Help and contact

When you move into a property, we issue an account opening bill. This includes only the part of the annual fee covering the period between the date of moving in and 31 December of the current year. 

The first bill for actual consumption will be issued at the time of the annual meter reading. In the meantime, you will receive quarterly instalment bills.

Anyone who has difficulty paying their water bill: 

• Who lives in Wallonia (except in the German-speaking community)

• In their main residence (not a second home)

• Whether they receive social benefits (RIS, insurance, pension, etc.) or income from work

• Whether or not they are the water account holder.

To apply for assistance from the Water Social Fund, you can contact the Public Social Action Centre (CPAS) in your municipality.

The Water Social Fund (FSE) is financial aid designed to support people experiencing sometimes temporary difficulties in paying their water bills. This fund is financed from a share of each water bill sent to citizens (outside the German-speaking Community). In 2026, this will amount to €0.0339 per m³..

The amount of your instalments is calculated on the basis of consumption in your most recent period. The three quarterly instalments are intended to cover 3/4 of your next adjustment bill. This means that when you receive that bill, only 1/4 of the amount remains to be paid. 

However, if there is a change in your consumption habits (change in household composition, construction of a swimming pool or pond, etc.), you can adjust the amount of your instalments to suit you, avoiding unpleasant surprises.

Our bills are payable within 15 days. If you do not pay within this period, SWDE will send you a first reminder (cost: €6.39)

If the bill remains unpaid, we send a second reminder known as a formal notice (cost: €6.39)

After these two reminders, the unpaid bill is entrusted to an external service provider for collection. Additional costs may be claimed from you, such as interest, an indemnity clause or, where applicable, legal costs.

This simulator allows you to calculate your bill based on a volume in m3 and a standard period of 365 days. 

Practical and interesting!

Each year, SWDE sends you three instalment bills (one per quarter) and an adjustment bill (one per year) after receiving your meter reading. 

If you want to manage your budget more flexibly, you can receive monthly instalment bills. If you choose monthly instalments, you will automatically receive your SWDE bills and communications digitally (e-mail, Zoomit, etc.).
