Learn about World Water Day 2014

Each year on March 22, World Water Day attracts international attention to the conservation and development of freshwater resources.

Water and energy are closely linked. Energy has different forms, and water is crucial to produce, transport, and use all forms of energy to some degree, and these activities have different impacts on water resources.

Water requires energy, and energy requires water. Water is required to produce nearly all forms of energy. Energy is needed at all stages of water extraction, treatment, and distribution.

Supplies are limited, and demand is increasing. Demand for freshwater and energy will continue to increase significantly over the coming decades. This increase will present big challenges and strain resources in nearly all regions, especially in developing and emerging economies.

Saving energy is saving water. Saving water is saving energy. Choices concerning the supply, distribution, price, and use of water and energy impact one another.

The “bottom billion” urgently needs access to both water and sanitation services, and electricity. Worldwide, 1.3 billion people currently live without electricity, 780 million people lack access to safe drinking water, and 2.5 billion people are without sanitation. Water and energy have crucial impacts on poverty alleviation.

Improving water and energy efficiency is important. Better understanding between the water and energy sectors of the connections and effects on each other will improve coordination in energy and water planning. Policymakers, planners, and practitioners can take steps to overcome the barriers that exist between their respective domains. Innovative and practical national policies can lead to more efficient and cost-effective water and energy services.

CDC's Global Water, Sanitation, and Hygiene (WASH) Expertise

Inadequate water, sanitation, and hygiene (WASH) conditions exist in a range of settings, from temporary refugee camps to entire neighborhoods in large cities.

Since 1990, the number of persons able to access improved drinking water and sanitation resources has increased by 2 billion and 1.8 billion respectively. Despite these gains, hundreds of millions still lack access to these essential resources. Diarrheal diseases, mostly a result of unsafe water and inadequate sanitation, account for 1 in 9 child deaths worldwide. In 2010, over 800,000 children under 5 years of age died from diarrhea, making diarrhea the second leading cause of death among children under the age of 5.*

CDC's global WASH work involves partnerships with other US government agencies, ministries of health, non-governmental organizations, UN agencies, private companies and various international agencies. Our program provides expertise and interventions aimed at saving lives and reducing illness by improving global access to healthy and safe water, adequate sanitation, and improved hygiene. The WASH program works on long-term prevention and control measures for improving health, reducing poverty, and improving socioeconomic development as well as responding to global emergencies and outbreaks of life-threatening illnesses. These improvements reduce the lethal impact of WASH-related diseases ranging from cholera to typhoid fever to hepatitis.
