Wastewater system damage

Printer-friendly version

The earthquakes have caused several different kinds of damage to our wastewater system:

Treatment plant damage
The earthquakes badly damaged the Christchurch Wastewater Treatment Plant and its oxidation ponds, although it continued to operate at a reduced capacity. Clarifiers were also badly damaged. As a temporary measure, for a short period, the effluent that was pumped into the ocean was not treated to the usual safe level.
Cracks
The earthquakes cracked pipe walls, allowing all kinds of other liquids and obstructions into the pipes. The liquids include groundwater and liquefaction silt. These are a problem mainly because they reduce the carrying capacity of wastewater systems.
Collapses
Some wastewater pipe sections completely collapsed, particularly older earthenware pipes. Wastewater pipes suffered more collapse than fresh water pipes because they had a higher proportion of old materials. Many wastewater pipes had to be diverted before repairs could commence.
Joint breakage
Where some pipes have been joined together, the shaking has separated the two parts again, so the pipe is essentially broken.
Pump station damage
Sewer pump stations and their pressure mainssuffered varying damage. We need to completely replace some of them. For a brief time, effluent was pumped into urban waterways because the sewer pump station network was so damaged.
Loss of gradient
Pipes generally run water in a downward gradient to take advantage of gravity. Liquefaction pushed some pipes up, which reduced the gradient over a widespread area.
