Government is the biggest polluter of water in SA – AfriForum
23 September 2015
The civil rights organisation AfriForum says according to the Green Drop Report 2013 (GD 2013), Government is the biggest polluter of water in South Africa. “Government is discharging approximately 3 642 Ml/day (million litres per day) of sewage effluent that does not comply with safety standards into our rivers and dams. That means that 74% of wastewater treatment facilities are unlawfully polluting our water, which is criminal,” said Julius Kleynhans, Head of Environmental Affairs at AfriForum.
AfriForum compiled a report which focused on the biggest culprits in each province, indicating the snowball effect caused by the pollution. “Our drinking water is usually subtracted from a river/dam and distributed by a municipality. The Vaal Dam is a good example of the provision of water to Gauteng’s metros. The effluent generated in that municipal area must be cleaned and discharged at the regulated standard to ensure a clean and healthy aquatic system, irrigation water and drinking water for the municipalities using the source downstream,’ said Kleynhans.
Wastewater services delivery is performed by one hundred and fifty two (152) water services authorities in South Africa via an infrastructure network comprising of 831 wastewater collector and treatment systems. A total operational flow of 4910 Ml/day is received at the 831 treatment facilities, which have a collective hydraulic design capacity of approximately 5645 Ml/day. This means that 87% of the existing design capacity is accounted for by the current operational flows, leaving a theoretical surplus of 13% as ‘available’ capacity for future demand. “These facts can be questioned because many individual plants have no surplus and run at full capacity. The number of manholes discharging raw sewage into storm water drains, streams, rivers and dams also raises concerns about the transparency and accuracy of the Green Drop Report results due to the fact that some wastewater treatment works may not receive the full amount of sewage in their service areas,” Kleynhans said.
“248 systems have been issued Purple Drops in 2013 for receiving <30% and thereby earning the undesirable status of “systems in crisis”. These 248 “purple drops” or systems in crisis, as phrased in the Executive Summary of the GD 2013, were however (unfortunately) not mentioned by name,” Kleynhans added.
