Facility Upgrades
Project Overview:
A facility upgrade consisting of a new influent pumping station and headworks building in upstate New York
Dannemora’s headworks building houses critical screening and grit processing equipment, which is used to reduce the level of pollutants in incoming wastewater to a level that will allow it to be discharged — a complex industrial process.
For this project, the work that is visible above grade pales in comparison to the efforts that took place below the surface. The pump station base and the channels under the building are 30 feet below grade and are adjacent to a wetland, so the excavation work prior to construction required multiple dewatering wells and customized shoring boxes to ensure safety and structural integrity. The work also required a very specialized system rigging to lower the 60-foot, 6,700-pound stainless steel grit screw into place in the 30-foot deep channel.
