At the present time weirs have been established to determine 

 how much water is available from the various water sources 

 at different seasons of the year. It is quite possible that enough 

 water may be developed from the upland sources to enable the 

 installation of a direct gravity system for lloilo. 



The Guimaras project is an attractive one, because, if feasible, 

 it means a supply of water for lloilo at comparatively low 

 expense. The distance across the straits is something over 3 

 kilometers, but in spite of the added difficulty and expense in- 

 volved in piping the water under the sea, the estimated cost 

 of the Guimaras project is only about one-tenth that of the 

 Maasin enterprise. 



CONCLUSIONS 



The chemical character of the artesian waters is such that 

 their development as a source of municipal water supply does 

 not seem advisable. 



The Maasin and the Guimaras Island projects are both feas- 

 ible, so far as the quality of the water is concerned.
