A photograph of a portaloo outside a residential property in Christchurch. After the 22 February 2011 earthquake, many houses had no running water and were forced to use chemical toilets or portaloos placed along the street. There is flooding and liquefaction on the street in the foreground. Liquefaction silt has been piled on the side of the road and a road cone placed in front.
