Extent of storm water system damage
Fortunately, the earthquakes left the stormwater system largely in a functional state. There was still some damage, but the system is catching most storm water and most breaks have been temporarily repaired.
About one fifth of the storm water system has been properly assessed for damage, however we can tell that the system is performing acceptably with only moderate impact from the damaged parts. Most of the assessing equipment like CCTV cameras are busy surveying the more seriously damaged wastewater systems.
