Gulfport/Henderson Levee & Drainage District - Pump Stations
The Gulfport / Henderson Pump Station, located in Henderson County, IL, enhances flood protection for hundreds of individuals, Highway 34, and approximately 13,000 acres of farmland. In 2008, a flood damaged the Districts' pumps. Although the pumps were repaired, further work was required to restore the station to its full pumping capacity and protect it from future flood events.
A complete replacement of the Gulfport / Henderson pump station was estimated at $7.8M — $1.8M more than the project’s grant allowance. Klingner’s Engineers maximized the grant’s impact by selectively incorporating existing materials into a design that serves the watershed appropriately.
Working with the Village of Gulfport and Henderson County Drainage Districts #1 and #2, Klingner designed a 316,000 GPM facility — an approximately 216,000 GPM increase from the depleted capacity — that selectively integrated existing elements into a new pump station design. This sheet piling pump intake structure utilizes two electric motor-driven pumps that were previously procured by the Districts and a siphonic design to reduce the amount of energy needed to run. These 42" pumps were designed with a connection system that allows them to connect to the existing 54" discharge pipes. A third pump was installed in a later phase of the project.
All motors, variable frequency drives, telemetry, SCADA, and other critical appurtenances to the pumping units are elevated above the 500-year flood level. Combined with an increased pumping capacity of .68” from the watershed in a 24-hour period, the new station will translate to faster recovery times.
In case of major flood events resulting in power loss, the existing diesel motor in the nearby backup pump station was also rehabilitated.
