Dewatering Bag (2.5mL x1.5mW) 200mm neck located on width

SHS-CHDWB03 Chatoyer Dewatering Bag – 2.5m x 1.5m (200mm Neck)

High-Performance Silt & Sediment Control for Large-Volume Dewatering Applications

Overview

The CHDWB03 Chatoyer Dewatering Bag is engineered to efficiently capture silt, sediment, and suspended solids during high-volume dewatering operations on construction, mining, and environmental sites. Measuring 2.5 metres in length and 1.5 metres in width, this large-capacity filtration solution provides a controlled method for discharging water while preventing contaminants from entering stormwater systems or surrounding environments.

Constructed from 270gsm non-woven geotextile fabric, the bag allows water to pass through while retaining suspended solids with 99.0% filter efficiency. The integrated 200mm diameter neck, positioned on the short side/top of the bag, ensures easy connection to large-diameter discharge hoses for efficient and secure operation. With a 1m³ sediment capacity, it is ideal for extended dewatering projects.
