South Africa’s southern Nelson Mandela Bay municipality, which includes the coastal city of Gqeberha, is facing water outages after the levels of a major dam in the Eastern Cape province dropped too low for extraction.

The Impofu Dam, the second-biggest dam supplying the municipality when full, has hit “day zero” and can no longer supply residents, water availability and usage statistics shared on the municipality’s Twitter account showed. The Churchill Dam was currently just over 9% full, with an estimated 11 days of water left, while the Loerie dam was at 44% capacity, with 37 days of water remaining, the municipality’s data showed.
