Attaching Hose Fittings to Silt Filter Bags
Question: I am looking for information on dewatering bag connections. What options do I have available? I have been using one of your dewatering bags and am struggling to figure out how to connect a hose. I am afraid it will just fall right back out.

- Flow Rate. Any time you are looking for a dewatering bag, will you will want to make sure that the bag fabric, size, and style you choose is equipped to handle your site's flow rate. Bags offered here are usually made from either an 8 oz. or 10 oz. material and will have an available flow rate of either 80 gpm/sq. yard or 60 gpm/sq.yard, respectively.
- Volume. Along these same lines, you will also want to make sure that your dewatering bag can handle the amount of sediment you expect to collect. You should consider the size, amount, and type of sediment.
- Placement. If you are worried about the hose, you could also place the bag in a contained area such as a dump truck or drop box. This will help temporarily contain discharge if it comes disconnected, as well as ease the transportation process of your discharge materials.
