South African Inventory of Inland Aquatic Ecosystems
(
WWW:LINK-1.0-http--related
)
A South African Inventory of Inland Aquatic Ecosystems (SAIIAE) was established during the National
Biodiversity Assessment of 2018 (NBA 2018). The SAIIAE offers a collection of data layers pertaining to
ecosystem types and pressures for both rivers and inland wetlands.
The SAIIAE builds on previous efforts while also introducing improvements and several new elements. An
inventory of inland aquatic ecosystems responds to a multi-stakeholder need for the planning, conservation
and management of these systems, as mandated by a number of legislative Acts, including the South
African National Water Act No. 36 of 1998 (NWA) and the National Environmental Management:
Biodiversity Act No. 10 of 2004 (NEMBA). This report provides a full overview of historical efforts in the
inventorying of inland aquatic ecosystems, as well as efforts undertaken between 2015 and 2018 in the
update of data layers associated with river and inland wetland ecosystem types for the NBA 2018.

A subset of the Waste Water Treatment Works file was created by Heidi van Deventer.
In 2019, News24 published a list of 46 sewerage plants that were considered critical ( https://www.news24.com/SouthAfrica/News/sa-has-over-40-critical-sewerage-plants-under-close-watch-20190101). Sediqa Khatieb used the WWTW_pnts_CSIR_2015_AEA file and selected all the points listed as critical in the newspaper article to create the following shapefile. Notes: The listed critical sewerage plant, Rulaganyang WWTW could not be found in the CSIR shapefile.
The News24 document also listed Rooiwal East and Rooiwal North, but only Rooiwal WWTW could be found in the CSIR shapefile.
There were certain spelling differences between the WWTW names listed in News24 article and the CSIR shapefile:
