Inside the city of Bowling Green, BGMU water customers pay BGMU’s general (in-city) water schedule, including a monthly customer charge and volume rates per gallon or per 1,000 gallons as shown on BGMU’s July 1, 2025 water rate sheet. At a common modeling assumption of 5,000 gallons per month, city-page estimates land near the mid-$30s before taxes—see the Bowling Green utility page for the exact formula.
Outside BGMU’s water jurisdiction, many properties are served by Warren County Water District (WCWD), a PSC-regulated water utility. For a typical residential 5/8" × 3/4" meter, WCWD’s published billing calculator and rate summaries describe a minimum bill that includes the first 2,000 gallons per month, with additional volume priced in tiered blocks per 1,000 gallons; a 3% utility tax applies on residential bills. Commercial and certain other accounts may see additional state sales tax—see WCWD’s tariff for exceptions.
Storm water and related fees may appear separately (for example, the Plum Springs–Warren County Storm Water Sewer Agency) on some WCWD bills; confirm line items on your statement.
