Water is the origin of life and precious resources to us. For the purpose of getting water, communities were composed, farming managed, and manufacturing done. And stable supply of water has helped progress of agricultural techniques, development of industrial economy, and improvement and conversion of industrial structures.

In order to get water resources, we can make the following statements.

  1. River water 
  2. Water from lakes, marshes, and reservoirs  
  3. Rain water 
  4. Water from underground and spring  
  5. Reutilization of water 
  6. Replacing sea water to fresh water, etc.

In order to get water resources in the isolated islands and the top of depth of mountains, utilization of rain water and spring water is easy and economical.

We had investigated and studied to get and stabilize the supply of rain water at the isolated islands of Tokai district in Japan. Besides we devised an apparatus by solar energy .(not by commercial energy) available for the isolated islands. The outline is following:

  1. Quantity and quality of rain water  
  2. Collecting works of rain water 
  3. Solar cells and pump facilities  
  4. Water supply apparatus 
  5. Sterilizer
