(a) At Heyshope pump-station there are 4 pump-sets of which 2 pump-sets are currently functional and in operation. At Geelhoutboom pump-station there are also 4 pump-sets of which 2 are in operation. These two pump-stations are operating in series together with long sections of gravitational transfers.
At Heyshope refurbishment of the booster motor at pump-set 1 is underway and procurement for the mechanical motor and control valve refurbishment is in progress. At Geelhoutboom line 1 the motor refurbishment is being completed and it is anticipated that it will be back in operation by January 2017. The other pump-set is awaiting the replacement of bearings which is in progress and should be back in operation by December 2016.
(b)(i) The volume of water transferred in 2015 was 27, 9 million cubic meters
(b)(ii) The volume of water transferred in 2016 is 43, 7 million cubic meters.
(c) In 2015 Heyshope had 3 out of 4 pump-sets in operation and 2 out of 4 in 2016. At Geelhoutboom 1 out of 4 was operational in 2015 and this improved to 2 out of 4 in 2016.
(d) Since the rectification work is not completed as yet, a final figure is not available as yet. However to date R97.7million was spent at these two pump-stations.
