Dam safety
All Sydney Catchment Authority (SCA) dams must meet the requirements of the NSW Dams Safety Committee under the Dams Safety Act 1978. The Dams Safety Commitee is the State's regulator for dam safety. It is responsible to develop and implement policies and procedures for effective dam safety management to protect life, property and the environment from dam failures.
The safe and responsible management of its 21 prescribed dams is also vital to ensure compliance with the SCA's Operating Licence.
The SCA does this through a structured program of surveillance and monitoring procedures that comply with the requirements of the NSW Dams Safety Committee, and national and international best practice.
In accordance with the Guidelines on Dam Safety Management, published by the Australian National Committee on Large Dams, the following surveillance is generally required:
- continuous surveillance including inspections, monitoring, surveys, chemical analysis of leakage water, and seismic monitoring
- periodical safety reviews typically including flood studies and risk assessment
- remedial action where appropriate
- safe operation and maintenance, including keeping up-to-date manuals and procedures
- emergency management, planning and implementation including conducting emergency drills
- ongoing personnel training.
