The West Delaware Tunnel Project is located near Grahamsville in Sullivan County, New York, on land owned by the New York City Department of Environmental Protection (NYCDEP) as part of their West Delaware Aqueduct, which supplies drinking water to New York City. The project is located in the aqueduct between Rondout Reservoir and Cannonsville Reservoir. The project was constructed in 1987 several decades after the construction of the two reservoirs in 1950 and 1964, respectively.

The project includes a 60-foot-long, 66-inch-diameter 压力水管 and a 发电站. The owner has an easement for the use of the property. The powerhouse contains one vertical 弗朗西斯式水轮机/generator with a capacity of 7.5 MW. Water is diverted from the West Delaware Aqueduct to the buried penstock which brings the water to the powerhouse turbine. The water is discharged into a stilling pool (used to reduce the water velocity) which in turn discharges into Rondout Reservoir.

The project operates as a conduit facility. On a weekly basis, the NYCDEP sends a water allotment based upon NY City’s water supply needs. NYCDEP’s system determines the weekly water allotment based upon a number of factors including reservoir levels, inflow forecasts, climatology, and water quality. If there is a given allotment from the NYCDEP, the project owner will then determine the flow rate and timing schedule to deliver the requested allotment over the period specified. Typically, the project will run its turbine at best efficiency to maximize power for a 达到顶峰 schedule.

Waters within the project reach are designated as Class AA drinking water. The associated reservoirs are both impaired for mercury caused by atmospheric deposition and Cannonsville reservoir is listed for phosphorus from agricultural and municipal sources. As a conduit facility, the project does not impact water quality.

The project does not create a barrier to 鱼道 nor are there any migratory fish expected to be impacted by water flowing in the Aqueduct. Both reservoirs are annually stocked with brown, lake, and rainbow trout and natural populations of alewife and smelt can be found in Rondout Reservoir due to its tributary (Rondout Creek).

The powerhouse is located within a fenced property with an area of approximately 4,000 square yards. No lands of significant ecological value are found in the project reach due to its man-made nature.

Threatened and endangered species potentially within the project vicinity include the Bald eagle. A bald eagle nest has been observed roughly 500 feet from the site boundary. The only concern identified was the design of the transmission lines to avoid electrocution hazards associated with the project. The US Fish and Wildlife Service raised this concern, but the transmission lines are not under project ownership.

The project owner consulted with the New York State Division of Historic Preservation which concluded that no historic properties are affected by the operations of the project.

The powerhouse is a secure and fenced area with no opportunity for public access. Recreation at the nearby Rondout Reservoir is strictly controlled and managed by the NYCDEP as it is used for drinking water supply.
