Domestic Water Saving for Gardens
http://www.recyclingfactsguide.com/5-easy-ways-of-recycling-water
There are several easy ways of recycling water that the average consumer can do at home. These methods involve minimal cost and effort and can be implemented without a major disruption to the daily routine. If you are searching for ways of recycling water in your own home, here are some things that you can try.

If you rinse the dishes in your sink under running water, use a large plastic bowl or bucket to catch the rinse water. Though there may be small amounts of detergent in the water, this will not harm plants or the soil and the water can then be used to water plants or even for other cleaning tasks around the house.

When waiting for the water to warm in the shower, use a bucket to catch the cold water that is usually wasted down the drain. The water can be left in the bucket until needed for cleaning or gardening or can be pour into a large barrel outdoors to be used for tasks such as washing the car.

Leftover pot water from boiling pasta, vegetables and other food items can also be used to water plants. Be sure to give the water ample time to cool before pouring it onto your plants. Extremely hot water can damage more delicate plants and flowers.

When you clean out the fish tank or aquarium, use that water on your plants or garden. Though to you, the water might seem dirty, the waste from the fish is actually nutrient rich and can help plants to grow and thrive.

Consider redirecting the drain of your washing machine and catching the rinse water in buckets or barrels for reuse on your lawn or outdoor plants. This takes a bit more effort than the other ways of recycling water, but for those with a large lawn that needs regular watering, this can save a lot of water usage and waste.

There are other ways of recycling water, as well. Simply think about where water is wasted in your home and find a creative way to catch and reuse that water for other purposes. Though it will take many people joining in the cause to make a real difference in the state of the environment, by finding your own ways of recycling water, you can feel good about doing your part.

Arid Israel recycles waste water on grand scale (but not for the regions citizens?..."Competition over shared water resources is a sensitive issue in Israel's relations with the Palestinians and other Arab neighbors.")

Due to water scarcity in the region, Israel has become a global leader in water reuse technologies; more than 80 percent of household waste water is recycled.

By Reuters

Thirty years ago, Israeli farmers faced a daunting choice - find a new water source or go under. Their solution was waste water recycling. Now climate change is presenting other nations with a similar choice. With increased interest worldwide, Israel is marketing its waste water reuse technologies and has developed a billion-dollar industry by sharing systems and expertise. Israel began confronting water scarcity when its main sources, the Sea of Galilee and two aquifers, became overtaxed and the population was growing. There was simply not enough water for agriculture.

"We had to adapt, and found what at the time was an unlikely solution," said farmer Yaron Rot, who manages irrigation at Kibbutz Magen, an agricultural community in southern Israel. They began irrigating their fields with recycled waste water from the drains of Tel Aviv. At the time it was not discussed openly. Water treatment technology was not well-known and authorities feared the public would reject the idea ."Today, nearly half our irrigation comes from recycled waste water," Rot said, making clear it was no easy achievement.

By the turn of the century, Israel was still the only country to recycle waste water extensively. Global warming means its neighbors will increasingly need to do the same. Competition over shared water resources is a sensitive issue in Israel's relations with the Palestinians and other Arab neighbors. The United Nations, in its Human Development Report, classified the Middle East as the world's most water-stressed region. Its climate modelling projects hotter temperatures and less rainfall in the future. A separate UN report said the regulated use of treated water could reduce pressures.

"Israel demonstrates the potential," it said, adding other nations were following the lead of a country that has also pioneered water-saving techniques such as drip irrigation.

Israel has made water recycling an integral part of daily life - even if many residents are not aware of it. More than 80 percent of household waste water is recycled, amounting to 400 million cubic metres a year, the Environment Ministry says.

Treatment facilities remove contaminants to a level set by the Health Ministry and the water is then sent to farmers. Businesses have thrived by developing the most efficient solutions, including an ultra-violet light purifier and a recycling system that uses millions of small plastic rings to breed bacteria and break down organic waste. Exports of water-saving technologies total $1.5 billion a year, said Oded Distell, head of the government's water technology programme.

A government study also recommended the creation of wetlands to help treat waste water naturally. Such systems have been described as the "earth's kidneys" as they filter pollutants. Israel has built a few dozen manmade wetlands that treat sewage from cowsheds, vineyards and army bases, but this remains an area where it lags behind Western countries, said Michal Green, an engineer at the Technion Institute of Technology. Companies are showing more interest in constructed wetlands as an alternative to treatment plants, she said. "They are non-energy intensive, they have lower maintenance costs and they are a more aesthetic option. I have no doubt they will catch on."

The re-use of process and waste water - water recycling - an interesting solution

1. Tap and well water

The cost of tap water is constantly increasing. One pays now on average 1 - 1,50 EURO per cubic meter (1000 liters). This is a 20 % increase from 1990. Upon that, when extracting groundwater, a levy of EURO 0,15 - 0,20 must be paid. In the Netherlands e.g., due to a drop in the ground water level, concessions are rarely granted for the extraction of ground water anymore. This has resulted in more and more drinking water companies having to use surface water for the preparation of drinking water and companies changing to water recycling. It is therefore expected that drinking water will soon double in price. In the countries neighboring the Netherlands, high water tariffs are already in use. (Germany: EURO 2, - per m3, Denmark: EURO 2,50 per m3)

2. Energy savings with the water recycling

Many industrial processes require the process water to be heated or cooled. Well water and tap water have an average temperature of 10 C and 13 C respectively. On average, every degree rise in temperature costs around EURO 0,05 per m3. Every degree lowered in temperature costs around EURO 0,07per m3. By re-using process water, the energy requirement demands are lowered and therefore savings can be made on your energy expenses.

3. Further cost savings when re-using process water

When preparing process water, certain elements are removed to increase the performance of the system (e.g. the removal of iron from well water and the softening of water by the removal of carbonates). Apart from the removal of unwanted elements, other substances are usually added to improve the water quality and promote the effectiveness of the process (e.g. nutrients for plants in a horticultural nursery). When this water is re-used, it is free of unwanted elements and already contains those elements that are needed by the process, therefore lowering costs.

4. Stricter demands on water usage

Stricter demands are being made on the quality of the water flowing through processes. Disinfection by means of environmentally friendly products is highly recommended. Lenntech does not use chemicals (like chlorine or hypochlorite) for disinfecting purposes. Instead, Lenntech applies ultraviolet light and ozone which is very effective, yet harmless for the environment.

5. The costs of wastewater

The cost of draining off wastewater has risen by 20% in the past 5 years. This cost is expected to rise even more. Some companies have therefore already placed pre-treatment units for treating wastewater. In many cases, post treatment of the water is also possible, therefore making it suitable for water recycling in the process. The effluent water can also undergo a less effective treatment and be used as cooling or cleaning water. When none of the reuse options are chosen, Lenntech provides alternative methods of treating the effluent before draining. In this way the drainage tariffs are lowered.

The reuse of water concerning the above five points can save your company a lot of expenses.

Lenntech, having specialized in the research and design of effective and viable water treatment systems, offers you the solution to your water recirculation problems.
