I agree 100 percent that water limits growth. I saw it where I moved from with government limits on water usage.
They can always build another coal fired power plant, but water is a much harder resource to produce when not enough falls from the sky or is stored when it does fall. The ancient Romans were better at water management than modern Dominicans are.
I agree, you can use only so much as you physically get it, but I think much more could be done in controlling the usage of it, none of which takes place properly in my opinion.
1. Water meters
2. Proper plumbing without leaks for starters...
In Europe, it's normal to a person use about 150 liters of fresh water daily (and where there is normally no shortage of water because also ground water is used and because everyone pays for every drop they use), which number is increased a bit if you have a garden etc. Based on all my calculations and what I have seen, The areas in the DR that receive water, use the multitude of this amount on a daily basis, while the "affected areas" received much less... So when there is street water available in many barrios in the DR, which is obviously not metered, everyone just takes a hose and starts to shoot out water everywhere and wash their cars etc etc. All this water is usually wasted...
