Black Creek Diversion Channel
It was therefore necessary to increase the space available for ash storage by reducing the required stormwater storage volume in the ash dam through the effective reduction in the size of the ash dam catchment. The Black Creek Diversion Channel is designed to carry storm water from the Black Creek catchment around the ash dam into Meandu Creek.
The Diversion Channel is 3.2km in length, and typically 30m wide at natural surface level.
York Civil was awarded the contract for the diversion around the ash dam, which comprised 570,000m³ earthworks, one road bridge, one pipe services bridge and 4.7km of new and re-worked unsealed roads.
