Talk:Waste stabilization pond

message: Hi. I made several dozen standard copyedit changes. As a professional editor, I thought it might be worthwhile to explain to the folks working on this article what most of the changes were:
* Misspellings were corrected. In particular, there were several situations where two words were merged into a compound word that does not exist in American or British English.
* Incorrect grammar was corrected.
* Redundant words such as "also", "finally" and "zone" were removed.
* Elipses (dots) were removed. None were needed in this article.
There were some situations where I wasn't sure of the meaning, and I left those unchanged, even if they did not look correct.
Of the many aspects of this article which might be expanded in an interesting way, I find the use of fish in this process surprising.

thread_title: Copyedit changes

message: After thinking about the topic and the article, I started coming up with questions. Again here it is . 
* What are the range of costs to build? How much for upkeep? Are we talking hundreds or millions, here?
::Costs can vary from individual time and effort similar to residential landscaping for a small pond to significant capital investment and routine maintenance expenses for industrial or municipal wastewater treatment.  All ponds require maintenance, and the frequency of maintenance depends upon the quantity of waste received.  Most ponds convert waste to biomass which must be periodically removed.  Settling biomass will otherwise decrease pond depth and floating biomass scum functionally stops treatment by shading ultraviolet light and preventing gas transfer at the pond surface.  Biomass is typically removed from the pond as a wet sludge which is difficult to handle and may become offensively anaerobic in the drying process.
* Are these ponds built by professionals, or just using commercial supplies?
::Professional advice generally provides better spillway and seepage control, and may be important in determining required pond surface area and detention time for effective waste treatment.
* What are the alternatives? I can understand that sewage cannot be dumped in urban areas, but why not in farming country? Aren't these animal byproducts fertilizer?
::Animal waste has similarly offensive odors, pathogen concerns, and watercourse eutrophication potential of human sewage. 
* Is any part of construction and use subject to building codes or official review?
::Potentially yes, depending upon local codes.
* What, exactly, does the "cleaning"? Plants? Bacteria? Fish?
::Ultraviolet radiation from the sun may kill undesirable micro-organisms if the pond water is clear, but will be less effective if the pond is turbid or shaded by nearby structures or aquatic vegetation.  Gas transfer at the pond surface is also important.  Oxygen from the atmosphere will enable some micro-organisms to chemically convert organic material to carbon dioxide or to growth of plants and animals living in the pond.  Undesirable gasses like ammonia and hydrogen sulfide may be released from the water to the atmosphere (good for water quality, but may cause odor problems).  Evaporation increases concentrations of salts, metals, and some other chemicals.  Some of these chemicals may precipitate or sorb to the biomass accumulating in the pond, but the remainder will leave with pond overflow. 
* Is it correct that the purpose is to only to remove anaerobic bacteria?
* What value do the treatment ponds have, when used in conjunction with septic tanks in urban areas?
* Why is it necessary to have three "levels" of fish? For four "zones"? Aren't there fish that swim to all depths?
* What does a "complete ecosystem" mean? Isn't the idea for the ponds to act as a part of a larger ecosystem?
* The reference for "Water Works" leads to an interesting page. The stated goals there are to create "green water" (a concept that is not covered in Wiki, btw, but might well be). Is creating "green water" always the goal of these ponds?
* In terms of avoiding advertising, it might be good to include a link that the Water Works site does, to an industry association:  www.greenroofs.org
* Particularly in regard to the roof versions, are these meant to be economical (as the other treatment ponds appear to intend), or is this intended partly as an "ecological proof of concept", rather like putting solar panels on roofs?
* And this is just one related to my personal situation: Are treatment ponds practical in areas where there's limited year-round water availability?
Why do you need to do this ?

replies: text: These are good questions.  The situation described in this article is firstly a pond.  Some things happening in a pond may be called treatment; but it is important to consider potentially undesirable consequences of ponds.  Most ponds provide mosquito breeding habitat; and people can drown in larger ponds.  Pond construction carries a liability risk of damage from unexpected release of water contained therein.  I have inserted brief answers within a few of your questions above.Thewellman (talk) 21:11, 1 June 2012 (UTC)

message: Besides purifying the water, energy production is perhaps also possible with reed bed systems; perhaps include image on the right ?

message: I am really interested in whether or not these systems could solve both water scarcity and water contamination problems in the Third world. For instance water in India is highly contaminated with both fecal bacteria and Arsenic. Can plants be used to solve these problems? Paul Layne (talk) 00:12, 22 September 2011 (UTC)

message: I have just done a clean-up of this page as it was mixing up information of reed beds (constructed wetlands) with treatment ponds. I further propose to take the content and merge it into the page on stabilization pond which is a much better page already and deals with the same subject. We could then have a re-direct from treatment pond to stabilization pond. EvM-Susana (talk) 10:11, 24 April 2015 (UTC)
thread_title:  Merge with article on stabilization pond 

message: User:SoCalYooper: did you take a look at the hatnote before you started to edit this article? It said:
"This article is about ponds similar to surface flow constructed wetlands. For wastewater treatment ponds, see stabilization pond." You have now made it into another article on stabilization ponds. Rather you should have edited the article on stabilization pond. You probably would have found that a lot of your information is already on there. Now we have a messy situation where two articles describe the same thing. This needs to be resolved.  EvMsmile (talk) 11:26, 22 April 2016 (UTC)

message: As per the discussion above, I have created a new article called waste stabilization pond from the draft that was in the sandbox of User:Thewellman. What are now the next steps? And has all the relevant content from treatment pond been included in the new article - e.g. what about the section on sizing? Once everything is included and merged then stabilisation pond needs to be redirected to waste stabilization pond.EMsmile (talk) 13:33, 23 October 2017 (UTC)
replies: text: OK, so I have placed a redirect from stabilization pond to waste stabilization pond. This page here now needs to be converted into a disambiguation page, right? As stated above "convert the treatment pond article to a disambiguation page listing the broader range of pond articles describing differing design features intended to improve water quality." Can you do so, User:Thewellman?   EMsmile (talk) 08:14, 26 October 2017 (UTC)
replies: text:  I suggest the first step would be to replace this article with a redirect, indicating the merged article contains the essential elements of this article. I would prefer to delay that replacement until consensus is received from two major editors KVDP and SoCalYooper that the merged article meets their satisfaction. Once the article is replaced by a redirect following this procedure, I am prepared to replace that redirect with a disambiguation page. Thewellman (talk) 03:26, 27 October 2017 (UTC)
replies: text:  I think anyone watching this article has had ample opportunity to respond by now and you have even pinged the two major editors twice. If they don't react then it means they are either fine with it or don't care. This editor: SoCalYooper was by the way a student editor and hasn't been back since 2016. So I will now place the redirect and try to put the history merge in motion. EMsmile (talk) 09:33, 27 October 2017 (UTC)

thread_title: Merger completed - new article set up

message: I've been in touch with an expert on waste stabilization ponds from Brazil. He's sent me a marked up Word document of this Wikipedia article. I plan to add his changes slowly into this article over the coming week or two. I think they will be good improvements but if anyone has any concerns, please put them here, now or later as I go along. EMsmile (talk) 00:33, 6 January 2018 (UTC)
replies: text: Thanks, User:PlanetCare for adding those edits of Marcos to the Wikipedia article, much appreciated! I will now work on the new references. EMsmile (talk) 00:18, 19 January 2018 (UTC)
