Sediment Bag for Pumping a Pond
15 x 25 Dewatering Bag
Question: Do you have a sediment bag for pumping a pond? I am looking for information on the 15' x 25' bag. Also, are these bags reusable? If not, is that the largest size you have available?
Answer: Thank you for your inquiry! We'd be happy to tell you about our 15' x 25' sediment filter bag. This dewatering bag is designed for the storage of sediment, silt, sand, and other materials during a dewatering project. The 15' x 25' dewatering bag is the largest standard size that we offer. However, larger sediment bags can be created upon request. We also have geotextile dewatering tubes for sale, which are available in much larger sizes for higher volumes.
Dewatering bags should be sized based on the volume of water being pumped (pump flow rate), quantity and type of sediment, and the permittivity of the given bag size.
Reusable Dewatering Bags
It is typically not recommended to reuse standard dewatering bags. It is best to dispose of them when the sediment level reaches 50% of capacity.
However, we do also offer special resuable dewatering bags that have a hole pre-built into the material. Holes are then closed using included retainers. These retainers shut the end of the bag during use so sediment cannot escape.
Our sediment bags are fabricated using heavy duty needle punched filter fabric (non-woven geotextile) which provides high permittivity (water flow) and a fine pore structure that allows water to flow through freely, while preventing fine soils from piping through. Other options are woven Monofilament (polypro or PE), which are ideal for high flow, rugged, and high tensile applications.
A sediment bag is an economical effective way to keep within NPDES phase II and Clean Water Act compliance and avoid shut downs and/or fines for not removing material like sediment and organics from pumped water and possibly exceeding TSS permit levels.
