Hi !!!\n\n"Water harvesting is simply collecting rainwater that falls on your property and then putting it to use around your home or yard-- that's all there is to it!\n\nMany Pima County homeowners use rainwater to irrigate trees, lawns and other landscaping. You can substantially lower your water bill, help reduce local flooding and reduce landscaping and property maintenance needs--- all by putting water harvesting ideas to use around your home. Whether you're building a new home on an single lot, designing a major subdivision, or just making a few improvements around your yard, water harvesting can be easily incorporated into your plans." >http://rfcd.pima.gov/wh/\n\nThough the above article refers to a certain place, it is for every one and please remove the word and understand the data.  Please go through the website for lot of details.  \n\nUseful links:\n\nhttp://www.aboutrainwaterharvesting.com\nhttp://rfcd.pima.gov/wh/\nhttp://www.sustainable.com.au/rainwater.html\nhttp://www.rainwaterharvesting.org/\nhttp://rfcd.pima.gov/wh/\n\n\nI hope this helps.\n\n\n>>> Naveen Kumar

Purifying water is far more expensive than that... You should get rid of organic compounds (floating and in solution), kill microbiological creatures... And assure that it won't be harmful for your health after all that, besides taking care of pH, smell, etc.

There are many different ways to make questionable water drinkable.\n\nBoiling- Bring it to a rolling boil (might want to leave it for 2 minutes just to be sure)\n\nChemical treatment- Outdoor stores carry products, follow package instructions\n\nFiltration- Water filters don't usually filter out virus' so chemical treatment is usually still needed\n\nUV light treatment- Special Lights are now on the market that can treat water in short time (See: http://www.bentgear.com/product_info.php?cPath=21_53_54&products_id=385)\n\nThere are other but not as common methods such as a machine that can produce chemicals that kill bacteria. \nHope I helped!

Reclaimed water \nReclaimed water is wastewater (sewage) that has been highly treated and purified, and is as clean as (or more commonly, cleaner than) standard drinking water. Reclaimed water is frequently used to irrigate golf courses and parks, fill decorative fountains, and fight fires. It can also be used to irrigate crops, as long as they will be peeled or boiled before human consumption.\n\nUsing reclaimed water has many benefits. It conserves drinking water, is less expensive, and contains higher levels of nitrogen and phosphorus, which help fertilize plants.\n\nThe costs involved with recycled water typically exceed those of standard potable water in most regions of the world, where a fresh water supply is plentiful. However, in areas where supplies of fresh water are limited, treating wastewater for reuse in certain applications is becoming an economically attractive option. This is why many cities in Southwestern United States make use of reclaimed water.\n\nReclaimed water is not directly mixed with potable (drinking) water, even though it is usually cleaner than drinking water. This is because the extra filtering processes may remove minerals that are present in standard drinking water, and also because humans may face psychological barriers against drinking reclaimed water. Many cities actually ban citizens from drinking, bathing in, or filling swimming pools with reclaimed water, although the risk of harmful effects associated with doing so are very low. If you irrigate your lawn or plants with reclaimed water, you should place a sign on your property warning people not to drink from the irrigation system.\n\nOn the other hand, many cities are now investigating indirect potable use of reclaimed water. For example, reclaimed water may be pumped into reservoirs where it will mix with (and be diluted by) rainwater. This mixture of rainwater and reclaimed water could then be treated again, and finally used as drinking water.\n\nMany large cities using water from rivers are inevitably using water that came from treated sewage discharged upstream. London water had a reputation of having been drunk five times before it arrived at the tap, but this is an exaggeration. There are many large towns on the River Thames upstream of London (Oxford, Reading, Swindon, Bracknell, etc.) whose sewage discharge is subsequently used to supply London with water. This phenomenon is also observed in the United States, where the Mississippi River serves both as the destination of sewage treatment plant effluent, and the source of potable water. Research in the 1960's (London Metropolitan Water Board) demonstrated that the maximum extent of re-cycling water is about 11 times before the taste of water induces nausea in sensitive individuals. This is caused by the build up of inorganic ions such as Cl-, SO4--, K+ and Na+ in the water. Such ions are not removed or reduced by conventional sewage treatment.\n\nReclaimed water is distributed with a dual piping network that keeps reclaimed water pipes completely separate from potable water pipes. In the United States, reclaimed water is always distributed in lavender (light purple) pipes to distinguish it from potable water.\n\nIn many cities using reclaimed water, it is now in such demand that consumers are only allowed to use it on assigned days. Some cities that previously offered unlimited reclaimed water at a flat rate are now beginning to charge citizens by the amount they use.\n\nIn Singapore, reclaimed water may be labeled NEWater.\n\nA less elaborate alternative to reclaimed water is a greywater system. Grey water is water that has been used in sinks, washing machines or showers, but does not contain sewage (blackwater). In a home system, untreated grey water may be used to flush toilets or for irrigation. In a city-wide system, grey water may flow in a set of pipes separate from other sewage to a treatment plant, where it can be treated and used in similar ways as reclaimed water.

Depends on how you set it up.\n\nThe result will range from a more complete oxidation of waste to ozone saturating water and start to leave water phase.\n\nOzone is a toxic gas, - avoid ozone release.\nTreated waste will qualitatively not be more harmful than for a "normal" ozone dosis. The quantities of ketones, aldehydes, acids and carbon dioxides will increase and harmfullness depends on quantity.

lol look at the first two answers!\n\nlet's assume you are asking about big aquariums.\nthey make their own.  the have giant RO/DI (reverse osmosis/deionization) filters. They just pull out the chemicals, heavy metals and dissolved organics. Then they put back in vital trace elements, like magnesium, strontium, (and calcium but thats not 'trace').\n\nsmall aquariums, like in your kitchen\nstart with regular tap water, but pull out the chlorine and chloramines as well as copper, lead, etc. you can do this by mixing in something called 'Prime' by seachem. This website will tell you everything you need to know. \n\nPS--he talks about Prime, but Prime's label doesnt say that it binds heavy metals. it does. i dont know why they didnt put it on there. we actually called Seachem and asked them. They sent us this giant analysis of their stuff.

basically you're talking about distilling water, which is a purification technique.  collect the water vapor and let it condense. the result is pure water.

i. Channel rainwater from your roof and maximise the storage of rainwater.\n2. Re-use grey-water (from showers, washing clothes) through a natural plant filter for use in irrrigation, washing, flushing toilets. \n3. Check your water system for any leaks\n4. Use a dry toilet (natural composting system)\n4. For more ideas, check out any Permaculture websites

This is what I would reccomend to install for "purified water" First a water softener followed by a commercial reverse osmosis unit...something scalable in case you need more capacity down the road. After the R.O. run it through an ultra-violet unit. this will kill any bacteria. At the bottling point, inject ozone with an ozinator to ensure that no bacterial growth will occor in the bottle. As long as the bottle is sealed, it is good for a couple years.

Almost all countries have this problem ; some big , some small.\nIn many cities in Asia the sewage water disposal system is very badly managed. They are not treated effectively before it is allowed to be discharged into rivers or seas. Some do not have the treatment plant and in some the plants are not maintained propery.\nNear the butcheries where the hides and skins are washed and proceesed , in sugar industries the molasses, in dyeing industries the wastages etc etc are polluting the ground water resources.Earlier the film industry used to pollute the ground water ,.\nMany chemical industries the toxiv wastes pollute the water sources.\nI remember my child hood days when we used to drink the free flowing river waters with our hands. No more now.

To keep our used water from spoiling our water resources, we have to remove the pollutants before the water gets back into the environment. In urban areas in most developed countries, the wastewater from homes, businesses and factories is collected by a system of underground pipes-- sewers-- which carry it to one or more central treatment facilites. Most of these are located near bodies of water into which the treated wastewater is discharged. \n\nIn the U.S., all such facilites must have a permit issued by the federal and/or state government, describing limits on the amounts of various pollutants which may be discharged. The U.S. EPA (Environmental Protection Agency) refers to these as NPDES (National Pollutant Discharge Elimination System) permits. Industries located in areas where they are not connected to a sewer can discharge directly into a waterway, but will need a permit, and will probably have to have their own treatment plants. Even industries which are connected to sewers may have to pretreat their wastewaters before discharging them into the sewers, because they may contain materials which will harm the sewers or the treatment plants-- or may be a danger to the people who work in maintaining the sewer system.\n[If you are some one who works in an industrial pretreatment program, you may be aware that the USEPA has recently (July 22, 1999) proposed a series of changes to the current regulations. I have prepared a summary of the proposals which you may find helpful before reading the entire document.] \n\nHomes in non-urban areas that are not connected to a sewer are usually required by their town to have on-site treatment systems. Most common for single homes are septic systems, which consist of a buried tank connected to a set of perforated pipes, embedded in gravel, which distribute the water into the soil. (The "Links" page has several references on this subject.) Larger housing complexes may have treatment systems based on the principles used in full-scale sewage treatment plants. \n\n\nA Word About Sewers: Besides having a set of sewer pipes-- called, strangely enough, sanitary sewers-- which carry wastewater to a treatment plant, cities and towns also need pipes to collect stormwater. These are needed to prevent street flooding and usually lead directly to a waterway without any treatment. The runoff of pollutants from streets and yards into these storm sewers contain oil and other automotive wastes, which may contain toxic metals and organic compounds-- as well as pesticides and nutrient-containing fertilizers from lawns and gardens, and pathogenic microorganisms from animal wastes. The problem of pollution from storm sewers is currently being addressed by the USEPA. Further complicating the situation is the fact that while some cities and towns have completely separate sanitary and storm sewer systems, many others have combined systems. During rainy periods, combined sewers cause two problems: overloading of the treatment plant with extra water and contaminating waterways with untreated sewage from overflows. Even in cities with separate sewer systems, the flows to the treatment plants often increase greatly when it rains because of cracks or separations in the pipes, which allow groundwater or stormwater from broken storm sewer pipes to infiltrate into the sanitary sewer-- or from direct inflow of stormwater into manholes and from illegal connections of roof drains and sump pumps in buildings.*

From How Stuff Works:\n\n"Reverse osmosis (RO) is used to reduce dissolved solids from feed waters with salinities up to 45,000 ppm TDS (total dissolved solids). Municipalities and industrial facilities are able to use RO permeate as a consistently pure drinking water supply and to transform drinking water to high purity water for industrial use at microelectronics, food and beverage, power, and pharmaceutical facilities. The technology is also very effective at removing bacteria, pyrogens, and organic contaminants."\n\nSo, I would think that it would be pretty good for you -- on the other hand, every brand of it that I have tried -- has given me digestive problems!! Go figure. I use just regular spring water or a filtered water from Brita or some such, myself.

That is why I only trust on tap water from home with a system that would remove most or allchemicals and metals in the water. Others have bacteria and metals that make you become poisoned, damage your nerves or make you ill.
