Billing cycle

How Frederick County Water and Sewer Billing Works

Frederick County bills water and sewer charges quarterly. Bills are issued on staggered cycles depending on the property’s geographic area.

Quarterly billing

Meter readings and bills are completed on a quarterly basis. A first bill may include prorated charges depending on move-in date and meter reading schedule.

Water usage charge

Billable water charges include quarterly water consumption plus a fixed Ready to Serve Fee.

Sewer charge

Billable sewer charges are based on quarterly water consumption plus a fixed Ready to Serve Fee. Sewer-only accounts may be billed a flat quarterly charge.

🧾
Bill review tip: When checking a high bill, separate usage charges, Ready to Serve Fees, Bay Restoration Fee, interest, late penalties, prior balances and service fees before assuming the meter reading alone is wrong.

High bill and leaks

Why Your Frederick County Water Bill May Be High
