Louisville’s sewer and stormwater bills are headed up again this fall, after the Metropolitan Sewer District board signed off on new rates that kick in Sept. 1. The change will tack roughly $3 a month onto a typical Jefferson County bill and about $1.60 for Oldham County customers, with MSD leaders arguing the bump is needed to shore up aging pipes, strengthen flood protection and stay on the right side of federal clean-water rules. The decision came after a 30-day public comment period and a final board vote this month.
According to Louisville MSD, the board approved a measured FY27 rate increase of 3.9% for Jefferson County and 2% for Oldham County, both scheduled to take effect Sept. 1, 2026. The agency presents the hike as part of its broader FY27 budget that covers wastewater, stormwater and flood-protection services across its territory.
Local coverage reports that the new rates will translate to about $3.23 more per month on an average Jefferson County bill, as reported by WDRB, and roughly $1.59 more for Oldham County customers, as reported by WAVE. MSD officials told WAVE the increase is driven by deteriorating infrastructure, rising construction expenses and ongoing clean-water obligations. Executive Director Tony Parrott said the intent is to avoid catastrophic system failures that could trigger major flooding or environmental damage, which would cost everyone far more in the long run.
MSD Says New Cash Will Back More Than 180 Infrastructure Projects
MSD says the extra revenue is earmarked for more than 180 capital projects across its service area, including upgrades to the Paddy's Run Flood Pumping Station and a modernization of the Morris Forman Water Quality Treatment Center. The plan also calls for expanded odor-control work and more attention to clogged catch basins, according to Louisville MSD. The agency says most of the capital spending is driven by state and federal mandates, along with long-delayed repairs to pipes and facilities that in some spots are older than many of the neighborhoods they serve.
Officials are pointing ratepayers to assistance programs for those who might struggle with higher bills, including the Emergency Wastewater Rate Assistance Program (EWRAP) and discounts for seniors. Enrollment details and eligibility guidelines have been published in city communications. MSD's communications include references to customer assistance and an MSD phone number; a Louisville Metro bulletin at Louisville Metro and Louisville Water’s "Drops of Kindness" partnership page are among other resources with information about programs and applications.
