While the off-road dump trucks were delivering water to the fire, a pumping system for conveying larger volumes of water approximately 2000 metres from the onsite dredge pond was erected. The system involved pumping water from the dredge pond into leachate collection ditches. The flooded ditches were used to convey the water to the vicinity of the fire. A 500 m long pipeline was established to convey the water into a large spray irrigation cannon. The spray irrigation cannon was capable of delivering approximately 14,000 litres of water per hour and operated continuously for a week commencing on October 20th. To prevent air from entering the demolition layer, a cap of silty-clay from the dredge pond was installed along the 700 metre long bank of the demolition area. (see Photo 3).
