Green Drop Progress Report

The 2014 Green Drop Progress Report, published by GreenCape, provides a national overview of wastewater treatment performance in South Africa. It utilizes the Progress Assessment Tool (PAT) to track the Cumulative Risk Rating (CRR) of municipal, public, and private wastewater treatment plants, highlighting a general trend of increasing risk across the sector between 2013 and 2014.

• The national risk profile for wastewater treatment plants showed a decline in performance in 2014, with the average CRR increasing from 12.2 in 2013 to 13.4 in 2014. The average percentage deviation from the maximum CRR also rose from 65.4% in 2013 to 71.7% in 2014.
• A significant number of municipal plants are operating at high or critical risk levels. Specifically, 259 plants are in high risk positions and 212 are in critical risk positions, while the number of low-risk plants decreased from 199 to 135.
• Out of the total municipal plants assessed, 508 plants showed a digression in risk ratios, while 198 plants showed progress by moving to lower risk positions and 118 maintained their status.
• The 2013 results for different sectors showed stark contrasts: 80% of the five participating privately owned systems achieved Green Drop Certification ('excellence' space), whereas 86% of the 121 systems assessed for the Department of Public Works were in a 'critical state' and received Purple Drop status.
• The Department of Environment's Kruger National Park services were assessed across 13 systems, all of which used ponds and reed bed treatment. 84.6% of these were in an 'average state', and 15.4% were in a 'poor state', with none in a 'critical state'.
• The Cumulative Risk Rating (CRR) is calculated based on four weighted factors: Design Capacity (A), Operational flow exceedance (B), Number of non-compliance trends in effluent quality (C), and Compliance regarding technical skills (D).
