three day period
following significant river/stream fresh conditions. [NB: regional differences in
rainfall patterns have caused difficulties at various sites in the past as localised
rainfall may impact on bacteriological quality on isolated occasions]. Where
necessary, a 2 metre sampling pole was used for bacteriological sample collection
immediately beneath the water surface and at a minimum of calf depth at the sites.
Thirteen samples were collected from all but one site (12 samples)
increasingly popular as storage system, which is easy to install, reduces odour and no
rainfall into the tank means you can considerably reduce the amount of storage needed, an option to consider
in high rain fall areas.
Typically, farm dairy effluent is directed to a sand trap then tank with pump system, effluent is then applied
directly to land or to the bladder.
The Bladder will have a return valve, effluent is gravity feed from the bladder back to the tank, were it is then
applied to land

survey period. It has been noted, during past survey periods, that the three-day post
rainfall sampling protocols followed by the SEM programme for the other (ringplain)
catchment sites are not necessarily appropriate for baseline assessments of
bacteriological water quality at this site near the mouth of this predominantly eastern

Kayaking and rafting
The Waiwhakaiho River is one of the five main whitewater kayaking rivers in Taranaki, along
with the Stony, Mangorei and Manganui Rivers and Kiri Stream. The Waiwhakaiho is navigable
from the National Park to the sea, and flow recommendations are for after rainfall at 20m3/s,
although it is possible to ‘scrape by with less’.
There is no advertised commercial rafting on the Waiwhakaiho River, but it is offered by
TOPEC as one of their adventure
