Lexington & Payne CSO Storage Basin

Lexington & Payne CSO Storage BasinLexington & Payne CSO Storage Basin

Plans for the proposed Lexington & Payne Combined Sewer Overflow Basin have changed. Advancements in technology now allow the construction of a deep-rock tunnel, which will replace three basins—Lexington and Payne; Story and Main; and, Thirteenth and Rowan streets. The Ohio River Tunnel Project offers the same storage capacity of the three proposed basins for about the same cost. Click here for more information about the Ohio River Tunnel Project.

April 26, 2016 Public Input Meeting April 26, 2016 Public Input Meeting

MSD held a Conceptual Design Meeting on April 26, 2016 at the Girl Scouts of Kentuckiana Building at 2115 Lexington Road,  concerning the Lexington & Payne CSO (Combined Sewer Overflow) Basin Project—a covered-underground basin. 

At this meeting, MSD provided information about the conceptual design phase of the project, and offered an opportunity for input and comments. This basin will greatly lessen the occurrence of combined sewer overflows—untreated sewage—entering Beargrass Creek during rain events

January 19, 2016 IOAP Public Input Meeting January 19, 2016 IOAP Public Input Meeting

MSD conducted an Orientation Meeting, held on January 19, 2016, introducing a project in your area. The meeting provided information about MSD's Consent Decree, the role of underground storage basins in reducing sewer overflows, and a brief overview of the Lexington & Payne Combined Sewer Overflow (CSO) Basin Project.

This and other basins are part of MSD's larger endeavor to reduce sewer overflows into Louisville's waterways. Planned basins throughout our city are designed to capture rainwater and sewage, which otherwise can overwhelm the sewer system during rain events and flow untreated into our waterways. These underground basins retain the mixture of rainwater and sewage until the rain subsides and system capacity is available. The mixture is then gradually released back into the system and conveyed to a water quality treatment center.
