Greenidge completes wedge wire screen project at Seneca Lake intake pipe

Greenidge Generation has completed the intake screen project at its facility in Dresden, Yates County.

The project involved the installation of cylindrical wedge wire screens at the company’s water intake system, which is a critical step in meeting or exceeding all of New York State’s environmental standards.


The company began work on the project in 2017, shortly after receiving a water discharge permit from the New York State Department of Environmental Conservation (DEC). Greenidge was required to meet strict deadlines established by DEC over the course of the project, which included years of detailed study, comprehensive sampling, a pilot study, development of a verification monitoring plan, and more. Company officials say the U.S. Army Corps of Engineers reviewed relevant components of the project and issued approval.

Final state and federal approvals were granted on September 26th, 2022 and October 7th, 2022.

The company says it invested more than $6 million to complete the study, design and installation processes required to complete the wedge wire screen project, which reflect the Best Technology Available according to DEC, and other Greenidge State Pollutant Discharge Elimination System (SPDES) permit requirements.

The construction work was completed by local union labor, including members of the International Brotherhood of Electrical Workers Local 840, Dockbuilders and Timbermen Local 1556, Carpenters Western New York Local Union 276, International Union of Operating Engineers Local 158 & 150 and Millwrights Local 1163.
