Desalination Plants, coupled with water reservoirs are the best options for Haiti.

La Gonave lacks water, much like many parts of Haiti, there is no water.  Ironically there is a tremendous amount of water surrounding the country.  For the most part, the sea water doesn't help the country solve the dire water conditions.

One major way to fighting hunger and chronic drought is to put desalination plants on La Gonave that can be powered by solar power.

Systems like the one above can produce 12,000 gallons of water per day.  These systems can serve the citizens drinking water needs.  Given that many parts of the land on La Gonave has some pollution issues from raw sewage, or bad terrain, building a small system that can pull water in from the ocean, and then pump that fresh water into a holding system is one of the best ways to have long term water solutions.

Building large reservoirs in the city of Anse-a-Galets would be critical in addressing the water issue for citizens.  In fact many American cities, such as Seattle used water reservoirs that were constructed to serve citizens drinking water. (see below)

  The is a reservoir that was built in the Roosevelt community of Seattle.  

This would serve the citizens drinking needs, but also there is a need to address farms that are outside of the city.

Having a smaller portable desalination plant can be used, along with long water channels could help bring rice farms back on line as well as producing a large amount of crops.

Keep in mind a 500 gallon per day desalination system costs less than $10,000 US.  Even a 230,000 gallon per day system is under $300,000 US.

Building a reservoir made of a rock base, with a rubber liner can be built very economically, with new reservoirs in other cities.

Farming communities could work with the below setup.

Having a long water canal, similar to a highway, could go across parts of the island.

This type of system would allow for good rice farming communities, as well as a fish and shrimp operations.  These canals are built out of the ground with no liners, but have a constant amount of water flowing through them.

Eventually the unused water would flow back into the sea, and then the process continues.

The lack of water is a grave concern, but it can be fixed.  Water canals would form the highway, and veins or irrigation canals could then be built from the main canal linking it to various farms that need water to their land.  Imagine having small pumps that can then pump water directly to farms!

Go Gonave!
