Provider briefing
How this utility’s billing works
Louisville Water Company operates as a public water authority serving Louisville/Jefferson County and portions of Bullitt and Oldham counties. Customers should use the provider’s current account-specific bill and official customer-service instructions as the final authority for deadlines, balances, and service requests.
The published water-rate framework is described as Increasing block residential commodity tiers plus a meter-size daily service charge and, where applicable, a $0.56-per-1,000-gallon elevated-service-area surcharge. The 2026 tariff sets residential commodity rates at $1.70 per 1,000 gallons for the first 2,000 gallons, $4.70 for the next 8,000 gallons, and $4.87 for usage above 10,000 gallons; the standard 5/8-inch or 3/4-inch service charge is $17.82 per month, prorated by actual billing days.. Bills are generated monthly for all customers after louisville water completed the advanced-meter conversion and the final bi-monthly bills in 2025. the 2026 billing reset is designed to place each customer on a predictable monthly schedule, normally covering about 28-32 days; the bill's actual days-billed field controls the daily service-charge calculation., and a typical residential cost reference is Louisville Water's 2026 budget notice says a typical residential customer using 4,000 gallons pays about $30.62 per month for Louisville drinking-water service, including the $17.82 standard service charge and tiered usage. The consolidated Louisville Water/MSD bill is higher because it also includes MSD wastewater, stormwater/drainage, and consent-decree charges; the exact combined total depends on sewer district, property, meter, and usage, so the published $30.62 figure is the defensible water-only benchmark.. These descriptions are useful planning benchmarks; actual charges can change with meter size, usage, sewer averaging, local taxes, drought stages, or account-specific fees.
Wastewater and sewer calculation
Louisville Water jointly bills and receives payment for Louisville Metropolitan Sewer District (MSD) wastewater, stormwater, drainage, and consent-decree charges. Metered wastewater volume is generally tied to the water meter's consumption, while the bill separately identifies wastewater service and volume charges and property/drainage components; the 2026 customer materials do not describe a universal winter-average residential formula. Irrigation or water that does not enter the sanitary sewer may require account-specific metering or MSD treatment, and Louisville Water applies customer payments across water and MSD charges under its published aging and allocation rules.
Meter and infrastructure notes
Louisville Water completed its Advanced Metering Infrastructure conversion for Jefferson County customers, installing wireless meters that transmit usage to Louisville Water receivers and allow Pure Connect customers to monitor usage down to the hour. The AMI program supports remote reads, leak and unusual-usage alerts, monthly billing, and account transfers without a truck roll; the 2024 annual report recorded 284,471 Jefferson County AMI meters, or 98% of that project population, and 2025-26 company material describes the conversion as complete for Jefferson County. Usage is collected for each monthly bill, although estimates can be issued when electronic or manual reads are unavailable and some Bullitt/Oldham expansion areas may have different deployment status.
