If payment is not received by the due date and the account is scheduled to be turned off, a $50 fee to cover administrative costs is charged. Once the account is scheduled for turn off, ALL payments must be made in cash, certified check, money order, or paid on-line. Meter Services personnel and Emergency Services crews cannot accept payments or grant extensions.

Occasionally, it is impossible to read a meter at the scheduled time – usually due to inclement weather conditions. In such cases, an estimated bill is rendered based on the average consumption for the same period in the prior year. An estimated bill may be a little higher or lower if actual usage was abnormal, however, the next actual reading will automatically adjust for any variation in the estimate.

If you have public water and wastewater service, your bill is determined by the amount of water passing through your meter since the last quarterly meter reading. Wastewater usage is also based on the amount of water delivered to your meter. Public wastewater-only customers are charged a flat rate based on an average use of 14,000 gallons per quarter.

The Capital Facility Connection Recoupment charge is part of the County Council approved Bill #37-11 and targets residents that use more capacity than the capital facility connection charge rate limit of 250 gallons per day.

If you are connected to the public wastewater system but not to public water, and wondering if there is a way to save money on your bill, the Department's Metered Wastewater Account Program may be just what you're looking for. Anne Arundel County has established this program to allow flat rate customers to convert their bills to metered accounts.

The current flat rate charge is based on the average use of 14,000 gallons per quarter for a family of three. If you have less than three people living in your home year-round, or live on your property periodically, or use less than 14,000 gallons of water per quarter, it may be cost-effective for you to convert to a metered account.
A licensed plumber must install a county approved water meter on your private well system. It is their responsibility to contact the Bureau of Utility Operations Meter Services section before proceeding with installation. Call (410) 222-8455 for detailed instructions on proper installation of the water meter and a remote register.

Note: The remote register must be installed 5' above ground level. Your plumber is also required to acquire a connection permit from the Department of Inspections and Permits. This permit is valid for 6 months from the date it was issued and another must be re-issued if time expires. A county inspector must inspect the connection.

In some areas, the County provides wastewater service, but a private company provides water. In those cases, the County wastewater charge is based on the water consumption as reported to by the private company.
