Louisville, KY Set to Build $200 Million Sewer Tunnel

(UC) – In order to protect itself from waterway overflow, the City of Louisville is preparing to build a 20-foot wide underground sewer tunnel, to the tune of $200 million.

The state of Kentucky receives a large amount of rainfall during the year which overflows the city’s outdated sewer system. Due to the age and design of the pipe system, flooding is often a problem during the rainy season.

In 2005, the City signed a Consent Decree with the federal government to reduce the overflows by 2024. The plan involves greatly increasing the amount of storage available for the runoff until it can be safely transported to treatment facilities.

The $1.15 billion project includes treatment center modifications, new drainage pipes, repurposing land use, storage basins, and an underground tunnel capable of capturing and storing 55 million gallons of sewage and rainwater.

The 20-foot wide tunnel will stretch four miles under the city, 18 stories underground. It will cost $200 million and is expected to be completed in 2020.
