How To Pay Your Water Bill Online

Castle water allows customers to pay for their bills online using either debit or credit card.

All you have to do is fill out a form on the Castle Water portal. You can set up a monthly direct debit to spread payments evenly across the year, which helps avoid seasonal peaks in payments.
