Dewatering of Franklin Hospital North Wing - P.W. Grosser

Dewatering of Franklin Hospital North Wing

We were hired to find a permanent solution to recurrent flooding in a subterranean wing of a Northwell Health hospital

PWGC was selected by Northwell Health to provide professional engineering services to evaluate and recommend a permanent solution for high groundwater and flooding to a subterranean wing of Franklin Hospital in Valley Stream.

This wing was critical to hospital operations because it housed essential medical laboratories and offices. PWGC designed a new groundwater collection system, pump station and force main to convey groundwater to Valley Stream Brook. Since the installation in 2010, there have been no reports of flooding.

Project Details
