Figure 6.1: Central Highlands Water location and boundaries Asbestos Cement Pipe Maintenance at Central Highlands Previous approach Prior to its current approach to pipe removal, Central Highlands Water was replacing asbestos cement pipes using the bursting’ technique and leaving fragments in the ground. However, in 2015, the ‘pipe Victorian Government clarified that asbestos fragments left in the ground after pipe bursting classified as asbestos waste and as a result these required removal and disposal. Based on this clarification, Central Highlands Water transitioned to its current asbestos removal methods. Current approaches Central Highlands Water currently has two approaches for removing asbestos pipes. Both methods follow the and remove’ strategy, but the specific approach depends on the nature of the pipe. ‘excavate If an AC pipe cracks, Central Highlands Water assumes that the removal process will involve friable asbestos. In response, a Class A licenced contractor is engaged to remove the pipe. If the AC pipe is not cracked, the asbestos is bonded (or non-friable) and can be managed internally by the appropriately trained and licenced Central Highlands Water staff. Further details on these two approaches are provided below. Approach One A non-cracked AC pipe – Appropriately trained Central Highlands Water staff undertake the removal of a non-cracked AC pipe. Training covers the hazards associated with asbestos in accordance with the Regulations, and for a staff member to conduct the removal, training must have occurred within the past two years. Mandatory requirements for the removal of non-cracked AC pipe includes: Completion of a job safety and environment analysis (JSEA), includes an outline of the necessary Personal Protective Equipment (PPE); Handling, transport and disposal carried out in accordance with EP regulations; Notifying adjoining commercial businesses (including schools, retail etc) immediately it is determined necessary to cut and or remove AC pipe; If cutting is required, Central Highlands Water will remove an entire section of pipe (6 metres), rather than limiting the removal to the damaged area; Completion of an Asbestos Removal Control Plan. The procedure for removing non-cracked AC pipe at Central Highlands Water is outlined overleaf, followed by a real-life example of this removal process.
