Which water company serves your home? Start with your city
Identify a likely supplier, then confirm the individual address
Your water company is determined by the property location. Use the city lookup for an initial match and follow the official address check to confirm the home, especially near supply boundaries. Once you know the supplier, its profile brings together registration, moving, meter-reading and billing guidance.
Check the address before you arrange the account
Use the matched supplier as your starting point, then follow the official address check. If the city is absent or the result is uncertain, go directly to the national supplier finder.

How it works
From your city to a confirmed supplier in three steps
- 1
Type your city or town
Search by city or municipality name, or tap one of the popular cities. Accents and capitals do not matter.
- 2
See the likely supplier
We show the drinking-water company whose service area covers that city, with its province and the official pages you will need next.
- 3
Confirm the exact address
Open the supplier's own address check with your postcode and house number before you register, report a move or pay anything.

What the result means
How the supplier finder reaches its answer
The finder works at city level. For each of the 356 Dutch cities in our directory, we compare the city's reference point with the official service areas that the RIVM publishes for the drinking-water companies, and we only show a supplier when exactly one company covers that point. That makes the result a reliable starting point for most homes in the city, but not a guarantee for an individual address, which is why every result hands over to the supplier's own address check.
- 1
One point per city
Each city is matched at its reference point against the supplier boundaries. When several companies meet near that point, we leave the city out instead of guessing.
- 2
The supplier confirms the address
Only the water company can confirm that it supplies a specific postcode and house number. Its address check is the final word before you register or report a move.
- 3
Provinces are not supply areas
Supply areas follow old network boundaries, not provinces. Several provinces are split between two or three companies, so never assign a supplier from the province alone.
5 provinces are split between suppliers
In these provinces, cities are matched to more than one water company. Addresses near the line between two supply areas deserve an extra check.
Numbers show how many city guides each supplier serves in that province.

Official confirmation
Every supplier's own address check
The fastest way to be certain is the supplier's own address or postcode check. Below you find all Dutch drinking-water companies with a direct link to that check, ordered by the number of cities they serve. If you have no idea where to start, the national map from Vewin, the association of Dutch drinking-water companies, finds the company for any address in the country.

Look twice
When the city result needs a second check
For most rentals the city result and the supplier's address check agree. These are the situations where they can differ, or where the supplier is not the one you deal with at all because the building or the landlord sits between you and the water company. Spot them early and you avoid registering with the wrong company or opening an account that the landlord already holds.
Addresses near a supply boundary
Villages and outer districts close to a neighbouring supply area can be served by the other company. Always run the address check for edge-of-town homes.
New-build districts
New neighbourhoods are sometimes connected by a different company than the older town centre. The developer or landlord usually knows which supplier connected the street.
Apartment buildings with a main meter
Some buildings have one meter for everyone and the owner or housing association divides the costs. You then deal with the landlord, not the supplier.
Water included in the rent
Rooms, student housing and furnished rentals often include water. Knowing the supplier is still useful for outages and quality questions.
Shared houses
Only one person can hold the account for an address. Agree who registers and how the advances and the final settlement are shared.
Your town is not listed
Small villages are listed under their municipality. Search the municipality name or use the national Vewin map with your full address.
Finder FAQ
Questions about finding your water supplier
How the city-level lookup works, why we send you to the supplier's own address check, and what to do when your town is missing, sits on a provincial border or has water arranged through the landlord.
How does Luntero know which company supplies my city?
We compare each city's reference point with the official service areas of the drinking-water companies published by the RIVM, based on Vewin data. A city only gets a supplier when exactly one company covers that point. That is why the result is a strong indication for the city, and why you should still confirm your full address with the supplier.
Can I look up my supplier by postcode?
Luntero does not look up individual postcodes. Every supplier offers its own address or postcode check, and the national Vewin map works for any Dutch address. Use our city result to find the right company quickly, then confirm your postcode and house number on its website.
Does every city in a province have the same water company?
No. Supply areas do not follow provincial borders, and several provinces are split between two or three companies. Utrecht, South Holland and North Brabant are examples where neighbouring towns can have different suppliers, so check the address rather than the province.
Can I switch to a cheaper water supplier?
No. Each address in the Netherlands is supplied by the company responsible for that area, and drinking water is not sold on an open market like energy. Tariffs differ between companies, but you pay the tariff of the company that serves your home.
My town is not in the finder. What should I do?
The finder covers 356 Dutch cities and towns, and smaller villages fall under their municipality. Search for the municipality name, or use the national Vewin map or the address check of the company that supplies the surrounding area.
Do I need to know my supplier if the landlord arranges water?
You will not register yourself, but knowing the supplier helps when there is an outage, a question about water quality or a service-charge statement to check. The landlord can tell you which company supplies the building and how the costs are divided.
Keep going with the water guides
Each water guide answers one practical question. Use the supplier finder when you do not yet know which company serves the address, the moving checklist for key-day readings and the switch between two homes, the bills guide to read advances, settlements and separate local taxes, and the city guides for a local starting point in your new town.
Understand the water bill
Fixed charges, usage, advance payments and the annual settlement, plus the municipal and water-board taxes that arrive separately.
