No mere pipe dream
UCI engineers are working on robotic technology to rehabilitate the nation's aging water infrastructure.
The growing U.S. infrastructure crisis involves more than crumbling roads and bridges. Underground and out of sight looms a worsening problem every bit as critical.
Thousands of miles of aging water pipes are breaking down. Each day, according to the American Society of Civil Engineers —

Bottled waters has lightest environmental footprint
A new study finds that water, in all its forms, has the least environmental impact of any beverage choice. And when compared to other packaged beverages, including soft drinks, sports drinks, enhanced waters and juices, bottled water has the lightest environmental footprint. ... read more >>
Optimal Location of Created and Restored Wetlands in Mediterranean Agricultural Catchments
Simple tools and accessible information are needed by environmental planners to select sites for the restoration or creation of wetlands. A flexible suitability model for allocating wetlands is demonstrated in small (20–2,000 ha) agricultural catchments in the semiarid Ebro basin (NE Spain). The model used improved existing data layers (soil and geomorphology), simple geographical transformations ... read more >>
Map: Total Water Use per capita by Country
This map shows total water withdrawal per capita by country. Water withdrawal is the quantity of water removed from available sources for use in any purpose. Water drawn-off is not necessarily entirely consumed and some portion may be returned for further use downstream.
Current world total water withdrawal: ~499 m³/inhabitants/year ( 499,000 liters each person )
Annual quantity of freshwat

Freezing supercooled water puzzles scientists
As every schoolchild knows, water freezes at 0°C. Or perhaps not. It has been known for centuries that pure water, in the absence of any nucleating surface, can remain in a supercooled liquid state down to temperatures as low as -40°C. Now, researchers in Israel have discovered that supercooled water itself will freeze at different temperatures depending on whether it is in contact with a positiv ... read more >>
Environmental Life Cycle Assessment of Drinking Water Alternatives & Consumer Beverage Consumption in North America
Nestlé Waters North America (NWNA) has commissioned a project to better understand the environmental aspects of bottled water and available alternatives, and to explore ways to further reduce its own footprint. The intentions of the project are to 1) identify and compare the environmental impacts of consuming bottled water and several prominent alternatives; and 2) identify the environmental impa ... read more >>
Map: Freshwater Use as Percentage of Total Renewable Water Resources
This map shows worldwide surface water and ground water withdrawal as percentage of total renewable water resources. Water withdrawal is the quantity of water removed from available sources for use in any purpose. Water drawn-off is not necessarily entirely consumed and some portion may be returned for further use downstream. This parameter is an indication of the pressure on the renewable water ... read more >>
Chart: Surface Area of the Earth
This chart shows total surface area of earth.
Total surface area of earth: 510,072,000 sq km
* Total water surface area: 70.8% (361,132,000 sq km)
* Total land surface area: 29.2% (148,940,000 sq km)
There are a total of 5 oceans, and they are the Arctic, Pacific, Atlantic, Indian, and the Antarctic Ocean. Out of these five, there are three major oceans, the Atlantic, Pacific, a
