Dewatering is a means of eliminating excess groundwater that has proven to be a necessary step for construction. It helps remove the moisture from the soil and makes the site conducive for work. But a significant concern that has constantly challenged dewatering is how and where to dispose of the water extracted. If this water is not discharged correctly, the purpose would be defeated as it will all find its way back into the ground.

It can even lead to a more disastrous outcome, like flooding, which highlights why it is necessary to get rid of the extracted water quickly. This article will enlist excellent water disposal methods for dewatering systems. So, please ensure to read to the end for the many interesting information you will find.

Best Water Disposal Methods

We know of many ways to dispose of unwanted water, but most of these techniques may not be sufficient for water from dewatering systems. This is mainly because dewatering systems often extract large quantities of water from the ground that need specific disposal techniques. Here are some excellent ways to get rid of water from dewatering systems.

  1. Sewage Systems: This system may be the best option, but it is only practical for developed places with a functional and reliable sewage network. The sewage system must have an adequate hydraulic capacity to receive the pumped water, and it must be well channeled to direct the water to an existing disposal point.
  2. Surface Water: Construction workers often utilize this system as it can be practiced in both developed and underdeveloped places. In this disposal method, the water is channeled to flow into an existing body of water like rivers, lakes, or the seaside close to the construction site. Pipelines are often used to channel the water in cases where the water body is farther, and it is necessary to obtain permission from environmental agencies before using this disposal method.
  3. Off-Site Facilities: This method may be the least efficient of the systems listed in this article because it is often only adopted to dispose of smaller water quantities. It involves using tankers to transport the dewatered water to an off-site disposal facility.
  4. Reservoirs: In cases where it is more complicated to channel or transport the water to off-site facilities or other disposal points, reservoirs can be constructed on-site to hold the water for as long as necessary. However, precautions must be taken for this disposal method to ensure that the reservoir is stable and can hold the projected amount of water.
  5. Evaporation Ponds: In all fairness, this method may not be able to get rid of all the water from a dewatering system, but it is often used to reduce the quantity of water to be discharged. It is only feasible in areas with extremely high temperatures, and it involves pumping water into shallow ponds and waiting for evaporation to take its course.

Conclusion

How to dispose of water extracted from construction sites can often breed concerns for constructors because they are often in large quantities. But then, the techniques highlighted in this article are all tested and trusted as some efficient ways to complete this task. Regardless of the method used to dispose of collected water, all systems require the use of high quality dewatering equipment. However, it is essential to consider certain factors before selecting the most suitable disposal option.
