An articulated water truck was travelling to a rig site carrying 22,000L of treated water. Whilst rounding a bend in a 40km/h in-field dirt road, the truck rolled over onto its side. 11,000L of treated water was released from the top fill hatch. 200L of diesel was spilled from the truck’s fuel tank breather. The driver was unable to escape the cabin until assisted by another driver who arrived three minutes after the incident. The driver was transported to hospital, treated for a broken collarbone and was off work for six weeks.
