If you have ever been to a construction site, then “dewatering” may not be new to you. Dewatering is a vital step in getting a site ready for construction, and it is one of the first activities carried out on a construction site. It involves the removal of excess groundwater from the soil to make it convenient for construction.

The reasons for dewatering are pretty numerous and show how significant it is. Several dewatering methods have been introduced over the years, and they have all proven to be efficient and effective for the task. This article will highlight the wellpoint dewatering system and why it may be the best option for your construction site.

What to Consider Before Choosing a Dewatering System

Indeed, each dewatering system is efficient enough to be utilized in construction areas, but some systems are more suitable than others. Here are some factors to consider before choosing a dewatering system.

  • Nature of the soil in the area
  • Size of the structure to be constructed and how deep into the ground it will go
  • Function and design of the structure
  • Quantity of water present in the soil
  • Time and season of the construction
  • Proposed construction system and the proximity of other structures.

WellPoint Dewatering System

The wellpoint dewatering system is one of the most straightforward yet most efficient methods of removing excess water from the soil. This system involves the introduction of shallow wells at specific positions in the site. These wells are appropriately sized to a predetermined depth and are strategically placed for maximum efficiency.

Pipes are inserted in each well, and the pipes are then connected to a central header pipe that leads to the discharge area. A dewatering pump is attached to the header, and it is used to pump the water from the wells to the discharge area.

The wells in this system have a small diameter, and they are closely spaced to allow a more stable pope connection. Depending on the soil texture, the ground may need to be pre-drilled before the wellpoint is inserted.

Merits and Demerits of the WellPoint Dewatering System

The wellpoint system is a typical dewatering method adopted in several construction sites across different countries because of its benefits. Are you still considering which dewatering method to use for your construction? Here are some reasons why the wellpoint system may be your best option.

  • Wellpoints do not require much for maintenance
  • They are very easily installed
  • They can be used for several construction sites, including residential, industrial, and high rising buildings
  • It is a very effective method of site dewatering
  • The water removed from the ground can be gathered and used for the construction.

The disadvantages of the wellpoint dewatering system are few compared to its advantages, and they are;

  • Wellpoint’s may be difficult to install in areas with stones or hard clay
  • You may need to keep pumping until the excavation is completed.

Conclusion

The wellpoint system may be your best option for dewatering construction sites, and the reasons have been highlighted in this article. However, you must ensure that the wellpoints are correctly installed for an excellent result. High quality dewatering equipment must always be used to guarantee a successful outcome.
