Our movement boxes can handle thousands of gallons of water to ensure the speed of the river. The boxes can handle anywhere from two-3 inch bulkheads up to dual
6-inch bulkheads. Placed strategically a few can do a remarkable job.
Our 10 foot long main drains do a great job in supplying the movement boxes and the filtration system. All the while keeping the flow rates low enough to satisfy the health departments.
