This document is the case study for Long Island Emergency Field Hospital Case Study. Field hospitals erected during COVID-19 were equipped with run off N-12 pipeline.

During the COVID-19 pandemic, two temporary, 1,000- bed field hospitals were erected on two Long Island college campuses. The hospitals were large tents made of vinyl making rainwater cascade faster.

Because the turf where the hospitals were built could flood in a medium rain event, stormwater control was vitally necessary. The hospitals were designed on the fly and plans had to be changed to accommodate the equipment of the various trades. The flexibility of N-12 pipe allowed a complete project redesign. The light weight of N-12 allowed it to be easily handled by one- or two-person crews and to be zip tied in order to attach the pipe’s to the buildings.

The system was designed to handle 1,230 gallons (4,656 liters) of rain water per minute. The rain water runoff from the tents conveyed through the pipe and went to swales that were dug to handle the stormwater flow.

The installation was done in April 2020 using 1,200’ (366 m) of 12” (300 mm) N-12 pipe.

Photographs of the project are included.
