Functioning aquatic ecosystems and an adequate supply of usable water are fundamental to the survival and development of any nation, and particularly so for water-stressed countries like South Africa. The term useable is directly associated to the quality of water, which needs to be of an acceptable standard. Extensive monitoring programs are required for DWS to monitor the status of water quality in South Africa, and the objective of this dashboard is to summarise the extent of this network.
The source data for this dashboard is the WMS system. The WMS is a suite of computer programmes developed for the Department of Water and Sanitation to provide information for water resource monitoring and management in South Africa.
The data is extracted from WMS system managed by Resource Quality Information Services (RQIS) and exported to NIWIS. RQIS provides national water resource managers with aquatic resource data, technical information, guidelines and procedures that support the strategic and operational requirements for assessment and protection of water resource quality. Functioning aquatic ecosystems and an adequate supply of usable water are fundamental to the survival and development of any nation, and particularly so for water-stressed countries like South Africa. For more details on WMS and contacts for access to data, please visit www.dwaf.gov.za/iwqs/wms/.
Data is extracted monthly.
The following link is for the RQIS and WMS website at DWS, with further links to relevant information about water quality monitoring done by DWS. There are also other information products available on the website.
Steps to follow: Select the first model (dws_analysis_model). Then click on filters. Select a monitoring programme. Select a variable. Select the time period from the Calender. Then click on Map (and select a sub-category eg. Drinking-Health from the additional filter) or Graph

The water quality monitoring dashboard provides a snapshot of the WMS database and may lag behind the live database. The WMS database is the definitive data source. Please see above regarding WMS.
According to this wikipedia article, click here, "...the SI prefix for a thousand is kilo-, with the official symbol k—for instance, prefixed to "metre" or its symbol "m", kilometre or km signifies a thousand metres.
As such, people occasionally represent the number in a non-standard notation by replacing the last three zeros of the general numeral with
"K": for instance, 30K for 30,000.
Kindly note that, in the chart at, national view, there is reference to station data in the region of thousands of stations.
As such the k symbol is then used in the chart legend as per the below, image as an example:
