Caravan Grey Water Disposal Guide
Quick answer: Caravan grey water should be collected, stored briefly and emptied at approved disposal points. Bad smells usually come from food residue, warm storage, dirty containers or sink waste pipes. A good routine uses regular emptying, rinsing, sensible sink habits and suitable grey water treatment where label instructions support that use.

What is grey water?
Grey water is used water from sinks, showers and washing up. It is different from toilet waste. In caravans and campervans it is often collected in a portable grey water container. Motorhomes and RVs may have onboard grey tanks.

Where to empty grey water
Use campsite or motorhome service point disposal areas. Do not empty grey water onto pitches, roadsides, drains or wild areas unless local rules clearly allow it.
Containers and storage
Choose a grey water container that is easy to move when full, has secure caps and fits your storage space. Empty it regularly rather than waiting until it smells.
Odour control
Reduce food residue entering the sink, rinse containers, empty often and use suitable grey water treatment according to label instructions. Warm weather makes odours worse.
