• AverageBlueDropScore:  65.3%

• AverageDWQCompliance:  95.1%

Regulatory Impression: The DWQ management performance of Ukhahlamba District Municipality is satisfactory;  however,  improvement is required to be adequately prepared for DWQ related incidents. Process Controlling and management at all the water treatment works is the primary concern, along with disinfection optimisation, which is required in the towns of Burgersdorp, Lady Grey, Maclear, Sterkspruit and Rhodes.  Laboratory services from accredited providers will further improve the BlueDrop scores.  With attention to these points, the water supply systems should be obtaining Blue Drop status during the next round of assessments.

Regulatory Impression:  The Joe Gqabi Local Municipality has shown good progress with the performance of their wastewater treatment plants where the risk rating of nine of their plants has reduced. Seven plants are categorised as medium risk plants and four plants as high risk plants. Key risk parameters include the lack of influent monitoring (only two plants monitor influent flowrates) and poor effluent compliance. Non compliance with R2834 with regard to the operating and maintenance staff also increases the risk of the plant.

The risk ratings of the Maclear and Ugie oxidation ponds has reduced due to the evaporation of the final effluent rather than discharge to the environment which reduces the risk of the plant. The plants are now categorised as low risk. Key risk parameters are the lack of information regarding the operating capacity and non compliance with R2834 for operating and maintenance staff. Although monitoring is not a requirement for calculating the risk of oxidation ponds that do not discharge effluent into the environment, it is recommended to enable the treatment performance of the wastewater treatment works to be monitored. Of concern however is that three plants have increased their risk rating and are now categorised as critical risk plants due to lack of influent monitoring information and the lack of effluent compliance monitoring. The lack of information with regard to the operating capacity and design capacity and the compliance of the final effluent render the management of the treatment process difficult to monitor and optimise and the reduction of the risk rating.

The Municipality is to be commended for the number of upgrading and refurbishment interventions already implemented and the Business Plans developed to request funding for additional refurbishment and upgrading projects. This demonstrates a proactive approach to ensuring optimal treatment performance and will result in a reduction in the risk rating. The Department encourages the Joe Gqabi Local Municipality to develop a Green Drop Implementation Plan and W2RAP for to facilitate the implementation of risk based interventions to improve compliance and to reduce the risk rating of the plants. Improved compliance with the Green Drop criteria and a reduction of the risk rating will require management support and the appropriate allocation of resources for implementation of corrective actions.  (Ref 7)

Risk Trend Analysis

2010/11

Regulatory Impression:  This is the first Green Drop assessment of Joe Gcabi District Municipality and it confirms that wastewater management is not up to standard across the entire jurisdiction area. While this municipality gave great attention to improve the state of drinking water quality management, the same is yet to be seen in wastewater. It should be noted that wastewater treatment is the first risk barrier to safe drinking water supply, and therefore the municipality is required to give similar attention to wastewater. The municipality scored good in the areas of Process Control and Bylaws which is laudable. However it is important that urgent turn-around planning is done to ensure further damage to the environment (due to under-performing wastewater treatment) is minimised and ultimately stopped. While effluent quality compliance is an area of great concern, the condition of Burgersdorp and Jamestown should be given special attention since both these wastewater treatment works are determined to be within the critical risk category (scored 100% maximum possible risk regarding it cumulative risk rating). A recommended start would be to put systems in place to obtain operational information which would allow management to be based upon the actual situation. (Ref 5)

2009

• Average Green Drop Score: 3%

Regulatory Impression: The WWQ management performance of the Ukhahlamba District Municipality, as a whole, is very poor. Substantial improvement is required in the all areas of WW Management. (Ref 3)
