Getting into hot water
An analysis of the engineering and economics for a solar water-heating system shows it to have a payback period of just two years, according to researchers in India. They report, in the International Journal of Global Energy Issues, on the success of the 1000-liter system operating at a university hostel. view more (2009-03-09)
GROWing the next generation of water recycling plants
A vegetated rooftop recycling system has been developed that allows water to be used twice before it is flushed into the communal waste water system. view more (2005-12-09)
Pure water without electricity
Many a visitor to Majorca - the island of choice for German and British vacationers - has made the bitter experience: The drinking water in some parts of the island is unbearably salty. Naturally, water treatment plant operators make a concerted effort to lower the salt and lime content of their water to acceptable levels by mixing in fresh water.... view more... (2002-07-22)
The Romans preferred small-scale solutions to aqueducts and sewers
Contrary to common opinion, the Romans had several systems for the supply and drainage of water. The Romans preferred small-scale provisions such as cesspits, wells and rainwater tanks. The residents only constructed a water supply network or a sewerage system if these were not effective. Research carried out at the University of Nijmegen reveals... view more... (2002-06-24)
New study of solar system speculates about life on other planets
A comprehensive review by leading scientists about our Solar System which speculates on the possibility of life on other planets has been published. view more (2006-09-13)
Scientists Discover How Fish Evolved To Float At Different Sea Depths
Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths. view more (2005-03-18)
2002 Stockholm Water Prize Winner Announcement
The recipient of the 2002 Stockholm Water Prize, the leading international award for outstanding achievements on behalf of the world's water, will be announced in Stockholm on March 22 in a press conference at 11.00, Central European Time. The $150,000 Stockholm Water Prize is being presented by the Stockholm Water Foundation for the 12th time.... view more... (2002-02-04)
Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
Cooling milk using sun energy
The company Tarre of Navarre, Basque Country, in collaboration with the Public University of Navarre has built a prototype for cooling milk. This cooling and maintenance system takes the energy directly from a photovoltaic system and so there is no need to use batteries. The prototype integrates two concentric cylindrical tanks in a single... view more... (2002-12-03)
Step on the gas — New fuel cell design adds control, reduces complexity
When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas - hydrogen gas, to be exact. view more (2007-01-17)
European Water Directive: Optical sensors detect minute amounts of pollutants
Minute amounts of organic pollutants-including oestrone-can now be detected in river water as a result of a new optical sensing instrument realised in a project funded by the EU's Environment Programme. view more (2004-09-01)
Novel bacterial strains clear algal toxins from drinking water
Novel bacterial strains capable of neutralizing toxins produced by blue-green algae have been identified by researchers at Robert Gordon's University, Aberdeen. view more (2009-09-08)
Subproducts resulting from disinfecting drinkable water
For his PhD thesis, Unai Iriarte Velasco analysed strategies for reducing levels of subproducts from the disinfection of drinkable water and their application in optimising the functioning of water treatment plants. view more (2005-09-09)
Midwestern ethanol plants use much less water than western plants, U of Minnesota study says
Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows. view more (2009-04-15)
New surprising results about the research on glaciers
In order to understand the dynamics of glaciers and ice sheets as well as their interactions with climate, we need fundamental detailed knowledge about the way in which glaciers and ice sheets move. The way water is routed through glaciers is highly significant for their movement since the water pressure at the base of the glacier directly... view more... (2005-02-09)
Nominations sought for 2001 Stockholm water prize
Institutions, Organizations, Individuals and Companies Eligible for $150,000 Prize (STOCKHOLM, SWEDEN) Nominations for the $150,000 international Stockholm Water Prize, which is presented annually for outstanding contributions to the conservation and sustainable use of the world’s water resources, will be accepted until September 31, 2000.... view more...

Recycling water in buildings by microbes
New information about how households and businesses can recycle and re-use their own water suggests that a submerged membrane bio-reactor could be the best method. The aim is to make water a more sustainable resource by reducing the amount that needs to be treated by large, central facilities. The work is being carried out in Cranfield... view more...

New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes... view more...

Watching over the water system
After a big earthquake, it's key to keep the water system afloat. Water is necessary for life, and it fights the fires that often accompany such disasters. view more (2009-08-19)
Fuzzy logic water quality
A fuzzy logic approach to analyzing water quality could help reduce the number of people in the developing world forced to drink polluted and diseased water for survival. view more (2008-04-18)
