Deep well Dewatering
NCS Fluid Handling Systems is recognized as one of the leading Dewatering Contractors across Canada, Alaska and the Northern USA states. Did you know that carries one of the largest inventories of deep well dewatering pumps and piping in a wide variety of discharge sizes?
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.
Dewatering is just part of the goal, soil stabilization is also part of the objective.
While well-pointing is used to dewater during construction activities such as pipeline installation or integrity digs, an excavation also requires soil stabilization in soils with low permeability with some silts or sandy silts. Well-point dewatering also can be incorporated into applications where shoring or sheet piles are used to reduce hydraulic ground pressure. Dewatering and stabilization are achieved by using Vacuum, generated by pumps in most cases and simply put the vacuum generated increases the hydraulic gradient casing flow to the well point / header and is useful to drawdown more than 18 to 25 feet of ground water in low permeable soils. But 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.
Having Professional Engineers and designers trained to read geological reports and interpret hydrology provides a calculated subsurface water management plan, so call NCS and take the guess work out of the equation, while some contractors guess on well point spacing or well point size the NCS dewatering Systems designers calculated flows put you right in the best “effective zone of influence” also known as “Radius of Influence” and the skilled NCS technicians constantly monitor the system making proper adjustments to the the well points as the soil stabilizes and the NCS dewatering systems gains control of the subsurface water. In some cases, the NCS Fluid Systems engineers may also recommend the use of deep well submersible pumps and to understand the proper application call NCS Fluid Handling Systems Innovation and Design center in Langley BC at 604-720-0190 or 1-888-618-7867. It is possible that your project dewatering requirements may benefit from a system designed with both vacuum style well-points and deep wells, another added benefit of calling NCS Fluid Systems first.
Deep Well Dewatering is the option that NCS Fluid Handling Systems offers for applications where the site has tight construction space limitations or excavations deeper than the effective capability of vacuum type well-points. Deep well dewatering is like well-points with a hole being drilled or bored and cased, however instead of drawing water out using vacuum the dewatering pump is placed at or near the bottom of the bore hole and pushes or pumps water to surface, this pump is known as a submersible pump. The NCS Fluid Systems dewatering designers still calculate the optimum “effective zone of influence” or “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. As with well-pointing the deep well system gains control subsurface water reducing the hydraulic ground pressure by having the water flow directed to the pumps and draw down the water. Similarly, the NCS technicians are trained to monitor and adjust the systems as pumping operations continue and effectively maintain the radius of influence across the entire excavation.
Just like no one pump fits all applications not ever dewatering solution is the same and to determine the best overall solution for your project start the project off right and call the team at NCS Fluid Handling Systems and determine if Well-point dewatering or Deep wells (or maybe a combination of both) is the best solution, overall cost and safety are always a part of the NCS solution.
Ask any NCS team member about our sediment and water treatment business unit that provides complete equipment solutions that can operate in conjunction with our dewatering systems or stand alone.
