Dandy Dewatering Bag®
Controls Sediment Discharge Where Water is Pumped
Dandy Dewatering Bag® takes sediment control in dewatering bags to an all-new level. It’s designed to reliably control sediment discharge in dewatering applications where water is being pumped. When pumped water reaches the Dandy Dewatering Bag, the suspended solids are allowed to settle out of the slowed flow and are fully captured — outperforming other dewatering sediment bags on the market. Dewatering has never been this easy, reliable and convenient.
Benefits of Sediment Control Products
Dandy Dewatering Bag is an exciting innovation in construction dewatering. The benefits of this dewatering filter bag include:
- Easily installs onto discharge hose from dewatering equipment
- More convenient and easier to use than sediment traps or other alternatives
- Delivers regulatory stormwater compliance through sediment filtration
- Available with optional oil absorbents
- Available in three standard sizes to fit any job perfectly
- Beats other dewatering bags in price and performance
Optimal Performance and Convenience
Dandy Dewatering Bag can be used on all dewatering applications and comes in three standard sizes. Designed and built to perform at optimal levels, it is the most convenient and effective dewatering bags on the market today. Once contractors try the Dewatering Bag, they don’t go back to lesser alternatives again.
Its durable filtration fabric helps capture suspended sediment as part of a dewatering system, making it suitable for projects where pumped water requires sediment filtration. Like other sediment filter bags, its performance depends on the sediment load and flow conditions. Contractors choosing among silt bags for dewatering should consider their pump discharge flow rate and available drainage area. Dandy Dewatering Bag works with dewatering systems that route pumped water through a discharge hose.
Made in America By American Workers
Like all our proprietary sediment control products, Dandy Dewatering Bag, is made at our manufacturing facility in Ohio. We maintain high inventory levels so we can drop-ship it in 5 days for fast receipt, no matter where you are in the U.S. If you need a custom size, we’ll fabricate a Dewatering Bag for you and ship it within 5 days. Fast turnaround times are standard for us because we only use raw materials and parts sourced domestically, we manufacture onsite and have an expansive distribution network.
For projects referencing the Build America Buy America Act, contact our team about domestic sourcing details and any documentation required for your specific project.
Step 1
Place lifting straps (not included) under the unit to facilitate removal after use.
Step 2
Unfold Dandy Dewatering Bag on stabilized area over dense vegetation, straw, or gravel (if an increased drainage surface is needed).
Step 3
Insert discharge hose from pump into the Dandy Dewatering Bag a minimum of six inches (6″) and tightly secure with attached strap to prevent water from flowing out of the unit without being filtered.
The only maintenance required for Dandy Dewatering Bag is:
- Replace the unit when it is half full of sediment or when the flow rate of the pump discharge has been reduced to an impractical rate.
- If using optional oil absorbents, remove and replace the absorbent pillow when it nears saturation.
FAQs About Dandy Dewatering Bag® and Construction Dewatering
How does the Dandy Dewatering Bag work?
The Dandy Dewatering Bag connects to a pump discharge hose and filters sediment-laden water through heavy-duty fabric. Suspended sediment is retained inside the bag while filtered water passes through the material.
Is the Dandy Dewatering Bag suitable for construction dewatering?
Yes. The Dandy Dewatering Bag is designed for pumped discharge applications on construction and utility sites, including situations where water must be removed from trenches or excavations. Contractors should select the appropriate size and discharge location for their projects.
How many Dandy Dewatering Bag sizes do you have available?
Dandy Dewatering Bag comes in three standard sizes, with unlimited possibilities for custom sizes available for projects that require different dimensions. Contact Dandy to discuss your pump discharge requirements and the appropriate bag size.
How often should dewatering filter bags be replaced?
Replace the Dandy Dewatering Bag when sediment fills approximately half the unit or when restricted filtration reduces the pump discharge flow to an impractical rate. Check the bag regularly during pumping operations.
Can the Dandy Dewatering Bag remove oil from pumped water?
The Dandy Dewatering Bag is designed primarily for suspended sediment filtration. Optional oil absorbents are available for appropriate applications, but the bag is not a substitute for specialized treatment of contaminated discharge water.
