2001 – The Use of Portfolio Risk Assessment in the Development of a Dam Safety Program for Council-Owned Dams in NSW

PJ. Cummins, P.B. Darling, P. Heinrichs, J.Sukkar

The Department of Land and Water Conservation, Town Water Treatment and Recycling Branch, had identified a number of local government council-owned dams throughout NSW with deficiencies. SMEC was engaged to undertake a portfolio risk assessment to assist in the development of an appropriate program of remedial works.

The portfolio risk assessment methodology relies on the development of consistent assessments of failure probability, consequence level and cost estimate for mitigation measures. This tool enables a large amount of data on a portfolio of dams to be drawn together so as to provide decision makers with a coherent and robust basis for the development of a program of remedial works.
