WIMS Case Studies

Tshiping Water Users Association

The Tshiping Water Users Association Case study is a good example of the value of an integrated online reliable and reference-able water data and information management system. Decades of groundwater studies done in isolation produced contradicting results. This is partly due to studies done in different time frames on different areas and in isolation. 

Numerous studies had to start with a data collection programme, which utilised at least 30% of the project budget. With the advent of WIMS, all the hydro data from rainfall to water levels and chemistry since 1950 could be housed on a single, official data warehouse. This included; 4828 unique borehole records, 112 rainfall stations, covering two quaternary catchments and 334 farms. 

Only once all the data was on the same system could meaningful interpretations be done, and myths dispelled. Data reports could be queried and analysed to produce meaningful answers on the sustainability of the groundwater resources and the importance of historical flood events and vegetation on recharge. Once all the data is warehoused on the WIMS system, it becomes information and the future monetary comparison invaluable.

Wims accommodates all Water Data

In the Tshiping Water Users Association Study, the relation between historical and current springs to boreholes, rainfall, water level and water chemistry trends led to a significant conclusion that there is a problem with recharge that is most likely caused by alien bush invasion. Now that the problem has been identified, it can be managed so that additional groundwater can literally be made by controlling alien bush invasion (and reducing evapotranspiration) and WIMS can be used to monitor and manage the process.
