Water and waste guide
Grey water is the used water from sinks and showers. It is not the same as toilet waste, but it still needs to be handled responsibly.
Quick answer: always follow campsite rules. Use designated disposal points where required, avoid drains that are not meant for grey water, and never dump waste where it can cause nuisance or pollution.
Common disposal options
- Drive-over motorhome service points.
- Portable waste containers for pitches without drains.
- Drainage kits where site rules and pitch drainage allow.
- Onboard tank emptying at approved disposal areas.
Good habits
Use strainers to reduce food waste entering the tank, choose campsite-friendly cleaning products, rinse tanks periodically and keep hoses stored separately from drinking-water equipment.
