Reforming Leak Detection and Repair of Christchurch's Earthquake Damaged Water Supply Network
Annual Conference
❄
Following emergency repairs as a result of the February 2011 earthquake, the Christchurch water supply network was left in a fragile condition. Leakage levels were 2 times greater than prior to the earthquakes and the overall resilience of the network was not well understood.
This paper outlines how the Stronger Christchurch Infrastructure Rebuild Team (SCIRT) went about reducing leakage from the potable water supply network to pre-earthquake level and reforming how the water supply network is viewed, worked on and managed. The question authorities in New Zealand’s other urban centres may be asking is: how unique were the circumstances described to Christchurch & what of this applies to us?
