The Department of Water and Sanitation (DWS) is investigating the integrity of the privately owned Tiryvillle Dam near Kariega in the Eastern Cape.
This follows reports of the dam being at risk of failure due to the recent flash floods.
A spokesperson for DWS Wisane Mavasa says a team of engineers has been dispatched to assess the condition of the dam and is in continuous engagement with the Nelson Mandela Bay Municipality.
She says it has been established that the dam is a concrete structure which ideally should be able to cope with water flowing over the dam wall.
However, due to a lack of historical information on the condition of the dam, it is prudent to treat the dam as a possible high risk and to take measures to safeguard the lives of the communities living downstream of the dam.
On Monday approximately 200 families living at Lapland informal settlement and surrounds were evacuated.
Mavasa says details of the owner of the farm dam are not known as the dam is not registered as a dam with safety risk with the DWS safety office.
She says they will advise the Metro on any measures to be taken.
