FEATURE 51 consists of old steel and asbestos cement water pipes that were installed in the early 1960s or earlier. These pipes have a limited lifespan of no more than 50 years before they start to corrode, start to spring leaks and need to be replaced. “We could see from our members’ dwindling sales figures over the last few years, that no orders were being placed for new pipes, despite the fact that municipal budgets were allocated for upgrades and maintenance. Irregular expenditure of R13-billion wasn't accounted for in 2016 and 2017 in the Eastern Cape alone – making up almost half of the country's wasteful expenditure of the same year. As a result, plastic pipe manufacturers were forced to close down and a significant number of jobs were lost,” Venter says. By far the biggest culprits of wasting water are municipalities who do not repair leaks or fail to maintain their water pipelines. The Water Research Council recently conducted a survey of 132 municipalities in South Africa, which revealed that close to 40% of the country’s potable water was being lost as a result of leaks, incorrect metering and unauthorised consumption. By comparison, Australia (also classified as a water-scarce country) loses less than 10% per year. “The two main causes of water loss are corrosion and the poor joining of pipes. Not only does South Africa suffer financial losses of more than R7.2- billion/year, but we have lost a significant supply of water that we might never be able to replace again. Despite the good rains that have fallen in large parts of our country recently, we can still run out of water if we do not protect and look after what we have now as a matter of urgency. People can still live without electricity and as South Africans we have almost started to get used to regular power cuts. But nobody can live without water. Government must realise the seriousness of the situation and plan for the generations to come through installing the correct plastic pipes that are capable of meeting the infrastructure needs of a growing South African population,” Venter urges. He adds that although the minister’s plans for water restrictions, drought measures and recycling of water are important, she fails to address the real cause of the country’s water crisis. Additionally, it is important to remember that plastic pipes are not just used to supply water to towns, cities and communities, but that almost all infrastructure relies on these pipes to improve people’s lives and enable day-to-day, modern living. Electricity, gas and telecommunication supply are all possible thanks to the use and installation of plastic pipes. February 2020 Volume 25 I Number 12 In South Africa and the rest of the world, plastic pipes are the material of choice to replace ageing pipes and infrastructure as they do not corrode or perish, and the joints are leakproof if installed correctly. They are available in various diameters and wall thicknesses, offer a much longer lifespan, are cheaper and more efficient to install and offer significant savings to municipalities thanks to them offering less friction, resulting in lower pumping costs, less maintenance and fewer interruptions. SAPPMA held its annual AGM in November. SAPPMA CEO, Jan Venter. In conclusion “We urge municipalities and the water engineers writing the specifications for the pipeline upgrades to specify in their planning documents that only HDPE and PVC pipes bearing the SAPPMA logo will be installed. Any other pipe will be untested, runs the risk of being inferior quality and can put entire pipelines at risk. Plastic pipes that don’t clearly bear and display the SAPPMA logo are likely to contain dangerous heavy metals such as lead and cadmium, or recyclate which could leach into the pipes and will almost certainly not deliver the longevity or performance that is required. “We hope that the current crisis will act as a much-needed wake-up call to our leaders and that they will recognise the need to appoint competent, qualified technical personnel at national, provincial and municipal level. Decision-makers need to be educated and encouraged to invest in buying the best quality products they can afford and commit to a disciplined maintenance regime for pipe systems. We can turn the situation around if we work together and they are willing to listen to advice from the industry. SAPPMA’s door is always open and we are offering our assistance in any way needed. Together we can. Thuma mina!” concludes Venter.
