Is it safe to drink or what?
- 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.
These two sentences seem to contradict each other. Why is a sign needed if it's so safe - usually safer, the previous text claims, than fresh water from the tap? Tempshill 03:00, 17 March 2006 (UTC)
ITS DEFINITELY NOT. I personally changed this article because i could not beleive that someone actually wrote that it was CLEANER than drinking water becasue it has removed some of the moinerals present in drinking water. You can actually smel the sewage in reclaimed water when people use it in sprinklers and other things. There are nearly 30 different chemicals present in it including hormones like birth control and pharmaceuticals and other things that the long-term effects on the human body are unknown. No one should EVER drink reclaimed water. [This unsigned comment was made by User 220.127.116.11]
- Please do your research and cite your sources when making those types of changes to an article (changing "reclaimed water is often cleaner than standard drinking water" to "reclaimed water is unsanitary"). I edited the article to make note of the fact that some pharmaceutical chemicals pass through the filtering process, but it is easy to find at multiple sources that reclaimed water is usually treated to higher standards than ordinary drinking water in order to ease people's concerns about it being unsanitary. --taestell 01:21, 18 May 2006 (UTC)
Reclaimed water can be made clean to any arbitrary level required. In NSW, Australia, reclaimed water is indeed made cleaner than ordinary "tap water". There are political/psychological reasons it is not actually used for drinking, but it is completely potable. Ordinary Person 00:17, 11 December 2006 (UTC)
However, the U.S. has found similar tests unreliable.
You can't just say 'the US' without refering to a specific organisation. Additionally, editing this sentence in where you have gives the casual reader the impression that the pre-existing reference which now follows the new sentence contains information supporting the new information, which is most certainly does not (at no stage during the transcript is any U.S. organisation mentioned).

Reclaimed water and potable water
The current text includes this line:
Reclaimed water is not directly mixed with potable (drinking) water for several reasons:
This seems a very broad statement. Currently reclaimed water is turned into potable water in various places, by feeding the reclaimed water back into the dams that provide water that is made potable and distributed as tap water.
That is to say, "reclaimed water" and "potable water" are two intersecting sets, not mutually exclusive categories. Ordinary Person 00:16, 11 December 2006 (UTC)
Recycled Water is the Future
The ignorant barrier some people have created upon themselves is unbeleiveable. Do your research... recycled water is perfectly fine to wash, bath-in or drink. It is water treated after the secondary treatment and through the processes of Microfiltration and Reverse Osmosis. And.....yes by this stage it is perfectly fine to drink. No you will not get diseased, sick, or someway deformed. All you will get is pure drinking water. I believe you are deeply inconsiderate if your are against recycled water. Grow up....learn the facts....its not sewage. Plus other alternatives such as dessalinisation, just arn't a viable long-term solution (high costs and high usage of electricity). Ignorance can be overcome quite easily......so do just that.
No one knows what pollutants or mircrobes remain in reclaimed effluent. Leading experts who are not in the employ of the huge wastewater industry warn of risks to public health. Do your research.Notindustry (talk) 23:13, 12 May 2008 (UTC)
"often as clean as (or cleaner than) standard drinking water"
The reference provided lists a number of properties of reclaimed water but does not compare to standard drinking water. And the properties listed are not all the possible measures of how "clean" the water is. -- Barrylb 04:31, 1 August 2006 (UTC)
Reclaimed water used for irrigation does not have reverse osmosis or microfiltation. According to USDA, "Using present technologies, municipal wastewater may not completely disinfect recycled irrigation waters,and can contain enough pathogenic organisms to threaten human health once released into the environment" US Dept of Agriculture, 2005 report. —Preceding unsigned comment added by Notindustry (talk • contribs) 15:51, 30 April 2008 (UTC)
Recycled or reclaimed
Google has more hits for "recycled water" than "reclaimed water". Currently recycled water redirects to reclaimed water. Perhaps it should be the other way around. -- Barrylb 12:42, 1 August 2006 (UTC)
Reclaimed irrigation water does not use reverse osmosis or mircrofiltration. According to USDA "Using present technologies, municipal wastewater treatment may not completely disinfect recycled irrigation waters,...Recycled water used for agricultural and municipal irrigation can contain enough pathogenic organisms to threaten human health once released to the environment." The same report says that organic chemicals in reclaimed pose an unknown risk to the environment. US Dept of Agriculture, 2005 annual report.Notindustry (talk) 16:06, 30 April 2008 (UTC)
As a Matter of Fact
Payson, Arizona lies at an altitude of about 5,000-Ft at the foot of the Mogollon Rim. It is arid (20-24 inches rainfall average) but not a desert : Ponderosa Pine country. Of course, the area is subject to drouths, some severe. It is a growing community under conditions of very little private land : Residential prices are skyrocketing.
As a component in a larger program program dealing with water problems, the town takes a part of the "almost potable" effluent water from the local sewage treatment plant and feeds it into the Town Lakes. There, the water percolates from the bottom of the lakes into the local aquifer below, where it is considered "fully potable" == and tests that way. It is estimated that an amount of water is recovered in this way to account for about 30% of the water needs of the Town in the winter. A higher proportion of the Twon's requirements will likely be possible in the future as the Town will no longer sell effluent for private purposes -- and as the rules regarding irrigation are tightened.
What IS hard to understand is why the Valley (Metropolitan Phoenix) does not have any similar WATER REUSE policies in place. Inquiries are ignored.

Turns out that the QLD Government is calling the Referndum a Plebiscite instead, since the word Referendum is specifically mention in the Constitution re changing governence. In reality, there is next to no difference, as the Plebiscite is still non-binding. Draffa 19:11, 27 January 2007 (UTC)
Clive Berghoffer's Objections
Quote from one of the currently-linked ABC Online articles:
Many local councils have supported Mr Beattie's decision, but former Toowoomba mayor Clive Berghofer says the food export industry is now in danger.
For any Aussies reading, Clive has substantial interests in land slated for development in Toowoomba. He was outspoken in the Toowoomba Plebescite on RW last year. One might suspect he wasn't concerned over the quality of the water, but rather the potential impact on property prices for newly-developed land. His statement over the now-cancelled South-east Queensland Plebescite seem to indicate his position still stands. Similar objections were raised several years ago by a Mayoral Candidate when Caboolture considered implementing Recycled Water some years ago during another severe drought (best summarised as "They want you to drink poo!").
Not that the water really matters to Clive, since the ABC's Quantum program has shown his 'house-sized' water tank under his suburban house. :D Draffa 17:37, 30 January 2007 (UTC)
"Humans may face psychological barriers against drinking reclaimed water, since it was formerly sewage".
Do the folks who have psychological problems with drinking reclaimed water ever consider the places where their breathing air has recently been -- say, through the nearest sewer or autopsy facility -- and that without any subsequent treatment ?
"Fresh air" contains a wonderful variety of the worst kind of filth and noxious substances -- but fortunately our bodies filter or reject most of it.
A touch of rationality does wonders. Allenwoll 00:29, 6 March 2007 (UTC)
I find it amusing that it has been considered a great step forward in sanitation to pipe sewage away from areas of human population. Now it is considered progess to give sewer water minimal treatment and to irrigate our lawns with it. It has been notoriously difficut to clean this water, especially of those fragments of pathogens which confer drug resistance on other microbes. Before giving it higher treatment and using it for drinking, many more studies, such as those using live fish, are needed. —Preceding unsigned comment added by Notindustry (talk • contribs) 19:03, 30 April 2008 (UTC)
plant in orange county...
70,000,000 gallons a day water reclaimation plant- purifies water coming from homes and will put it back in with the water supply for people rather than discharge it uncleaned into the ocean. - in orange county.. heard on news. may already be in article. smaller version of same plant already in singapore --Emesee (talk) 02:48, 21 January 2008 (UTC)
- Thermal depolymerization#Similar processes seems to mention the plant you are talking about:
- Sforza, Teri (2007-03-14). "New plan replaces sewage sludge fiasco". Orange county register. Retrieved 2008-01-27.
- The plant appears to be in Rialto, California, which is actually in San Bernadino County, California rather than in neighboring Orange County, California, but the plant will accept wastewater from Orange County. Interestingly, a byproduct of the plant will be carbonized sludge, or "E-fuel", suitable for burning in cement kilns as a substitute for coal. --Teratornis (talk) 16:11, 30 April 2008 (UTC)
- Actually on re-reading the article, I see the plant in Rialto is actually a sludge treatment plant, which will accept sludge from several neighboring water treatment districts, including Orange County. The water treatment plant you mention appears to have the name Groundwater Replenishment System:

I find it amusing that it was considered a great step forward in sanitation to pipe sewer water away from areas of human population. Now we are giving it minimal (secondary) treatment, and watering our lawns with it!
pathogens and endocrine disrupting chemicals in reclaimed
reclaimed water used for irrigation of lawns, golf courses etc. rarely receives tertiary treatment and does not get reverse osmosis or microfiltration. In its 2005 annual report, the USDA recognizes that endocrine disrupting chemicals and pathogens, including drug resistant bacteria cannot be removed with present technology, and can pose an environmental and human health threat.Notindustry (talk) 18:12, 30 April 2008 (UTC)
Using recycled water in space
Thought this might be worth adding to the article but I don't have time to do it at the moment: http://www.space.com/missionlaunches/090520-space-urine.html Robogymnast (talk) 18:06, 22 May 2009 (UTC)
" Reclaimed water planned for use in recharging aquifers or augmenting surface water receives adequate and reliable treatment..." Yes? This may or may not be true.--Wetman (talk) 15:10, 12 December 2011 (UTC)
Add information on National Research Council report
Hi, I'd like to add some text about a January 2012 National Research Council report about water reuse. You can read more about the report here: http://dels.nas.edu/Report/Water-Reuse-Potential-Expanding/13303
This is the text I'd like to add:
- In a January 2012 National Research Council report, a committee of independent experts found that expanding the reuse of municipal wastewater for irrigation, industrial uses, and drinking water augmentation could significantly increase the United States’ total available water resources. The committee noted that a portfolio of treatment options is available to mitigate water quality issues in reclaimed water. The report also includes a risk analysis that suggests the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water is not any higher than the risk from drinking water from current water treatment systems—and in some cases, may be orders of magnitude lower. The report concludes that adjustments to the federal regulatory framework could enhance public health protection and increase public confidence in water reuse.
