Paying online through the Castle Rock customer portal
Go to the Town of Castle Rock's website and look for the "Pay My Bill" or "Customer Portal" link on the utilities page. You'll create a login using your account number and email address. Once logged in, you can view your current bill, payment history, and water usage.
To make a one-time payment, select your account, enter the amount you want to pay, and choose your payment date. Castle Rock accepts debit cards, credit cards, and bank transfers. Credit card payments may include a processing fee — the portal will show you the fee before you confirm. Bank transfers typically have no fee.
The portal also lets you set up automatic monthly payments so your bill is paid on the same day each month. This prevents late fees and removes the need to remember due dates. You can change or cancel automatic payments anytime through your account settings.
Mailing a check to Castle Rock Utilities
Write your account number on the check memo line. Mail it to the address shown on your bill — typically the Castle Rock Town Hall address. Include the payment stub from your bill if possible; it helps the utility match your payment to your account faster.
Mail takes 7 to 10 days to arrive, and processing adds another few days. If your bill is due soon, mailing a check cuts it close. Call Castle Rock Utilities to confirm they received your payment if you're concerned about a late fee.
Paying in person or by phone
You can pay at Town Hall during business hours. Bring your bill or account number and a check or card. Hours and the exact location are on the Town of Castle Rock website under utilities or customer service.
To pay by phone, call Castle Rock Utilities and have your account number and payment method ready. A representative will process your payment over the phone. Phone payments are useful if you're close to the due date and want to confirm the payment is received immediately.
Understanding your Castle Rock water bill
Your bill shows your account number, the billing period, your water usage in gallons or hundred-cubic-foot units (HCF), and the charges. Castle Rock's rate structure includes a base service charge plus usage charges. The more water you use, the higher your bill.
The bill also lists any taxes or fees applied to your account. If you see charges you don't recognize, contact Castle Rock Utilities before paying — they can explain what each line item covers. Your usage history is visible in the online portal, so you can compare month to month and spot unusual spikes.
What to do if you can't pay on time
Contact Castle Rock Utilities as soon as you know you'll miss the due date. Late fees apply after the due date, and the utility may shut off service if the account falls too far behind. Speaking to them early gives you options — some utilities offer payment plans or can delay disconnection while you arrange payment.
If you're facing a hardship, ask whether Castle Rock participates in any local assistance programs. Some Colorado utilities have emergency funds or work with nonprofits to help residents in crisis. The town's website or a call to their customer service line can point you toward those resources.
Checking for leaks and high water usage
If your bill jumps unexpectedly, a leak is often the cause. Log into the online portal and check your usage history — a sudden spike in gallons used is a red flag. Common indoor leaks are running toilets, dripping faucets, and leaking water heaters. Outdoor leaks may be in your irrigation system or underground pipes.
To find a leak, turn off all water inside and outside your home, then check your water meter. If the meter is still moving, water is leaking somewhere. Call a plumber to locate and repair it. Fixing a leak quickly saves money on your next bill and prevents water waste.
Frequently Asked Questions
How do I find my account number?
Your account number is printed on the top right of your water bill. You'll need it to log into the online portal, pay by phone, or mail a check. If you don't have a bill, call Castle Rock Utilities and provide your address — they can give you the number.
What happens if I pay late?
Castle Rock Utilities charges a late fee after the due date shown on your bill. If the account remains unpaid, the utility may issue a disconnection notice and eventually shut off service. Contact them immediately if you're behind — they may work out a payment plan before disconnection occurs.
Can I set up automatic payments and then cancel them?
Yes. You can set up automatic payments through the online portal and cancel or change them anytime. Log into your account, go to payment settings, and remove the automatic payment. You'll then need to pay manually each month or set up a new automatic payment.
Is there a fee for paying online with a credit card?
Castle Rock may charge a processing fee for credit card payments — the exact amount appears in the portal before you confirm. Bank transfers and debit cards typically have no fee. Check the portal to see which payment method costs less for your situation.
How can I lower my water bill?
Fix leaks, take shorter showers, and run full loads in washing machines and dishwashers. If you have outdoor irrigation, water early in the morning or late in the evening to reduce evaporation. Check your usage history in the portal to see which months use the most water and adjust habits accordingly.
