Most project sites require some form of dewatering. Dewatering is the process of pumping sediment-laden groundwater or surface water that has collected on construction sites through a geotextile bag to filter out clean water while trapping dirt, sediment, silt, and more in the bag. By following this process, surrounding streams, storm sewers, and other receiving waters are protected from pollution and erosion concerns are minimized.
When dewatering is taking place you need to have a location for all of that water. Many sites pump that water out from the project site and into nearby lakes, ponds, or drains. This is the major purpose of a dewatering bag.
When you have a dewatering bag on-site you are using it for the purposes of:
- Containing silt and other debris
- Preventing erosion
- Help keep our drinking water clean
It’s important to remember there are times where you do not want to use a dewatering bag such as when the water has been contaminated with oil or grease. For that kind of situation, you will want to use something like a sharkboom or oil blanket.
BMP’s Dirtbag Dewatering Bags
The Dirtbag Dewatering Bag is available in various sizes and includes a fill spout meant to accommodate a 4” discharge hose as well as straps to prevent any pumped water from escaping.
Dirtbag Dewatering bags are most effective when placed over a palette or bed of hay to maximize the exposed surface area and thus water flow. As with any dewatering bag, Dirtbags must be monitored at all times during use to avoid overfilling (overfilling can lead to rupture).
When these bags rupture it leads to a bigger problem than what was originally there. You not only have silt and other debris mixed in with one another but now it’s all pouring out into an area it shouldn’t be.
