Commercial, industrial and institutional customers can use a significant amount of water in theirdaily operations. Effective water use surveys using simple tools and calculation shortcuts thatshow the economic benefits of a water efficiency measure are most appreciated by the customer.Higher customer awareness can lead to increased participation to implement potentialconservation measures. This paper presents different tools to help measure, calculate and present the economic benefits of water efficiency in many commercial, industrial and institutional applications. The paper includes examples of basic tables that convertwater use from gallons per day into total costs per year, along with a section that provides a spreadsheetfor calculating water savings associated with increasing the cycles of concentration in coolingtowers. A third section provides information on selecting water efficient nozzles and calculatingwater and energy savings for equipment cleaning operations. The final section provides shortcutsto estimate CII water treatment efficiency and calculate water and energy savings for sites thatmust further purify potable water supplies for their own uses. Includes tables.
