This document includes an overview of the benefits of incorporating water efficiency measures in building design, specifications (flow rates etc) for water-efficient products and guidance on how facility managers can maintain and improve performance. This guidance is for those involved in: design and construction of new buildings; or management and refurbishment of existing buildings. It deals with reducing water use of “domestic-type” water fittings and appliances (i.e. toilets, taps, etc) by specifying target rates of consumption, and it provides model wording to use in your procurement documents. The wording can be copied or adapted as appropriate.
