On construction sites across Canada, groundwater can be a substantial unforeseen condition to projects overall success. Dewatering in Canada is essential to effectively manage these conditions. They vary from municipal urban areas to industrial sites. Groundwater knows no boundaries, so managing water below the surface and the proper care and custody during industrial activities are crucial. This becomes important during project execution.
Well-point Dewatering
Wellpoint dewatering uses a series of wells installed into the soil at specific levels. The levels depend on the geological report. These well-point pipes are then connected to a header pipe via hoses and then a vacuum pump system. This process is crucial to the effective dewatering strategy utilized in Canada.
The overall intent of a dewatering systems is removing the water. With a well-point system, the horizontal flow of water is reduced or eliminated. It assists in lowering the ground water. Well-pointing additionally removes the fluid within the soil. In turn, this increases soil stability and reduces soil movement. Well-point dewatering is limited by the laws of nature around vacuum. Typically, it is up to 7 meters deep, depending on some factors.
Benefits
- The presence of water can delay excavation, pose safety risks with unstable soils, and in turn contribute to lost productivity. Well-point systems allow the site operations team to gain control over site water conditions, critical for effective dewatering processes in Canada.
- Reducing groundwater levels provides soil stability.
- Reduction or total elimination of horizontal movement of water in an excavation reduces the risk of adjacent land settlement. When there is horizontal movement of water soil moves with the water which can lead to foundations eroding at the perimeter of other structures shifting.
- With ongoing environmental controls on groundwater discharge and the constituents within the water required additional treatment well-point dewatering allows for a controlled water handling systems for the applicable treatment system. The NCS Team ensures that the industrial water discharged is compliant.
Call NCS Fluid Handling Systems
Before your project starts, consult with the experts. Get us a geo-report so we can advise of an adequately designed systems. This includes number of wells, orientation and spacing. Get us a water sample if possible. This allows the designers to assess the proper treatment if required. Be prepared in advance and save time and unnecessary surprises when dealing with dewatering. Any company planning to quote on a project or already planning a project near water bodies, creeks, rivers, or in areas with a high-water table should consult the NCS Team. Now is the time to do this. Get us involved early and often, whether it’s a site assessment, design a well-point system, or manage everything from design, equipment selection through to a complete and ongoing monitoring crew.
