During the year under review some unacceptable material was dumped at the Pātea Beach green waste
discharge site, but it was removed promptly by STDC. There was no leachate observed discharging from the
sand dune area or the stockpiled green waste during the period under review, or in previous years. These
factors, combined with the sandy substrate and low rainfall at the beach should be restricting the
production of leachate from the green waste. It
cyanobacteria were higher than in the previous
three seasons, and similar to the preceding two seasons, probably a reflection of the relative amounts of
rainfall causing freshes that scour streambeds of periphyton.

Timely reporting of the results of bacteriological water quality and cyanobacteria numbers/cover was
undertaken by use of the Taranaki Regional Council website (www.trc.govt.nz) and LAWA website

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.

2019-2020 monitoring year, with most
commencing irrigation in late October and concluding in March. Rainfall recorded at the Council’s
monitoring locations over the summer irrigation period ranged between 85% and 114% of historical mean
values. Total usage during the 2019-2020 irrigation season, across all exercised irrigation consents was 8,835
ML. This was more than that used during the preceding 2018-2019 monitoring year, when 56 irrigation
consents were exercised, and a total usage of 6,906 ML. …
