Steenbras Lower dam is one of a number of structures that form a crucial part of Cape Town’s water storage infrastructure. Originally constructed in 1921, Steenbras Lower dam was raised by 12.3m in 1927 and by a further 1.98m in 1954.
Dr Mothersille was invited by key representatives from the Cape Town Municipality to inspect the condition of the dam, with particular reference to the post-tensioned anchors installed to ensure structural stability. The contents of Dr Mothersille’s report will assist in developing a forward strategy for maintenance of the dam.
