sock drain dewatering

Services at ECD

Sock drain dewatering (also known as sock tile, horizontal dewatering, or sock) is one of the most cost-effective and efficient solutions for combating groundwater on construction sites. Using a specialized dewatering trencher, we install a 5” sock drain (basically a 5-inch diameter corrugated pipe with a filter sock around it) 12ft to 18ft deep in the ground that the groundwater can flow into. Where the sock comes out of the ground is called the header (or tail) which is a 5” HDPE pipe that is solid, which is connected to a dewatering style pump (4” or 6” double diaphragm, 6” piston style, 8” or 12” rotary style pump).

The sock is installed with our trencher anywhere from 12’ to 18’ deep. As we begin to trench in, the run starts with a header pipe that’s 30’ long to ensure that we reach the target depth before we start dewatering and making sure there is enough header left above ground to connect to the dewatering pump/hose. Once we trench in a run, usually in 500’ lengths, we end the run with another section of header pipe. Depending on where the pump is going, the other end of the run will have an end cap on it to ensure there are no air leaks. It is then connected to the pump and discharged away from the area.
