Fresh Water Tank
Clean water tank, drinking water tank, onboard water supply, fresh tank, water reservoir
A fresh water tank is the fixed tank in a motorhome or caravan that stores potable water for drinking, cooking, and washing, filled at campsites, service points, or fresh water taps.
Fresh water tanks range from 20L to 200L depending on vehicle size. Drain and dry the tank when not in use to prevent bacterial growth. Some van lifers use portable jerry cans instead of fixed tanks for flexibility.
FAQ
Where can I fill a motorhome's fresh water tank on the road?
At campsite service points, municipal aires and Stellplätze (€0–2 per fill), motorhome service points (Flot Bleu network in France), and motorway rest areas. In rural areas, a public drinking fountain or approved spring works for short stays. Apps Park4Night and Campercontact flag points with a water fill icon.
How do I sanitise a fresh water tank?
Use a food-safe sanitiser: dilute Milton Sterilising Fluid (1:100) or a dedicated product like AquaClear. Fill the tank, run it through all taps, leave 30 minutes, then flush thoroughly with clean water. Do this at the start of each season and after any long storage period.
