WJ Groundwater engages in sewage over pumping and bypass systems in the Middle East. With the increase in developed utility networks across the region, it has become important for municipal bodies and contractors to conduct regular maintenance works without major disruptions to the existing network. Our temporary over pumping and bypass solutions ensures uninterrupted flow through the main network at the time of maintenance.
We design, engineer, install and commission the most optimal over pumping solution for effective bypass. Our Engineers can assist in calculating the peak flow, temporary piping connections, required pipe length and diameter, drawdown required to avoid flooding upstream manholes, discharge head losses and solid handling parameters. In short, we will choose the best and cost-effective pumping system that is ideal for the site conditions.
WJ can carry out complete temporary installation and operation providing total solution. WJ maintains a large fleet of surface mounted diesel engine pumps high in capacity and with large solids handling capacity spanning 30mm to 120mm. When surface mount is not an option, we can also achieve similar pumping capacity using our well maintained electric submersible drainage and sewage pumps.
WJ Groundwater Limited has assisted several contractors in the Middle East for their pipeline flushing activities. Flushing and cleaning of chilled water pipeline systems is a very critical element of any HVAC project. This procedure is undertaken to flush out any debris or foreign impurities from the pipeline system after commissioning of a newly installed chilled water line. Often utility companies undertake flushing of the existing network every year or a couple of years after. This is a requisite for their regular maintenance program for the network.
WJ assists contractors by supplying the specialized pumping equipment and accessories for the effective flushing of the pipelines. We can also provide in-depth engineering and ensure the flushing velocity and flows are maintained through the sequence of operations. WJ Engineers can also provide the detailed simulation of the network and thereby an indication of what parameters are met and achieved during the actual flushing process. Consultants can also verify node data prior to start of flushing works. This enables us to redesign our temporary system in a very short time for any anticipated site changes.
With our large fleet of high pressure flushing pumps, we can meet any system volume and ensure timely delivery, matching the exact specifications and suited to our client’s project budget. We can supply and install all flushing equipment like pumps, filters, tanks and discharge hose, valves and accessories. WJ offer a rental service as well as a full installation and operation service for flushing pumps and equipment. WJ have delivered several major chilled and condensed water systems in the region.
At WJ, we understand that when there is an emergency, our clients need to control the situation as fast as possible and in the most effective way. By providing backup at unrivalled speed, our emergency response is one of the best in the industry as we provide 24×7 support, 365days of the year. We have established ourselves as the most comprehensive emergency pumping response team in the region. We dedicate several of our resources for planning and execution.
At WJ, we work hard to minimize any risks our customers might face due to flooding and water logging. We help our clients mitigate delays and excessive costs. Our service and operation teams shall swing in action as soon as we receive the call on our helplines. With our growing fleet of dewatering pumps, we can control any flooding situation at hand. WJ Engineers shall select the most suitable and appropriate pumps thereby assuring the most optimal solution.
WJ Groundwater Limited has expanded their expertise through in-house experience of HDPE installation services since its inception. We have worked with several main contractors and is a common sub-contractor for major construction projects in Middle East.
We do offer our HDPE installation services to the regional construction, industrial, water and waste water industries. We carry out HDPE pipeline installation & welding services with Butt Fusion & Electro Fusion techniques. Our operations team consists of skilled, qualified and certified technicians with the know-how of up to date technology and are experienced with precise accuracy and perfection for the works. WJ can supply a wide range of pipes in different class, accessories and fittings. Given the timeframe, we can advise the possibility of completing the installation and commissioning activities at our top pace.
