Currently, the town of Mossel Bay in South Africa is experiencing its worst drought in 132 years. Wolwedans Dam, the town’s main water source, is now less than 12% full.
In an attempt to support the town, our Mossel Bay factory in South Africa cut its water usage by 54% between October 2009 and May 2010.
With new equipment costing around ZAR 1.2 million (over CHF 175 000), the factory’s water usage was cut from 25 000 to 11 500 kilolitres per month between October 2009 and May 2010. Water usage per tonne of product produced was reduced from 17 kilolitres per tonne of product in 2009 to 8.2 kilolitres per tonne produced in 2010.
The water-saving project consists of a four-pronged approach including an awareness campaign, measurement of water usage, an action plan and continuous improvement and advertising of the results. Under the initiative, a water usage measurement system monitors water in the various sections of the plant and corrective action is undertaken when necessary.
The significant saving is due to the recovery and use of condensate from the evaporation process, which is recovered and used for various industrial processes on-site. In addition, several immediate water-saving measures were introduced, such as shortening automated wash times and modifying hosepipe nozzles to reduce water flow, and employees were also advised on water-saving measures at home.
Alderlady Marie Ferreira, the Executive of Mayor of Mossel Bay, praised the drive to save water. She said: “I am absolutely delighted at the water savings of more than 50% achieved by the factory and the way that responsible water management has been made an integral part of their operations. The Company has demonstrated what responsible corporate citizenship is.”
