There's no simple solution for Christchurch residents affected by floodwater every time it rains. 
Canterbury was battered with heavy rain on Saturday and early Sunday, causing surface flooding and road closures, driven by the remnants of ex-cyclone Dovi. 
The area of Avondale bore the brunt of the weather. 
Mayor Lianne Dalziel told John MacDonald these issues can't be fixed overnight. 
“There is going to be a lot more work done that is going to have to address these levels of exposure.”
