Bulk reclaimed water, following treatment and testing according to the water reclamation facility's existing NPDES permit and the conditions provided herein, may be manually distributed from a two-inch hose connected to a quick - connect coupling and gate valve tapped onto an existing four -inch non -potable water line that serves the water reclamation facility.
