Water supply companies in Switzerland

Like other home utilities in Switzerland, water is controlled by government-supported companies at a local level. Water in Switzerland is extremely high-quality and most tap water comes from natural alpine springs or rivers fed by snowmelt. Here’s what you need to know about water supply in Switzerland, and how to set up with your local supplier. 

How to set up your water supply in Switzerland

Water supply in Switzerland is standardised at a local level, meaning you cannot choose your own provider. Instead, you need to register for an account with the supplier that covers your area (see below). 

Typically, you only need to do this if you have bought a house. If you are renting in Switzerland, your landlord will normally handle matters with the water supplier, and the cost of any water you use will be covered by your monthly rent. Your rental contract will specify the exact situation. 

If you do need to sign up with your local water company, the process is quick and easy. Simply contact your local provider and provide some details such as your name and address, and a meter reading from the day you moved in. You’ll also need to provide the details of your bank account so that your bills can be paid by direct debit. If you can provide the name of the previous occupant, that can ensure the changeover process is as smooth as possible. 

Water suppliers in Switzerland

Water supply in Switzerland is controlled by the cantons, who typically delegate responsibility to the municipalities or private companies. This means the system is highly localised. There are approximately 2.400 independent water suppliers across the country, according to the Swiss Gas and Water Industry Association (SVGW). 

While there are considerable variations in how water supply systems are implemented across the country, all suppliers are bound by the same obligations when it comes to quantity, quality and pressure. 

To find your local water supplier and their contact details, you can use the address search tool at trinkwasser.ch. 

Paying your water bill

If you are renting in Switzerland, you will most likely not pay a regular water bill, as the cost will be included in your rent, but check with your landlord to be sure. 

Otherwise, the easiest way to pay your water bill is as a regular direct debit. When you sign up, you provide your bank details and consent to have your payments automatically collected. This is typically on a quarterly basis. 

Once per year, your supplier will then issue a bill that compares your estimated usage with your actual usage, based on a meter reading. If you have used more or less than expected, you might be asked to pay more, or receive a refund. 

If your local water supplier also manages your electricity or gas, or your municipal taxes, you can sometimes pay your water bill together as one payment with these other costs. 

Can I change my water supplier?

In Switzerland, you can only get your water from your local water company. You are unable to get water from another water company unless you change address and your new home is covered by a different supplier. 

Can you drink tap water in Switzerland?

Tap water in Switzerland is extremely high quality. Indeed, thanks to the country’s mountainous location, around 40% of Switzerland’s water comes from alpine springs and is so clean that it doesn’t need to be treated at all before going into the general supply. The remaining 60 percent of water is sourced from a mixture of groundwater and surface water. 

The Federal Food Safety and Veterinary Office (FSVO) regularly assesses water quality to ensure it meets comprehensive standards. 

You can drink the water from any tap in Switzerland. You can also drink from all fountains in Switzerland, unless directly stated otherwise.
