Avoid Online Scams

There have been a number of articles published recently informing utility customers of a nationwide bill paying scam. In effort to increase awareness of this issue we have included links to the articles below.

Wall Street Journal article.
National Grid article.
LIPA article.

Fairfax Water would like to provide the following tips to keep in mind:

  • Fairfax Water does not ask customers to provide a social security number.
  • Fairfax Water employees have company photo identification with them. Our vehicles and field staff’s clothing bear our company logo.
  • Fairfax Water employees do not receive nor accept any form of payments during service calls.
  • Most water meters are located outside of a customer’s home. Therefore Fairfax Water employees typically DO NOT require access to a customer’s home to read a meter.


Fairfax Water offers the following payment options. A detailed description of each option may be found by clicking one of the buttons below.

FWCustomer/Online Portal

Our new Customer Portal allows you a new way to view and pay your bills.

With registration, you can manage your account by turning off paper bills and/or setting up a recurring debit payment. You can also see your usage and billing history, as well as request notifications. Payments can be made for free using a bank account or pay a small, cost-based fee when paying with a debit or credit card, which are processed by Speedpay®. The portal will also allow you to make a one-time payment without registration.

The portal can be accessed online at www.FWCustomer.org.

If you pay with your credit or debit card, you will pay a $2.95 convenience fee. But, an ACH payment (from your bank account), either one-time or recurring, is free of charge.

Recurring Debit Payment

Recurring Payment is the easiest and most economical way to pay your bill. You must register at our Customer Portal to enroll. You must pay the outstanding balance in full before enrolling.

The amount of your bill is automatically deducted from your checking or savings account on your bill's due date. You still receive a bill so you can maintain records, but you'll never have to worry about paying your bill on time again. We also encourage you to opt for paperless billing.

You are responsible for ensuring sufficient funds in your account on the debit date. If funds are unavailable at the time of the debit, a return payment fee will be applied. If the bank returns a transfer without payment, Fairfax Water has the right to assess a fee equal to the fee charged for return checks. The participant is then immediately responsible to remit full payment and the return payment fee. Upon the second returned payment within a year, your participation will be discontinued.

You may discontinue your participation at any time. But, we require you to submit your change or cancel request a minimum of four business days before the scheduled debit date.

Based upon the services billed and under the terms of this agreement, it is understood that the amount debited may vary. Amounts will fluctuate from billing period to billing period. This authorization allows Fairfax Water to adjust the amount drafted from your bank account to accommodate changes in usage and charges.

Each bill received from Fairfax Water will serve as notice of the amount of each payment deduction.

You may download a PDF version of the Application for Automatic Recurring Bank Draft form by clicking here. Or, call us at 703-698-5800 to request one.
