To ensure the continued safe operation of dams, water corporations regularly review each dam against current design and construction practice, and upgrade the dams as necessary.

In addition to reviewing the dams, water corporations undertake regular dam safety monitoring and surveillance and routine maintenance activities. Monitoring and surveillance programs help to identify any serious problems in time to take remedial action and prevent dam failure.

Water corporations have invested around $200 million in capital works to improve the safety of their dams over the last 12 years. Further safety works are programmed on a continuous and progressive basis over the coming years.

The following information provides details about dams owned or operated by water corporations and past and future dam safety upgrade works.
