Abstract
A system and method for dewatering an area in which a catch basin is situated within the area to collect water and conduit conveys the collected water to an elongated discharge chamber having a muzzle at a distal end in communication with a desired outfall body and a substantially closed proximal end. Compressed air released into the proximal end of the discharge chamber forcibly discharges water out of the discharge chamber via the muzzle and into the outfall body to dewater the area. A vent permits escape of air as the discharge chamber fills. Backflow prevention valves maintain discharge out of the muzzle and prevent any water from the outfall body from flowing back into the discharge chamber.
