How Cage Trained WaterBoard Teams to Use Drones for Leak Detection and Watershed Monitoring

Problem:

Blantyre and Southern Region Water Board (BWB & SRWB) needed a clear and compliant process to adopt drone technology for leak inspections using thermal drone data and water quality monitoring using multispectral drone data.
Their internal teams required capacity building on RPL regulations, survey-grade data collection, and multispectral and thermal data interpretation.

Solution:

Cage MW delivered a customized data analysis training tailored to BWB’s and SRWB’s operational needs. The course covered RPA and RPL regulatory requirements, airspace permissions, and techniques on ensuring precision and accuracy during data collection. We emphasized the difference between GCPs and RTK positioning, allowing participants to work with real equipment in both field and indoor sessions. The final modules focused on multispectral drone applications, where we trained staff to analyze vegetation stress, turbidity, and TDS indices related to water quality. All instruction included hands-on practice with drone hardware, post-processing tools, and example datasets, ensuring the BWB team could operate independently and safely after the training.

Results:

12 BWB team members trained on CAA-compliant drone ops, from permissions to execution.
Flight missions duration reduced by 27% after optimization of drone settings, thus saving time and cost per mission
Internal team equipped with the capacity to use thermal imaging for pipe leak identification and capability to analyze multispectral data for watershed monitoring and water quality
