1. In a open-air outdoor wash station for large objects, such as is used for periodic maintenance of transportation vehicles and washing of large animals, wherein said wash station includes a wash deck, a source of wash fluid and means for channeling said wash fluid from said wash deck, wherein the improvement comprises:

  • A. A source of pressurized wash fluid connected through a fluid supply conduit, within a wash station, to a pressure control valve for concurrently (1) reducing pressure of said wash fluid as it flows through said pressure control valve to a wash fluid delivery means within said wash station and (2) increasing pressure within an actuator fine that is in fluid communication with a hydraulic actuator, each of said fluid supply conduit and said actuator line being in fluid communication with each other and separated from said wash fluid delivery means by said pressure control valve; and

    B. A hydraulic actuator mechanically coupled to a waste stream control valve; and

    C. A waste stream control valve, which is mechanically biased in a closed position, mechanically coupled to said hydraulic actuator, whereby an increase in hydraulic pressure in said actuator line causes said actuator to force open said waste stream control valve, and a release of hydraulic pressure within said actuator line removes said opening force from said waste stream control valve, thereby allowing said waste stream control valve to return to a closed position.
