ROWD uses the idea of straw bale (or filter sock) filtration but places it in a sturdy steel frame so the amount of water that can be run through without failure is increased while maintaining the mobility of the sled. The sturdy steel construction increases durability and functionality and can withstand transport from one construction site to the next.
The skid mount design aids in mobility while the large frame and solid steel base allows for leveling on any surface. After pushing, pulling or carrying into the dewatering site, leveling is completed by placing material under the solid base to lift the edges and create an efficient dewatering structure. By locking the filter material between concentric rectangles, the ROWD sled also becomes a safer dewatering structure as heavy, water-logged straw bales are prevented from shifting and collapsing, such as in conventional structures.
The ROWD sled will arrive at your jobsite already constructed and ready for easy assembly.
- Unstrap and remove all panels from ROWD sled.
- Insert the outside long panels into the stake pockets and pin the top four corners.
- Install lower row of straw bales: Seven bales down each side with two bales on each end. Bales should fit snug. If they don’t, fill in holes with parts of a straw bale.
- Lay Geotech or filter fabric on the floor of the ROWD sled, pushing fabric into the corners and the inner four stake pockets. Drape fabric over bottom row of straw bales.
- Install inner panels. The long side panels are first, followed by the end panels. Pin top four corners.
- Install top row of straw bales: Seven bales down each side and two bales on each end. Bales should fit snug. If they don’t, fill in holes with parts of a straw bale.
- Lay filter bag in the center of the ROWD sled and connect filter bag to 6-inch inlet pipe.
- Connect discharge pipe to inlet and turn pump on (make sure valve is open for inlet being used and closed for inlet not being used).
- Periodically monitor while pumping.
- Replace straw bales, filter bag and filter fabric as needed.
- To replace bales, remove used filter bag, unpin inner panels, pull out top row of bales, pull out inner panels, pull out filter fabric and pull out lower row of bales. Repeat steps 3-9.
