Project Details

Scope of work for this project involved furnishing and installing new aeration system diffusers in 10 aeration basins including 24” stainless piping from blower building to the aeration system – we removed and disposed of a total of 2,500 cubic yards of grit and sludge; modifications to existing blower building and replacement of existing blowers with new high efficiency turbo blowers; new internal recycle pump stations including 48”, 36”, 24” and 20” ductile iron piping, valves and appurtenances; structural modifications to splitter box; removal and replacement of the four existing 120’ diameter clarifier mechanisms; modifications to the intermediate pump stations by changing out the motors on the 250hp vertical turbine pumps and re-cutting the impellers; installation of 2,800 lineal feet of 48” double barrel headworks effluent line; flow improvements to the aeration basins with 10 new slide gates and 2 new weir gates; associated electrical and instrumentation improvements. The plant capacity is 24MGD.
