East Rockaway High School Auditorium Crawl Space
Dewatering & Ventilation Improvement Project

Shallow groundwater stagnates within the crawl space beneath the auditorium resulting in moisture laden air that can have an effect on air quality in adjoining usable spaces. ABE worked with the District’s architect, John A Grillo Architect PC, to design and build a dewatering and ventilation system in the crawl space beneath the auditorium. The dewatering system included the installation of two reinforced collection sumps beneath the crawl space each equipped with float activated ejector pumps that discharges water through a series of newly installed dewatering pipes. The ventilation system is comprised of an intake blower that pulls fresh air into the crawl space through a network of newly installed PVC distribution pipes while a second discharge fan evacuates moisture laden air from the crawlspace discharging it to atmosphere. “As always your guys do great work. Thanks so much.” indicated John A Grillo, and Anthony Quercia, Director of Facilities and Operations (East Rockaway UFSD) added, “John, the guys have been working very good they check in and out with me each day and go over their progress.”
