Sweden has plenty of places to empty a motorhome, but they don’t all take the same waste. The detail most guides skip is that rest areas take cassettes and nothing else. This page covers which stop takes what, how to empty correctly, and why the ground is never an option.

When you need this

  • Your cassette indicator is on red and you’re between campsites.
  • Your motorhome has a fixed black-water tank rather than a cassette.
  • Your grey tank is full after a night at a rest area.
  • You need fresh water and aren’t sure a tap is drinkable.
  • You’re touring in autumn or winter, or through Norrland, where stations are far apart.

Which stop takes what

A motorhome produces black water (svartvatten, toilet waste, in a cassette or a fixed tank), grey water (gråvatten, from sink and shower), and needs fresh water. All three are handled at a disposal point, called a tömningsstation or latrintömning.

Nobody is obliged to provide these stations. Motorhome and boat waste falls outside Sweden’s Water Services Act and the municipal waste duty. So coverage depends on who chose to build one. Some municipalities run free stations, often at a harbour ställplats or a treatment plant. Others have none. Campsites and ställplatser fill most of the gaps.

Rest areas: cassettes only

This is the detail that catches people out. Trafikverket, the Swedish Transport Administration, runs about 270 rest areas, and only some have a latrine point. Trafikverket says those points are for cassettes alone (lösa latriner). Fixed tanks need a larger campsite or a fuel station that offers it. And grey water can’t be emptied at rest areas at all. It mustn’t go into storm drains or be mixed with latrine waste.

Trafikverket’s traffic-information map shows which rest areas have which facilities. The stay limit at rest areas is 24 hours.

Campsites: ask if you’re not staying

Staying guests normally empty and fill as part of their stay. Some campsites let passing motorhomes use the station for a fee, sometimes only at set times of day. Ask at reception rather than driving straight to the station.

How to empty and fill: step by step

  1. Find a station before you need one. Use a ställplats app, the campsite list or Trafikverket’s map, and check the season.
  2. Match the station to your tank. Cassette: any latrine point, rest areas included. Fixed tank: a larger campsite or a fuel station that offers it. Grey water: a campsite, ställplats or municipal station, never a rest area.
  3. Read the sign. Stations may list accepted toilet chemicals, opening hours or a fee for non-guests.
  4. Empty the cassette into the chute and rinse it with the rinse tap provided. Keep that tap and its hose away from your fresh-water filler.
  5. Empty grey water into the drain marked for it at the station. A gutter grating outside the station area is a storm drain, not a disposal point.
  6. Fill fresh water from a drinking-water tap. A tap marked ej dricksvatten is not drinking water.
  7. Leave it clean. Rinse spills into the drain and take your rubbish with you.

The law: why never in nature

No Swedish statute mentions motorhome cassettes by name. It doesn’t need to. The Environmental Code (Miljöbalken) defines waste water, avloppsvatten, to include any liquid impurity. It requires waste water to be led away and treated so that it harms neither health nor the environment (chapter 9, sections 2 and 7).

Toilet waste and grey water from a vehicle fit that definition. Emptying either onto the ground, into a lake or into a storm drain does the opposite of what the law requires. “It’s only dishwater” is no defence: grey water is waste water too.

Dumping outdoors can also fall under the littering ban. Littering where the public has access or can see is punishable by a fine, or up to one year in prison in serious cases.

Freshness note: Chapter 15 of the Environmental Code was restructured on 1 July 2026. The littering ban that older sources cite as 15 kap. 26 § is now 15 kap. 39 §. The penalties, in chapter 29, are unchanged.

There’s also a practical cost. Visible dumping by motorhomes is exactly what turns municipalities against overnight parking, so one careless driver costs everyone a stopover.

Toilet chemicals

There’s no national list of permitted toilet chemicals. Each station sets its own terms, so read the sign.

The distinction that matters is between two kinds of fluid:

  • Blue fluids based on formaldehyde or strong biocides can kill the bacteria that small treatment plants and septic tanks depend on. A station connected to a small plant may refuse them.
  • Green, formaldehyde-free fluids are accepted more widely, which makes them the easier choice on a long trip.

Some products are marketed as so biological that you can empty them anywhere. That doesn’t change the law. The duty to treat waste water applies to the waste, whatever fluid is in it. Avoid household cleaners in the cassette too; stick to toilet fluid the station accepts.

Fresh water

Campsites, ställplatser and combined municipal stations usually have a drinking-water tap. Swedish municipal water is regulated as a foodstuff and is safe to drink, so you can fill with confidence; see tap water in Sweden.

Two habits keep it that way. Only fill from a tap meant for drinking water, never one signed ej dricksvatten. And carry a dedicated hose for fresh water, never using the cassette rinse tap.

Winter and the north

Service points follow the season. Many water points shut in autumn to stop them freezing, and some latrine stations close too. Norrköping’s harbour latrine stations for boats, for example, close from about October to April. A station an app lists in July may be locked in October.

In Norrland and the mountains, the gaps between stations are long all year. A few habits make the difference:

  • Empty whenever you pass a working station, not when the indicator turns red.
  • Carry a spare cassette on northern and off-season routes. It doubles your range.
  • Fill fresh water at every opportunity.
  • In winter, protect your own tanks and pipes from freezing, and verify every station by app, sign or phone before you drive to it.

FAQ

Where can I empty my motorhome toilet in Sweden?

At a disposal point (tömningsstation or latrintömning). Campsites, ställplatser, many municipal stations and some fuel stations have them, and some of Trafikverket’s rest areas have a cassette-only point. Stations are voluntary, so coverage varies by municipality. Find the next one before the indicator turns red, especially in the north and outside summer.

Can I empty grey water on the ground in Sweden?

No. Grey water counts as waste water under the Environmental Code, which requires it to be led away and treated so it harms neither health nor the environment. Pouring it onto the ground, into a lake or into a storm drain breaks that duty. Hold it until you reach a station that takes grey water, such as a campsite or municipal station.

Can I empty my motorhome at a Swedish rest area?

Only a toilet cassette, and only where the rest area has a latrine point. Trafikverket says these points are for cassettes alone: fixed black tanks need a larger campsite or a fuel station that offers it, and grey water cannot be emptied at rest areas at all. The traffic-information map shows which rest areas have facilities.

Can I use a campsite’s dump station if I’m not staying there?

Often, but not always free. Guests normally empty and fill as part of their stay. Some campsites let passing motorhomes use the station for a fee, sometimes only at set times of day. Ask at reception first rather than driving straight to the station. Municipal stations, where they exist, are often free for everyone.

Which toilet chemicals can I use in Sweden?

No national list exists; each station sets its own terms, so read the sign. Blue fluids based on formaldehyde or strong biocides can kill the bacteria that small treatment plants and septic tanks rely on, so formaldehyde-free (green) fluids are accepted more widely. Whatever fluid you use, the waste still goes only into a station.

Where can I fill fresh water for my motorhome?

At the same stations: campsites, ställplatser and combined municipal stations usually have a drinking-water tap. Swedish municipal water is regulated as a foodstuff and safe to drink. A tap marked ej dricksvatten is not drinking water. Use a separate hose for fresh water, never the cassette rinse tap.

Are motorhome service points open in winter in Sweden?

Some, not all. Many water points shut to prevent freezing, and some latrine stations close for the season; Norrköping’s harbour latrine stations for boats, for example, close from about October to April. Check each station’s opening months by app, sign or phone before relying on it, and carry a spare cassette on a winter route.
