water recycling with a gray water system
addition of rainwater harvesting can also be a part of domestic sewage, the Grey water is recycled. Grey water is low polluted water such as showering, bathing, and washing hands is obtained. This water can be washed after treatment to flush the toilet, brushing your clothes, or used for garden irrigation.
How great is our water consumption?
The water consumption in Switzerland is 162 liters per person per day. Of these, only 5.4 liter for drinking or cooking be used. In relation to other countries, water consumption in Switzerland is relatively high. This is probably also the large amounts of available drinking water and the favorable Water prices together. While in Switzerland, a constant supply of clean drinking water is taken for granted, have about 20% of the world's population lack access to safe drinking water.
How does a gray water system?
There are several manufacturers of gray water recycling systems. In the following I am concerned but with the installation from Mall environmental systems AG.
The facility itself is located in a two-chamber shaft. In the first chamber, the gray water is collected and purified. Then the water is pumped into the second chamber. This chamber is the clear water chamber and serves as the stack container. From here, toilet flushing, washing machine or the garden are supplied with tap water. Should there be enough water in the clear water chamber, water is automatically fed into the tank.
order to rot the standing water and not stink begins to be pumped from time to time, compressed air into the water. Almost all the technology is in the tank. Only the controller should be installed in the building equipment room. It would also be possible to plant instead of a tank in the garden, to install in the basement. This would be costly, because it would have special plastic tanks are used. Moreover, the advantage of underground facility that is necessary in the building, no additional space.
How clean the gray water?
The purification of greywater is in 3 steps: 
Mechanical cleaning: The water flows first through a Spaltsiebfilter. In this case, particles which are larger than 0.8mm hang. Here, hair and nail sections are filtered out. Later, you will then flow through an overflow directly into the drains.
Biological purification
The second stage is the biological treatment, which comes from a family of microorganisms. Here the water is cleansed of the microorganisms by feeding on the dissolved organic matter in water. The organic substances oils, soaps, skin flakes and care products like shampoo. germs and pathogens are removed in the membrane filter, because the bacteria are larger than the pores of the membrane filter.
worth Where is the use?
A cubic meter of treated water costs about 6.00Fr. Since the water in Switzerland is very favorable, there is a worthwhile investment only where a lot of water accumulates. A cubic meter of water, so 1000l cost in the city of Zurich on average 2.50Fr.
Examples of integration are:
- Sports facilities: There is a shower especially after exercising. Use for toilets, watering lawns etc. - multi-family homes or large housing developments: Several parties produce much Gray water. The cost of the system can be shared. Water use: toilet flushing, washing machines, garden tap, etc.
advantages and disadvantages of greywater
+ Protects drinking water resources + gray water is always available.
+ sewage treatment plant is less impact - pays off in the U.S. only at much water - elaborate plumbing, as separate systems

reflection of the work - Addendum
is always talking about saving water . It is only a short shower and the water in the soap The engines. These and many other tips to be an indoctrinated from an early age.
I was wondering why we do not then inserting more gray water systems to conserve water. How ever does such a system?
think retrospectively I erscheckend how much water we drained out every day without being used. What is clear is that we here in Switzerland with plenty of fresh clean water and good luck. Would still useable should we conserve resources and save water.
For large housing developments that could certainly happen with a gray water system, since costs could be shared. Everyone would pay only a little more. But 50% water . Save When I find a house plant is good, but in proportion too expensive. Maybe you could start to drink here instead of mineral water Hanenwasser because tap water is 90-1000 times more environmentally friendly than bottled water.
