Authorities are advising people to stay away from the Benoni dam that caved in this week.
BENONI - The work of fixing the partially collapsed Benoni Lake wall continues.
Ekurhuleni officials say they're now employing a new water draining method which they say is efficient and not too taxing financially.

The process of repairing the partially caved-in wall is no easy feat, and it's also a costly operation.
Ekurhuleni COO, Joe Mojapelo explained, "each of these pumps pushes about 10 litres of water per minute.
"They were struggling and as a result, we deployed the big machine which is called the hydron, which pushes about 26 thousand litres per minute."
"They are operating at huge amounts of money, we're burning about R100,000 worth of diesel every day."
Ekurhuleni mayor Mzwandile Masina says this simply has to be done, whatever the cost.
Fixing the partially collapsed dam wall will take about four months to complete.
But authorities say the roads around the dam will be opened as soon as they check the integrity of this structure.
