Massanutten Resort

Massanutten Resort

Background:

Massanutten Resort is a 6,000-acre, all-season mountain resort located in the Shenandoah Valley in Virginia that provides guests with several entertainment activities including skiing, golf, and a water park. Painters Pond, located on the resort property, is used to supply water for snow making in the winter and watering of the golf course in the summer. The pond also provides a recreational fishing opportunity for guest who may catch Yellow Perch, Smallmouth Bass, Bluegill Sunfish, Rainbow Trout, and Brook Trout.

To meet stringent fish protection requirements in the State of Virginia, which include a maximum 1.0-mm slot opening and 0.25 fps (0.76 cm/s) through-screen velocity, ISI designed and fabricated a T48-72EA-R screen unit for the site. This wedge wire T screen has two cylinders, each measuring 48 inches (1,219 mm) in diameter and 72-inches (1,829-mm) long. With 1.0-mm slot openings and a 36 percent open area, the screen provides the required 13.5 cfs (8.7 MGD; 1,376 m3/h) at a slot velocity of less than 0.25 fps (0.76 cm/s) and thus meets regulatory requirements. The screen system includes a 72-foot (22-m) long, epoxy coated steel track and includes a water jetting system. The water jetting system allows for resuspension of solids around the T screen to ensure there is no blockage or buildup in the immediate screen area. The jetting system is provides 1 cfs (450 gpm, 102 m3/h) from a pump and control assembly which is outside of the ISI provided system. Anodes are attached to the sides of the screen assembly to provide cathodic protection from corrosion.

Benefit of ISI System

ISI's retrievable brush-cleaned cylindrical screen system provides the following key advantages at this site:

1. The brush cleaning and water jetting systems ensure that the fine-slot wedge wire screen surface will remain free of debris and fouling organisms and therefore maintain compliance with Virginia through-screen velocity requirements and reliably sources water to the resort;
2. The fine-slot wedge wire screen provides pre-filtered water to the snow making and golf irrigations systems at the resort;
3. The in-pond screen location keeps fish in the pond rather than subject them to any type of collection or conveyance system as a part of water withdrawal;
4. The retrievable screen design allows the screens to be raised out of the pond for inspection and maintenance.
