Saint-Gobain Gyproc’s plant in Brakpan, Gauteng, has reduced its reliance on municipal water by over 30% in the last two years.
South Africa is a water-scarce nation, prompting several Saint-Gobain operations, including the Brakpan plant, to critically review water consumption patterns and levels. With pressure to reduce consumption without negatively affecting production, mandatory water-reduction requirements would have a significant impact on production.
After assessing different options, management decided to reduce reliance on municipal water by sinking a borehole and building a two-million-litre capacity reservoir.
“The project was a big investment, but has proven its worth,” says Kurt Van Schoor, continuous improvement manager. “The system works well and our production will be secure in most emergencies. We have no firefighting concerns and, more importantly, there are clear financial benefits.”
Seventy-five per cent of the reservoir is dedicated to the production, while the other quarter is for firefighting purposes only. It is kept to maximum capacity via a combination of municipal water, rainwater and borehole water. A physical barrier makes sure that the firefighting water cannot be used for production.
As a result, the Brakpan plant self-supplies at least 30% of its water requirements, reducing its reliance on municipal water and ensuring continuous production.
