Frequently asked questions about Greywater Recycling

What is greywater?

Greywater is wastewater from baths, showers, washbasins, and washing machines. It does not include water from toilets (blackwater) or kitchen sinks (which contain fats and food waste). Treated greywater can be reused for toilet flushing and garden irrigation.

What standard covers greywater systems?

BS EN 16941-2:2021 (On-site non-potable water systems - treated greywater) is the current standard for the design, installation, and maintenance of greywater systems; it superseded the withdrawn BS 8525-1:2010. The Water Supply (Water Fittings) Regulations also apply to prevent backflow into the mains supply.
