rainfall events, or if animals have direct access to waterways. Human faecal
contamination of waterways can occur via poorly treated sewage or septic tank systems, or during heavy rain
when sewerage systems cannot cope and they overflow into stormwater systems. Because of these
heightened health risks from runoff and stormwater, people are often advised to avoid swimming for 48 hours
after prolonged or heavy rain.
There are two distinct components to assessing the suitability of a site for

3.3 Stability
The Kaitake Range is stable but in recent times landsliding has occurred on steeper
southern slopes during high intensity rain storms resulting in downstream channel
damage.
The Pouakai Range is also displaying evidence of more recently increased
landsliding and some channel deterioration in the north-eastern area in the upper
Oakura River catchment. The majority of the range is stable.

green waste being discharged onto the dunes. The discharge site is approximately 120
metres long and 25 metres wide, and is shown in Figure 2.
Patea Beach is an elevated site which for most of the time is dry. Rain that does fall on
the site drains away at a very rapid rate. The site does not suffer from flooding from
rain or tidal action, due to its elevation. Monitoring over the past four

unsuitable for disposal which may be present in the land parcel.
• A maximum daily flow to the field of 5,000m3 to allow some contingency above
the average flow. This equates to 78th percentile flow.
• Disposal only when the day’s rainfall is <10mm.
• When rain prohibits land disposal, all effluent is discharged to the river.
• Storage not allowed for.
The above assumptions would require a disposal field of 165ha including buffer zone.
Using the inflow and rain data, river
prevent leachate from entering surface waterbodies, groundwater or stockwater.
Site silage stacks so that overland flow of water from heavy rain cannot enter the stack.
Site feed areas away from waterways.
Distribute feed so as to minimise soil damage (from farm equipment and animals) and potential surface run-off to waterways, i.e. avoid Critical Source Areas.
Deer: Make sure silage is made at the optimum moisture content to reduce possible leaching, recommended at 30% dry matter or more.
