general, there are two types of irrigation methods: surface and pressurised. The majority of irrigation
systems currently in operation in the region fall into 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.

The camp was quiet at the time of inspection with only one caravan on site. There were no odours or visual
issues near the WWTP or trenches. The sea was rough (BF3) with strong onshore winds. The WWTP
appeared to be operating in compliance with its consent conditions at the time of inspection.

The monitoring inspection was completed late this month due to heavy rain prior which may have masked
any effects from the WWTP. The camp was reasonably busy at the

An inspection was undertaken to assess compliance with resource consent conditions. It was raining at the
time of the inspection. Four samples were obtained; one downstream (clear), one upstream (clear), one from
the storm water discharge pipe (turbid) and one form the head waters adjacent to the storm water
discharge pipe, at this location there was a visible sheen. The

away from the front crank bearing, damaging the engine.
When using contractors or hiring equipment, make sure that the equipment used has been
cleaned before use on your farm. This is so diseases are not transferred within the effluent
from one property to another.
There are two types of contracting operations - pump spreaders and vehicle spreaders
(honey wagons). It is the

stream was turbid and brown in colour. The piggery wastewater flow rate from the final pond was
estimated to be at 14 L/s.
The wastewater discharge from the final pond had no visual downstream environmental impact on the
Waiongana Stream at the time of the survey. The consent holder continued to discharge for a
abstraction permit (groundwater)
Section 14 of the RMA stipulates that no person may take, use, dam or divert any water, unless the activity is
expressly allowed for by a resource consent or a rule in a regional plan, or it falls within some particular
categories set out in Section 14.
