6 Factors to Consider When Choosing the Right Dewatering System
Construction workers always face enormous challenges when working in wet construction sites. Most of these projects involve excavating closer to high groundwater tables and thus require constant dewatering. Choosing equipment such as wellpoint dewatering systems and dewatering pumps can be quite useful in such scenarios. Continue reading for six significant factors to consider when selecting the right dewatering system.
Excavation Type
Conventional wellpoint systems are safer and economical while dewatering ground areas with shallow water table levels. However, water levels up to 20-30 feet deep require the use of deep well systems for effective dewatering. Consider employing a combination of wellpoint and deep well systems for proper dewatering in locations surrounded by cofferdams.
The Pump's Efficiency
Most contractors consider choosing bigger surface pumps to accomplish dewatering tasks quickly. But this approach may mean sacrificing the pump's energy efficiency. However, newer technologies in dewatering pumps today have resulted in reduced energy consumption. It's imperative to consider using minimum fuel consumption pumps in lower loads. Also, select dewatering systems that can handle multiple application demands without jeopardising burnout.
The Pump's Versatility
It's always wise to choose a dewatering system that's feasible for multiple functions. Thus, it's crucial to analyse the pump's components as well as design. Consider dewatering pumps that come along with a wide range of accessories, modular designs and multiple application performance for easier upgrades.
Intermittent Pumping Procedure
Double or single dewatering shifts help minimise project's daily labour costs. However, this principle doesn't apply in tremendous dewatering depth and pervious or homogenous subsoil conditions. In these scenarios, the pumping operation is vital. Contractors must accurately operate the pumps to ensure that they are taking large drawdowns in each single or double shift.
Portability and Size
Today, the manufacturing industry has adopted lighter, smaller and potable dewatering systems. It's imperative to choose multipurpose pumps that have built-in features that promote portability and safety. Some excellent features include integrated lifting and trailer options. Before purchasing, it's crucial to inquire about the availability of additional safety options to aid in pump mobility on job sites whenever needed.
Easy to Service
Any downtime in dewatering systems is costly due to lost time. For this reason, consider choosing dewatering pumps that are easily serviceable and have longer repair intervals. They must have the shortest servicing intervals and allow for both remote and on-site repairs.
Conclusion
These are the six major factors to keep in mind when selecting the right dewatering system for any application. As for specialised applications, it's crucial to consult with the manufacturer for the right dewatering pump.
