NGA Business Modules available

NGA was developed with the main focus on point data known as Geosites.

Geosite Types comprise of Borehole, Drain, Dug Well, Lateral/Radial Arm Collector, Mine, Seepage Pond, Sinkhole, Spring, Tunnel, Well Point.

Line and polygon data will be made available in future.

This table gives the latest business module information where data can be captured and stored for the respective Geosite Types.

Business Value Module Name Data
Efficient management of water source Abstractions Groundwater volumes extracted
Discharge Rates Rate at which groundwater is abstracted
Equipment Installed Data regarding the monitoring or non-monitoring type of permanent equipment installed in a Geosite
Geosites linked to Bulk Meter Volumes from non-metered boreholes
Operational Recommendations Recommendation on use of Geosite
Pumping Test Details Interpretation and data analysis of Pumping Tests results
Yield Test The Calibration Test, Constant Yield, Multi-Rate Test and Step Test details as well as the data analysis for the Geosite
