The Hartbeespoort Dam Remediation Project, Harties Metse a me

30 April 2009

Turning a liability into an asset

One of the major obstacles facing the Hartbeespoort Dam remediation project, Harties Metse a me, is to turn the huge liability presented by the heavily polluted and generally abused body of water into a self-sustaining asset that can generate sufficient income for its own upkeep. One way is to harvest the material that in the water is a pollutant but once on dry land can actually be beneficially utilised - a process referred as beneficiation.          Read more ...

Restoring the population balance

The fact that the fish population of a dam could be part of the pollution problem at first glance seems far-fetched. But on closer scrutiny, this is exactly the case in Hartbeespoort Dam where the composition of the fish population not so much contributes to pollution, but interferes with the dam’s ability to naturally maintain it’s ecological balance.

Dam access restricted for algae clean-up

Operations to clean up algae, floating debris and hyacinths where the Magalies River flows into the dam will necessitate restrictions on boat traffic in the area from the end of April. In a statement the Department of Water Affairs and Forestry (DWAF) said that algae has been a continuous problem in the Magalies River stretch of the dam and plans are being put in place to remove the algae.

Drywende eilande moet help red

Daar is min dinge so strelend op die oog as ‘n netjiese grasperk en as die grasperk grens aan water, is dit eens bekoorlik. Oewertuinbou deur ontwikkelaars en eienaars van private persele rondom die dam is kenmerkend van Hartbeespoort-dam en is waarskyn-lik een van die aantreklikhede wat mense lok om weer en weer terug te kom, ten spyte van die toestand van die water.

Restoring nature’s filters

For many people wetlands are just wasteland, a breeding place for mosquitoes and other .undesirable insects. Others, again, think of wetlands as marshes or swamps, like the Okavango swamps or the Greater St Lucia World Heritage wetlands. Read more ...

Wurms teen besoedeling

Vraag: “Hoe eet mens ‘n olifant?” Antwoord:
“Happie vir happie.”
Hierdie afgesaagde uitdrukking is tekenend van die proses wat nodig is om biomassa in Hartbeespoortdam te bestuur. Die taak is so omvangryk, die massa water so groot, die toestroming van besoedeling so onophoudelik en die biomassa wat bestuur moet word so moeilik om te beheer dat die meeste mense geneig sal wees om tou op te gooi nog voordat hulle begin het.

Combined effort needed to save Dam

Kormorant earlier reported on the various factors that contribute to the high rate of eutrofication (nutrient enrichment) of the rivers and dams in South Africa and how most of these impact on Hartbeespoort Dam.
Because Hartbeespoort is at the receiving end of most pollutant effluents, it is sometimes referred to as ‘the most polluted dam in the country’. Ironically, it is also probably the most popular, both as a residential area and as a recreation destination. This is due to its location close to the major population centres of Gauteng and its natural beauty. Read more ...

Cleaning ourselves into ruin

Modern man’s obsession with cleanliness is one of the major reasons why our dams and rivers are deteriorating at the present alarming rate. Add to that major sewage spills due to ill-maintained sewage works, uncontrolled squatting next to water sources, agricultural run-off and industrial and mining activity, and a very sombre picture emerges. Hartbeespoort Dam is on the receiving end of all of these. Read more ....
