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.

also undertaken by the Council, from a stormwater drain located directly above the
weir on the Waingongoro River, to ensure any stormwater discharged meets consent requirements.
Sampling was not undertaken during or immediately following any heavy rainfall periods when stormwater
runoff would be at its highest.
The results of surface water sampling undertaken by the Council are included in Table 4 and Table 5 and are
presented against results undertaken during the previous reporting period
Hydrocarbon sheens were not observed within the skimmer pits or in puddles on any of the sites. The
skimmer pits were all in good order with goose neck pipes functioning as required. The turbidity of the pits
varied from clear to slightly turbid (following heavy rainfall the two days before). The majority of the
discharges were onto land before flowing to surface water. Some pits were unlined and empty. No effects
were noted in the surrounding vegetation (such as burnt patches or dead grass) or within
in discrete areas, such as near river mouths
and in close proximity to wastewater discharges. At river mouths, water quality can be
reduced as a result of contaminants from land use and development (e.g. farming,
earthworks, urban centres, industrial sites) entering waterways, particularly during or
following heavy rainfall events. Accidental discharges of largely untreated wastewater can
have temporary adverse effects on coastal water quality. Wastewater discharges from
