Well Point Dewatering

Wellpoints are 50mm tubes with slots near the bottom that are inserted into the ground from which water is drawn by vacuum generated with a dewatering pump.

Well point dewatering.

The ground water table is influenced by means of drawing it down through the well points spears that are installed around the excavation area. Wellpoint dewatering also known as spear point is an effective dewatering technique. Wellpoint dewatering is a process where groundwater levels are lowered enough to create a stable working environment. What is wellpoint dewatering.

Below methods used to install wellpoint dewatering system. Wellpoint dewatering is a simple yet efficient method of lowering the water table in excavations. Wellpoint systems well points. Pre drill and hand spearing with water jetting system.

While well pointing is used to dewater an excavation it also is used to stabilize soils with low permeability with some silts or sandy silts. The pt well point pumps are positive displacement pumps and fully self priming. In appropriate ground conditions a wellpoint system can be installed speedily and made operational rapidly. The versatile solution ideal for shallow aquifers where the water level needs to be lowered no more than 15 or 20 feet griffin well point systems allow you to pump anything from a few gallons per minute in fine sandy silts to thousands of gallons per minute in coarse sands and gravels.

Mwi wellpoint dewatering systems are specifically suited for removing water from unsettled or unstable ground including weak foundations and trenches. Wellpoint dewatering is widely used for excavations of shallow depths especially for pipeline trench excavations. Wellpoint dewatering aka sandpoint dewatering is the process with an objective to stabilize soil. They can cope with any combination of air and water with no need for a separate priming system.
