3 P redfiltriranje is the best way to ensure the quality of rainwater. Rainwater has already come i

This one publication at the end of 2013, slightly modified, because I'm the year of application noted some improvements :-) If you use rainwater for flushing cisterns, watering and washing, is all this philosophizing slightly less important, but only slightly. In our aim was drinking rainwater, game kapal perang although we do not drink. This is because I realized game kapal perang that this is the dozens game kapal perang with relatively little effort. In Slovenia, the data on this quite a bit, the best information is found in countries where water is scarce. The system aims to minimize the effort of maintenance spending game kapal perang could be standardized and inexpensive to obtain safe drinking rainwater. The purity affect different parts of the chain.
1 Tiles should be smooth game kapal perang (on rough is kept more dust), clay or concrete. Roofing materials such as asbestos, Tegola, sheets, they are less suitable for the collection. I agree, that sounds logical. On the Australian side have experimented and concluded that the quality of much more affected by dirt on the roof (ie smoothness), rather than the type of material. The purity of rainwater should not significantly affect either bitumen game kapal perang and asbestos sheets, which are their may also be suitable. Well, if the drought is all good :) I do not use it, but if you pay me.
2 Gutters should be made of material that does not affect the water - not copper, or galvanized - for the same reason decking should not be tin, whereas metals leach into the rain and stay there. What do you say Australians for materials already know :) But I also know that the human body of heavy metals can not be removed, it just builds up and the long-term use are familiar with changes in health. ZRMK recommended gutters of plastic or stainless materials. Neither the one nor the other but not too aesthetically pleasing, if you ask me. Painted game kapal perang aluminum gray zone, and so far the most inclined to. Unless I find a nice imitation plastic. Note 2013: In the end, we installed galvanized painted sheet metal.
3 P redfiltriranje is the best way to ensure the quality of rainwater. Rainwater has already come into the tank clean. Anything game kapal perang else is a compromise. That's my argument is supported by the Australian English mentality :) Rainwater is essentially cleaner than groundwater, game kapal perang which may also contain environmental contaminants'' modern'' society (pesticides, phosphates, nitrites ...). The problem of rainwater are:
A) purity of the atmosphere: dust and other small particles in the atmosphere game kapal perang may be having long periods of drought so dense that it is impossible views. We know that when it rains washed out, you can see the Goricko in Piran :). In addition, with certain gases form acid rain, which has for some years with us destroy the vegetables in the garden.
B) Cleanliness roof: even if we have a smooth covering, we may wind layers of dirt, in addition crows often leave residues on the roofs of small rodents, which are not exactly desirable game kapal perang content game kapal perang in the rainwater tank.
These two can be relatively easily game kapal perang resolved by redirecting the first gradient (Briefings First Flush diverter). The idea is to get the first 10-15 minutes of rain passing the reservoir, and then, when the roof and the air is clean, the water diverted into the container. In Slovenia, we are here with one to 50 years for the wooden spoon and anywhere I could not get'' first flush'' diverterjev. Basically, you can do this in two ways.
The first inlet tube mounted on the tee. On the arm, which leads down to mount the barrel (size depends on the size of the roof), which has in itself the ball. Initial dirty content comes after the inlet hose and into the barrel when the barrel is filled, it is closed at the top of the flow, and thus the remaining (now pure) shifted forward in the rainwater reservoir. The problem with this type is that it has to be manually emptied barrel after each rain and the inability of detecting rainfall (with gentle rain barrel before it becomes full before the roof really washed out). The first overflow tank. Source: http://rainharvesting.com.au/
Both are good save another system - the'' first flush valve''. VT-piece is a ball which has a hole at the top. Only when the flow is strong enough (really rinsed atmosphere and roof), the ball begins to charge the water and close the leak, the rest of the rainwater is diverted into the reservoir. In Australia is that such a system to get 100 + postage (in theory ... but when you pay VAT and customs duty, the final amount slightly less than 200 ). The first dressing the valve.

Before game kapal perang going on rainwater overflow valve first we need to remove coarse debris-leaves, dead animals ... , Which is best achieved with the mesh stretched over the grooves, or later with the mesh in the drain pipe, preferably so that the mesh placed horizontally, water is the free-fall flows through it. If the first overflow its done in the hopper send only clean water (which can directly or even through additional filters (sand, carbon ...)). Given filtering systems on Slovenian game kapal perang and foreign websites game kapal perang is that some instructions how to do it. Carbon filters on my
