Abstract
The present invention provides a WTS closure assembly that is easily and quickly secured to and removed from the filter chamber of a WTS. The closure assembly of the present invention provides a bail handle attached to the closure and which utilizes a mechanical advantage, preferably in the form of a pivoting handle which presses a plurality of cams onto the WTS housing, thereby breaking a seal between the closure assembly and the WTS filter chamber, and lifting the closure away from the filter chamber.
