The Barbados Groundwater Model and Hydrogeological Assessment, 2025
Case Study: The Barbados Groundwater Model and Water Resources Management Plan
Project Reference: GCF-CCCCC-BWA Modernization
Client: Caribbean Community Climate Change Centre (CCCCC) / Barbados Water Authority (BWA)
Location: Barbados
Duration: 12 months completed in April 2025
Role: Joint Venture Partner (Ntek Design Solutions)
Project Background
Barbados is classified as a water-scarce nation, relying almost exclusively on its karst limestone aquifer for its water supply. With the increasing threats of climate change, rising sea levels, and shifting rainfall patterns, the Barbados Water Authority (BWA) required a sophisticated tool to manage abstraction and ensure long-term water security. Ntek Design Solutions was contracted as a JV partner to develop a comprehensive Groundwater Model and Management Plan to safeguard the island's most precious resource until the year 2100.
Technical Scope & Innovation
Ntek provided specialized hydrogeological expertise to create a predictive digital twin of Barbados' underground water systems. The technical execution was divided into several high-complexity phases:
- Statistical Climate Analysis: Ntek undertook rigorous statistical modeling to determine how regional and local climate events impact precipitation, evapotranspiration, and streamflow. This established the "water budget" necessary for accurate recharge calculations.
- Advanced Recharge Modeling: We developed a proprietary mathematical model to predict seasonal and annual groundwater recharge. This model integrated climate data with geological spatial data to quantify exactly how much water enters the aquifer system under varying weather conditions.
- 3D Hydrogeological Simulation: Ntek implemented a visual three-dimensional (3D) groundwater flow model. This allows the BWA to simulate current flow dynamics and visualize how the aquifer will respond to different "stressors," such as:
- Increased pumping for new developments.
- Prolonged drought periods.
- Climate change impacts on water quality and quantity through 2100.
Strategic Deliverables
- Water and Cliamte Assessment: A comprehensive baseline of the current state of Barbados’ groundwater and provision of climate scenarios for the model.
- Model Selection & Implementation: Identification and deployment of a hydrogeological model specifically tuned to the unique coral limestone geography of Barbados.
- Future Scenario Mapping: Analysis of intra- and inter-annual recharge dynamics and temporal changes in groundwater levels under climate projections reaching the turn of the century.
- Groundwater Management Plan: A strategic reporting framework to guide BWA in managing pumping operations and evaluating the impact of new abstractions.
Added Value: The Web Portal
Beyond the contractual requirements a web portal was developed and deployed a customized Web Portal. This digital interface allows BWA staff to input real-time data directly into the system, ensuring the groundwater model remains a "living tool" that evolves with new field data, rather than a static report.
Impact
The Barbados Groundwater Model provides the BWA with a scientific "crystal ball." By quantifying the impacts of climate change on groundwater levels 75 years into the future, Ntek has equipped the Government of Barbados with the evidence needed to make critical decisions regarding infrastructure investment, water rationing, and sustainable urban development.

This allowed for the precise mapping of the saline-freshwater interface, identifying how far inland seawater has intruded into the coastal aquifer.
- Aquifer Performance Testing: To understand the sustainability of the water supply, Ntek conducted rigorous hydraulic tests. By measuring drawdown and recovery rates, our team calculated critical Aquifer Hydraulic Properties, including transmissivity and storage capacity.
- Hydrogeological Characterization: The data from the geophysical surveys were integrated with physical test results to create a comprehensive profile of the Northern Belizean hydrogeology, identifying high-yield zones versus areas at immediate risk of contamination.
Core Deliverables
- Inception Report: Defined the survey grid and established technical protocols for data collection in the sensitive coastal terrain.
- Geophysical Survey & Data Interpretation Report: A detailed spatial analysis of the subsurface, providing the NHS with visual maps of the saltwater wedge and freshwater lens thickness.
- Aquifer Performance Test, Water Quality Profile & Interpretation: A technical assessment of the aquifer’s ability to yield water under various pumping stresses, providing the evidence base for sustainable abstraction limits. The reporting provided Water Quality Sample Profile of the sites selected.
Impact and Sustainability
This assignment provided the National Hydrological Service with a foundational new dataset that was previously non-existent. By defining the "safe zones" for freshwater extraction, Ntek’s work directly supports:
- Climate Adaptation: Preparing for sea-level rise by identifying at-risk wells.
- Regulatory Planning: Enabling the NHS to issue water permits based on scientific limits rather than estimates.
- Resource Protection: Providing the data necessary to prevent irreversible saline contamination of the northern aquifer.
