4: Water Quality
A Water Quality Argument
For Rain Water Catchment Development In Belau
University of Guam, USA
Summary of Problem.
The quantity and quality of fresh water for human use has been a critical area
of development in the Republic of Belau, formerly Palau, in the Western Caroline
Islands. In an area which receives about 3 810 mm (150 in.) of rainfall per year,
development of water resources has lagged behind demand and use. The primary emphasis
for the last thirty years has been on the development of a centralized water system
utilizing the impoundment of surface water. Resulting water hours from an insufficient
quantity of water and delivery problems plus poor quality have limited the effectiveness
of the municipal system in meeting the needs of the consumer. Because of these
quantity and quality problems, rain water has been extensively utilized for human
consumption. Yet, there has been little organized effort to develop this resource
beyond a rudimentary level. Thus, rainwater catchments are often inadequate during
certain times of the year.
With increased growth and development and a need to be self-sufficient, a sound
water resources development policy that include rainwater catchment should be
considered for the Republic of Belau. The high quality of rainwater in this geographic
area should be an important actor in this choice.
