Ageing water infrastructure in cities throughout Gauteng, South Africa, is leading to a loss of millions of litres of potable water, while sewerage leaks silently contaminate waterways and ground water.

With thousands of pipelines already well over the 50-year mark and equally many over 100-year old, failures are becoming commonplace and specialised pipe-laying companies like Brakpan-based Gokor Construction are increasingly being called to find ways of replacing the pipes under layers of underground infrastructure and below houses, hospitals, roadways and buildings.

Hammerhead Pipe Bursting ELB Equipment 01 2018

Gokor Construction is one of the only specialised pipe laying companies in the region that can undertake large-scale pipe replacements using pipe-bursting technology that allows special tooling to be passed through and burst existing pipelines, while simultaneously pulling-in a new (often larger diameter pipe behind it). In this way, up to 170 m of pipeline can be replaced in two hours without digging trenches or interfering with above-ground or buried infrastructure. This is very much soil dependable as to the time period.

According to Gokor Construction owner, Jan Bouwer, the company purchased a purpose-built Hammerhead HG12 and Hydroguide pipe-bursting system from local distributor and specialist, ELB Equipment, precisely to undertake this type of specialised pipe-replacement work for Gauteng’s municipalities.

“Throughout Gauteng we have built our towns and suburbs over these buried pipelines and now it is mostly impossible to manually dig trenches and repair or replace pipes. As a result, a complete pipeline failure means that either the area gets dug-up or the place floods in water or sewerage. With our solution that does not have to happen as we simply dig entry and exit pits, as well as inspection pits and pull new pipes through without unsettling the ground,” explains Bouwer.

“In places like Tembisa we were even able to replace a 70 m stretch in 38 minutes and the entire 170 m pipelines in just two hours. In cases like this it ensures the municipality is able to effect speedy upgrades and it saves residents the inconvenience of digging up their properties, as well as providing a quick replacement service for water and sanitation,” says Bouwer.

ELB Equipment product manager, Phillip Mc Callum, explains that the Hammerhead solution is most suited to urban work and allows crews to work in confined and heavily built-up areas. With round-the-clock support from ELB Equipment, the machine is able to work for protracted periods of time reliably and with minimum disruption, which is especially important on urgent pipeline replacement projects.
