#Tackling fresh-water shortage problems around the Mediterranean Water is the most vital resource for human life.

A European research project has developed a transport system consisting of water-bags and tugboats to bring fresh water to the hardest-hit coastal and island regions around the Mediterranean.

Areas under increasing pressure from water scarcity, particularly in the summer months, include small cities and islands along the coasts of Spain, Greece and Italy

and island communities around the Mediterranean are affected by water-stress problems. According to the European environment agency (EEA), 16 to 44 million additional people will suffer water scarcity in Southern Europe by 2070.

Coastal and island communities are facing serious water shortages, made worse by the annual influx of tourists.

To meet growing demand for water in this region an innovative, flexible and affordable solution is needed to transport large quantities of fresh water from ater-richto ater-poorareas.

The EU-funded Refresh project has come up with such a solution. The research team has developed

and cost-effective system to transport fresh water by sea using flexible plastic containers water-bags towed by a tugboat.

the Refresh prototype water-bag was towed successfully for 16 nautical miles on a voyage back and forth through the Gulf of Souda, off the island of Crete.

The Refresh water-bag is a composite of modules which can combine to form a 20m-long,

4m-wide container capable of carrying 200 tonnes of fresh water. Each water-bag is equipped with integrated sensors,

powered by a solar cell located on the flat top of the container. A fibre-optic grid monitors any deformations in the bag (signs of tearing

A water quality sensor to assess water purity has been tested in a laboratory with the intention of being fitted to water-bags in the future to ensure safe and clean delivery after transit.

The primary application of the Refresh water-bag and delivery system will be to supply fresh water to Mediterranean coastal cities and islands with less than 300 000 inhabitants covering about 45 million European citizens.

Around 65%of the communities in these coastal cities and islands double in size during the tourist season.

With the initial investment focused mainly on constructing the water-bag and renting or purchasing a tugboat,

the Refresh approach is more cost effective than using tanker ships where fresh water is priced around EUR 14/m3 or huge infrastructures, such as pipelines or desalination plants.

and selling the water-bag system to third parties or from directly operating the water-delivery service by setting up a joint venture,

says Samuele Ambrosetti, leading engineer on the Refresh project. ocal operators will have the possibility of buying

or renting the water-bags from the consortium or of procuring the urnkeywater-transport service.

The final price for the water will depend on the distance it is shipped and on the payload.

Preliminary calculations indicate water costs of around two to five euros per cubic metre for intra-Mediterranean voyages,

where each water-bag module is 5 metres long and 4 metres and holds 62.83 cubic metres of water (with total water costs between EUR 126.66-314.15 for such a journey),

The supply of fresh water to locations experiencing shortages will help take the pressure off aquifers and reservoirs,

and to form partnerships to deliver water, says Mr Ambrosetti. ontacts are ongoing with potential commercial partners in the USA and Middle east.

The BIFIPRO system releases copper and silver ions into the water to eliminate biofilm a breeding ground for harmful bacteria like legionella.

The quantities released into the water are known immediately while the dosage can be adjusted remotely if need be.

Before the development of the SILCO (r) sensor water samples needed to be taken and analysed over a number of days thus making the entire process considerably more complex and expensive.

It demands a lot of sun, good soil, water and cold temperatures. But how do you install an environmentally friendly and sustainable cooling system in a country so warm?

Next, a 200-metre chain is dropped into the water. At the end of the chain is a 30-metre-wide sea anchor that opens under water like a parachute both slowing down the drifting ship and turning it 90 degrees.

With the wind and waves now in parallel to the ship instead of hitting the ship from the side the rolling motion is reduced greatly.

#New Water-Saving Technologies Help Weather Drought but More Innovation Is needed Here in California, people are cheering from one end of the state to the other.

But unlike today, very stringent water restrictions much more severe than any now in placewere impacting residences as well as commercial facilities.

For instance, some households in Marin county, just north of San francisco, were restricted to 44 gallons of water per person per day0 gallons less per day than normal usage.

Businesses and commercial facilities were asked to reduce water consumption by 57 percent. While many complied,

Water use soon returned to normal. But just 10 years later, the state was hit with another very dry period,

These innovations not only reduce water consumption but have helped people in California and around the country become much more conscious of their water consumption.

Leadership, Planning, New Technologies Public and business leaders over the years have developed ong-termwater conservation programs for California residents

and have been so successful that many areas of the state are using about the same amount of water today as they were 10 and 20 years ago, even with population growth.

We also have many new water reducing technologies today that were likely not even considered 40 years ago.

or similar devices to restrict the amount of water released from faucets. Today, the installation of aerators is one of the most significant and inexpensive steps a commercial facility can take to reduce water consumption.

The typical faucet releases about three gallons of water per minute; with an aerator installed,

this can be reduced to as much as 0. 5 gallons per minute. In the 1970s, 80s,

and early 90s, toilets typically used more than three gallons of water per flush, sometimes as much as five.

and the country early two billion gallons per day across the countryand save a family of four, on average, $2, 000 in water bills over the lifetime of the toilets, according to the EPA.

urinals used 2. 5 to more than three gallons of water per flush. Now low flow urinal systems release about one gallon of water,

and no-water urinals use none whatsoever. Here in California and around the country, they are found in office buildings and schools, even very high-end hotels.

Finally, for commercial facilities with landscaping, automatic drip-type irrigation systems another new technology are helping consumers

and building owners reduce water consumption considerably. With these systems, spray heads are eliminated and water is delivered directly to the roots of plants and vegetation.

Some of these systems also come with ainand soil moisture sensors so that irrigation is released only when and as needed.

#Biochar changes how water flows through soil Rice university rightoriginal Studyposted by Jade Boyd-Rice on September 25 2014new research could help settle the debate about one of biochar s biggest benefits#its seemingly contradictory ability

or biochar to soil to both boost crop yields and counter global climate change the study offers the first detailed explanation for this mystery. nderstanding the controls on water movement through biochar-amended soils is critical

and gardening buffs took off after archaeological studies found that biochar added to soils in the Amazon more than 1000 years ago was still improving the water-and nutrient-holding abilities of those poor soils today.

either increase or decrease the amount of water that soil holds but it has been tough for experts to explain why this occurs due partly to conflicting results from many different field tests.

In the new study biogeochemists at Rice conducted side-by-side tests of the water-holding ability of three soil types#sand clay and topsoil#both with and without added biochar.

For scientific studies it is critical to make sure you re comparing apples to apples. arnes says the team chose to make its comparison with simple relatively homogenous soil materials to compare results to established hydrologic models that relate water flow to a soil s physical properties like bulk density

but in fact researchers have found that biochar-amended sand holds water longer. tudy coauthor Brandon Dugan assistant professor of Earth science at Rice says e hypothesize that this is likely due to the presence of two flow paths

for water through soil-biochar mixtures. One pathway is between the soil and biochar grains

and a second pathway is water moving through the biochar itself. arnes says the highly porous structure of biochar makes each of these pathways more tortuous than the pathway that water would take through sand alone.

and further slow the movement of water. y adding our results to the growing body of literature we show that

The device harvests energy in any location where these temperature changes naturally occur powering sensors that can check for water leaks

or inside a wall and sensors would be tuned to check for water leaks. Similarly when used inside a bridge the sensors could detect any cracks forming or structural deficiencies.
