Sembcorp Siza Drought Update

Sembcorp Siza Drought Update

Date: 2015-10-16
Since drought hit the province in September 2014 and the continued deterioration of the Hazelmere Dam supply level, Sembcorp Siza Water embarked on various initiatives to augment water supply. These included requiring customers to voluntarily reduce water consumption, the drilling of boreholes, recycling water, etc.

Mr. Nicky Misra, Project Manager said that "the company had undertaken a feasibility study with regard to locating potential borehole sites. The company has since successfully drilled and commissioned 7 boreholes with appropriate on site treatment, to ensure that water from the boreholes complies with the SANS 241:11, potable water standards. Sembcorp Siza Water intends commissioning additional boreholes to reduce the reliance on the Hazelmere supply. Since these boreholes have been commissioned together with a reduction of consumption by our customers we have achieved approximately a 35% reduction.

Sembcorp Siza Water will soon launch the recycled water plant which will have the capacity to produces 5 million litres of water per day. This plant will effectively supply 40% of the daily usage of Sembcorp's concession area.

The recycled water has been utilized since December 2014 where customers have been using it to fill swimming pools, for construction purposes, firefighting and irrigation.

Mr. Koos Duvenhage, Process and Quality Supervisor said "this is the future" and also mentioned that "the value of reuse water is very high and plays a major role in the construction industry and ensured minimal impact to the industry and local economy. The quality of the Reuse/Recycled water has been tested and is in compliance with SANS 214:11 for potable water drinking standards.

Mr Shyam Misra, Managing Director of Sembcorp Siza Water stated; "A rigorous quality monitoring system is in place to ensure that the water quality meets the stringent standards as most boreholes, if not all, provide water that is not safe for human consumption. The company will be commissioning additional boreholes with appropriate treatment to further reduce the draw down from Hazelmere Dam as well as a further recycling plant in Shakaskraal. We thank all our customers who assisted in playing their role in saving water".

Misra added that "we would also like to encourage our customers to continue being water wise as the Hazelmere Dam remains critically low and is currently at under 30% at 29.35 %." Mr Misra also wished to thank the management and staff of Sembcorp Siza Water for their outstanding efforts and contribution made in managing the drought.
