Johannesburg mayor Mpho Phalatse invaded Sandton on Wednesday.
She went to Johannesburg’s premium hotel, Radisson Blu, and disconnected the water supply for non-payment of R14m.
The municipality said there was debt of more than R38bn owed to the City.
The biggest debt belonging to Sandton City, which owed R158m.
Before embarking on the #BuyaMthetho campaign (Bring back the law), the City issued notices of termination of services.
They advised clients to settle the outstanding amount or make arrangements for payments.
However, they didn’t take the notice seriously.
Phalatse added that the operations would continue throughout the city in the coming weeks.
