Programme achieves +25% water saving<br />
Through an extensive partnership between<br />
Sasol, the Metsimaholo Local Municipality,<br />
Rand Water and a German development<br />
agency (GIZ) a 30% water saving was<br />
achieved in the greater Sasolburg area of the<br />
<strong>Free</strong> <strong>State</strong>.<br />
This was achieved through a water demand<br />
managment programme that started in<br />
2016, promoting water conservation and<br />
addressing water losses.<br />
Interventions followed a baseline study<br />
done by WRP engineers that focused on<br />
resources engineering, water conservation<br />
and water demand management, including<br />
lost revenues from water that could<br />
otherwise have been sold.<br />
Interventions included installation of meters<br />
and loggers, repairing of leaks on the main<br />
reticulation system, reconfiguration of<br />
the Harry Gwala reservoir and advanced<br />
pressure management.<br />
The baseline assessment further indicated<br />
that water leaks at hostels, schools and<br />
households should also be addressed.<br />
Aquatrips were installed at 28 township<br />
schools and permanent loggers, supported<br />
by a ZNet monitoring system, now ensures<br />
continuous monitoring. All this is supported<br />
by an extensive education and awareness<br />
programme in local communities that also<br />
make use of techniques such as virtual<br />
industrial theatre and puppet shows to<br />
enhance the learning experience.<br />
Basic leak repairs and retrofitting<br />
at 10 000 homes in Metsimaholo<br />
are done by local plumbers and<br />
water warriors – youth who<br />
received basic plumbing training.<br />
They focus on basic leak repairs<br />
such as in piping, taps and<br />
cisterns.
