Connecting your home's water network in Luxembourg

Moving to Luxembourg? Once you've found your accommodation, you'll need to make sure that it's connected to the water network. This is not usually a problem, as the communes are responsible for water distribution. However, you'll need to take the necessary steps to register with the commune when you declare your arrival. 

Connection to the water network through your local authority

Connection to the water supply network is the responsibility of the commune where you live.

If you live in a house, as soon as you move in and register as a new citizen of the municipality ("Gemeng"), you must request that your home be connected to the drinking water network. The bill for your consumption will be sent to you regularly by the municipal administration.

If you live in a block of flats, the connection is paid for by the building association. Your consumption will be deducted from your monthly charges.

For Luxembourg City, you need to contact the Water Department or the Bierger Center directly. You can use this opportunity to declare your new residence.

The water supplied to Luxembourg households comes from the Lac de Haute-Sûre in northern Luxembourg. Its quality depends on our actions to preserve it. Preserve Luxembourg's nature by taking part in the Grouss Botz!

How can you reduce your water bill?

Water is a precious resource, even though Luxembourg enjoys a temperate climate with plenty of rainfall.

Luxembourg benefits from an immense reserve of drinking water in the north of the country. The lake at Esch-sur-Sûre supplies Luxembourg households with 50% of water consumption, with the remainder coming from underground reserves. To preserve water reserves, it is advisable to monitor consumption and save water.

Rainwater harvesting

If you live in a house with a garden or an apartment with a terrace, don't hesitate to collect rainwater to water your plants. To do this, you can install a rainwater collection tank fed by your roof gutters. And if you're building a new house, why not install separate water systems inside? This way, you can optimize the use of rainwater and save on the drinking water supplied by your local authority?

Rainwater has many uses. It's excellent for watering plants, washing your car, filling your swimming pool if you have one, or washing floors. If you have an internal rainwater network, you can use it to flush your toilets or wash your clothes.

Reduce water consumption

The average household in Luxembourg consumes 135 liters of drinking water per day, of which only 4% is used for eating and drinking. 36% is used for personal hygiene and 37% for flushing the toilet! In exceptional cases, water consumption can increase by up to 40 m3 per year per inhabitant.

In other words, we can reduce our consumption of drinking water by applying a few simple measures.

The best way to reduce your water consumption and cut your water bills is to monitor and repair water leaks. A dripping tap uses an extra 4 liters of water per hour. A leaky toilet uses up to 25 extra liters of water per hour.

Opt for energy-saving equipment. Double flush toilets save 40% of normal consumption. Water-saving showerheads and flow reducers on taps reduce water consumption by 50%. Household appliances such as dishwashers and washing machines are becoming increasingly economical. Keep an eye on this point when you buy, and don't hesitate to invest in a new washing machine.
