Billing Adjustment Request

Billing Adjustment Request

WSSC Water is committed to providing you with accurate, timely and affordable water and sewer bills. If you receive a bill that is higher than you anticipated, consider whether you’ve had recent leaks, including underground leaks and running toilets, or plumbing repairs. Toilet leaks are the most common cause of unexpectedly high water bills. This video shows you how to detect these often-silent leaks.

Property owners are responsible for maintaining their property’s plumbing, including identifying and repairing all leaks on private property. However, for various reasons, one or more bills may be eligible for a reduction of charges. Learn about our bill adjustment policies to determine if you might be eligible.

Certain plumbing repairs, such as all repairs to underground water lines, must be done by a master plumber registered with WSSC Water. Ask for the master plumber's registration number when contacting them. When hiring a master plumber, we recommend you obtain more than one estimate. Learn more about how to find a plumber.

Customers who experience high bills due to unidentified reasons with an Average Daily Consumption of at least three times the seasonal comparable ADC from the previous year (or current ADC if comparable is unavailable) and are not eligible for any other adjustment as set out in the WSSC Water Code of Regulations, Chapter 3.20.030, may qualify for a High Bill Adjustment (Single-Unit Residential Properties) or a One-Time High Bill Adjustment (Single-Unit Commercial Properties). These adjustment types do not require that a leak be repaired by a WSSC Water licensed plumber, a plumber’s invoice, or a permit.

The sample chart below may help you determine if one of your high bills is three times higher than the comparable:

In this example, the 01/02/20 bill qualifies for a High Bill Adjustment.

If you received a high bill and believe you qualify for an adjustment as indicated in the Code of Regulations, email your request to customerservice@wsscwater.com.

Please include in your email:

• Subject line: Include your account number or service address and adjustment type
• Body of email: Describe the issue and, if applicable, the type of leak, repair date(s), who made the repair(s), and affected billing period(s). If you have an inside meter, please include a current meter reading.

To ensure your water usage has normalized and we are able to provide the best adjustment possible, please provide two “check readings” along with the date of the meter reading at least 10 days apart. Instructions for how to read an inside meter can be found here.

Note: WSSC Water will obtain check readings for customers with outside meters.
