  • Historic streams and ponds were filled in the early 1800’s. Early to mid 1800’s Louisville began constructing the first underground sewer which transported stormwater and wastewater directly to area streams and the Ohio River. In the 1940’s, construction of the 30 mile Ohio River flood protection system began, which included 16 large pumping stations. This system effectively protects most of Louisville from Ohio River flooding, but does not address the flooding from internal drainage. Also, the combined sewers effectively removed the flooding source from sight and, over time, developments were built in floodprone areas.Nearly 26 miles of stream filledOver 560 miles of combined sewer system
