The Department of Water and Sanitation (DWS) has given the City of Tshwane 60 days from 31 March to say what it plans to do to fix collapsing sewage treatment plants.<\/p>\n
The department\u2019s 2025 Green Drop Report reveals a sanitation system in steep decline, placing communities and ecosystems at risk.<\/p>\n

\nSA\u2019s water crisis is a management, not just infrastructure, problem<\/p>\n
Scores of 90% are considered excellent, while scores below 31% are rated critical and trigger regulatory intervention. Once a strong performer with a score of 82% in 2013, Tshwane\u2019s score has plunged to under 34%, placing the metro firmly in the \u201cpoor performance\u201d category.<\/p>\n
As a result, the department has placed the municipality under regulatory surveillance in accordance with the Water Services Act, a status that signifies a \u201csystemic operational, governance and compliance failure\u201d requiring urgent stabilisation.<\/p>\n
The city has to submit a detailed plan outlining specific measures and time-bound milestones to restore functionality and compliance.<\/p>\n
The report, published by the department on 31 March 2026, is the country\u2019s main audit of wastewater services. It evaluates operational capacity, environmental performance, financial management, technical skills and compliance with effluent and sludge standards.<\/p>\n
Tarryn Johnston, a water activist and director of environmental services firm Living Wisdom Strategic Solutions, says: \u201cThe score is not a revelation; it is an overdue acknowledgement of a collapse that has been visible, measurable, and escalating in real time.\u201d<\/p>\n
Six treatment plants disqualified<\/p>\n
The report reveals an alarming average microbiological compliance score of just 4% for Tshwane\u2019s sewage treatment works.<\/p>\n
None of the 16 systems met the satisfactory threshold, and 15 fell below the critical 30% level, putting public health, rivers, groundwater, ecosystems and agriculture at risk.<\/p>\n

Six of Tshwane\u2019s 16 wastewater treatment works had a general score of 30% or below.<\/p>\n
Bronkhorstspruit (Godrich) dropped from 61% in 2021 to 30%, Ekangala from 55% to just under 23%, Rooiwal Eastern Works fell from 69% to 30%, Rooiwal Northern Works from 67% to under 24%, Rietgat dropped from 63% to 28.5% and Klipgat stayed more or less the same, at 30% compared to 29%.<\/p>\n
These plants triggered penalties due to exceeding capacity, persistent effluent failures and non-compliance with regulatory directives.<\/p>\n
Eight other treatment works scored between 30% and 50%, all in decline since 2021.<\/p>\n
Zeekoegat fell from 61% to 44%, Sunderland Ridge from 66% to 35%, Babelegi from 56% to 35%, Baviaanspoort from 57% to just under 35%, Sandspruit from 54% to just under 35%, Rayton from 49% to 32.5%, Refilwe from 53% to just under 32%, and Temba from 64% to about 32%.<\/p>\n
The department said a criminal case has been lodged with the National Prosecuting Authority (NPA) for prosecution and an investigation involving the South African Police Service (SAPS) is under way.<\/p>\n

Capacity and other challenges<\/p>\n
Tshwane reported using only 103 040 kilolitres per day (kL\/day) of its 506 400 kL\/day wastewater treatment capacity.<\/p>\n
But this is misleading, as 14 of the 16 plants did not submit flow data, and much sewage may be leaking or spilling into the environment before reaching treatment works.<\/p>\n

Among the few plants that did submit data, Daspoort is operating under severe strain at more than double its design capacity.<\/p>\n
The City of Tshwane was flagged for poor management, which complicates risk assessment and planning, as it was unable to provide the total length of its sewer network.<\/p>\n
Long-term underinvestment, theft and vandalism have contributed to recurring pollution incidents. Engineering capacity is \u201csignificantly below\u201d requirements, with less than three qualified staff per plant on average, compared to more than eight in Johannesburg.<\/p>\n
Operational staff training levels are among the lowest in the province.<\/p>\n
Financial mismanagement has exacerbated the situation, with the metro underspending its operations and maintenance budget by more than 20%.<\/p>\n
The DWS has classified Tshwane as a \u201cregulatory concern\u201d, noting that past investment has not translated into improved performance or accountability.<\/p>\n

Calls for systemic intervention and city plans<\/p>\n
Johnston said reversing the decline requires stabilising failing plants, rehabilitating key treatment processes, restoring technical expertise, protecting upstream infrastructure, enforcing compliance and coordinating action across the river systems.<\/p>\n

Without such interventions, she warned of serious public health risks, environmental degradation and rising economic costs linked to water treatment, agriculture and long-term water security.<\/p>\n
The City of Tshwane acknowledged receipt of our questions sent a week ago but has not responded to GroundUp.<\/p>\n
However, Tshwane\u2019s draft 2026\/27 Integrated Development Plan (IDP) strives for 90% Green Drop compliance.<\/p>\n
Initiatives include fast-tracking the Rooiwal Wastewater Treatment Works upgrade, maintaining and refurbishing critical assets, expanding the \u201cWar on Leaks\u201d programme, and building in-house technical capacity.<\/p>\n
The metro\u2019s water and sanitation budget will rise from R721 million in 2026\/27 to R1.37 billion by 2028\/29.<\/p>\n
Key allocations cover Rooiwal, Ekangala, Sunderland Ridge, and Baviaanspoort wastewater treatment works, as well as sewer replacement and pump station upgrades.<\/p>\n

Long-term projects include a R530 million full upgrade of Rooiwal, R759 million for Magalies and Klipdrift plants, and R8.5 billion for a new wastewater treatment system started in 2015 and expected to be completed in 2029. But, 11 years later, it still has not moved beyond feasibility studies.<\/p>\n
