Pumping Tests

Pumping Tests

WJ has extensive experience of undertaking pumping tests to investigate hydrogeological conditions.

WJ is the leading contractor in the design, installation, management and analysis of pumping tests.

Pumping tests are vitally important to understand the hydrological profile of the site. We recognise that best value engineering solutions are developed through a team approach with the client, Environment Agency and consultant engineers. When possible we participate in early contractor engagement to enable WJ to fully develop a robust groundwater control strategy best suited to the clients needs.

At WJ we provide state of the art pump controls, telemetry and monitoring services to give our clients unrelieved service over our competitors.

 

How WJ Groundwater Can Help

Many of the core services that WJ offer are used in working on ground source energy systems. With over 30 years’ industry leading experience and vast knowledge in all areas, you can be confident that the work will be completed safely, efficiently and reliably.

We provide a complete package that includes feasibility studies, testing, installation and monitoring services through to borehole maintenance, so no matter what the size of your project or where you are located, there is a solution for you. Our professional team will be pleased to advise you on all aspects of ground source energy systems.

With decades of experience behind us WJ have undertaken pumping tests globally from swamps in Nigeria, to basements in central London, to nuclear facilities in Scotland, our highly skilled team will ensure that pumping tests are designed, installed and carried out to the highest quality.

Data gained from pumping tests can be easily accessed in AGS, Excel, or by graphical dashboard format via email or using online software developed by our monitoring software partner Campbell Scientific.

Pumping tests are an important part of any groundwater investigation or groundwater scheme feasibility study. They provide essential information which can affect the planning and build of a project and often required to allow an application of an abstraction license for water supply wells and open-loop ground source energy systems.

Traditional pumping tests are undertaken using a single pumped well and appropriate piezometer array, test pumping and pilot trials may involve working on a small group of deepwells, ejector wells or wellpoint systems.

Thermal Response Tests (TRT) are used to determine the thermal properties of the ground. They are vital for helping develop cost effective designs for closed loop ground source energy systems.

A small portable test rig is used to inject a finite amount of heat energy into a closed loop test borehole over several days. During the test, observations are made about the incoming and outgoing temperatures of the heat transfer fluid, the flow rate of the fluid and the heat energy input.

Analysis of the data can determine thermal conductivity, heat capacity and borehole resistance.

 

How WJ UK Can Help

WJ UK has designed a unique TRT unit for thermal response testing. This allows for rapid installation and monitoring. Our expert management and on-site testing have vast experience in designing and installing TRT systems as well as recording, analysing and interpreting the results to provide you with a high quality service.
