Integrated reservoir eutrophication remediation plan: Hartbeespoort dam
conference contribution
posted on 2018-02-12, 15:08 authored by P. Venter, M. LigthelmThe Hartbeespoort Dam is situated in a highly developed area in South Africa. Due to high nutrient loads in the dam
unpleasant and even hazardous conditions occur frequently. An integrated phased management and remediation plan has
been developed and is being executed at the dam. The plan provides for short to long-term actions relating to the water
quality of the incoming water, and limnology of and sediments in the dam. Actions include enhanced wastewater treatment
at sewage plants, in-stream treatment, continued regular monitoring, the bio-manipulation of the fish community
for removal of algae and the initiation of community based fisheries. Preliminary analysis indicates that a start-up cost
of about R27.3 million and annual costs of about R9.3 million are required. These costs do not include actions that could
be taken at municipal wastewater treatment plants. The development and implementation of the plan are serving as case
studies for various projects in the Department of Water Affairs and Forestry.
