WATER/ WASTE WATER TREATMENT PLANTS
Belfair Water Reclamation Facility
Mason County Utilities and Waste Management
The Belfair Water Reclamation Facility was a Greenfield project constructed on 56 timbered acres of forest land in Mason County. The project included the construction of a 0.5 million gallon per day water reclamation facility. Facility elements included a headworks with grit removal, coarse and fine screens, odor control and emergency bypass to a lined pond, two Membrane Bio-Reactor (MBR) Trains consisting of anoxic, pre-aeration and MBR basins and equipment, a waste activated sludge facility with recirculation and waste pumping abilities, process building housing controls, permeate pumps, blowers, chemical injection, laboratory, and maintenance facilities, final effluent and disinfection including UV disinfection, clear well, effluent pumping station and filters, treated water storage pond, effluent pipeline and remote controlled effluent spray field. The project achieved a LEED-Silver rating.
Tenino Sanitary Sewer Reuse Facility
City of Tenino
Gibbs & Olson, Inc.
Construction of an entirely new MBR wastewater treatment plant, including a lab and control building. The MBR buiding is attached to the concrete MBR basins and houses the blowers, permeate pumps, nonpotable pumps, sludge pumps and all process equipment. Sitework involved construction of an HDPE-lined equlization basin, sludge storage basin and an infiltration system to reintroduce treated water back into the ground.
Sequim Water Reclamation Facility
City of Sequim
Gray & Osborne, Inc.
Converting the existing oxidation ditch into an equalization basin (EQB),converting the existing EQB into a staged activated sludge aeration basin,modifying an existing secondary clarifier, modifying a splitter box, installing a low pressure high intensity UV disinfection system in an existing channel, and performing associated piping, electrical, instrumentation and telemetry work. Additive items include construction of a new 50-foot diameter secondary clarifier, RAS/WAS pump station, and new effluent fabric filtration system with new filter lift pumps and two flocculation tanks.
Quincy Industrial Wastewater Treatment Plant Fine Pore Aeration System Replacement
City of Quincy
After the successful completion of two prior projects at the Quincy Industrial Wastewater Treatment Plant, BOSS had the distinction of being hand-picked by the equipment manfacturer to perform a third round of upgrades to the facility. Our work consisted of removing sludge from the existing lagoons, demolishing the existing air piping system and replacing it with a much more efficient aeration system. All work was performed during the coldest winter months to avoid major impacts to the plant's production.
Rustlewood Wastewater Treatment Plant Improvements
Mason County Utilities & Waste Management
Hammond, Collier, Wade Livingstone
Providing new mechanical equipment, electrical equipment and appurtenances for the new headworks, a sequencing batch reactor, central pump station, UV disinfection system, influent and effluent flow monitoring, a parshall flume, backup hypochlorite mixing and injection systems and blowers for the SBR basin and sludge holding tanks.
Town of Concrete Wastewater Treatment Plant Improvements
Town of Concrete
HDR Engineering, Inc.
Mount Vernon, WA
Construction of a new membrane bioreactor wastewater treatment plant and associated utility improvements at the existing plant site. The project also included clearing and grubbing, excavation, construction of a 5,500 square foot operations building and a 1,100 square foot shelter covering the headworks equipment.
Twin Oaks Valley Water Treatment Plant
San Diego County Water Authority
San Marcos, CA
San Marcos, CA
When completed, this was the largest membrane water filtration plant in the world. BOSS performed the concrete work on over 70% of the structures for this $165,000,000 facility. BOSS's crew built a total of 21 structures and poured close to 14,000 cubic yards of concrete over a 16 month period of time.
