(1) My Department has assisted the Kannaland Local Municipality to diversify its supply sources to ensure long-term water security. By supporting the development of groundwater, my Department ensured that the town is no longer reliant on surface water flow and storage; which is highly vulnerable in times of drought. Conjunctive management of groundwater and surface water sources is now possible. This provides new possibilities to optimise the use of both surface and groundwater storage seasonally and during periods of drought.
(2) Yes, additional boreholes were drilled in the 2014-15 financial year with no additional boreholes drilled since 01 July 2015.

R14, 5 million was spent to drill boreholes |
The average expenditure for each borehole was R600 000.00 |
The infrastructure was funded through Regional Bulk Infrastructure Grant (RBIG). |
(aa)(bbb) How many boreholes were upgraded |
No existing boreholes were upgraded since 01 July 2015 because sufficient groundwater has been developed to bridge the drought in the short-term. |

(3) Yes, the yields are economically viable. The yields need to be refined based on long-term testing /operation of the wellfield. Operational for one year, which commenced in April 2015.
(4)(a) Yes, the construction of a new dam is being considered.
(4)(b) The completion of implementation readiness study subsequent to feasibility study will assist to finalise the cost, sources of funding, and the timelines. The feasibility study is at final stage.
