Save water

Water efficiency is reducing water wastage by measuring the amount of water required for a particular purpose and the amount of water used or delivered.[1] Water efficiency differs from water conservation in that it focuses on reducing waste, not restricting use.[2] Solutions for water efficiency focus not only on reducing the amount of potable water used, but also on reducing the use of non-potable water where appropriate (i.e. flushing toilet, watering landscape, etc.).[3] It also emphasises the influence consumers can have in water efficiency by making small behavioural changes to reduce water wastage and by choosing more water efficient products.

The Capitol Power Plant made dramatic performance improvements in the generation and delivery of chilled water and steam throughout our facilities. By revitalizing the refrigeration plant and installing new chillers, the CPP increased chilled water efficiency with new chillers that are 20 percent more efficient. These chillers aren't small—one can use more electricity than the Rayburn House Office Building or Hart Senate Office Building on the busiest day of the year. Examples of water efficient steps includes fixing leaking taps, taking showers rather than baths, installing displacements devices inside toilet cisterns, males using urinals rather than toilet stalls, and using dishwashers and washing machines with full loads. These are things that fall under the definition of water efficiency, as their purpose is to obtain the desired result or level of service with the least necessary water.[1]
