Abstract: A passive venting device for venting a building comprising a base comprising (1) a vent structure for permitting gases to pass in and out of the building; (2) an attachment structure coupled to the vent structure for attaching the device; and (3) a gas-permeable screen sized, shaped and positioned to prevent objects from passing through said vent structure, and having an airflow-enhancing configuration for providing greater airflow area than screens of ordinary sloped configuration; and a cover mountable to the base so as to cover the vent structure and permit the free flow of gas. The gas-permeable screen is spaced from the attachment structure in a direction vertically away the roof.

Abstract: A wastewater separator to separate waste from a mixed wastewater stream including one or more of heavy waste, light waste and water. The wastewater separator comprises a separation container, a inlet and an outlet. The separation container comprises (1) a wastewater stream director within the separation container, the wastewater stream director being sized, shaped and positioned relative to the wastewater inlet to direct the wastewater stream along a preferred flow path to permit the light waste to separate from the wastewater stream in a first direction to a collection area and to permit the heavy waste to separate from the wastewater stream in a second direction towards a heavy waste removal area; and (2) a flow-directing outlet baffle within the separation container for directing the wastewater stream to the wastewater outlet from the heavy waste removal area to remove the heavy waste from the separation container.
