NCS Fluid Handling Systems is one of the leading Dewatering Contractors across Canada, including the territories, Alaska & West coast of the USA.
Providing a wide variety dewatering allows the team at NCS Fluid Handling Systems to remain the best choice for dewatering without limitations and when combined with our sediment control business unit and water treatment options NCS Fluid Handling Systems continues to be the best solution for your full-service dewatering contractor and project support.
Well-point Dewatering is just part of the goal, soil stabilization is also part of the objective.
NCS et al across Canada has one of the largest inventory of well-point dewatering, eductors and dewatering equipment.
Well-pointing is the process used to dewater during construction activities. Also if an excavation also requires soil stabilization in soils with low permeability with some silts or sandy silts. Well-point dewatering is also incorporated into applications to reduce hydraulic ground pressure around shoring or sheet piles.
Dewatered stabilization is achieved by applying Vacuum. This vacuum is generated by increasing the hydraulic gradient casing flow to the well point. The technology is useful to drawdown more than 18 to 25 feet of ground water in low permeable soils. Other than having an excavation with water in it why does NCS Fluid Handling Systems engineering and technicians focus on all the ground and site-specific conditions, the answer is simple it is to also to stabilize soil and deliver a dry excavation for safe entry and installation.
NCS Professional designers are trained to read geological reports & interpret hydrology provides a calculated subsurface water management plan.
NCS team takes the guess work out of the equation. NCS team does not guess on well point spacing or well point size in the NCS dewatering Systems. Our designers calculate the optimum flow that put you right in the best radius of influence. Then the skilled NCS technicians constantly monitor the system making proper adjustments to the well points as the soil stabilizes. Alternatively, NCS Fluid Systems engineers may recommend the use of deep well submersible pumps. To understand the proper application call NCS Fluid Handling Systems Innovation and Design center in Langley BC. It is possible that your project dewatering requirements may benefit from a system designed with both vacuum style well-points and deep wells.
Deep well dewatering is used by NCS Fluid Handling Systems for applications where the site excavations are deeper than the effective capability of vacuum type well-points. Deep well dewatering is a drilled and cased well. Instead of drawing water out using vacuum the submersible pump is placed in the bottom of the bore hole and pumps water to surface. This pump is a submersible pump. The NCS Fluid Systems dewatering designers still calculate the optimum radius of Influence and recommend the placement of multiple pumping wells in an effective proximity to each other and install properly sized deep well submersible pumps. Deep well system gains control subsurface water reducing the hydraulic ground pressure, having the water flow directed to the pumps. NCS technicians are trained to monitor and tune systems during pumping operations. This effectively maintains the radius of influence across the entire excavation.
No dewatering situation is the same.
Call the team at NCS Fluid Handling Systems to determine the best overall solution for your project at the start of the project. Our team will determine if well-point dewatering or deep wells (or maybe a combination of both) is the best solution. We will show the overall cost / benefit.
NCS team member will also provide any sediment and water treatment that is required. This can operate in conjunction with our dewatering systems or stand alone.
Just like no one pump fits all situation’s, not ever dewatering solution is the same. Get the best overall solution for your project starts at NCS.
