Rainwater harvesting makes so much sense. Much of North America - indeed, much of the world- is struggling with drought, yet there is more than enough rain falling to solve the "crises" for centuries.
We have about twice the rainfall here in Nayarit that you enjoy, 35 inches last summer season, over 50 inches long-time average. The jungle seems to need about half of that; it takes that long to fully saturate the soil. Of course, our roofs, hardscape and road will not wait for saturation to start collecting. We are developing 7 lots and hope to provide rainwater for all, with the pond, one large central cistern of 50,000 gallons, and additional smaller cisterns on each lot. We will have a well (Plan B) and eventually, community water availability (10 years or so).
You are doing extremely well on usage at about 100 gallons per day. That's a quarter to a half of usage of most norteamericanos in the US. The best way to save water is not to need so much. Well done.
I do have a few questions, if you don't mind sharing.
1. Any palapa roofs needing aggressive chemical spraying yearly (contaminating runoff)?
2. How/where do you get water tested? Lab? Tested for pathogens and pollutants?
3. Did you select roof materials for non-polluting surfaces?
4. What water saving devices have you found most effective and trouble-free?
Thanks for the inspiration and for a demonstration of how to live more lightly on the land.
