6. HYDRAULIC BALANCE FOR EFFLUENT APPLIED
6.1. The Water Balance
To have an effective effluent irrigation system, it is essential that the correct amount of effluent is applied
at the right times to meet the crop requirements while ensuring increases in runoff and percolation are
minimised. A water balance should be constructed to determine the maximum volume of effluent that
could be sustainably used on average each year. The elements to be considered in a water balance are:
(a) precipitation
(b) effluent applied
(c) evapotranspiration
(d) percolation
(e) runoff
Significant amounts of percolation and runoff occur as a result of natural rainfall events. However, to
ensure a sustainable system, percolation and runoff should not increase significantly above rain fed
conditions thereby increasing the risk of pollution and changes in catchment hydrology.
The water balance is generally expressed as follows:
Equation: Water balance Precipitation + Effluent applied = Evapotranspiration + Percolation + Runoff
EPA Guidelines: Use of effluent by irrigation (October 2004)
6.2. Precipitation
The rainfall data over a historical period is used. This data can be obtained in monthly or daily format from
the Bureau of Meteorology.
6.3. Effluent Applied
The amount of effluent to be applied can be expressed as volume (ML). Seasonal variations in effluent
volume must be taken into account together with any impacts on effluent volume as a result of significant
rainfall events. Discounting for losses from spray irrigation can be used with caution when it is obvious that
some water will be lost for example during low humidity and high temperature. However, for the amount
that evaporates before reaching the ground, there will be a similar reduction in available evaporation.
Therefore any estimated allowance for spray losses must be accompanied by an estimated reduction in
evaporation and must be seasonally adjusted based on an analysis of local data.

6.4. Evapotranspiration
Is the sum of evaporation and plant transpiration from the Earth's land and ocean surface to the
atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil,
canopy interception, and waterbodies.
This will vary throughout the year depending on temperature, humidity, solar radiation, wind, crop type
and crop growth patterns. It can be estimated by multiplying daily or monthly evaporation values for a
district by the appropriate crop factor for the particular species of plant to be grown.
EPA Guidelines: Use of effluent by irrigation (October 2004)
6.5. Crop Factors
The crop factor takes into account plant productivity, and the meteorological factors. Crop factors are
sometimes expressed on different bases. Some are expressed as the ratio of crop evapotranspiration to pan
evaporation while others are expressed as the ratio of potential evapotranspiration to crop
evapotranspiration. The difference between pan evaporation and potential evapotranspiration is known as
the pan factor.
EPA Guidelines: Use of effluent by irrigation (October 2004)
6.6. Percolation
Percolation is the movement of water down through the soil profile and is a natural phenomenon after any
rainfall event that exceeds the soil moisture deficit. An irrigated site will have more percolation than a site
with rainfall only. Percolation is a process that prevents build-up of salt in the root zone. In humid coastal
and mountain areas percolation due to natural rainfall may be sufficient to prevent salt build up, but in dry
climates, a small fraction of irrigated effluent may be all that is required to leach salts out of the root zone.
The need for deliberate percolation of effluent will also depend on the salt tolerance of the plants and the
salt concentration in the irrigation effluent. Percolation must not simply be used as a means to dispose of
effluent to the environment as there is potential for other pollutants (e.g. nitrates) to be leached in
addition to salts. The rate of salt accumulation depends on a number of factors including the effluent
salinity, hydraulic loading, rainfall and resulting natural leaching. One simple method for determining the
fraction of irrigation water required to leach salts is to use the following equation:
Equation: EC (irrigation water) ÷ EC (50% yield reduction)
For example, if EC (irrigation water) is 0.75 dS/m (TDS = 450 mg/L) and EC (50% yield reduction) is 8.8 dS/m
(TDS = 5,280 mg/L), then the required fraction is 0.085.

IRRISEC1-12_EPA ANNUAL RETURN_LIC NO 3465_SEP2015 – SEP2016 21
If the annual effluent application is 800 mm, then the annual leaching requirement is 68 mm (0.085 x 800).
However, the most direct way to determine the need for deliberate leaching is to monitor salt levels in the
lower part of the plant root zone. If these start to increase to above acceptable levels then leaching is
required.
EPA Guidelines: Use of effluent by irrigation (October 2004)
6.7. Runoff
Irrigation tends to increase runoff due to the reduction in the amount of rain needed to saturate soil to a
point where runoff occurs. Therefore, runoff as a result of irrigation with effluent should be set to zero in a
water balance. This will provide a safety factor to ensure that runoff is not used as a means to dispose of
the effluent to the environment and ensure that runoff does not increase significantly above the natural
baseline. Runoff, however, will occur during protracted or heavy rain. Runoff from irrigation areas also
should be controlled and managed to limit soil loss and export of nutrients from the site.
EPA Guidelines: Use of effluent by irrigation (October 2004)
6.8. Total Water Balance for each sector based on 150ML / year total irrigation and proportional
application
6.8.1. Irrigation Sectors 1 – 9, 11, 12
The hydraulic loading of these sectors on an annual basis can be shown to balance relatively easily as
shown below in the respective tables.
6.8.2. Irrigation Sector 10, 11
The hydraulic loading of this sector on an annual basis is shown to be out of balance. Irrigation sector 10
had an additional summer crop sown during the months November to February. These additional sowings
were not accounted for in the Hydraulic Balance calculations as to avoid confusion for the purpose of this
report.
Although irrigation sector 11 had an undesirable water balance result in 2014, it was carefully managed
during the year and soil moisture was monitored on a day to day basis too ensure that the water and
nutrients in the effluent irrigation were being recycled and not simply running off the land. As a result this
sector has been brought back into balance during 2015.

7. SOIL CONDITIONS
Significant steps have been taken by the Management of Geelong Leather to create a sustainable working
effluent disposal model that we believe to be Industry leading and a model for others in the Industry to
follow. A model that deals with the waste products from the plant, yet continues the long term agricultural
productivity of the farm land associated with the leather plant.
Steps taken;
(a) A thorough review of the plant and farm practice, identifying the significant issues affecting the
long term soil health and therefore the viability of the practices currently in use.
(b) Scientifically calculated reduction of effluent application in line with the existing soil E.C and
Chloride levels, particularly on the oldest sectors. These targets are adjusted on an as needs basis
over time. A significant reduction on individual sectors has been implemented.
(c) The major capital investment in the purchase of the adjoining property. Effectively this will halve
the long term effluent load across all sectors due to the doubling of the arable area. Once the
irrigation capital projects are completed, the plants long term future is secure.
(d) A change in plant practice, removing much of the Chloride from the waste effluent, before
application.
(e) Extensive testing for Cadmium across all sectors showed that this was not a risk.
(f) A conscious farm Management plan, focusing on high nutrient removal production systems with
more Hay, and a continuation of summer crop/pasture have led to increased nutrient removal.
Reference to Table 3.2 shows that the soil Chloride levels continue to fall and now all Sectors fall within the
target range of less than 150 mg/kg of Chloride. What is the most pleasing with this data set is that our
deep soil Chloride level in the 30 – 60 cm tests have declined and with the only exception being Sector 4
which is stable and I would expect it to fall in line with all other sectors.
Clearly the implementation of the recommendations made previously and plant operational changes are
working.
Good Applied science is to test, make changes and re-test and this is showing excellent and pleasing long
term decline in the Chloride soil load.
All other agriculturally significant elements and measures, pH, Phosphorous, Nitrogen and Sulphur remain
within long term sustainable limits.
The Physical structure of the soil is excellent and significantly better than on many of the district properties.
I hypothesize that the soil Biota, amoeba, fungi, nematode’s and earth worms feed on the effluent products
and have had a beneficial soil structure impact.

The soils across all sectors continue to show good porosity and water infiltration rates remain high.
Crop production remains very high by district averages with significant biomass production, greater than 8
tonne of dry matter production anticipated in the 2016 year.
C. Levitzke, Agronomist, Rodwells Culcairn
8. VEGETATION CONDITION
In this year, 2015/2016, crop establishment has been good for both crop types grown Oats and Wheat. The
soils ability to handle an exceptionally wet winter is significantly better than those properties adjoining
which reflects good control traffic practices put in place by the farm manager and also the soils inherent
porosity.
We anticipate the wheat should yield 4 – 4.5 tonne / hectare and that dry matter Oaten hay yields will be
greater than 8 tonne of dry matter / hectare and possibly higher depending on continued soft finish to the
growing season.
There have been no significant crop issues reported this year. It has however been an exceptionally wet
winter with 570mm of growing season rainfall recorded leading to some areas of the farm being submersed
in water.
C. Levitzke, Agronomist, Rodwells Culcairn
9. ASSESSMENT OF PERFORMANCE OF THE CROPPING SCHEME
9.1. Irrigation Sectors 1 - 12
The cropping program has continued annually on these sectors with excellent crop results. There are no
crop growth impediments observed in the irrigation sectors by the agronomist, nor any issues reported by
the shared farmer. In fact the moderate nitrogen and phosphorous environment leads to very good crops
being produced, generally above district averages.
Proof of this has been shown by the continued high production levels produced on the farm with little or no
ill crop effects.

10. IDENTIFIED SUSTAINABILITY INDICATORS
10.1. Irrigation Management
Reduced effluent application across all Sectors to target 1.0 ML/Ha and further reduction to 0.7 of a ML/ha
on sector 4 have achieved exactly what was anticipated with Chloride levels falling within the target
guidelines of 150 mg/kg of Chloride. This is a very satisfying outcome.
An annual review of the performance of the irrigation management system by Chris Levitzke, Rodwells
Culcairn, from data collected on operation and environmental performance will assist Geelong Leather with
identifying areas of potential risk and improvements to the system ensuring the effluent is being managed
in a responsible, sustainable fashion for the long term.
The Additional Farm Purchased in this year as previously stated will double the amount of arable land
available to Geelong leather to apply effluent to.
This property has already had 1.0 t/ha of Lime applied and 1.0 t/ha of Gypsum applied. It has had very long
history of poor farming practice, one way disc workings resulting poor soil structure, low porosity and
significant hard pans. This property will respond very well to another tonne of gypsum being applied and
good control traffic farming practice. There is no soil type difference between the two properties and
envisage that the new property will be equally productive in time.
10.2. Crop Selection
The choice of the crop to be grown by Geelong Leather in an effluent irrigation sectors involved considering
the following factors:
(a) Characteristics of the soil type, topography, climate
(b) The effort needed to manage the irrigation area
(c) Level of management of irrigation application
(d) Cultivation, planting, and harvesting operations
(e) marketing of agricultural products
(f) weed control
(g) Possible need for tolerance to high nutrient levels or salinity
(h) Ability to accumulate nutrients – if nutrient loads are high then crops capable of using these
nutrients are preferred
(i) Water requirements – crops with higher water use may not necessarily be the best because water
is often in short supply compared with the amount of nutrients to be used for irrigation producing
Lucerne or Sorghum
(j) Financial considerations – capital costs, operating costs.

With the above in mind Geelong Leather has found that cropping programs using a combination of the
following have best performed year after year; Wheat, Barley, Sorghum, Oats and Canola. This selection has
ensured Geelong Leather is able to maximise the removal of nutrients through harvesting and minimise the
accumulation of nutrients in the soils to achieve a sustainable site nutrient balance.
11. IMPACTS (NON-COMPLIANCES)1
11.1. Irrigation Sectors 2, 4, 6
Chloride levels are now at sustainable long term levels and the current effluent application rates can be
maintained until the new irrigation works are completed on the new block at which time we could halve
our application rates again.
11.2. Irrigation Sectors 1 - 12
Undesirable chloride levels were being discharged in final effluent from November 2014 until May 2015.
The chrome supernatant, generated from the highly efficient chromium removal process, is the main
contributor to the undesirable chloride levels. However since the end of May 2015 the chrome supernatant
has been diverted to one of the onsite 40ML evaporation ponds, reducing the chloride levels below
700ppm and final effluent discharged by 25%.

12. RECOMMENDATIONS FOR FUTURE ACTIONS2
12.1. Irrigation Sectors 2, 4, 6
Chloride Reduction – maintain current effluent application rate of 1ML/Ha to 0.7ML/Ha for this season with
planned reduction or full rotation onto the new block.
12.2. Irrigation Sectors 1 - 12
Geelong Leather will continue to transfer the chrome supernatant to the one onsite 40ML evaporation dam
to aid in removing as much chloride from the effluent discharge as possible, hence reducing the load on the
land. The second 40ML dam will only be considered if the current dam does not achieve desired
evaporation rates.
Hay making will be increased on the farm as a general practice. It removes the maximum nutrient load per
hectare. Further Straw removal following harvest of coarse grains such as wheat and barley also removes a
further, admittedly small proportion of nutrients.
12.3. Procurement of Additional land
The purchase of the adjoining farm in July 2016 will also, over time, once the infrastructure is completed
(June 2017), allow the irrigation effluent to be effectively halved in application rate. That plus the reduced
effluent concentration will in effect make the plant at current production levels future proof in its effluent
management.
2 So as to achieve a sustainable effluent management system.
