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.
Standard size simplifies stocking and compatibility across projects.
