Procurement Requirements for Water Efficiency (2010)
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.
How can I ensure my building is efficient?
Effective building design, construction and management can deliver major savings in water use and the associated costs of energy, water supply and wastewater treatment. This can be achieved without compromising the performance and user acceptability of installed products.
A proactive approach to water efficiency (outlined in Figure 1) needs to exert influence over:
- the design specifications applied to new construction (providing the potential); and
- the way in which a building is used, managed and maintained.Through the procurement process, some organisations will have control over both aspects (e.g. owner occupiers or developers who manage the common parts of their properties), while others will only have control of design and construction (e.g. developers) or operations (e.g. property managers). The guidance and model approaches presented here can be applied to each type of organisation.The model procurement wording is available to download at: www.wrap.org.uk/waterefficientprocurement.
