Drinking water for motorhomes: where to fill your tank?

Where can you find drinking water for a motorhome?

To fill a motorhome drinking-water tank, look for a service area, campsite or distribution point whose operator allows filling. Check that the water is labelled as suitable for drinking, that the tap is intended for filling and that the service works. A water symbol on a map or an accessible tap does not confirm all three.

This guide covers choosing a filling point and preparing your equipment. To find toilets and other facilities for your stop, see our general guide to finding water, showers and wastewater disposal.

Service area, campsite or public tap: what should you check?

At a service area, distinguish the filling tap from the tap used to rinse a toilet cassette. Read the signs and the service unit instructions. Some facilities require a token, a card or payment. Parking and water may have different conditions: free parking does not mean that water is also free.

At a campsite, ask whether you can fill up without staying overnight. For a public fountain or tap, check drinking-water information and local rules on collecting water. Other travellers using it does not replace permission from the operator. During restrictions or seasonal closures, choose another authorised point.

Our guide to service areas, motorhome parking and campsites explains the differences before you make a detour.

Your checklist before connecting a hose

Read the drinking-water information, permitted uses and service unit instructions.
Identify the filling tap; do not use a tap reserved for rinsing toilets.
Prepare a hose or container suitable for drinking water, with compatible connections.
Check that the equipment is clean; keep hose ends off the ground and away from wastewater facilities.
Check the tank level and vehicle limits: the water you carry adds weight.
Close the tank and store filling equipment separately from toilet and wastewater equipment.

Use the vehicle and equipment manuals for connections, maintenance and tank use. Do not improvise cleaning or treatment product doses from general advice: follow the manufacturer’s instructions and use a product suitable for the intended purpose.

Clear water, drinking water and stored water are different questions

Clear or odourless water is not proof that it is safe to drink. The World Health Organization explains the risks of contaminated drinking water. A spring, stream or fountain without reliable information should therefore not be treated as a monitored drinking-water supply.

Water quality at the distribution point does not resolve the question of the vehicle’s tank. The condition of the tank, hose and containers, and the storage conditions, also matter. Follow the manufacturer’s maintenance recommendations. If you doubt whether water is suitable for drinking or cooking, use another safe drinking-water source and seek appropriate advice.

The French Ministry of Health’s information on tap water and water quality checks explains the general framework. It does not individually certify a tap you find while travelling.

Plan a refill without unnecessary detours

Before leaving, estimate your needs from actual use: the number of travellers, cooking, washing up and equipment. There is no universal quantity or storage period suitable for every vehicle. On a first campervan weekend, observing consumption helps you plan future trips.

In VanSpot Finder, check the services near a spot and their distances (in French). Open the chosen water point’s listing, then check opening times and conditions with the operator if needed. Keep a second option on the route: a short distance does not guarantee suitable vehicle access or a working tap.

Plan for the used water too. Finding a suitable grey-water or toilet-cassette disposal point at the same time avoids waiting until your tanks are full.

Frequently asked questions

Do all taps at a service area provide drinking water?

No. A tap may be intended for rinsing a toilet cassette or another purpose. Check the signs and use only an authorised filling point with confirmed drinking-water quality.

Can I fill my tank at a campsite without staying overnight?

It depends on the campsite. Ask the operator whether this service is offered to passing travellers and what conditions apply.

Is water from a fountain always safe to drink?

No. A fountain and clear-looking water do not guarantee that it is drinkable. Check reliable information and the conditions of use; if in doubt, choose another safe source.

How much water should I carry in a campervan?

The amount depends on the travellers, intended use and vehicle. Assess actual consumption, respect weight limits and plan where you can refill.
