A long-awaited report into the performance of local infrastructure during last June's flooding is finally about to be made public.

The Dunedin City Council initiated the report, which has reportedly been peer-reviewed.

Staff decided to investigate the performance of mud tanks in coping with record rainfall, following complaints by the public.

It's been suggested the council didn't maintain infrastructure to adequate standards, contributing to the devastation caused.

Some business and home owners are still dealing with flood damage, almost a year on.

The report's due to be considered in the council's next infrastructure services committee meeting on the 26th of April.
