Louisville and Jefferson County Metropolitan Sewer District (MSD) is responsible for stormwater and wastewater service for the Louisville, Kentucky metropolitan area. A longstanding problem for MSD has been basement flooding due to sewers that are surcharged from wet weather.
A non-traditional program was developed by MSD as a means to address this problem in a cost effective and timely manner. The Plumbing Modification Program began in 1993 as part of the combined sewer overflow program. The program pays for the installation of plumbing modifications inside of customers homes to protect against basement flooding due to wet weather surcharged sewers. Initially established for the combined sewer area only, the program has grown to include the entire combined and sanitary sewer service area. The program has been extremely successful. To date approximately 6,700 installations have been completed with a total construction cost of over $10.5 million.
The Louisville and Jefferson County Metropolitan Sewer District (MSD) was created by Chapter 76 of the Kentucky Revised Statutes in 1946 as a public entity managed by a board of eight. MSD has approximately 600 employees and has complete control of the sanitary sewer, combined sewer and stormwater drainage systems within the majority of Louisville Metropolitan area, which now comprises all of Jefferson County, Kentucky. Refer to Figure 1 for a map of MSD service area.
Due to the recent merger of the City of Louisville and the Jefferson County governments, MSD now works more closely than ever before with the new Louisville Metro government. The Louisville Metro Mayor appoints, with the approval of the Louisville Metro Council, the members to MSD's governing Board. MSD's sanitary sewer and drainage services areas lie within the County which, with a population of 700,300 (2004).
The Backflow Prevention Device Installation Program, which has recently been renamed the Plumbing Modification Program is an on-going voluntary program managed by MSD that installs devices inside of customer homes to protect from basement flooding due to wet weather surcharged sewers. The Plumbing Modification Program has been ongoing for thirteen years and as of May 1, 2006, over 6,700 backflow devices have been installed, with a total construction cost of over $10.5 million.
