Interior Dept. releases progress report on U.S. Water Census
The U.S. Interior Department issued released a report to Congress on the progress of the National Water Census. As competition for water grows — for irrigation of crops, for use by cities and communities, for energy production, and for the environment — the need for the National Water Census and related information and tools to aid water resource managers also grows. The Water Census will assist water and resource managers in understanding and quantifying water supply and demand, and will support more sustainable management of water resources.

Water treatment plant ozone upgrade wins civil engineering award
The Ozone Upgrade and Expansion Project of the Alvarado Water Treatment Plant in San Diego, California, was named the winner of the American Society of Civil Engineers (ASCE) 2013 Outstanding Civil Engineering Achievement (OCEA) Award. In addition to expanding plant capacity by 67 percent, the city of San Diego converted from chlorine to ozone disinfection. The incorporation of ozone enabled the city to provide not only safer water with lower levels of carcinogenic disinfection by-products, but also water that is odorless and better tasting.

The ground is key to cleaner environment, water
While many people recognize that clean water and air are signs of a healthy ecosystem, most do not realize that a critical part of the environment is right beneath their feet. The ground plays an important role in maintaining a clean environment by serving as a natural water filtration and purification system.

Old, faulty bores jeopardize Australia's water
Australian homes, towns, cities, farmers, and miners will rely increasingly on underground water as the country’s population grows, surface water supplies dwindle, and as droughts multiply under a warming climate. Trouble is, the authorities in charge do not have a clear idea exactly how much groundwater there is, how rapidly it is recharged — or how quickly it is being depleted. What is known is based on data largely supplied by 23,000 monitoring bores spread across the continent — more than two thirds of which are now falling into disrepair.

Farmers upset by plan for water banking system
Depending on the depth of the drilling, it can take anywhere from two gallons to two million gallons of water to frack one well; drilling companies consumeenough water in their fracking operations to meet the needs of between 66,400 and 118,000 households; in the parched Midwest, farmers raise questions about water-use priorities

Engineers solve leaky water pipes problem
Leaky pipes are a common problem for the water industry: according to the U.K. Water Services Regulation Authority (OFWAT), between 20 and 40 percent of our total water supply can be lost through damaged pipes; developing more accurate ways of finding leaks would enable water companies to save revenue and reduce their environmental impact

Groundwater pumping causes sea level rise, canceling out effect of dams
Those in charge of infrastructure protection must now worry about another source of sea level rise: water pumped out of the ground for irrigation, drinking water, and industrial use; this water ends up emptying into the world’s oceans, and scientists calculate that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year
