Well points are a series of small diameter wells connected together by a manifold system that is under vacuum. Our larger rotary pumps pull the maximum (29") vacuum and hundreds of CMF. Well points are best suited for draining excavations that are less than 20' in depth and will perform well in sandy silts to course sand and gravels.
Horizontal Well Dewatering
Horizontal wells can be extremely effective in sandy to gravely soil conditions. This type of dewatering system is installed by a trenching machine and uses large diameter, slotted plastic piping with a "sock" material that acts as a filter for fine sands and silt. This type of dewatering system can be installed to a maximum depth of 18 - 19 feet.
Deep Well System
Deep wells are very effective where soil conditions are consistent throughout the formation and perform well in draining of both the water table or confined aquifers. Depths of these wells can vary from 20' to 150' depending on the application.
