Description
Overview
The UltraTech 9729-OS dewatering bag is a rugged stormwater-management solution engineered to trap and filter both oil and sediment during dewatering operations. Measuring approximately 3′ × 4′, this oil & sediment model offers a 6 cu ft capacity and accepts up to a 4″ discharge hose—making it ideal for construction, remediation, or storm-water applications where pumped discharge must be controlled before entering drains or waterways.
Key Features
- Designed to capture oil, silt, sand and other suspended solids, offering combined pollutant control not available in many other bags. 
- Compatible with up to 4″ diameter discharge hose for high-volume dewatering operations. 
- Economical and effective for use in best-management-practice (BMP) programs or stormwater permitting compliance. 
- Lightweight (~2 lb) and easy to deploy on job sites, then dispose of following local regulations.
