Dump Stations, Fresh Water Refills, and Propane in the USA

Dump Stations, Fresh Water Refills, and Propane in the USA

For international travellers, managing waste, water, and gas is one of the most unfamiliar parts of an American RV or campervan holiday. In the USA, these services are generally structured and regulated at state and local level, and they can work differently from many European countries. You cannot empty waste or refill water just anywhere, and propane rules are specific to North America. Understanding where to stop, what to connect, and what is allowed will save time and help you avoid fines or awkward situations at campgrounds.

This guide explains how RV dump stations usually work in the USA, where to find fresh drinking water, and how propane refills often differ from Europe. It focuses on real-world logistics you will deal with on the road, whether you are staying in a large RV park, a public campground, or camping without hookups.

Understanding RV Dump Stations in the USA

An RV dump station is a designated place where you empty wastewater from your vehicle. In US terminology, this usually refers to both:

Black water: toilet waste
Grey water: water from sinks and showers

Dumping waste anywhere else (for example, into storm drains or toilets) is generally illegal and subject to local or state penalties. Enforcement and rules can vary by location, but approved dump stations are always the correct option.

Where to find RV dump stations in the USA

You can typically find dump stations at:

RV parks and private campgrounds
State parks (public campgrounds run by individual states)
Some truck stops and travel centres (large fuel stations designed for long-distance travel)
Some motorway rest areas, more commonly in western states and rural areas

Availability, access hours, and fees vary by state and by operator. Some stations are free for overnight guests, while others charge a small fee if you are not staying there. Seasonal closures are also common in colder regions.

How to use a dump station (basic process)

Park with your waste outlet aligned to the dump inlet
Wear gloves (sometimes provided, but bringing your own is recommended)
Empty black water first, then grey water (to help rinse the hose)
Rinse the hose using only the provided non-drinking water tap

Always keep sewer hoses and fresh water hoses separate, and never use a drinking-water hose for rinsing waste equipment. Take your time: queues can occur, and correct, hygienic use is expected.

Fresh Water Refills: What Is Safe to Drink?

Fresh water refill points are clearly marked as potable (safe to drink) or non-potable (not safe to drink). Only potable water connections should be used to fill your RV’s fresh water tank.

Common places to refill fresh water

RV parks with full hookups (water, electricity, and sewer at your site)
Campground service areas or utility points
Some fuel stations or travel centres, where signage allows RV filling

Never connect a fresh water hose to a dump station rinse tap unless it is clearly labelled as potable. Many sites use backflow-prevention devices and colour-coded taps to reduce cross-contamination.

Units and measurements

In the USA, water tanks are measured in gallons. One US gallon is about 3.8 litres. Distances on road signs and maps are measured in miles rather than kilometres, which is useful to remember when planning refill stops.

Propane in American RVs

In the USA, propane (also called LPG in Europe) is commonly used for cooking, heating, and sometimes refrigeration.

How propane refills usually work

Many US RVs have a fixed onboard propane tank, although some smaller vehicles use removable cylinders
You refill the tank at dedicated propane service points where available
For safety reasons, staff normally connect, fill, and disconnect the hose for you

This differs from much of Europe, where gas bottles are often swapped. In the USA, you typically refill the same tank. Filling rules and access can vary by state and by supplier.

Where to find propane

Large fuel stations and travel centres
RV parks, service centres, and dealerships
Hardware, garden, and farm supply stores

Propane is sold by volume (gallons), not by weight. Tanks are designed to stop filling automatically at a safe level. Some locations may restrict refills if the tank or fittings do not meet local inspection requirements.

Campground Terminology You Will See

Full hookups: water, electricity, and sewer at your campsite
Partial hookups: usually water and electricity only
Boondocking: camping without hookups, often on public land, where self-sufficiency is required
State park: a public campground managed by a US state

Planning Your Route and Stops

In cities such as Denver or Phoenix, dump stations, potable water, and propane are generally easy to find. In remote areas, plan refills in advance, as distances are long and services can be widely spaced.

If you are unsure what utilities are included with your rental or campsite, see the utilities FAQ for clarification.

Final Tips for International RV Travellers

Use only approved RV dump stations and follow posted instructions
Always confirm water is marked as potable before filling
Refill propane before it runs low, especially in cold, rural, or seasonal areas

Once you understand these systems, managing your RV in the USA becomes routine. When you are ready, check current RV and campervan availability through USARVRentals.com to start planning your route.
