While there is currently an urgent drive to conserve water in South Africa, much of the country’s usable water is lost through leaks in municipal pipeline networks as well as through leaking sewers and storm water pipelines. Conventional methods of repair involve digging up old pipelines and replacing them. However, in highly dense urban and peri-urban areas, this is often an almost impossible task, as it involves major and costly disruptions to other infrastructure along the route of the pipeline.

AEGIONSAapril2018JScholtzAegion South Africa circumvents this problem through the application of its trenchless technology. This technology achieves permanent, stronger and safer solutions for the rehabilitation of pipeline infrastructure, according to Johann Scholtz, General Manager of Aegion South Africa.

“Cured-In-Place Pipe (CIPP) pipeline rehabilitation presents a cost-effective and extremely fast method of restoring pipeline integrity. This replaces and is vastly superior from a technology and cost perspective to conventional ‘dig and repair’ methods of pipeline rehabilitation. Aegion-branded Insituform is especially suited to provide long-lasting quality solutions in the execution of CIPP rehabilitation projects,” he says.

“Typically, rehabilitating a pipeline under a major urban highway would rate as a highly disruptive dig and repair job. To dig up a pipeline such as this would traditionally involve some six weeks of huge cost and inconvenience to thousands of motorists,” adds Aegion’s Craig Bennett.

“With Insituform, we are able to complete a project such as this in just four days - with no inconvenience to the road authorities or the public. Speaking from my personal experience, Insituform’s InsituMain product is the leading CIPP technology on the market as the lining it produces is both thinner and stronger, meaning that projects such as the one described can be far more quickly and effectively completed.”

Scholtz says that Aegion South Africa’s partnership with Robor South Africa, which owns 40% of the company, allows Aegion to access its range of longitudinally-welded steel tube and pipe as well as a range of steel pipe and customised conveyance pipe solutions, providing complete piping solutions to the infrastructure market. Through its international principle, the company has access to proprietary technologies and services for the corrosion protection of industrial pipelines and for rehabilitating and strengthening sewer, water and mining pipeline infrastructure.

In addition, Aegion South Africa has local experience and expertise in the field of hydro-transportation. This involves pumping solids through the pipeline in a fluid medium and is of particular application in the mining industry, an example being the pumping of high specific-gravity paste tailings. Other capabilities include pipeline rehabilitation, services to new pipelines, the restoration of the pipeline integrity, cathodic protection, structural reinforcement and refinery maintenance.
