How to Pay Your WSSC Water Bill Online and by Mail

WSSC Water bill payment methods and where to send payments

WSSC Water (Washington Suburban Sanitary Commission) serves about 1.9 million people in Prince George's and Montgomery counties in Maryland. You can pay your bill online through their website, by phone, by mail, or in person at payment centers. The method you choose depends on how quickly you need the payment processed and whether you prefer automatic or one-time payments.

WSSC Water bills arrive monthly and show your account number, the amount due, and the due date — usually about 20 days after the bill date. Payments made online or by phone are typically recorded the same day. Mailed payments take 7 to 10 business days to reach WSSC and be applied to your account, so mail your check well before the due date to avoid late fees.

Key Takeaways

• Online payment through the WSSC Water website is the fastest method and requires only your account number and payment information.
• Phone payments can be made by calling WSSC's automated system or speaking with a representative, and the payment posts the same day.
• Mailed checks should be sent at least 10 days before your due date because postal delivery and processing take time.
• Late payments trigger a 1.5% monthly charge on the unpaid balance, so paying on time matters even if you pay a few days after the due date.
• WSSC offers budget billing and automatic payment options that spread costs evenly across the year or withdraw from your bank account each month.

Paying online through the WSSC Water website

Go to wsscwater.com and look for the "Pay My Bill" or "Online Bill Pay" link on the homepage. You will need your account number (found on your bill) and either a debit card, credit card, or bank account information. The website accepts Visa, Mastercard, American Express, and Discover, as well as electronic bank transfers.

Enter your account number, the amount you want to pay, and your payment method. Review the details before submitting. WSSC charges a convenience fee for credit and debit card payments — the fee amount appears before you confirm the payment. Bank account transfers typically have no fee. Once you submit, you will receive a confirmation number on screen and by email.

Online payments are processed when ready, and your account is updated the same business day. If you pay after 5 p.m. on a weekday or anytime on a weekend, the payment may not post until the next business day. You can set up a one-time payment or enroll in automatic recurring payments through the same portal.

Paying by phone

Call WSSC Water's automated payment line at 301-206-8000 to pay with a debit or credit card without speaking to anyone. Have your account number and card information ready. The automated system will confirm the amount and payment date before processing.

If you prefer to speak with a representative, call the same number during business hours (Monday through Friday, 7 a.m. to 6 p.m., and Saturday 8 a.m. to 4 p.m., Eastern time) and ask to pay your bill. A representative can answer questions about your account, discuss payment plans, or help you set up automatic payments. Phone payments post the same day if made before 5 p.m. on a business day.

Mailing a check or money order

Write your account number on the check or money order and mail it to the address shown on your bill. WSSC's mailing address is typically WSSC Water, P.O. Box 37851, Boyce, MD 20772, but confirm the current address on your bill because it can change. Do not mail cash.

Mail your payment at least 10 business days before the due date. The U.S. Postal Service takes 3 to 5 business days to deliver mail in the WSSC service area, and WSSC takes another 3 to 5 business days to process and post the payment. If your check arrives after the due date, WSSC will charge a late fee even if you mailed it on time, so the postmark date does not protect you — only the date WSSC receives and records the payment matters.

In-person payment at WSSC offices and authorized locations

You can pay in person at WSSC Water's main office in Laurel, Maryland, or at authorized payment centers in Prince George's and Montgomery counties. Payments made in person are recorded when ready. WSSC's website lists current payment center locations and hours, which vary by location.

Bring your account number and payment in the form of cash, check, or money order. Credit and debit cards are not accepted at in-person locations. Some utility payment centers (such as those run by local governments or third-party bill pay services) may also accept WSSC payments, but confirm before visiting.

Setting up automatic payments and budget billing

Automatic payments withdraw money from your bank account on a date you choose each month, usually around your bill due date. Enroll through the WSSC Water website or by calling 301-206-8000. You will need your bank account number and routing number. Automatic payments have no fee and may support you never miss a due date.

Budget billing spreads your annual water and sewer costs evenly across 12 months, so your bill is the same amount each month instead of varying with seasonal use. This helps with budgeting but does not reduce your total annual cost. You can request budget billing by phone or through your online account. WSSC recalculates your budget amount once a year based on your actual usage.

Late fees, payment plans, and what happens if you do not pay

If your payment is not received by the due date, WSSC charges a 1.5% monthly late fee on the unpaid balance. The fee compounds monthly, so a bill that stays unpaid for several months accrues significant charges. WSSC also sends a past-due notice and may eventually disconnect your water service if the account remains unpaid for 60 days or more.

If you cannot pay your full bill by the due date, contact WSSC before the due date to discuss a payment plan. Representatives can work with you to set up a schedule that fits your situation. Calling before you miss a payment is much easier than trying to resolve a disconnection notice later.

Frequently Asked Questions

Is there a fee to pay my WSSC bill online?

Credit and debit card payments through the WSSC website incur a convenience fee that WSSC discloses before you confirm payment. Bank account transfers typically have no fee. Phone payments with a card also charge the convenience fee. Mailed checks and in-person payments have no fee.

How long does it take for my mailed check to show up on my account?

Mailed payments take 7 to 10 business days total: 3 to 5 days for postal delivery and 3 to 5 days for WSSC to process and post the payment. Mail your check at least 10 days before the due date to be safe. The postmark date does not matter — only the date WSSC receives it.

Can I pay someone else's WSSC bill if I have their account number?

Yes, you can pay another person's bill online or by phone if you have their account number. You do not need to be the account holder. However, if you want to set up automatic payments or make changes to the account, you will need to be listed as an authorized user or the account owner.

What should I do if I think my WSSC bill is wrong?

Contact WSSC Water at 301-206-8000 to dispute the bill before paying. A representative can review your account history, check for meter errors, and explain the charges. You can request a meter test if you believe the meter is reading incorrectly. Do not ignore a bill you think is wrong — contact WSSC to resolve it.

Can I set up automatic payments if I do not have a bank account?

Automatic payments require a bank account or a debit card linked to one. If you do not have a bank account, you can pay online with a credit or debit card, by phone, by mail, or in person. Some community organizations and nonprofits offer financial services that may help you open a basic account.
