Dewatering Bags & Filters

Contain silt, sediment and oil pumped out during dewatering operations Draining swampy or low-lying areas is a common occurrence in construction. Unfortunately, pumping out the water from these areas also removes a lot of dirt, silt, mud, and debris along with the water. These contaminants can cause problems if they are simply discharged into a storm drain. The Ultra-Dewatering Bag provides an economical and effective solution. By pumping water into the bag, silt, dirt, sand and other pollutants are trapped and filtered so only water escapes to the ground below or nearby storm drains. NOTE: To increase the efficiency of filtration, the bag can be placed on an aggregate or haybale bed to maximize water flow through the surface area of the bag. Product Highlights Detains both oil and sediment/silt, offering a combination of benefits not available in alternative dewatering bags. Standard and custom sizes available. Accommodates up to 4-inch discharge hose. Optional hose connector available - makes connecting and disconnecting Ultra-Dewatering Bags quick and easy. Additional Information The total flow rate through the Ultra-Dewatering Bag can be maximized by getting it off the ground.  While water will flow through a dewatering bag laying flat on the ground, it will be impeded by the solid/saturated soil it is on.  By placing the bag on large aggregate or on hay bales, the water will be less restricted as it flows through the bottom layer of geotextile fabric. The maximum flow rate of the Ultra-Dewatering Bags, when new, is 500 gallons/min. When the Ultra-Dewatering Bag is full, it should be disposed of as directed by the site engineer and in accordance with any local regulations and requirements.  Often times, it can simply be cut open and the contents dispersed. We can do custom sizes (and shapes). If your flow rate is not too high, you can use the attached straps to tie off the bag to the hose.  If water is being discharged at a higher flow rate, a hose clamp may be required (not included).  You can also use our optional hose connector to make the connection quick and easy.

Control the flow of sediment and oil out of headwall and other types of pipes The Ultra-Pipe Sock is engineered using a durable geo-textile filter media that allows large volumes of water to pass through while absorbing liquid hydrocarbons including petroleum, animal and vegetable oils, and other liquid contaminants. This makes it a perfect material for filtering contaminants from a water source and controlling erosion. Also great for pond applications, where vertical pipes extend above the water surface and preventing sediment in-flow during high water events is required. Custom sizes available.
