Under pressure from such factors as population growth, climate change, depletion of groundwater resources, and impacts from salt, many communities are struggling to find enough water to meet their needs. Water Reuse and Desalination will continue to grow in the United States and around the world as they become increasingly recognized as reliable, safe alternative sources of supply.
Although the planet Earth is mostly water, approximately 97.2% of this precious resource is saline and only about 2.5% of it is classified as fresh water. Approximately 70% of the fresh water is locked up in the form of polar icecaps and glaciers. The remaining groundwater or surface water (0.7% of the world’s water) often does not meet the needs of local populations.
