Problems in Developed and Developing Countries Developed countries- having the technology and water management organization to support a higher standard of living based on a high rate of water use -water withdrawals becoming so high that even these facilities cannot keep with the demand. Developing countries-lacking the facilities to properly treat and distribute the water resources within their reach
