# Cost Comparison - EZPack Storage system Vs Bottled Water

**EZPack Water Storage System**

The system is based on the following emergency operating concept:

- Water distribution stations based on EZPack bladders are deployed in the crisis area.
- EZPack truck modules are used for delivering water to the distribution stations.
- Flexups are used for carrying the personal water from the station.

**Cost Analysis Assumptions:**

- The calculation is for 100,000 people.
- Each person needs 6 liters per day.
- In the case of bottled water – 600,000 1-liter bottles would be required per day

- 25 distribution stations, each serving 4,000 people per day
- In the case of the EZPack Water Storage System – the volume of water storage needed per station is 24,000 liter.

- Filling water is transported to the distribution stations via trucks equipped with EZPack Water Truck models or F3DPacks. 2 models of the F3DPack are available: F3DPack 14 for standard flat-bed trucks can carry 14,000 liter; F3DPack 28 for flat-bed 18 wheelers can carry 28,000 liter.
- The stations are filled once a day, requiring two F3DPack 14 or one F3DPack 28 to fill the station.
- Each truck does 4 rounds per day – two F3DPack 14 can serve 4 stations per day; one F3DPack 28 can serve 4 stations per day.

**EZPack Water Storage System Cost Analysis**

- Equipment Cost per Distribution Station — assuming cost per liter of $5– is $120,000:
- The cost of F3DPack 14 is about $40,000; the cost of a F3DPack 28 is about $80,000; so the cost to purchase the modules for supplying the water is $500,000.
- A 6-liter Flexup costs about $3.50 and the Flexup can be reused during the event. However, since not all people will bring their Flexup for refill, (for events that last more than 5 days) we assume the number of Flexups needed to be 2.5 times the number of people served. That comes to a total of 250,000 Flexups at a cost of $875,000.
**The total cost of the equipment required to serve 100,000 people using the EZPack Water Storage System is $1,495,000. With $875,000 of the expenditure going towards wholly reusable equipment.**

**Bottled Water**** Cost Analysis:**

- Bottled water is trucked to the crisis area.
- The following table shows the cost of bottled water in response to a 1, 7, 10 and 14-day water crisis assuming a cost of $0.50 and of $0.40 per bottle:

**Total Cost****No. of People****Liter per Day per person****Total Liter Per Day****No. of 1 liter Bottles****Cost per Bottle****1 day****7 days****10 days****14 days**100,000 6 600,000 600,000 $0.50 $300,000 $2,100,000 $3,000,000 $4,200,000 100,000 6 600,000 600,000 $0.40 $240,000 $1,680,000 $2,400,000 $3,360,000 - The significant cost of collecting and disposing of water bottles varies between events. For long (> 1 week) events, these costs may reach several millions of dollars.

**Summary:**

- In both cases the cost of transportation is assumed to be the same.
- For a single (first) water crisis event, the cost of bottled water seems to be about the same for an event lasting 7 days or less.
- The cost of EZPack’s Water Storage System for a 7-day event is about 1/3 of the cost of bottled water, when factoring in equipment reuse.

- There is a clear cost advantage to EZPack Water Storage over bottled water for events lasting longer than a few days and for repeated events.
- The EZPACK Water Storage System cost advantage becomes even more significant when considering the following:
- For shorter events the number of Flexups is lower.
- The actual equipment cost is expected to be significantly lower than the conservative values used for this analysis.
- In most cases, the equipment will be collected and re-used for multiple events. For re-use (from the second event and on), without the initial capital cost, the per-event cost of the use of the EZPack Water System drops by almost 60%.
- When using bottled water, there is the significant additional cost of bottle disposal after the event.

**Conclusion**

The EZPack Water Storage Solution for water crises has better cost effectiveness over bottled water (especially overall cost for several events). In addition, it is a much more environment-friendly solution than bottled water.
