Rain Water

Divert it to the desert!

You could bottle and export it (subject to stringent control).

use it for fresh water aquaculture and export the products.

Thanks Hendrik,

What shall be the best bottling processes for export? Export to what part of the world?

I recently bought a bottle of water from Fuji. Although it wasn't rain water, it came from an aquifer.

Are there other products on your island that could be bottled and sold? Such as fruit juices, coffee, or noni juice? You could use your water to make a marketable product.

A combination of your rainwater and sea water might create the correct environment for farming sea food, such as shrimp or crabs.

1. Accumulate in a reservoir

2. Use for general use, where no treatment is required

3. Store in a high reservoir and use to generate power

Caution:

Rainwater is pure water and should be treated as such. Perfect for washing clothes. May be the most pure available non-contaminated drinking water but will provide no minerals to the diet.

Accumulated standing water can provide breeding space for mosquitoes and spread marlaria in some global locations. Keep stagnant water covered aeriated or circulated.

Cornstoves : Rain water is not completely a pure water. Such contamination from atmosphere depends on the located area.

Agreed.

The purest water, indeed the purest substance in the universe, is the ultrapure water used in the washing of silicon wafers in the microelectronics industry. Impurity levels are in the fractions of parts per 10⁹.

Rainwater impurity certainly varies with the atmosphere through which it passes (particulates, SOx, NOx, birds, insects, aeroplane emissions, etc.)

"...purest substance in the universe" ? Now that is what I call a bold statement !

Put up big solar pwered fans and blow the rain twards Australia they need all the rain they can get. If the will not get approval send it by sea in big tankers. I am sure you will get rich very slowly due to the high cost of shipping these days.

But you will gain many friends. Shouild you want a local use for this abundant supply, you could always turn it into hydrogen and oxygen then run big fuel cells and get electricity in return may be enough to keep the cycle going. Perpetul motion?

There again you could dig a big hole and breed fish to eat; have an olympic size swimming pool, or simply let some one else do the hard work while you sit back and enjoy a cool beer. There must be a hundred and one things to do with rain water.

Only remember it is unlikely to be very pure. Disolved gasses such as sulpher dioxed, carbondioxed, nitrogen oxides all disolve into rain water, dust gets swept up into the air and rides in rain clouds. Radio active isotopes to, and all that volcanic pollution as well.

Store it in the cheapest and biggest container available and use it for everything exept potable water. If you want to drink it, run it through a carbon filter chlorinate it to 1ppm and store it in another tank and take it from there through another carbon filter at the tap to remove the chlorine then drink it.

Rain water has whatever it has scavenged from the air in it. And if it came from your roof it could shit from wildlife as well.

Do you have ground water on your island?

Here in Bali I pump my surplus rainwater back down into the aquifier I pump out of.

Result: more balanced groundwater and less chance of seawater fissures (like in Surabaya, where the ground water is basically useless).

Saves the cost of a tank and mostly, you don't even need the pump.

They do this in South Australia with treated grey water.

Being on an island your pollution levels should be low.

your first step should be to have the rain water and other sources the water analyzed.

Filling big containers would be the cheapest but legislation differ in different parts of the world. (In South Africa bottled water products must be bottled on the site where it is found.)

I would presume that Europe around the Mediterranean may be the best market (because of the higher levels of pollution in their natural resources).

With the expected pureness of the water you may start a new industry by supplying hair wash/rinse water in 5 litre containers. market research will be required.

Your best bet however may be to produce something with the water (or mixture). (aquaculture, crop or animal).

I use it to flush my toilets and as water for garden use. (pond, swimming pool, auto, animals,...)
