improvements. Rainfall in Taranaki does expedite run-off of E. coli and other contaminants
into waterways however, an assessment of earlier ‘dry-weather’ swim spot monitoring data
found that 11 out of 16 sites were still failing the minimum standard, indicating direct
contamination of waterways is a significant issue.

Committee of the intention to accelerate the removal of treated farm
dairy effluent discharges from waterways, in most cases. On the upper ring plain
land discharge may not be possible at all times and some discharge of highly
treated waste water may be required. A study on the options for dairy shed and
waste treatment systems in this high rainfall area is being investigated. The
requirement to discharge to land, in most cases, addresses cultural and water
quality concerns.

during the 2021-2022 monitoring year, with south Taranaki
commencing irrigation in November and the rest of the region beginning in January. Irrigation concluded
late April through to early May across the region. Rainfall recorded at the Council’s monitoring locations
over the summer irrigation period ranged between 82% and 203% of historical mean values. Even though
rainfall volumes were higher than previous years, the irrigation season was longer with total irrigation water
usage of 6,960 ML
