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 Canada Can Help

WJ 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.

    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 wells, ejector wells or wellpoint systems.

     

    How WJ Canada Can Help

    With decades of experience behind us WJ have undertaken pumping tests globally from swamps in Nigeria, to central London basements, to the heart of Dubai and the streets of Toronto. Our highly skilled team will ensure that pumping tests are designed, installed and carried out to the highest quality whatever the location.

    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.
