1412134647 (RFP) Discharge Basin Dredging for JEA at Northside Generation Station (NGS)

JEA is seeking a qualified contractor to remove silt and organic material from Northside Generating Station’s discharge flume with clamshell dredging. The flume is a concrete structure, approximately 650 ft long, 45 ft wide and 30 ft deep. Over the last decade material from the river has been accumulating in the discharge basin, settling in the structure from the river water used for cooling. A hydrographic survey completed in December of 2024 estimates 10,264 cubic yards of material within the basin. JEA would like the level of material brought to the invert of the discharge pipe at elevation -28 ft to prevent damage to the support pilings. Removed material can disposed of in the gaps between the discharge basin and inlet flume.
