Abstract: A water evacuation system includes a sill providing a dam that defines one or more drain ports, an accumulation chamber defined within the interior of the sill and in fluid communication with the dam via the one or more drain ports, and one or more discharge ports defined in a front face of the sill and in fluid communication with the accumulation chamber. An internal ramp is arranged within the accumulation chamber and includes an angled upper surface directed toward the one or more discharge ports to urge water to the discharge ports. Alternatively, or in addition thereto, a pump is in fluid communication with the sill and a float switch is secured to the sill to send a signal to operate the pump when water accumulating in the sill reaches a predetermined level for evacuation.
