Expert input
Helen Hulett , general manager of Talbot & Talbot ’ s Water Risk & Strategy Business Unit , offers her input on wastewater treatment .
Q : What are the main challenges of wastewater treatment in South Africa ?
TT : The primary challenge to wastewater treatment in South Africa is the lack of recognition of the financial value of wastewater , a consequence of multiple factors , including : 1 . A poor understanding of the resources captured within wastewater streams . This not only includes the actual water , which once treated is often of a better quality than the original supply , but can also include others such as energy and input materials . Consequently , the treatment of wastewater can provide significant financial savings to an organisation .
2 . A water price that is not reflective of the true cost and importance of water , making it difficult for industry to equate the lost opportunity of discharging wastewater compared with treating and reusing the resource and avoiding further withdraw and non-compliances .

Q : Please comment on SA ’ s present wastewater landscape
TT : South Africa receives on average 450mm rainfall a year compared to a global average of 870mm , making us the world ’ s 30th driest country . Despite this , we have historically managed water very poorly . However , the growing water supply challenges faced by the country over recent years is driving change , and the next few years will see a significant transformation in the way water is viewed , managed and regulated . u
