Hjørring Vandselskab Welcome to Hjørring Water Company

Information about Hjørring Water Company

Hjørring Vandselskab A/S was established in 2007, and the company manages the administration and operation of sewage systems and wastewater treatment plants as well as water distribution systems in Hjørring Municipality. This means that Hjørring Vandselskab 1) handles all wastewater from public sewers in the municipality, 2) is responsible for the collection scheme for those households not connected to public sewers and 3) supplies drinking water to approximately half of the municipality’s citizens or more than 19,500 households, businesses and holiday homes. The remaining citizens and companies are supplied by private waterworks.

Hjørring Vandselskab has five waterworks, two large and two medium-sized wastewater treatment plants in addition to a number of small plants and pumping stations. Our administration is located on Åstrupvej 9 in Hjørring.

The company employs approx. 60 employees of whom just over half work in the field. The rest works with planning, design and administration. The company is 100% owned by the Municipality of Hjørring.

Water consumption
Your family’s water consumption depends on your habits and installations. Consumption levels might vary considerably between two households made up of the same number of people, but as a rule of thumb, ‘normal’ consumption is considered between 40 to 50m3 per person per year. Hence, if you are four people in the household, a ‘normal’ consumption level will be somewhere between 160 to 200m3 of water per year. However, if you wash your car regularly or water your garden extensively during the summer months, consumption will of course be higher.

If you want to see what water costs for you and your family, please check our rates.

Water meter
Hjørring Vandselskab replaces your water meter approx. every nine years. It is a free service for you in order to ensure correct readings and prevent damage to your property. However, you can also keep an eye on your water meter to help avoid damage or excess consumption. Make it a habit to control your water meter at least once a month to check if consumption is normal. In this way, you can ensure that large amounts of water do not damage your property due to leaks, breakages and frost damage. Remember, it is your responsibility to secure your installations!

Prices and payment
We know bills can be difficult to make sense of, so we have made a guide for you. On the same page you can see how often you receive bills from us and what payment options we offer. If you have questions about prices, bills or anything else, you are always welcome to contact us on 38 41 28 28 or

In order to make readings and payments in time and thereby avoid fines and additional costs, we urge you to have a look at the important dates to remember below.

We understand that moving to a new country and getting to know its systems with utility readings and payments can be a challenge. Our bills can be difficult to understand for Danes, never mind when you don’t speak the language and hence members of our customer service department are always at hand to help you if you have any questions to the below. We look forward to working with you.


Around 20th February
We send out your year-end account statement. The statement shows your total consumption of water and cost of wastewater for the past year. We also send you an estimate of your consumption of water and wastewater for the current year. The estimate is split into two instalments (1. and 2. aconto) – payable in March and September. 1st instalment covers the period 1st January to 30th June.


10th March
It is time for you to pay 1st instalment for the current year. Should you have paid too much in the previous year, this amount will be deducted from the 1st instalment. Should you have paid too little, the amount will be added. You can see the total payable amount from our letter sent out in February or by logging into your personal account.


20th August
We send out the bill for the 2nd instalment. It covers your estimated consumption from 1st July to 31st December.


10th September
Deadline for the timely payment of 2nd instalment.


We send out reading cards. Please note the numbers on your water meter on the card and send it to us or log them into your online account. If you log them online yourself, we do not add a charge, but if you wish to post, mail, telephone or deliver the reading personally, we add a small fee of 50 kr. to your account. You must send us your reading by the beginning of January at the latest – the exact date is highlighted on the reading card and posted on FB.

Hjørring Vandselskab supplies clean drinking water to more than 19.500 households, businesses and holiday homes across Hjørring Municipality. Per day, that translates into approx. 10.000.000L that we pump from five waterworks, and the water is led through just under 1.000 km pipes – all the way to your property. Outside your property the installations are our responsibility, but inside your ground they are yours.

We work to deliver the best and cleanest water to you, but in very rare cases the water in the tap may have a slightly different color than normal. Read here why that may be:

Reddish-brown water:
If your water has a reddish-brown color, it will most often be due to deposits of ocher that are stuck in your pipes. It is only stagnant water that will absorb color from ocher, so you will most often experience the discoloration, when your pipes have not been in use for longer periods of time. The discoloration is not dangerous and should disappear if you let the water run for a few minutes.

White water:
If your water is white, it is often caused by a lot of air bubbles in the water. It is a temporary, harmless phenomenon that can occur if air is trapped during repair works on the distribution system. The air will slowly disappear from the water pipes, when water is left running.

Greenish or yellowish water:
If your water is greenish or yellowish, it is a leak in your hot water tank.

The water in the hot water tank originates from the district heating, which adds a green trace material to the hot water in order to easily detect any leakage. District heating is usually a closed system, that is not connected to the drinking water in your tap.

In this case, you should contact a plumber, who can help you correct the problem.

Hjørring Water Company cleans wastewater for approx. 35,000 households in Hjørring Municipality. We have 11 treatment plants, approx. 200 pumping stations and more than 1,100 km of sewers. We clean the wastewater to safeguard the water quality in streams and lakes for the benefit of the environment, people and animals.

Conventional sewage:
Wastewater is the water that comes from the toilet, the bathroom, the kitchen, etc. That is, every time you flush the toilet, take a bath or wash up, you create wastewater.

Wastewater contains – in addition to the natural human waste – chemicals and pollutants. These are difficult for nature to break down, so our wastewater must be thoroughly cleaned first. Therefore, it is important that we constantly optimize our sewage systems and treatment plants.

If you are not on the sewer network, we will empty your septic tank. The scheme is mandatory, and if your property is a permanent residence, we empty your tank once a year; if it is a holiday home, it is once every two years. You pay for the service.

Separate sewerage:
One way we guard you and our society against climate change in the near future is by including sustainable solutions in our construction work today. In the future, heavier rains will put our sewer systems under severe pressure. This means that the current sewer system, where sewage and rainwater run in the same pipe, becomes too small. Therefore, we work to separate rainwater from wastewater and lead either away in separate pipes.

The purpose of separate sewage is to:

  • Safeguard the environment by reducing pollution of streams, lakes and the sea
  • Reduce the risk of water in your basement and on your land
  • Reduce flooding of roads, driveways, etc.

Implementation of separate sewerage is a requirement from the municipality and a necessity because of climate change. Although it initially requires a great deal of work, it also brings with it a number of new opportunities for utilising rainwater. However, as a landowner, before you can reap the benefits you might have to do a part of the work yourself. You can see on our website if there is a separate sewerage in your area. Please see our planned works in your area here.
