How Iowa American Water Auto Pay and paperless billing work
Auto Pay and paperless billing are managed through MyWater. Auto Pay helps pay your bill automatically, while paperless billing sends your bill electronically instead of by mail.
This is useful if you want fewer missed due dates and easier bill tracking. Still, you should confirm enrollment before assuming the next bill will draft automatically.
- Open MyWater.
- Log in or create an account using your Iowa American Water account number.
- Review your current bill and payment due date.
- Choose Auto Pay if you want recurring automatic payments.
- Choose paperless billing if you want bills by email instead of paper mail.
- Keep paying manually until you confirm Auto Pay is active.
Practical advice: If your bill is already close to due, make a one-time payment first. Then set up Auto Pay for future bills after confirming the current balance is cleared.
