Temporary waste tanks are being trialled in Christchurch where households still do not have sewerage following the earthquake.
A number of people in Avonside, Dallington and Bexley are having to rely on port-a-loos or are sharing with their neighbours.
Christchurch City Council waste water manager Mark Christison says temporary tanks will be installed at properties that need them and will be pumped out daily by tankers.
Mr Christison says this will allow people to use their own facilities and give them some privacy again, until repairs to the sewerage system are made.
Up to 100 kilometres of waste water pipes need to be replaced, of the approximately 1800 kilometres of pipes in the city, he says.
