Is the tap water safe in Ekurhuleni?

The government’s latest official rating puts the drinking-water system in Ekurhuleni at low risk. It’s the Department of Water and Sanitation’s Blue Drop risk assessment of 2024, published in March 2026. Ekurhuleni includes Germiston, Benoni, Boksburg, Kempton Park, Springs, Brakpan, Alberton, Edenvale, Tembisa and Nigel.

This is the government’s latest official assessment (published in March 2026, on data from July 2023 to June 2024), not a live test of your tap water or a guarantee that it’s safe.

Each drinking-water system, 2024

SystemRisk
EkurhuleniLow 28.1%

The department’s risk rating for each system, from its Blue Drop risk assessment of 2024 (data from July 2023 to June 2024). Below 50% is low risk; 90% or more is critical.

What the ratings mean

The Department of Water and Sanitation rates each drinking-water system’s risk from four things: the size of its treatment works and how close it runs to capacity (35% of the rating), whether its water met the national drinking-water standard, SANS 241, in tests, and whether enough tests were done (35%), the skills of its staff (20%), and whether it has a water safety plan (10%).

The rating is a share of the worst possible score, so higher is worse: below 50% is low risk, 50% to under 70% medium, 70% to under 90% high, and 90% or more critical. It describes how a system was run and tested over a year, not the water in your glass today.

Your water today

For the water in your tap today, ask the Ekurhuleni Metropolitan Municipality. It’s responsible for the water here and issues boil-water notices. If it issues one, follow it.

Sewage works

Sewage works don’t supply your tap, but what they release flows into rivers and dams, and the department’s Green Drop report links poorly treated sewage to risks for public health downstream. In its audit for 2024, none of the 17 works in Ekurhuleni were in a critical state.

Green Drop audit for 2024 (July 2023 to June 2024), published in March 2026. The department’s categories: 90% or more is excellent, 80% good, 50% average, 31% very poor, and below 31% a critical state. Higher is better. “Releases into” is where the works discharges, as the report prints it.

Water losses

The department’s No Drop assessment of 2025 rates the Ekurhuleni Metropolitan Municipality’s management of water losses at low risk (35.0%; below 50% is low risk, 90% or more critical). In 2023/24, 30% of the water it put into its pipes was never billed: lost to leaks and bursts, taken illegally, or used without a bill. The department rates the accuracy of those figures as high (metered). Its report counts more than 40% as extremely poor, and less than 10% as excellent.

The last full audit: Blue Drop scores, 2023 (1 system)

The full Blue Drop audit of July 2021 to June 2022, published in 2023. Higher is better: 95% or more is excellent, and below 31% a critical state. Systems may be named differently from 2024.
