Is the tap water safe in Ntabankulu?
The government’s latest official rating puts all 7 drinking-water systems of the Alfred Nzo District Municipality at low or medium risk. It’s the Department of Water and Sanitation’s Blue Drop risk assessment of 2024, published in March 2026.
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.
Water in Ntabankulu is the responsibility of the Alfred Nzo District Municipality, so the figures here are for all the district’s systems and works, not only those in Ntabankulu. The district also supplies Matatiele, Umzimvubu and Winnie Madikizela-Mandela.

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 Alfred Nzo District 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, 4 of the 6 works the district runs were in a critical state.
| Works | Score | Category | Releases into |
|---|---|---|---|
| Bizana | 12.9% | Critical state | Mtentu River |
| Cedarville | 28.5% | Critical state | Wetland |
| Matatielle | 22.9% | Critical state | Wetland |
| Mount Ayliff | 35.7% | Very poor | Mzintlava Watercourse |
| Mount Frere | 27.5% | Critical state | Mzimvubu River |
| Ntabankulu | 56.6% | Average | Caba |
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 Alfred Nzo District Municipality’s management of water losses at medium risk (53.3%; below 50% is low risk, 90% or more critical). In 2023/24, 100% 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 low (estimated). Its report counts more than 40% as extremely poor, and less than 10% as excellent.
