Scoping investigation into the cumulative impacts of point source discharge from Low Volume Privately Owned Treatment Works on river health in the eThekwini Metropolitan Municipality
Expanded Title:Domestic wastewater and its treatment is a global problem that threatens human and aquatic ecosystem health. Treated and untreated wastewater negatively impacts the receiving aquatic ecosystems by altering the water quality and water quantity characteristics within these environments. Domestic wastewater treatment is generally undertaken in large centralised treatment works or in smaller low volume privately owned treatment works (LVPOTW). The impacts of larger centralised treatment works on river health are relatively understood. However, the impacts (direct, indirect and cumulative) of LVPOTW are not that well understood. This is a result of a lack of available information on smaller systems and poorly monitored rivers up- and downstream of these facilities. This lack of information poses a problem for decision makers and authorities regarding the number and size of LVPOTW that can sustainably be accommodated in a given catchment. Therefore, this report is a scoping investigation into the cumulative impacts of point source discharges from LVPOTW on river health in eThekwini Metropolitan Municipality.
