How to pay Castle Rock water bill online step by step
If you are paying online for the first time, do not use a random third-party payment site. Start from the official Castle Rock Water “How to Pay” page or the official MyWaterBill portal so your payment connects to the correct Town water account.
Open the official online portal
Go to the Castle Rock Water online account portal here: CRgov.com/MyWaterBill.
Choose login, sign up, or Quick Pay
If you already created an online account, sign in. If you are new, create a portal account. If you only want a one-time payment, use Quick Pay.
Enter the required account information
For Quick Pay, Castle Rock Water says you need your account number and the street number of the property address. Check your bill before typing the details.
Review the account before submitting
Confirm the service address and amount due. If the amount looks different from your paper bill, check whether a past due amount, service fee, or late charge has been added.
Set up AutoPay if you want recurring payments
Inside the online portal, customers can manage online billing features and set up AutoPay so future bills are handled automatically.
Save your confirmation
After paying, save the confirmation number or receipt. Keep it until your Castle Rock Water account shows the payment correctly.
Important payment warning: Castle Rock Water customer service staff cannot take payment over the phone for security reasons. If you want to pay by phone, use the secure automated system at 844-519-1806.

How Castle Rock Water AutoPay works
AutoPay is the best choice if you want to avoid missing the end-of-month due date. Castle Rock Water’s online portal allows customers to manage payments online and set up automatic payment options after creating or updating their portal account.
This is useful for homeowners, landlords, and busy families who do not want to manually pay every month. Before relying on AutoPay, check that the saved payment method is active and that your next bill shows the payment setup correctly.
- Open the official Castle Rock Water online account portal.
- Sign in or create a new portal account if you have not registered yet.
- Use your account number and property details from your bill.
- Go to the payment settings area and add your preferred payment method.
- Turn on AutoPay or scheduled payment if the portal shows that option for your account.
- Review your next bill carefully to confirm the AutoPay setup is active.
Practical advice: If you recently changed banks, cards, or online portal login details, do not assume AutoPay is still working. Log in to CRgov.com/MyWaterBill and confirm the payment method before the bill becomes due.
