DEWATERING Services

SF-MGC in collaboration with DWEX & PUMPEX is now one of GCC’s largest and most distinct Turnkey Dewatering & Pumping Solutions Rental and Engineering Services company. DWEX LLC (Dewatering Experts), established in 2010 in the UAE, is one of the leading and award-winning dewatering company providing solutions through its purpose-built facilities.
PUMPEX (Pumping Experts), a brand name under Al Mushtari W.L.L. which is also part of the SF-MGC Group of Companies; offers the most diverse fleet of pumps, high-pressure jetting equipment and tube extraction systems and accessories within the GCC region. We serve the infrastructure pumping needs for; power, water, pipeline, nuclear, environmental, oil & gas, chemicals and the marine and construction sectors.

TOGETHER WE ARE STRONGER
The SF-DWEX-PUMPEX collaboration is an important step for transformation to a large scale dewatering solutions and contracting company. Through our expertise in dewatering technology and system design, we innovate and develop optimum engineering solutions with in-depth consideration for environmental protection, quality, cost-effectiveness & project schedule; developing practical and flexible dewatering systems catering to diverse projects involving complex sites and soil conditions.
We are one of the few companies in the world with the ability to serve customers solutions across the total pumping solutions —from chemical flushing to large volume and flow water transfer and dewatering solutions.

Wellpoint Systems

Wellpoint dewatering systems are used to lower groundwater within shallow excavations & are effective in complex soil conditions. The Wellpoint dewatering generally helps to lower groundwater by around 3 meters. For deeper excavations, a multi-stage Wellpoint dewatering can be used, provided it is technically & commercially viable.

Deepwell Systems

For deep excavations, dewatering can be carried out using a Deep Well dewatering. Deep Wells form a large radius of influence, hence they can be placed at some distance from the excavation. Designing a Deep Well dewatering system is complex as compared to the Wellpoint dewatering, thus all aspects must be considered.

French Drain/Sumps

To control surface or seepage water between the cavities of hard impermeable strata, the French Drain dewatering system proves to be very efficient. French Drain dewatering involves draining water using gravity into sumps. The removal of groundwater can take place with the help of vacuum or submersible pumps.

Overpumping

Overpumping involves the removal of water from an existing reservoir or source & discharging it to a Stormwater M/H, Lagoon or Sea. Overpumping operation requires a suitable set of pumps & piping networks. Care must be taken while designing the system to ensure that the pumping capacity is sufficient to match the flow rate.

Pumping Test

Pumping tests are very helpful in the investigation of ground properties for optimal dewatering system design for projects. Pumping test involves lowering groundwater in controlled flow rates through a Deepwell & recording the water flow rates along with drawdown in pre-defined locations of observation wells at regular intervals of time.

Dewatering System Design- Computer Modeling

Computer modeling simulates steady and non-steady flow in an irregularly shaped flow system with varying aquifer properties to build a dewatering model. Hydraulic conductivity for any layer may differ spatially. Soil properties, plot size, boundary conditions & proximity to water body form the major parameters for dewatering modeling.
