Question NW1057 to the Minister of Water and Sanitation
09 May 2016 - NW1057
Baker, Ms TE to ask the Minister of Water and Sanitation
Has her department conducted an audit to assess the storage capacity of its dams; if not, why not; if so, (a) when was the specified audit conducted and (b) what did the results indicate?
Reply:
Yes, my Department conducted an audit to assess the storage capacity of its dams (referred to as capacity determination survey).
(a) The surveys are taken at the different times as each dam has its own return period for such survey to be conducted. This is largely due to the fact that these dams were commissioned at different times and also that severity of sediment accumulation will differ from dam site to dam site.
The attached Appendix A gives the storage audit of departmental dams. Column E of the spreadsheet gives a date when the capacity survey was done and Column N gives the return period.
(b) For results of storage audits please refer to Appendix A, Column K and L.
