What is Dewatering & Groundwater Control?

Dewatering systems are routinely used in the construction industry to provide temporary reductions in ground water levels for structures which extend to below groundwater level. Groundwater control extends this definition to encompass any pumping or recharge system used to manipulate groundwater levels for a range of purposes.

This can be achieved in a variety of ways. It may be necessary to use a pre-drainage method. This involves lowering the groundwater levels in advance of excavation.

Pre-drainage methods include:

Factors such as the type of soil, and the nature of the construction site will all influence which dewatering method will be best suited to your project.

Testimonials

  • WJ designed and installed an effective solution to control the groundwater for our basement excavation and deep core areas. Their work was carried out efficiently, safely and to programme

  • Great, friendly service. Very helpful and easy to work with.

    Guy Bainbridge Quantity Surveyor – Mickleton, M Lambe Construction

  • We engaged WJ Groundwater to drill the new ground source energy well at UCL as they had successfully installed an abstraction well at the same site in 2014. This section of the work required careful planning to align with the main site activities. The WJ team carried out the works on programme and worked well with the main contractor to ensure that this logistically challenging project was delivered successfully.
