Note: Council expectation is that all consents issued will require an exclusive discharge to land and
full storage. Dual discharges may be allowed, if the dairy farm is in a high rainfall area and provision
of adequate storage is impractical. The discharge of treated farm dairy effluent to surface water may
be authorised as a contingency, when land

catchment. It runs from south-east to north-west. Almost the entire valley formed by the Stream is owned
by the Company, and consists of steep eroded hillsides, multiple side gullies, and small river flats distributed
along its length. The area receives more rainfall than the northern Taranaki coastline to the south-west. Soils
are generally poor and highly erodible. Patches of bush and planted trees cover most of the hillsides, with

how dry or wet a summer is. River flow measurements can
help us ensure water use is managed in a way that protects
freshwater ecosystem health. Find more information on
