Britford & Surrounding Areas - Geophysical Survey for Geothermal Heat.

PUBLIC NOTICE

GEOPHYSICAL SURVEY

REES ONSHORE SEISMIC LTD (ROS) has been commissioned by STAR ENERGY GROUP PLC to undertake a short geophysical vibroseis survey along each of 4 individual survey lines falling within parts of the Salisbury City Council and following Parish Council areas:

Britford, Coombe Bissett & Netherhampton, Downton and Odstock.

The aim of the survey is to identify and map subsurface geology of the area which is part of an ongoing evaluation of the area for the potential development of geothermal heat. This survey is being undertaken on behalf of the Salisbury NHS Foundation Trust, with the aim of successfully pumping 'hot water' from deep saline water aquifers to provide the local Odstock Hospital with a renewable source of heat.

Surveying activity will be conducted solely across open farmland, and this will initially involve a number of small cylindrical recording nodes being temporarily positioned on the ground surface along each of the survey lines. This will be shortly followed by the operation of two specialist tractor units slowly moving along each survey line in turn. The nodal array will record the 'two way' reflection time it takes for frequency signals, generated at surface level by the tractors, to travel through the varying subsurface rock strata back to the surface. Such acquired data will be processed and the resulting geological detail then incorporated into the geothermal evaluation.

Where the routing of a survey line crosses a public carriageway, field entrance or footpath, no recording nodes will be positioned in such a crossing point, therefore vehicular and/or foot access will not be restricted. However, should a recording node be inadvertently touched, it would pose no danger. Please expect nodes to be left in position along an individual survey line for potentially 2 to 3 days before being retrieved.

Full surveying operations are planned to commence this coming mid-August immediately post the 2024 harvest, and it is expected all activity should be completed within approximately 10 days.

ROS would kindly ask for your patience and co-operation during the survey, and apologises in advance for any inconvenience these works may cause. All properties fronting and falling adjacent to each survey line will receive an information leaflet prior to works commencing.
