during the year (four relating to high
rainfall, and one relating to a potable water leak). All of these incidents were deemed compliant with
consent conditions upon further investigation. There were also 19 wastewater incidents that occurred
throughout the wider wastewater network; 12 of which were related to high rainfall that occurred in
November and December in 2020. One incident occurred when a contractor left a pipe plug in the sewer
following maintenance, which resulted in an overflow
confines of Port Taranaki.
The Taranaki region has a temperate climate with
generally abundant rainfall. The incised nature of
ring plain streams means that flooding is not a
major problem. However, occasional intense rainfall
events can lead to rapid rises in river levels and
flooding in hill country valleys and elsewhere.

Rainfall: The report covers average rainfall by season, and trends in rainfall within each
season. It also presents information on trends in intense rainfall episodes. The report goes on
to note that climate change modelling suggest there will be an overall pattern of increasing
rainfall in winter and spring down western New Zealand and across the south of the South
Island, with drier conditions to the
the 2018-2019 monitoring year, with most
commencing irrigation in November or December and concluding for most in March. Rainfall recorded at
the Council’s monitoring locations over the summer irrigation period ranged between 58% and 111% of
historical mean values. A particularly dry October, along with warm coastal winds, caused soils to dry out
faster than normal which resulted in high irrigation water demand. Total usage during the 2018-2019
irrigation season, with a total water use across
