Project Summary
Syblon Reid constructed a state-of-the-art 0.50 million gallon per day (MGD) average dry weather flow (ADWF) tertiary wastewater treatment plant to replace the existing 2.3 MGD pond system. The work included the construction of over 3,200 cubic yards (CY) of reinforced concrete structures.
A new influent pump station and headworks were installed; including all pumps, mechanical piping, a trashrack, and a mechanical raking system with a debris screw conveyor. The secondary treatment system included an aeration basin with a secondary clarifier, a return activated sludge/waste activated sludge (RAS/WAS) pump station, and blowers. The tertiary system includes a cloth filter, ultraviolet (UV) light disinfection, a re-aeration basin, chemical feed with storage tanks, and final effluent pumps. Sludge processing includes a sludge belt filter press, screw conveyors, along with drying and storage facilities.
Key Challenges
High groundwater in the area, due to nearby irrigation canals, required Syblon Reid to install dewatering well points around all major excavations.
Syblon Reid worked over 47,000 man-hours to complete this project without a single OSHA recordable incident or loss time accident.
