Step 1: Register once with Walstroom

Register via this website (first time only) as a Walstroom user. After registration you can use any Walstroom point at local applicable rates. A Walstroom point can be for stay (mooring), power connection or water tap. All Walstroom points have a unique four-digit number, which you can use to turn them on and off using the following steps.

Step 2: Start power supply or water tap, or pay for stay

Select your location.
Select the right service (Stay, Electricity, or Water).
Activate the service using the four-digit number of the Walstroom point using:

  • The Walstroom app (for smartphone of tablet) or
  • The website: log in with your e-mail address and password (at the top of the page) or
  • Your phone: call +31 (0)88 170 7703 (local rate) and follow the instructions.

Paying for stay
You must first pay for stay before using electricity or water.
Your stay, power, and water remain activated until the moment you switch them off.The 24-hour period for your stay starts at the moment you activate (for example at 6:10 pm) and is valid until 24 hours later (in this example 6:09 pm the following day). At some locations, only the overnight stay is paid for, which means that the hours during the day are free. You can find more information on the signs at location.

The tap for drinking water has a maximum duration or a maximum number of liters (shown at the water tap).

Connect your power cable to the Walstroom point you want to activate. After activation the blue LED ring lights up (if available).

Step 3: Turn off power supply or water tap or end stay

You can end your stay, or turn off power and water in the same ways as you started them (see step 2).
You can keep track of the costs via a daily email or SMS (you can change these settings on your personal page of the website or the app).
In addition, you can check your current use and the status of your connections and stay on both the site and app.
IMPORTANT: by removing the power cable from the socket, your Walstroom session has not finished! You must always turn off using the app, website of phone.


You pay afterwards using one of our payment methods which you have chosen during registration.

  • By far the easiest payment method is to set up a direct debit. At the end of the month, the amount is automatically debited from your bank account. You will receive an email with your invoice which has already been paid.
  • If you did not opt for direct debit, you will receive an email with your invoice and a payment link at the end of each month. Via iDeal, Sofort, Mr. Cash of credit card (MasterCard or VISA) you can then pay the outstanding amount.

You can always view your invoice in your personal page on our website (log in at the top of this page). Here you can also change your payment method.
