Almost all of the water that has ever existed on our planet is the same water we see today, 97% of which is non-potable seawater. The remaining 3% is freshwater, mostly locked in ice caps, glaciers and the ground. Only a fraction of a percentage is the surface water we typically depend on. To put it in perspective, if all of the Earth’s water were condensed down to fit into a single gallon jug, the freshwater readily available for our use would only equal about one tablespoon.
Standards & treatment considerations for rainwater harvesting systems
Aaron and Rebecca Howald of Franklin, Tenn., are busy professionals — she an attorney and he an executive for a national building products company. Their home site outside of Nashville might not have been buildable were it not for rainwater harvesting — it is distant from municipal water supplies, and wells in the area can be problematic.

New filling stations allow trucks in San Jose and Milpitas to use recycled water
As one more step to conserve precious drinking water, San José’s (Calif.) Environmental Services Department is making recycled water from its South Bay Water Recycling (SBWR) system available at truck fill stations for three approved uses: construction trucks that spray water to keep down dust at construction sites, city trucks that perform sewer cleanouts and street sweeping trucks that mist the street surface as they sweep.
Water storage in California's Sacramento and San Joaquin river basins was 11 trillion gal below normal seasonal levels
It will take about 11 trillion gal of water (42 cu km) – around 1.5 times the maximum volume of the largest U.S. reservoir – to recover from California's continuing drought, according to a new analysis of NASA satellite data.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Approximately 96 million gpd of wastewater is treated into drinking water
There are many examples across the U.S. of local water utilities taking progressive steps to create a drought-proof sustainable supply of water to meet public, agricultural, industrial and environmental demands. These include Wichita Falls, Texas; Palm Beach County Utilities, Fla.; and LOTT Clean Water Service in Oregon.
Water scarcity is a universal and growing issue. With huge projected population growth, this problem will only continue to increase. The World Economic Forum reported that the world’s population surpassed 7 billion in 2011, and is expected to reach 9.3 billion by 2050. Urbanization, industrialization, pollution, increased energy needs and climate change all reinforce the stress of population growth, making water accessibility an even more pressing issue.

Two innovative projects produced food and beer for gala celebration
The WateReuse Assn. recently honored two creative partnerships that demonstrate how agencies, industries and producers can work together to increase water resources to meet public demand. The awards were presented during the One Water Innovations Gala in New Orleans on Sept. 28.
This article will review the benefits and challenges of implementing water reuse strategies, focused on building heating, ventilation and air conditioning (HVAC) and plumbing systems at the new 217,000-sq-ft Milton Union K-12 School. Public policy changes (codes, etc.) needed to be addressed during a project to more readily integrate these strategies into the building design. A summary of the water savings associated with incorporating these strategies is described herein.
K-12 school uses rainwater for toilet flushing & irrigation
Commercial applications for harvested rainwater are no longer a rarity in the U.S., though few uses of this heaven-sent water match the AdvancED facility in Alpharetta, Ga., for sustainability and energy efficiency. The U.S. Green Building Council thought so, too — the new global headquarters facility earned LEED Gold status.
