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

2.3.2.3 Method of irrigation
The effluent from the piggery is pumped to storage pond prior to land application. The Company
communicated that three different delivery systems were used during the 2020-2021 monitoring year:
1. ‘Weta’ travelling rain gun, this was utilised to apply effluent at depths of
rain throughout the catchment. At the time of
sampling the stream was in fresh (recession) and running at a moderately high flow rate at 7.3 m3/s. 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
before being pumped to a nearby reservoir. The water supply is reticulated to approximately 2,300 separate
customers.
Filter backwash is discharged via a large pond. The outlet from the pond is an inverted pipe located at the
opposite end of the pond from the inlet. The discharge from the pond emerges from the pipe to fall over a
small waterfall. At the base of the waterfall the discharged water runs down a natural cobbled channel
beneath native riparian vegetation for approximately 10m

The site was busy with normal operations. Traffic was particularly busy within the scrap area and some swarf
was observed tracking to the drains. All drain screens were in place and appear to be regularly maintained
to prevent blocking. All hazardous chemicals were appropriately contained. Rainwater within bunding was at
a low level. Spill kits were in place throughout the site and
