Pay your Glendale Water & Power bill through their website, by phone, or by mail
Glendale Water & Power (GWP) is a municipal utility serving Glendale, California. You can pay your bill in three main ways: online through their website, by phone with a representative, or by mailing a check. The online method is fastest and shows your payment immediately. Phone and mail payments take longer to process but don't require internet access.
Your bill arrives monthly and shows your water usage, charges, and due date. The due date is typically 20 days from the bill date. If you pay after the due date, GWP adds a late fee. Knowing your account number — printed on your bill — speeds up any payment method you choose.
Key Takeaways
- Pay online at glendalewaterandpower.com using your account number and a debit or credit card for the fastest confirmation.
- Call Glendale Water & Power at their customer service number to pay by phone with a representative or set up automatic payments.
- Mail a check to the address on your bill at least 10 days before the due date to avoid late fees.
- Late payments trigger a fee added to your next bill, so paying by the due date matters even if you pay a few days after.
- Automatic payment through your bank account removes the risk of forgetting and costs nothing extra.
Paying online through the Glendale Water & Power website
Go to glendalewaterandpower.com and look for a "Pay My Bill" or "Online Payments" link on the homepage. You will need your account number, which appears on your bill statement. Enter your account number, then the amount you want to pay. You can pay the full balance or a partial amount.
The website accepts debit cards and credit cards. Some cards charge a convenience fee for utility payments — check with your card issuer before you pay. Once you submit your payment, the system shows a confirmation number immediately. This does not mean the money has left your account yet, but it means GWP has recorded your payment request. Most online payments post to your account within one business day.
If you do not have internet access or prefer not to enter card details online, use the phone method instead.
Paying by phone with a Glendale Water & Power representative
Call Glendale Water & Power's customer service line during business hours. Have your account number and payment method ready. A representative will ask you how much you want to pay and process the payment over the phone. Phone payments are recorded immediately, and you receive a confirmation number before you hang up.
Phone payments also accept debit and credit cards. Like online payments, some card issuers charge a convenience fee. If you want to avoid card fees entirely, ask the representative about paying directly from your bank account — many utilities offer this option at no extra cost, though it may take a few extra days to process.
Paying by mail with a check
Write a check for the amount due and mail it to the address printed on your bill. Include your account number on the check so GWP can match the payment to your account. Mail your check at least 10 days before the due date to give the post office and GWP time to process it. Payments received after the due date trigger a late fee, even if you mailed the check on time.
Do not mail cash. If your check is lost in the mail, you have no proof of payment. Keep a copy of the check or write down the check number for your records.
Setting up automatic payments to avoid late fees
Automatic payment is the easiest way to never miss a due date. Contact Glendale Water & Power and ask to set up autopay. You can authorize them to withdraw money from your bank account on a date you choose — usually a few days before the due date. This costs nothing extra and removes the risk of forgetting to pay.
You can change or cancel autopay at any time by calling customer service. If your bill amount changes significantly one month, you can make a one-time manual payment for the difference instead of waiting for the next autopay cycle.
Understanding late fees and what happens if you miss the due date
Glendale Water & Power adds a late fee to your bill if payment arrives after the due date printed on your statement. The fee amount varies but is typically a percentage of your bill or a flat dollar amount — check your bill or call customer service for the exact fee. This late fee appears on your next bill, increasing what you owe.
If you miss the due date by a significant amount — usually 30 to 60 days — GWP may shut off your water service. Before that happens, you will receive a notice warning you that disconnection is coming. If you receive a disconnection notice, contact GWP immediately to discuss a payment plan or other options.
Finding your account number and bill information
Your account number is printed on your bill statement, usually near the top or in a box labeled "Account Number" or "Service Account." You need this number for any payment method. If you cannot find your bill, call Glendale Water & Power and give them your address. They can look up your account number and tell you what you owe.
Your bill also shows your due date, current charges, and any balance from previous months. Reading your bill before you pay helps you spot errors or unusual charges. If something looks wrong, contact GWP before paying to ask about it.
Frequently Asked Questions
How long does it take for my payment to show up on my account?
Online and phone payments usually post within one business day. Mail payments take 7 to 10 business days depending on postal delivery and GWP's processing time. If you are close to the due date, pay online or by phone to avoid late fees.
Can I pay someone else's Glendale Water & Power bill?
Yes, but you will need their account number. You can pay online or by phone using their account number without being the account holder. If you mail a check, write the account number clearly on it so GWP applies the payment to the right account.
What if I pay too much by accident?
Contact Glendale Water & Power and explain the overpayment. They will either credit the extra amount to your next bill or issue a refund check, depending on their policy. Keep your payment confirmation number so you can reference it when you call.
Is there a discount if I pay my bill early?
Glendale Water & Power does not offer early-payment discounts. You only owe what is printed on your bill. Paying early does not reduce your charges, but it does protect you from late fees and service disconnection.
Can I set up autopay for a partial amount each month?
Most utilities allow you to set autopay for the full bill amount only. If you want to pay a partial amount automatically, call customer service to ask about your options. You can always make additional manual payments on top of autopay if needed.
