Efficient Silt and Sediment Control During Dewatering
Dewatering low-lying, swampy, or waterlogged areas is a common task on construction sites. However, when water is pumped out, it often carries silt, sediment, sand, and debris that can pollute storm drains and local waterways if left unfiltered.
The Ultra-Dewatering Bag offers a cost-effective and reliable solution for sediment filtration. As water is pumped into the bag, it captures suspended solids—including mud, silt, and other contaminants—allowing only clean water to discharge onto the ground or into stormwater systems.
Key Features:
- Ideal for construction dewatering and sediment control
- Standard and custom sizes available to fit any job site
- Handles up to 4" discharge hoses for high-volume pumping
- Optional quick-connect hose adapter for easy setup and removal
- Durable 8 oz. non-woven geotextile fabric ensures effective filtration
Pro Tip: For optimal performance, place the dewatering bag on a bed of aggregate or straw to enhance flow and maximize filtration across the surface area.
