Peter A. Ballantine
In view of the need for a safety upgrade for the Quipolly Dam and the plans of Liverpool Plains Shire Council for future growth in water supply, the Council took the opportunity to increase the storage capacity of the dam by raising the full supply level by 2.0 m. In 2009, the Council appointed GHD to design the upgrade in accordance with the ALARP principle.
The design of the dam included an innovative vertical crest wall, embedded into the embankment, a concrete-lined auxiliary spillway placed over the embankment adjacent to the existing spillway and the installation of Hydroplus Fusegates in the existing spillway channel.
This paper describes the design of the upgrade works.
