Groasis Technology is compared to drip irrigation over a 50-year project for a 500-hectare tree plantation. Key financial indicators show that using Groasis Waterboxes results in a higher net present value (NPV) of €26.62 million compared to €21.15 million for drip irrigation, and a slightly higher internal rate of return (IRR) of 22.1% versus 23.4% for drip irrigation. Waterboxx also has a longer payback period of 7 years compared to 5 years for drip irrigation. The document provides assumptions and calculations for costs and revenues for both systems over the 50-year period.

2. Remarks
Groasis Technology in comparison with drip irrigation
The project duration is 50 years as treeprojects (vines, olives,avocados, dates, etc.) always are longterm projects
All costs independent from use of Groasis waterboxx or drip irrigation that are equal have not been accounted in this document, so
this document does not show all costs of tree plantations
As an example: the cost for a warehouse is not calculated, as for both systems one needs a warehouse
This means that this document cannot be used as a template for tree planting calculations. It focuses only on the financial
differences caused by the use of the Groasis Technology compared to drip irrigation
Note: if column C in tab 'assumptions' states 1/0, complete calculation tab lines as following: Yes = 1, No = 0

Key charts
Net present value (NPV) is the total present value of a time series of cash flows; it measures the excess or shortfall of cash flows, in present value
terms, once financing charges are met. NPV is an indicator of how much value an investment or project adds for the investor; it is an indicator of
the value or magnitude of an investment.
The internal rate of return (IRR) is a rate of return used to measure and compare the profitability of investments. The internal rate of return on an
investment is the annualized effective compounded return rate that can be earned on the invested capital; it is the interest rate at which the costs
of the investment lead to the benefits of the investment. This means that all gains from the investment are inherent to the time value of money
and that the investment has a zero net present value at this interest rate. IRR is an indicator of the efficiency, quality, or yield of an investment.
Capital employed represents the capital investment necessary for the project.
Payback period refers to the period of time required for the return on an investment to "repay" the sum of the original investment (capital
employed).

12. Risk analysis
Groasis Technology Drip irrigation
if growing on rocks lower investment in soil higher investment in soil
if growing on rocks lower interest costs on capital investment in soil higher capital costs
No inflation of costs risk inflation of costs risk
no risk of higher costs for energy risk of higher energy cost
no risk of lack of availability of ground water risk of lack of groundwater
no risk caused by political decisions risk of political decisions
no risk on ban on use of groundwater risk on ban on use of groundwater if cities have lack of water during periods of drought
no risk on brackish water problems heavy use of drip irrigation may lead to brackish groundwater, already many areas world wide have been left for this reason
no risk on losing crop if use of groundwater is banned
risk of losing crop if irrigation is banned, this might happen with a severe drought when cities get priority. This might happen in the coming 100
years as a cause of climate change
no risk of rising prices of irrigation water
water price per liter will rise considerably, when price rises from 0,001 euro to 0,01 euro per liter (cost comparison cel J15) the cost of water rises to
625,000 euro (cost comparison cel G9). Drip irrigation production will then give a loss
No risk on soil salination
if irrigation water contains minerals and/or salt, over time the soil will be polluted and also too salted to produce and turn into unusable eternally.
This is undoubtedly the case with water from natural sources with high mineral levels, from cleaned sewage water sources of produced from
seawater through the reversed osmosis technology. Several formerly fertile zones in California have now been abandoned for this reason. Many
cities in the Middle East start to replace the soil where trees are dying as raising the water gift doesn't help anymore. The certain capital loss
caused by this reason is unimaginable high and cannot be solved others than by higher water gifts until the conductivity of the soil is higher than
that of the roots. Once this level has been reached the plants will die because of draught even if the roots are surrounded by water.See photo.

13. Other capacities
Groasis Technology Drip irrigation
growing on rocks possible growing on rocks not possible
sustainable - only in the first year water is used between 20 to 100 liters depending from the growing
place
not sustainable - plants are eternally irrigated with scarce goundwater or expensive filtered water through reversed osmosis. Trees in
cities in Middle East receive daily 60 to 100 liters per day. This is average 2,920,000 liters in 100 years. Vines receive between 800 to
1,400 liters per year per plant. This is average 110,000 liters per plant in 100 years. As soon as water is priced, this way of producing is
outdated.
less fungicide use = less risk for personel high fungicide use = higher risk for personel
higher product quality level lower product quality level
higher sales price for the product because of better internal and external quality lower sales price
eco label possible eco label not possible
less complicated management complicated management
less crop means less wear of machinery/ less use of energy/ less packing material/ lower
transportcosts/ etc. / these differences in lower costs are not taken into account in this template
double crop means double wear of machinery/ double use of energy in warehouses/ double packing material/ double transportcosts/
etc. / these differences in higher costs are not taken into account in this template
less crop means necessity of smaller buildings and smaller refrigidator / these differences in costs
are not taken into account double crop means necessity of bigger buildings and bigger refrigidator / these differences in costs are not taken into account
applying waterboxx can be done with low educated people and as the work itself is light, with
possibly with females
applying computerized high tech irrigation demands higher educated personel, so less chances for low educated people As applying
the technology is heavy work, this work is less appropriate for females
