This job for Cape Fear Public Utility Authority involves work at 2 of their elevated storage tank sites in Wilmington. Both of the 1.5 million gallon Dawson Street and 17th Street tanks are experiencing the build-up of THMs during the hot summer months. To combat this problem, mixers with floating spray nozzles are being installed inside the actual tanks. To accommodate the new mechanical equipment on and inside the tanks, substantial electrical and SCADA work is also required. New precast concrete buildings were set at each site to house control panels, pull boxes and motor starters. Key subcontractors include Coastline Electric, Medora Corporation, Revere Controls, JENNS LLC, Southeastern Erosion Control, Smith-Carolina Corp and Summit Coastal.
