Sungai Bera Holding Basin

​

​

    • The SBHB covered 6 hectares and was used to “store” OBMs, cuttings, tank bottom sludges – within three unlined basins.
    • Estimated to be some 100,000 m3 of oily sludge within basins.
    • Plus 50,000 m3 of contaminated soil (underlying & surrounding the basins).
    • The major treatment systems were mobilised from Australia – so technology can be imported.
