The US$20,000 system
The actual hole with the pipe will cost between US$1,500 and $3,000. The rest is for the storage tank (10,000-20,000 gallons),the solar panesl,the pump and the distribution system. This systems will generally provide water to 100 families (maybe 500 people). USAID paid for the systems and the idea was people pay a small monthly fee and a mantainence program is set up with these funds. I can't really say how successful they have been. Most have been installed near Sosua, in the Northwest (Adesol) and in the South near Barahona (Fundasur). I think Tecsol also installed a few systems.
