The flash floods caused some cars to be submerged in water at Johor Jaya.
JOHOR BARU: The Johor Baru City Council (MBJB) plans to carry out maintenance work in more than 100 retention ponds under its care, to help mitigate flash floods during downpours.
MBJB engineering department director Sulaiman Mohamad Taib said the ponds were usually covered with silt, rubbish and sand, which hampered their effectiveness during heavy rain.
