The UltraTech 9725-OS Dewatering Bag Oil & Sediment Model is a high-capacity stormwater filtration device designed to contain silt, sediment, dirt, sand, and hydrocarbons discharged during dewatering operations. Constructed from nonwoven polypropylene geotextile fabric, it captures both oil and sediment while allowing filtered water to pass through. The 10' x 15' size provides substantial containment capacity for construction, utility, remediation, and site dewatering projects requiring large-volume filtration.
- Oil and Sediment Filtration – Retains both hydrocarbons and sediment, providing combined contaminant control not available with standard sediment-only dewatering bags
- Large 10' x 15' Capacity – Accommodates high-volume dewatering operations with up to 150 cubic feet of containment capacity for collected material
- Accommodates 4" Discharge Hoses – Designed to accept discharge hoses up to 4" in diameter; compatible with the optional UltraTech Hose Connector (Part #9739)
- Heavy-Duty Geotextile Construction – Manufactured from 8 oz. nonwoven polypropylene geotextile fabric with high-strength sewn seams for demanding field conditions
- Stormwater Compliance Support – Helps support compliance with NPDES 40 CFR 122.26 and TMDL requirements when used as part of a stormwater pollution prevention program
