The City of Colfax (City) is proposing to upgrade their existing wastewater treatment plant (WWTP) to mitigate algae growth in the existing Equalization Ponds. The proposed City of Colfax Algae Removal Project (Project) involves installing a new pre-engineered Suspended Air Floatation (SAF) System which will be used for the removal of algae from the flow collected in Equalization Pond Nos. 2 and 3. The project also includes installation of new algae dewatering system as well as various improvements to existing facilities to support the new processes. Existing facilities to be rehabilitated as part of this Project includes the Chlorine Contact Basin (Filter) Pump Station, the Pond No. 3 Pump Station, the Plant Water system, dilapidated electrical panels, and the outdated/inadequate SCADA system. The Project will ultimately allow the WWTP to effectively and reliably remove and dispose of accumulated algae which has historically been a reoccurring issue for wastewater treatment operations.
Items available to be subcontracted and/or material quotations for this project include the following: Clearing and grubbing, sitework, fencing, asphalt concrete paving, concrete, precast concrete components, metal fabrications, paints and coating, hydropneumatic tanks, screw centrifugal pumps, dewatering systems, pre-engineered canopy, pipe, fitting and valves, pipe supports, electrical materials and gear, instrumentation and controls.
