What is Dewatering?
Dewatering is the process of removing water or other liquids, typically surface or groundwater, from a specific location like construction sites, riverbeds, mines, tunnels, flood zones, and other areas where water can accumulate. Dewatering refers to reducing the level of water from the soil with the primary intent of draining water. In many cases, heavy rains cause water to gather in a location that is not wanted, and digging, excavating, or mining below the water table will also create a consistent influx of water requiring dewatering. In some cases, water is used for drilling processes, and the accumulated water has to be pumped out which requires dewatering pumps. Also, dewatering may be required for lakes, ponds, canals, and other waterways construction projects, or even for broken water or sewer pipelines.
Dewatering Methods
One of the simplest methods for dewatering is digging channels to release water, but that requires additional landscape reconstruction and, in most cases, not an option. The most popular type is pumping. Pumps provide complete control over where water is discharged without altering the formation of the land and can move the liquid safely and quickly. There are a variety of pump types that can do the job, but the style of the pump depends specifically on the situation.
DAE Pumps offers the widest range of dewatering pumps that can be deployed in various ways for optimal performance for any project condition. Our dependable submersible pumps and self-priming pumps are ideal for dewatering applications like flood control, wellpoints, deepwells, bypass, and tunneling.
Flood Control
Pumping harmful stormwater caused by heavy rain and flooding is essential for reducing and removing water from construction sites, roads, mines, tunnels, canals, rivers, and other affected areas with increased water levels. Excessive rainfall fills holes in the ground and raises water levels higher than capacity causing damage and destruction that can be very costly. Using submersible or self-priming pumps can quickly remove water that has accumulated after rainstorms, and proactively can be set-up to divert water from known trouble spots to reduce or eliminate damage.
Wellpoints / Deepwells
Wellpoints and deepwell dewatering principles are very similar. Wellpoints are a series of small wells drilled around a specific site for suctioning out groundwater. Deepwells are individual well, typically at deep construction sites with large portions of water for pumping out. Both applications can use a self-priming dewatering pump located at the upper end or a submersible dewatering pump located at the bottom of the well where the groundwater is at, and both work well for these applications.
Bypass
Bypass dewatering is the process of redirecting water or other liquids around a troubled area. Typically, bypass dewatering is used for a pipe break. A self-priming pump or submersible pump suction liquid left because of the broken pipe and transport the liquid past a damaged pipeline location to another section of pipe further down the line. Reliable pumps and properly fitted hoses are essential in the case of broken sewage lines. DAE Pumps make reliable high-pressure pumps that work fast.
