ASSOCIATIONS 59 Plastic pipes help SA through toughest drought in decades More plastic water pipes must be installed to help save water in the face of drought and water restrictions. By Southern African Plastic Pipe Manufacturers Association (SAPPMA) COULD THE PROBLEM HAVE BEEN AVOIDED? Whilst environmental factors such as El Niño and climate change are largely to blame for the country’s crippling water woes, the Southern African Plastic Pipe Manufacturers Association (SAPPMA) says that lacking and ageing water infrastructure have exacerbated the problem. “We first started sounding the alarm bells as early as 2010 over the lacking water infrastructure and the failure by local municipalities around the country to invest in upgrading and replacing their pipelines. We saw signs of severe water losses in distribution, caused by water leaks and wastage, many years before the crisis reached its full impact,” says Jan Venter, chairperson of SAPPMA — a non-profit association that represents more than 80% of the plastic pipe produced in South Africa and focuses its efforts on ensuring pipe systems that are leak-free and durable for long-term use. It also focuses on the rehabilitation of old pipelines. South Africa is currently in the grips of one of the worst droughts in decades, with five of the country’s provinces already declared drought disaster areas. The Western Cape, Northern and Eastern Cape, and Limpopo are the areas facing the greatest lack of water, with the Mother City counting down the days to the predicted Day Zero, when the province’s taps will run dry. South Africa’s pipelines were installed in the early 1950s and 1960s, and were manufactured from cement, asbestos, or steel. These old pipes have an economic lifespan of a maximum of 50 years and have long since corroded and disintegrated. This became evident many years ago as we started seeing an increase in water leaks and disrupted water supplies around the country. Millions of litres of treated water have been going lost every year,” he says. Venter confirms that the effects of the severe drought could have been negated had their calls for water infrastructure improvements been heeded earlier by the authorities. MUNICIPAL INVESTMENTS INTO IMPROVING WATER INFRASTRUCTURE Towards the end of 2017, the City of Cape Town announced plans to spend R8-billion on its water infrastructure over the next 10 years. According to Anic Smit, head of planning, design and projects of the City’s water reticulation services, the City has invested R1.2-billion on water engineering, refurbishment, and replacement infrastructure during the 2015/16 financial year. “Pipelines lie at the heart of South Africa’s infrastructure and must be replaced before they fail. Water distribution, waste disposal, irrigation, and telecommunications all rely on pipelines to function. However, the majority of The drought’s impact on pipe manufacturing businesses Cape Town-based OKE has reported a 20% drop in irrigation volumes. “Due to the lack of rain, farmers are not investing in new developments and are holding back www.plumbingafrica.co.za HDPE pipes are being used to replace old infrastructure.
