What is this standard about?
BS 8595 gives recommendations on how to select water reuse systems. It covers systems for rainwater harvesting, storm-water harvesting and greywater reuse. This water is used for a variety of non-potable water uses like watering gardens, laundry and flushing toilets.
It does not cover systems supplying potable water for drinking, food preparation and cooking, dishwashing and personal hygiene. Nor does it cover other sources of non-potable water, such as treated effluent, reclaimed industrial process water and water abstracted from wells and boreholes.

Why should you use this standard?
This standard also fits in with the government’s “Future Water” policy to encourage the reuse of water and the utilization of alternative supplies. It will help the UK maintain a world leading position in environmental sustainability.
It also contributes towards the sensible use of water in low carbon and low impact buildings. This matters because some early water reuse systems turned out to be high energy consumers while others have shown that inappropriate technology and management can lead to potential health risks e.g. when WC flushing systems have failed.
