www.waterafrica.co.za service provider to efficiently operate any pumping and water treatment process include reduced risks, guaranteed compliance with the relevant standards, a reduction in utility costs, and increased water security. “Despite the fact that these types of operations can be quite complex, a capable consultant can reduce a client’s water bills by between 30% and 50%. With resource certainty being a significant challenge for businesses today, finding ways of becoming less reliant on municipal supply is an important issue for every business,” he says. “Depending on the client’s situation, we are often able to install and operate a water treatment plant (using either groundwater or wastewater) and sell a client SANS- compliant potable water at a cheaper rate than they can buy from the current supplier,” concludes Fahy.  innovations Water and Sanitation if they are using groundwater. Also, if the water is going to be consumed by the public, they need to be classified as a ‘Water Services Intermediary’ — this is a requirement in Cape Town, specifically. They also have to implement monitoring and testing programmes to ensure that the quality of the water is maintained.” The good news, according to Fahy, is that this responsibility can be outsourced to a service provider that can help to make it financially viable. “A competent service provider is able to efficiently operate any pumping and water treatment processes that one has on site and conduct regular testing, both for providing the appropriate certificates and to proactively manage any water quality challenges.” Fahy adds that the benefits to a business partnering with a specialist The common misconception about borehole water is that it is pure, filtered water, but the fact is that there is a host of factors that could affect the quality, making it unfit for human consumption, food production and, in some cases, even industrial applications. “The common misconception about borehole water is that it is pure, filtered water, but the fact is that there is a host of factors that could affect the quality, making it unfit for human consumption, food production and, in some cases, even industrial applications. Underground water often has a high mineral content, and toxins such as pesticides can filter through to underground reservoirs,” says Fahy. “And then, of course, there’s the threat of microbial content like bacteria and viruses such as E. coli,” he adds. He explains that underground water can also have high iron or calcium content, which can result in borehole water not only being unfit for human consumption, but also potentially detrimental to equipment. “Therefore, if a business intends to start using underground water for any large-scale operation, it is likely that a water treatment plant will be necessary on site.” As such, he points out that many of the properties located above underground water sources that enquire about the possibility of pumping borehole water to their operations, should note that this is more complex than one may expect. Fahy says that a treatment plant is not a one-size-fits-all solution. “Each underground water source has a unique mineral and/or impurity content, and the treatment plant will need to be optimised accordingly. It requires a dedicated team to continuously conduct quality tests and run the treatment plant as efficiently as possible in order to ensure the best possible return on investment.” In addition, with many of the businesses considering this option, working in the food production and retail industries, it is also important to take into account that a number of regulations on water quality would apply, in compliance with SANS 241. “Businesses are taking on a substantial responsibility when they start using underground water for applications that might also involve human consumption. It will therefore be necessary to conduct regular testing on the quality of one’s processed water and be able to provide proof to the relevant parties that the water is up to standard. This means that one needs the services of a certified laboratory as well.” “Businesses should know that they need to apply for a water use licence with the Department of Partnering with a specialist service provider to efficiently operate any pumping and water treatment process means reduced risks and compliance with the relevant standards.
