Water & Waste Water

This project involved maintaining quality operations of a 12 million gallons a day sewer treatment plant through the construction of the rehabilitation of four aeration basins. There was minimal distruption to operations for the plant switch overs to the new equipment.

This project involved extensive upgrades and expansion of the existing facility. It also included new Clarifiers, Sand Filter Structure & Equipment, new U.V. Disinfection System, Installation of new Outfall Line and various supporting construction.

This project involved the construction of new facilities and rehabilitation of existing facilities at the wastewater treatment plant. The project includes construction of a new blower building, headworks upgrades, headworks odor control, new UV building, removal and replacement of six final clarifier mechanisms, new sodium hypochlorite chemical building, electrical control work, reinforced concrete hydraulic structures and installation of owner purchased equipment.

This treatment plant contract involved the construction of a new 20 million gallon pre-sedimentation/equalization reservoir with cover, and a new 2.5 MGD surface water treatment plant. Included in this contract were mechanical rapid mix basins, mechanical flocculation basins, filtration basins, a building with an air backwash blower system, a buried 2.0 million gallon concrete finished water reservoir with chlorine contact channel, a .1 million gallon bolted steel backwash water tank and the tank supply pumps. An operations building was constructed with offices, limited laboratory, maintenance room, electrical room, utilities room and fire protection system. All ancillary equipment, HVAC, electrical, instrumentation systems, associated piping, appurtenances and site work were also included in the contract.

This contract was for the expansion of the existing facility to a design average flow of 0.9 mdg. The expansion included the installation of 9,000 cubic yards of concrete, new headworks, two new and two retrofitted circular activated sludge secondary treatment plant units. New chemical storage, feed equipment, effluent filters, sludge storage tanks, sludge dewatering building and a concrete slab area for co-composing of dewater sludge and green waste were also included in this contract. New administration and maintenance buildings were also constructed.

Included in this project was a new 1.5 MGD surface water treatment plant with package filtration units. The project also included site work, utilities, treatment plant building, ammonia/chlorinator building, pre-sedimentation building, sludge lagoon, piping, instrumentation and electrical.

This project consisted of construction of a 54,000 GPD septage handling facility adjacent to the existing wastewater treatment plant. This septage facility consists of a receiving station, grit chamber, influent pump station, screening unit, two SBR process piping, structural concrete work, electrical and instrumentation. Interface with existing operating plant was required throughout construction.

The Jordan Aquaduct Terminal Reservoir Expansion consisted of the addition of 67 million gallons of water to the existing water reservoir. It can now store 100 million gallons of finished water. Construction included 30,000 cubic yards of concrete and 3,200 tons of reinforced steel.
