Regulatory Comments 2011 :
The Blue Drop performance of Kheis Local Municipality remained constant. The Department was, however, presented with evidence to confirm that the water safety planning process is underway in each of the supply systems. The DWA trusts that risks identified in this process and adaptations to both monitoring programmes and treatment processes will result in future performance improvements. The WSA is now encouraged to take ownership of the process by addressing site specific risks. Without data to confirm that a full set of SANS 241 analyses had been conducted in each of the supply systems, the revised monitoring programmes cannot be deemed appropriate. Information will be also required in future to confirm the risks that apply to the various raw water sources that are treated. DWA could not confidently confirm the excellent drinking water quality recorded in most of the supply systems because the scarcity of data submitted did not allow an statistically reliable compliance calculation. Monitoring should be maintained throughout the year, and the frequency of sampling should correspond to the risk-defined monitoring programmes. Operational monitoring was also found to be inconsistent and not aligned to the registered programmes, and it was clear from the site inspections that a number of instruments were not functional at the time of the inspection, resulting in a lack of credible data for process control. Available data shows that drinking water within the Boegoeberg/Brandboom and Topline supply systems poses an unacceptable risk to public health due to microbiological failures. While the WSA is required to improve disinfection, overall monitoring should also increase to allow a more accurate assessment of the quality of water in all the supply systems. Not all Process Controllers were classified according Regulation 2834 (to be replaced by Regulation 17). While the WSA addresses this non-compliance, process controlling staff should also be confirmed as competent and sufficient to maintain the treatment process at the various plants. Recording of daily activities in logbooks should furthermore be undertaken at each of the treatment plants. To ensure improved drinking water quality management, Kheis Local Municipality management is required to provide leadership and funding for the required asset management activities. Detailed process audits are required at each of the treatment systems, the asset register should be updated to include assets of the Gariep supply systems, and the WSA is advised to confirm the accuracy of information provided related to financial planning and expenditure. Officials also had difficulty providing confirmed data regarding the design and actual operating capacities of the various treatment systems; updated information is required to be readily available for day-to-day operational business and Blue Drop assessments.
