example, use of water saving shower heads can not only save the homeowner the cost of the water itself but also save in water heating costs. Furthermore, conservation retrofitting of an existing building could generate benefits ranging between 15 and 20 times the costs incurred presently. Finally, water conservation lessens the demands made on a vital natural resource, thereby contributing to the sustainability of Florida's environment.
