Trash Racks: Finger Lakes was contracted to fabricate a new stainless steel trash rack to replace a deteriorated steel rack system. The Project took place in Connecticut, and also included an aluminum pedestrian bridge.
Catholic Protection System: Finger Lakes installed a catholic protection system in this 80’ potable water tower. This project took place in December and was in continuous use during the installation.
Intake Cleaning: This intake is part of our annual cleaning program. The before and after show pictures show a dramatic difference eliminating the costly emergency repairs and shut downs due to lack of water.
Outfall Installation: Finger Lakes did all the underwater work for New Generation power plant in Albany, New York. The project consisted of Verifying Depths of Excavations, Installation of 150’ HDPE Piping, Diffuser Header, Back fill of the Pipeline, Cutting of Sheet Pile
Stop Log Upgrade: Finger Lakes upgraded this stop log door and removed steel from the intake structure. The door and door operator were removed and upgraded with a 14” gate valve recessed within the door.
Fish Ladder: 2 EPDM membranes were installed on the back side of a dam. 1 section of flashboards gets removed to allow herring to swim though. The mats were designed to allow the herring to slide down without injury.
Fish Ladder Armoring: Modifications were made to the fish ladder to help prevent damage from the turbulent pool at the base of the dam. Installation of stainless steel angle irons were used. One leg of the angle was inserted into the concrete and secured with epoxy. The other leg of the angle was bolted against the face of the angle.
Water Gauge: The gauge was fabricated from 1/2 "stainless steel and is 10' in length. Every foot has the elevation number cut out of the stainless.
Concrete Tank Inspection: Finger lakes was called in to inspect 2 concrete lined cooling tanks each holding ½ million gallon of water. The concrete tanks were suspected of having leaks which were causing inefficacy to the cooling system.
Welch Lake: Repair a broken sluice gate stem and a replacement of 12" Gate valve
