The department of water and sanitation said teams were dispatched to tend to the situation.
The City of Mbombela has ordered residents living downstream of Senteeko Dam, situated between Kaapsehoop and Barberton, to evacuate immediately.
The municipality said the dam wall is approaching failure following days of relentless rainfall across the Mpumalanga province.
Mayor Sibongile Makushe-Mazibuko confirmed the severity of the situation, saying: “Senteeko dam wall is busy failing due to the rain.”
She warned that a collapse would send a devastating wall of water through multiple river systems.
“If the dam wall does fail, there will be a 1.82 million m³ rush of water into the Suidkaap,” Makushe-Mazibuko said.
Affected areas
Residents and businesses in the following areas are urged to move to higher ground immediately.
- Suidkaap from the top of the river down to Consort
- Those along or near the Kaap river from Consort to Kaapmuiden, and
- Areas around or near the Crocodile River
She said the situation was unpredictable.
“Please be on alert and don’t wait for the dam to break. If you are in the pathway, evacuate [immediately] and get to a safer place,” she said.

Assessment teams dispatched but unable to reach dam
The department of water and sanitation confirmed it had been notified about the private dam’s precarious condition and had mobilised response teams to assess the structure.
Speaking to The Citizen, the department said that the dam was “at risk of collapsing”, but it was not able to assist.
“Currently, teams from Inkomati-Usuthu catchment management area have been dispatched to the dam in question to assess the structure. However, they are currently unable to access or reach the area due to flooded roads,” it said.
The department indicated that more information would be forthcoming once conditions permit proper evaluation.
When asked about specific evacuation zones, the department directed inquiries to the municipality that issued the evacuation orders for areas along the affected rivers.
