The Serpentine Pipehead Dam was constructed to use the Serpentine River, in Western Australia, to convey water from Serpentine Dam to the interconnection with the metropolitan trunk main network. The dam is also used to store water from the Dandalup scheme whereby water can be pumped or gravity transferred back into the Serpentine Pipehead Dam.
A dam was constructed in Western Australia along the Serpentine River, with the purpose of redirecting water from the nearby Serpentine Dam to merge with the metropolitan trunk main network. Additionally, this dam serves as a storage facility for water from the Dandalup scheme, enabling the use of gravity or mechanical pumping to return water to the dam.
