Summary:

The rehabilitation area consisted of approximately 100 ha with a significant fall of approximately 100 m (average ˜10% slope) from the top of the catchment to the discharge point. During bulk earthworks, final profiling and the early stages of revegetation a number of erosion and sediment controls were implemented with a sediment basin required prior to the discharge point to capture sediment mobilised from the rehabilitation area and prevent non­compliant discharges. Using a traditional approach to sediment basin sizing, a basin volume of approximately 80 ML would have been required, which due to its size, would need to be a permanent feature of the final landform.

A HES basin was considered as an alternative to a traditional sediment settling basin and modelling found that it offered a much smaller volumetric requirement, with an improved proportion of stormwater treated and allowed a flow­through approach rather than batch capture and treatment of stormwater.
