Water New Zealand say messages about preventing sewage blockages not getting through to Kiwis.
People using their sinks and toilets as "waste disposal units" have been responsible for many of the sewage overflows during the dry weather this summer.
So says Water New Zealand, which has just published its latest performance comparison report, the 2017/18 National Performance Review (NPR), which looks at the state of our drinking, storm and wastewater assets.
The majority of the overflows have been caused by blocked pipes, an all too common outcome of people treating their toilets and sinks as waste disposal units, the review says.
The NPR found that since 2015-16 the number of sewage overflows occurring during dry weather blockages has increased five-fold.
