Vacuum wells are an adaptation of deep well systems. Each well in the system is pumped by a submersible pumps, but a vacuum is also applied to each well via a vacuum pump located at the surface. The application of a vacuum allows the wells to be more effective in reducing pore water pressures in poorly draining fine grained soils. In appropriate ground conditions vacuum wells can be a viable alternative to eductors.
