Generals Greene Water Treatment Plant – 1,500-Gpm Facility Replacement & Rehabilitation

Key Accomplishments

• Constructed a new approximately 912-square-foot, wood-frame water treatment building, incorporating concrete footings, foundation walls, floor slabs, masonry, framing, roofing, siding, miscellaneous carpentry, plumbing, and HVAC systems.
• Performed site preparation and earthwork, including erosion and sediment controls, approximately 300 linear feet of silt fencing, a construction entrance, topsoil removal and replacement, excavation, backfilling, stone placement, and removal of excess soil.
• Installed mechanical and process piping infrastructure, including ductile iron water piping, DR 35 PVC sewer piping, valves, fittings, piping supports, and associated equipment connections serving the replacement treatment facility.
• JCC's treatment equipment scope included two LMI Model A751-920HI chemical feed pumps, each with a specified capacity of 24 gallons per day, supporting the facility's chemical treatment operations.
• Provided for installation of a 200-kW Kohler emergency generator with associated electrical infrastructure to support standby power requirements at the water treatment facility.
• Undertook electrical construction involving utility service connections, power and control wiring, conduit, lighting, receptacles, grounding, and electrical connections to the facility's mechanical and treatment equipment.
• Coordinated the reuse and integration of the existing programmable logic controller (PLC) with the facility's control and supervisory control and data acquisition (SCADA) infrastructure.
• Performed building and site finishing activities, including painting, paving, topsoil restoration, grading, landscaping, and seeding associated with the completed treatment facility.
• Coordinated treatment-system testing, startup, and commissioning requirements, including integration with Tidewater Utilities' existing water distribution system to support the continued provision of water service.
