Mardi Dam works

Essential upgrade works, including the construction of a new intake tower, two pump stations and new pipelines are currently being undertaken at Mardi Dam. These upgrades are vital for the long term secure operation of Mardi Dam and the Central Coast water supply system.

Due to the construction of the new intake tower, the water levels in Mardi Dam are being lowered to a safe level for construction.

The work has been timed to coincide with the natural drop in Mardi Dam over the summer months (due to seasonally low streamflows). Levels will return to normal once the work is complete.
