irrigation methods; surface and pressurised. The majority of irrigation
systems currently in operation in the province fall in to the pressurised category. Pressurised systems can be
further differentiated based on the method of operation and equipment used. A summary of the systems
encountered in the region is given below.

2.4 Irrigation to Land of Leachate
Situated north of the compost and vermiculture operations is a series of leachate ponds that collects
run-off from these activities. In addition to the collection of leachate and stormwater that falls in the
composting area, wash down water from the truck wash is also collected in this pond; which further
dilutes the compost leachate.
Figure 2 highlights the area in purple, where water from these ponds are irrigated to land. Typically

creation of stable interlocked layers of green waste ensures that it does not fall off, or get
blown off the cliffs and down onto the coastal marine area or into the sea.
From observations made during the inspection of the site no adverse environmental effects were found, or
were expected to have been occurring, as a result of the activity authorised by consent 7374-1.4.

* The productive class is defined by River Environment Classification (REC) types, with a combination of dry climate categories
and soft-sedimentary, volcanic acidic and volcanic basic geology. All sites that do not fall in these categories are in the default
class.
