How to Pay Your WSSC Water Bill Online and by Mail

WSSC Water bill pay basics

WSSC Water is the water and sewer utility serving Washington, D.C., most of Maryland, and parts of Virginia. You can pay your bill online through their website, by phone, by mail, or in person at a payment center. The method you choose depends on how quickly you need the payment posted and whether you want to set up automatic payments.

Your bill arrives monthly and shows your water usage, sewer charges, and any taxes or fees. The due date is printed on the front of your bill. Payments made online or by phone typically post within one business day. Mail payments take longer — usually five to seven business days from when WSSC receives them — so plan ahead if you are paying by check.

WSSC does not charge a fee for paying online through their official website, by phone with their automated system, or by mail. Some third-party payment processors may charge a convenience fee, so check before you confirm a payment through an outside service.

Key Takeaways

• You can pay online at wsscwater.com without a fee using your account number and a bank account or debit card.
• Phone payments through WSSC's automated system (1-800-828-9772) post within one business day and cost nothing.
• Mail payments take five to seven business days to post, so send them at least two weeks before your due date if you want to avoid a late fee.
• Setting up automatic payments through your bank or WSSC's website removes the need to remember due dates and reduces the risk of late payment.
• Late payments trigger a 1.5% monthly interest charge on the unpaid balance, and service can be disconnected if bills remain unpaid for 60 days.

Paying online through WSSC's 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 checking account, savings account, or debit card. The site uses encryption to protect your financial information.

Enter your account number and the amount you want to pay. You can pay the full balance or a partial amount. Then select your payment method — bank account or card — and enter the routing number, account number, or card details. Review the information before you submit. The payment posts within one business day, though WSSC recommends allowing two business days to be safe.

If you do not have your account number handy, you can search for your account using your service address or phone number. Keep a record of your confirmation number for your records.

Paying by phone or automated system

Call WSSC's automated payment line at 1-800-828-9772. You will need your account number and a debit card or bank account information. The system walks you through entering your payment amount and confirming your financial details. Payments made this way post within one business day.

If you prefer to speak with a representative, you can call the main customer service line at 1-301-206-4600 during business hours (Monday through Friday, 7 a.m. to 6 p.m., and Saturday 8 a.m. to 4 p.m., Eastern time). Representatives can process payments over the phone, but the automated system is available 24/7.

Paying by mail

Write a check or money order payable to WSSC Water and include your account number on the check. Mail it to the address printed on your bill — typically WSSC Water, P.O. Box 37851, Boyce, MD 21714, though this can vary by region. Do not send cash through the mail.

Mail payments take five to seven business days from the date WSSC receives them to post to your account. If your due date is fewer than two weeks away, paying by mail risks a late payment. WSSC applies a 1.5% monthly interest charge to any unpaid balance after the due date, so the cost of mailing late can add up quickly.

If you are mailing a payment close to the due date, consider paying online or by phone instead to may support it posts on time.

Setting up automatic payments

You can arrange for WSSC to deduct your bill automatically from your bank account each month. Log into your account on wsscwater.com, go to the payment settings, and select "Automatic Bank Draft" or "AutoPay." You will need to provide your bank account number and routing number. WSSC will deduct the full bill amount on or shortly after the due date each month.

Automatic payments remove the risk of forgetting a due date and eliminate mail delays. You can change or cancel automatic payments at any time through your online account or by calling customer service. If your bill amount varies significantly from month to month, you may want to review your account before the deduction to make sure the amount is correct.

What happens if you pay late

If your payment does not arrive by the due date, WSSC charges 1.5% interest per month on the unpaid balance. This interest compounds, so a late payment that sits for several months becomes more expensive. A late notice is typically sent within 10 days of the due date.

If your bill remains unpaid for 60 days, WSSC can disconnect your water service. Before disconnection, you will receive a notice and a chance to pay or set up a payment plan. If your service is disconnected, you must pay the full past-due balance plus a reconnection fee to restore service.

If you are having trouble paying your bill, contact WSSC customer service to discuss payment plans or hardship programs. Some information may be available depending on your circumstances.

Frequently Asked Questions

Can I pay my WSSC bill with a credit card?

WSSC's official website does not accept credit cards directly. However, some third-party payment processors may allow credit card payments for a convenience fee. Check wsscwater.com to see which payment methods are currently offered, and compare any fees before you choose a third-party processor.

What if I pay online but my payment does not show up?

Online payments typically post within one business day. If more than two business days have passed and your payment has not appeared, log back into your account to confirm the payment was submitted and received a confirmation number. If the payment was confirmed but has not posted, contact WSSC customer service at 1-301-206-4600 with your confirmation number.

Can I set up a payment plan if I cannot pay my full bill?

Yes. Contact WSSC customer service at 1-301-206-4600 to discuss your situation. Payment plans are available for customers who are unable to pay the full amount at once. The terms depend on the amount owed and your circumstances.

How do I know if my payment was received?

Online and phone payments provide a confirmation number when ready. For mail payments, wait five to seven business days, then log into your account on wsscwater.com or call customer service to confirm the payment has posted. Keep your confirmation number or cancelled check as proof of payment.

What is the difference between my bill due date and my service date?

Your service date is the date WSSC read your meter or calculated your usage. Your due date is when payment must arrive to avoid a late fee. These are different dates — the due date is always printed on the front of your bill and is typically 20 to 30 days after the service date.
