If the soils on your site have low permeability, such as silt, and/or you are digging a deep excavation in stratified soils, eductors may be the solution.
A series of eductor wells are installed and connected to two parallel headers. One header is a high -pressure supply line and the other header is low
pressure return line. When properly installed, eductors are able to apply a vacuum to the formation thus removing the water.
