A Groundwater Database For Cape Town And Environs - A Vision To Optimise Groundwater Management And Education Of The Public

It has been shown over many years that the efficient management of water resources is almost impossible without a database containing historical and up-to-date information and data of high integrity. When it comes to groundwater the situation is even worse as groundwater was often not seen as a viable resource, and if it was used, then in many cases, it was poorly managed due to the lack of monitoring and poor data collection. This has changed in recent years as groundwater now forms a large part of the used water resources in several communities, towns and metros. Therefore, the need for properly managed groundwater data has increased tremendously, leading to urgent requirements for a water database in whatever form. Unfortunately off-the-shelf groundwater databases relevant to the South African market did not really exist for many years, while international packages are expensive and need a lot of adaptation to work for South African conditions. Therefore, most groundwater practitioners used various forms of database software and/or spreadsheets without much integrity leading to data hosted on various computers around South Africa, but not one central system available to be accessed by groundwater managers, scientists or even the public. The Water Research Commission therefore Initiated a research project for the "Development of an integrated Groundwater Database and visualisation tools for the City of Cape Town and Environs", a system that should be so versatile that it could also be applied in other metros, provincial or national offices. This research project will have a huge impact on water resources decision making for the City of Cape Town, as the recent drought has put the City water managers under immense pressure, which was increased by the need to start using more and more groundwater resources, especially for critical City and province institutions like hospitals, clinics and care centres around the Western Cape. The outcome of the project is a "complete" groundwater resources database with links to surface water and meteorological stations and a number of visualisation tools, including an online web-based mapping tool, which is fed by live data from the database and may be used even by the public for groundwater education purposes.
