PWCSA bill pay basics

PWCSA — the Prince William County Service Authority — offers three main ways to pay your water and sewer bill: online through their website, by phone, or by mail. The online method is fastest and gives you a record immediately. Phone and mail payments take longer to post to your account, so plan ahead if you are close to a due date.

Your bill arrives monthly and shows your account number, the amount due, and the due date. You will need your account number to pay online or by phone. If you have not received a bill or cannot find your account number, call PWCSA customer service at 703-335-8877 before attempting to pay.

PWCSA does not charge a fee for online payments made through their official website. Third-party payment services may charge a convenience fee, so stick with the PWCSA portal to avoid extra costs.

Key Takeaways

  • Pay online at pwcsa.org using your account number for the fastest posting and no fee.
  • Phone payments (703-335-8877) work if you prefer speaking to someone, but take one to two business days to post.
  • Mail payments should be sent to the address on your bill and take five to seven business days to reach the office.
  • Set up automatic recurring payments through the PWCSA website to avoid missing due dates.
  • If your payment is late, PWCSA may add a late fee and eventually suspend service, so contact them immediately if you cannot pay on time.

Paying online through the PWCSA website

Go to pwcsa.org and look for the "Pay My Bill" or "Online Bill Pay" link on the homepage. You will be asked to enter your account number and either your service address or the amount of your current bill to verify your account. Once verified, you can enter your payment amount and choose your payment method: debit card, credit card, or bank account transfer.

Online payments post within one business day. If you pay before 5 p.m. on a business day, the payment usually shows in your account by the next morning. Payments made on weekends or after 5 p.m. post the following business day. Keep your confirmation number for your records — PWCSA will email you a receipt, but the confirmation number is your proof of payment if there is ever a dispute.

If you use a credit card, you will pay a small convenience fee set by the payment processor. Bank account transfers and debit card payments through the PWCSA website do not carry a fee. Compare the fee cost against the value of paying on time if you are deciding whether to use a credit card.

Paying by phone

Call PWCSA customer service at 703-335-8877 during business hours (Monday through Friday, 8 a.m. to 5 p.m.). Have your account number and payment method ready. A representative will walk you through the payment and give you a confirmation number. Write down this number and the date and time of your call.

Phone payments take one to two business days to post to your account. If your due date is within two days, paying by phone may not prevent a late fee. Online payment is safer for tight timelines because it posts within one business day.

Paying by mail

Write a check or money order payable to PWCSA. Include your account number on the check. Mail it to the address printed on your bill — this address changes based on which processing center handles your account, so always use the address on your current bill, not an old one.

Mail payments take five to seven business days to arrive and post. If you are paying close to the due date, mail is the riskiest option because the payment may not reach PWCSA before the late fee deadline. PWCSA dates payments by the postmark, not the arrival date, so a check postmarked before the due date may still be considered on time even if it arrives late — but do not rely on this. Pay online or by phone if you are cutting it close.

Setting up automatic payments

PWCSA allows you to set up recurring automatic payments through their website. This removes the risk of forgetting a due date. Log into your account on pwcsa.org, find the automatic payment or recurring payment section, and choose your payment method and frequency. You can set payments for the full bill amount or a fixed amount each month.

Automatic payments come out on the date you choose, usually a few days before the due date. You can change or cancel automatic payments at any time through your account. If your bill amount varies significantly month to month, you may want to set the automatic payment for a lower amount and pay the difference manually when the bill arrives.

What to do if you cannot pay on time

Contact PWCSA as soon as you know you will miss a due date. Call 703-335-8877 and ask about payment arrangements or hardship programs. PWCSA may offer a short extension or a payment plan that lets you spread the amount over several months. The sooner you call, the more options you may have before a late fee is added.

If your account becomes seriously past due, PWCSA will send a notice of intent to disconnect service. This notice gives you a window to pay or arrange a plan before water service is shut off. Once service is disconnected, you will owe a reconnection fee in addition to the unpaid balance. Reconnection typically takes one to three business days after payment is received.

Finding your account number and bill information

Your account number appears on every bill you receive from PWCSA. It is usually a seven to nine digit number printed near the top of the bill. If you have lost your bill, log into your online account at pwcsa.org (create a login if you do not have one) and your account number will be displayed. You can also call 703-335-8877 and provide your service address to get your account number.

Your online account also shows your payment history, current balance, and past bills. This is useful for tracking when payments post and for reviewing your usage over time. Set up your online account even if you pay by mail or phone — it gives you a way to check your balance without calling.

Frequently Asked Questions

Can I pay my PWCSA bill with a credit card online without a fee?

No. Credit card payments through the PWCSA website include a convenience fee charged by the payment processor. Debit card and bank account payments through the official PWCSA website do not charge a fee. If you want to use a credit card, you will pay extra.

How long does it take for a mailed check to post to my account?

Mail typically takes five to seven business days to arrive at PWCSA, and the payment posts a day or two after arrival. Plan for 7 to 10 business days total. If your due date is sooner than that, do not mail a check — pay online or by phone instead.

What happens if I pay after the due date?

PWCSA adds a late fee to your account. The amount varies, so check your bill or call 703-335-8877 to find out the current late fee. If your account stays unpaid for 30 days or more, PWCSA will send a disconnect notice and may shut off your water service.

Can I set up automatic payments for a partial amount each month?

Yes. You can set automatic payments for any amount you choose, not just the full bill. This is useful if your bill varies month to month. You would pay the automatic amount and then pay any remaining balance manually when the bill arrives.

What do I do if my payment was rejected or did not go through?

Check your online account at pwcsa.org to see if the payment posted. If it did not, try paying again using a different payment method or account. If the problem continues, call 703-335-8877 and ask customer service to investigate. Keep your confirmation number from the failed attempt so they can look it up.
