Cooper Lake Dam Rehabilitation Project

The project consists of various improvements to Cooper Lake Dam and Water Supply Intake System. Major components of the project include: replacing the water supply intake piping, tower structure, valves and controls, and metering chamber; water supply system electrical upgrades; dam safety modifications including raising the crest of the Main Dam, flattening the downstream slope, installing internal filters and drains, and installing geotechnical instrumentation; replacing the principal spillway; and leveling the crest and flattening the upstream slope of the West Dike. The project also includes constructing permanent components of an emergency water supply connection between New York City’s Ashokan Reservoir and the Kingston Water Department’s Pre-treatment Facility on Sawkill Road, and, if so directed, installing temporary water supply piping and operating the temporary connection to provide emergency water supply to the Pre-treatment Facility if required during the Cooper Lake project. This project will utilize a Project Labor Agreement (PLA). As such, this project is exempted from the requirements of Wicks Law and therefore includes one (1) General Contract inclusive of all work items. All electrical work will be contracted and performed within the General Contract.
