• We are aware that water supply to the IVRS will be
impacted by the planned six-month closure of the
Lesotho Highlands Tunnel for maintenance work.
The total annual supply to the IVRS is projected to be
met by increasing supply prior to the shutdown and
again following completion of the work. The outage
of the tunnel is not projected to result in supply risk
if conducted in the planned timeframe.
River water quality
Enabling an adequate quality of water supplied
from the IVRS
• The quality of water to SO as supplied from the
Grootdraai Dam catchment remained within an
acceptable range; and
• Sasol supported a partnership with the Water Research
Commission and Rhodes University to assess long-term
water quality trends in the Grootdraai Dam catchment.
The assessment identified and prioritised opportunities
to manage water quality in the catchment.
Chemical oxygen demand (COD) on wastewater
discharges
• Aligned with information reported on the Department
of Water and Sanitation’s Integrated Regulatory
Information System (IRIS) we report on the SEO
barrage effluent discharge and SOs U53 discharge; and

• Work to maintain or achieve Green Drop status remains on track at both SO and SEO.
• We continued supporting multi-stakeholder catchment assessments to identify
opportunities to advance management of the Upper Vaal including the Waterval catchment.
– The Grootdraai dam water quality study in partnership with Rhodes University and the
Water Research Commission was completed. The project has successfully established
a framework for ongoing improvement in water management practices within the
Grootdraai catchment area; and
– SO signed a memorandum of understanding with Rand Water to
investigate the feasibility for an offtake of treated effluent from the Sedibeng works
as an alternative source to river water. A feasible solution has not been identified yet,
but we remain open to consider this option should a feasible prospect be identified.

The Sasol Energy Business approved the methodology to develop short-term (Phase 1) and
long-term (Phase 2) water targets. The Phase 1 targets for Sasol Energy’s three largest water
users being SO, SEO and Mining are being implemented.
