Taswater Dam Safety Review

In 2016, AK Consultants were engaged to register a number of existing unregistered TasWater owned dams and lagoons as required under the Water Management Act, 1999.

The completion and compilation of all required documentation for registering existing dams included desktop and field assessment to complete key dam details such as catchment and spillway capacity calculations, a Dam Safety Compliance Check, and assessment of the Consequence Category in accordance with ANCOLD Guidelines 2012. This included;

– Initial Level Assessment Flood inundation mapping

– Estimated dam break peak flow and failure time

– Dam Failure Impact – Initial Assessment

– Estimation of Population at Risk (PAR).
