Provides recommendations on how to select water reuse system(s), taking into account water resources, surface water management, water supply and sewage infrastructure.

This British Standard gives recommendations on how to select water reuse system(s), taking into account water resources, surface water management, water supply and sewage infrastructure. It applies to both new and existing developments in residential and non-residential premises.

This British Standard covers the following water reuse systems: rainwater harvesting, stormwater harvesting and greywater reuse. It covers the supply of water for domestic water uses that do not require potable water quality, such as laundry, toilet flushing and garden watering. It does not cover systems supplying potable water for drinking, food preparation and cooking, dishwashing and personal hygiene.

This British Standard does not cover other sources of non-potable water, such as treated effluent, reclaimed industrial process water and water abstracted from wells and boreholes.

NOTE1 Although this British Standard does not give specific recommendations relating to the use of rainwater, stormwater or greywater for fire suppression or commercial irrigation, these applications are not excluded.

It does not cover water butts or direct reuse systems for external use. It also does not cover product design for specific system components or the design and installation of water reuse systems.

NOTE2 Further information on the design and installation of water reuse systems can be found in BS8515, BS8525‑1 and BS8525‑2.
