MSD Residential Bill Charges

Wastewater Service Charge – this is a fixed fee for the maintenance and operation of MSD’s five water quality treatment centers, which process and treat wastewater 24/7/365.

Wastewater Volume Charge – this charge is based on water consumption as measured on the Louisville Water Company meter. A volume rate per 1,000 gallons or CON (Consumption) is the unit of measurement.

Stormwater/Drainage Charge – this fee covers Stormwater, Drainage and Flood Protection Services for the benefit of the entire community. The residential charge is based on one ESU (Equivalent Service Unit), which equals 2,500 square feet of impervious surface—areas such as rooftops and driveways that do not allow water to absorb into the ground.


Need help paying your bill?

Louisville MSD is taking steps to assist our customers who may be facing financial hardships due to the COVID-19 pandemic. We are temporarily waiving new late fees for customers who are having difficulty paying their billing charges incurred during this time. Additionally, during this crisis, Louisville Water will not turn-off water service to customers who fall behind in their payments. These are temporary measures and customers are still responsible for paying their Louisville Water and MSD bill. It is important to contact Louisville Water at 502.583.6610 or MSD at 502.540.6000 if you are having trouble paying your bill.  

“We are all in this together. MSD is committed to working with our customers who may be experiencing financial hardships during this crisis by waiving late fees and publicizing our existing rate assistance programs,” states MSD Executive Director Tony Parrott.
