UK7 - Contract Details Notice
Summary of the contracting process

Natural Resources Wales has completed a procurement process for the "Groundwater Level Network Review" project, involving the Standard Groundwater Index modelling of 40 sites across Wales. As a central government public authority, they contracted the British Geological Survey (BGS) to utilise their unique modelling code. The procurement, classified under the data analysis and supply services category, was awarded using a direct procurement method without competition, given BGS's exclusive capability. The contract, valued at £44,765.22 gross, was signed on 11 August 2025 and is set to run from 18 August to 31 December 2025, primarily taking place across Wales.

This tender represents a valuable opportunity for businesses specialising in geosciences, climate data analysis, and groundwater modelling, especially those with an innovative technological edge in environmental science. While the direct procurement for this contract underscores the importance of specialised skills and proprietary technology in niche markets, future similar procurements could allow other businesses, particularly those capable of developing cutting-edge analytical tools, to collaborate or compete in related projects, fostering industry growth and expertise.

Notice Information

Notice Title

Groundwater Level Network Review - Standard Groundwater Index modelling of 40 sites across Wales

Notice Description

The Geoscience Team have set up a project to review the groundwater level data we hold from across our groundwater monitoring network (130 sites). We have chosen 40 site to look at in more detail using the modelling code the British Geological Survey (BGS) have developed to get a standard groundwater index (SGI). The aim of the project is to use the AquiMod 2 groundwater model (Mackay et al. 2022) in conjunction with historical, bias corrected climate data to reconstruct daily groundwater level time series back to 1894 at each borehole, before calculating an equivalent standardised time series which can be used to assess the historical occurrence of groundwater drought at each borehole. Once the data is processed through the modelling code, we (NRW in house) can then use this data to compare and review groundwater levels from sites with different geologies and geographical areas from around Wales in a standardised way. This allows analysis of drought response and allow us to consider drought management in the future. The BGS have developed the modelling code to determine the SGI. They are the only organisation within the UK that can use the modelling code as the code is not commercially available. As the BGS are the only organisation we must follow the Single Tender Action procurement process to secure a contact for the works.
