Christchurch's quake-damaged water and waste systems are coping well despite freezing conditions and peak flows due to thawing snow.

Christchurch City Council water and waste manager Mark Christison told Radio New Zealand that there had been concerns about the impact the freeze and thaw would have on the pipes that had been damaged on and since the February 2011 quake. 

Christison says the thaw was causing twice the volume of water to flow through the storm water network, but the treatment plant in Bromley was holding up.

The normal flow through the plant is two-and-a-half cubic metres per second. On Thursday, it peaked at five cubic metres per second.

Christison said most of the water pipes and sewers were below freezing level, but the council was keeping a close eye on them.
