Danforth CAD Services Provide Effective Solution at Washington Lake Water Treatment PlantTricia Herby
Published Date – Aug 18, 2017
Following the closure of the lake as a drinking source in May 2016, the town of Newburgh, NY has been pushing forward with a solution to clean contaminants from Washington Lake. Danforth is assisting in the efforts to restore the drinking source through the installation of 18 27 foot tall, 12 foot wide filtration tanks. The tanks will use a granular activated carbon system to filter perfluorooctane sulfonate out of the lake water so the town can suspend purchase of drinking water from NYC’s Catskill Aqueduct before that aqueduct is closed for maintenance. The PFO’s contaminated Washington Lake after an accidental spill of fire suppression foams at Stewart Air National Guard Base.
Danforth is working under both a tight deadline and tight jobsite conditions to install these massive tanks. Besides being recessed underground, there are only 5 feet between each tank and 30” clearance between piping. With access proving challenging, Danforth utilized CAD services in the planning stages to ensure all fabrication and site-prep work maintain the strict tolerances required for proper installation.
