Hello Mike,

You can easily approach this case in the following way:

  • Population of Dubai
  • Estimation of tourists in Dubai
  • Average water consumption per day. Be careful to consider substitutes (especially for young people) and the reduced water consumption for babies
  • Liters of water = # people * consumption
  • Average bottle capacity
  • # of bottles = Liters of water / average bottle capacity

I would skip the segmentation of the population by age in this case, since the water consumption per day is pretty much the same. I would just mention those 2 qualitative point when you have to estimate the average consumption per day.

Hope it helps,

Hey Mike, we must consider the impact of substitutes too (such as softdrinks, energy drinks, beer, etc...) which will reduce mineral water consumption in our case. To make the math simpler, i would say 10% (justify with a sanity-check) of our final number at step (4) is impacted by substitutes and give my final estimate accordingly.

Agree with Vlad, there are several posts like this -and btw, the approach is the same one for all-.

A good habit is to ask for help (not just in a subject line), and provide at least your ideas, so that we could give feedback
