I just found this forum while searching in Costa Rican water and wastewater issues and would like to add some my own personal history and philosophies.

I believe that a good business foundation needs a logical and proven sustainable technology in order to even begin to create a successful model.

For over 45 years I have developed a decentralized blackwater (composting) large treatment tank and a grey water aerobic treatment system and a grey water filtration, ozone disinfection and reverse osmosis recycling system capable of recovering 95% of the grey water into potable drinking quality water without the yuck factor. Utilizing ultra-ultra low flushing toilets and recycling the grey water has reduced the need for water by 97% and wastewater pollution to the environment by 100%.

Entire systems are installed in a buried or above ground 8' x 8' x 20' container next to the residence or business and monitored via the internet.

Rates of usage are calculated upon total amount of water utilized, treated and recycled. Financing with home improvement loans based upon a maintenance and monitoring contract.

With the monitoring via the internet all security and any other business services can be provided and will expand the market base based upon WATER.

Thank you,

I am glad your are happy about this. Note that we have long had this sub-category here:
forum.susana.org/forum/categories/40-gre...rigation-aquaculture

which is where topics about wastewater reuse and irrigation can be discussed (although admittedly purely irrigation topics with e.g. groundwater and with no links to wastwater were not usually part of this sub-category - but at the end of the day the whole water cycle is all connected, isn't it).

Note we also have a big thread on wastewater irrigation and nutrition here:
forum.susana.org/forum/categories/92-nut...iene-and-agriculture

It's called: "WATSAN-AGRICULTURE: Improving on the Nexus among Water Quality and Quantity, Sanitation, Hygiene, and Agriculture"

I would have put it here in this category, but the person who started the thread said she'd rather have it in the other thread to emphasis the link with health and nutrition.
You might find it interesting if you haven't seen it yet.

Toilet-to-Tap Water Project of India (wastewater treatment and reuse) - by: F H Mughal http://forum.susana.org/forum/categories/40-greywater-blackwater-or-wastewater-reuse-irrigation-aquaculture/14312-toilet-to-tap-water-project-of-india-wastewater-treatment-and-reuse#14312 http://forum.susana.org/forum/categories/40-greywater-blackwater-or-wastewater-reuse-irrigation-aquaculture/14312-toilet-to-tap-water-project-of-india-wastewater-treatment-and-reuse#14312 Toilet-to-Tap Water Project of India

India has developed a project that converts sewage to treated drinkable water.

www.takepart.com/article/2015/07/20/toilet-to-tap-water-india


www.hindustantimes.com/newdelhi/delhi-s-...rticle1-1367659.aspx

In the post, Sanchaita Gajapati Raju, founder and managing trustee of SANA, is pictured as she drinks the treated water at Keshopur Sewage Treatment Plant in Delhi. The Delhi chief minister Arvind Kejriwal is also pictured tasting the treated water. I tried to copy-paste the 2 photos here, but it did not work - may be the moderators can help

Note by moderators: here you are (I used the image link button above and truncated the URL so that it stops after ".jpg"):





Treated water from sewage is not uncommon. In fact, this happens all the time. For example, Indus River in Pakistan receives untreated wastewater discharges in its upstream reaches. The river then becomes the raw water source of the towns in downstream reaches.

I think, it is far better, if the polluted waters, both, the surface water and the ground water, are treated and made drinkable. In many towns in Sindh province of Pakistan, people get water for drinking that is not quite wholesome.

Different urban scenarios for Wastewater Treatment and Recycling - NaWaTech project in Pune and Nagpur, India - by: saurabhkale http://forum.susana.org/forum/categories/40-greywater-blackwater-or-wastewater-reuse-irrigation-aquaculture/14303-different-urban-scenarios-for-wastewater-treatment-and-recycling-nawatech-project-in-pune-and-nagpur-india#14303 http://forum.susana.org/forum/categories/40-greywater-blackwater-or-wastewater-reuse-irrigation-aquaculture/14303-different-urban-scenarios-for-wastewater-treatment-and-recycling-nawatech-project-in-pune-and-nagpur-india#14303
The NaWaTech project is a joint implementation and research project between India and EU and is funded by the Department of Science and Technology (Government of India) and the European Commission. The idea is to assess and enhance the potentials of natural and technical water treatment systems to suit to the local hydro-geological conditions. The systems will also be able to treat variable flows of wastewater in order to reuse it and to supplement traditional sources to cope with urban water shortages today and in the future.

The project implementation will take place in the cities of Pune and Nagpur. This paper aims to focus on the site implementation in Pune. These sites are: College of Engineering, Pune; Maharashtra Jeevan Pradhikaran Office; Amanora Park Town; Indradhanushya Environment and Citizenship Centre.]]>

When Raul says the concept needs to be "extended beyond agriculture" what does he mean exactly? Also, the article compares the amount of water used for irrigation and the "drinking water" requirements. But is the term drinking water really meant as water for drinking or any type of water used in urban spaces?

I ask this because the amount of water we actually drink is so small (2-3 L per person per day) compared to our other water uses in the urban space, more like 60-200 L per day, depending on your country and wealth and life style... (for personal hygiene, toilet flushing, gardens, parks, industries, ...), and it could also potentially come from different sources; therefore, there may not really be an issue with running out of "drinking water" from too much irrigation in agriculture, is there?


I think the point that Raul is making is that the report talks about governments not prioritising water for food security and nutrition when in fact many governments do prioritise the water for irrigation purposes. He then says that marginalised urban people are not prioritised in terms of water supply because food and water security is always talked about in terms of irrigation rather than in terms of potable water, so urban people end up at the bottom of the priority list.

So given that the SDGs are trying to focus on several aspects a the same time - and as we know the SDG water goals/targets are much more comprehensive than the MDGs which only focused on WASH - then the danger is that the priority will be irrigation rather than potable water delivery.

I don't know if specifically he is talking about the volume or quality of drinking waters available, but as a geographer, I think he is probably talking about the general potential conflicts between water uses in places where there is a limited amount of non-saline water. Of course, everywhere is different, but he is talking from a perspective in Mexico.

This reminds me of a point that Kris made: he basically said, a slightly contaminated household well might not really be a serious problem, provided the households use it for all other uses but not for drinking water (18 July):
forum.susana.org/forum/categories/193-gr...2&start=12#14233

He said:
A well that is only lightly contaminated, but the water is actually used for personal hygiene and other domestic purposes, while the drinking water is bought from a more safer source or treated in the household (as quite common here), is in my opinion preferable to one that uncontaminated but rarely used.


So I am just wondering if the term "drinking water" is meant to be understood literally here or rather as "water used for activities by people in urban centres"?


I can ask Raul about this specific point, he is a very approachable guy. I think again he is talking about the risks of people in urban areas losing out as a result of pressures on water supplies due to government political priorities. I know he also believes that there is a lot of scope for wastewaters being reused in agricultural irrigation, so maybe he think that there is a danger if there is a lack of "joined-up thinking" rather than that it is a problem which is impossible to resolve.

Edit: Actually it could also be an English language issue here, as drinking water equates to potable water or " water safe enough for drinking and food preparation" (en.wikipedia.org/wiki/Drinking_water) - still the issue remains with the different quality levels of the water required, i.e. you can use different water quality for irrigation than for use around the home.


Yes, I'm sure that is also true. Again, I think Raul is pointing out (with a big brush) the possibilities of a danger of prioritising "food and water security" without also thinking about how urban poor people are going to get their drinking water.]]>

I didn't fully understand this part of your article, Joe:

However, conflict between using water for agriculture or for drinking would remain, according to Raul Pacheco-Vega, a geographer at the Centre for Economic Research and Education in Mexico.

He says that the concept of water for food security and nutrition needs to be extended beyond agriculture, as the existing focus on farming could leave urban communities without enough.


And the catchy title was: "Don’t put irrigation above drinking water"

When Raul says the concept needs to be "extended beyond agriculture" what does he mean exactly? Also, the article compares the amount of water used for irrigation and the "drinking water" requirements. But is the term drinking water really meant as water for drinking or any type of water used in urban spaces?

Nightsoil is commonly used in Bangkok. I learnt it from there.

"Cloak Room" is used for toilet in some commercial buildings in Karachi

It seems like a very interesting publication. Interesting that those WHO reuse guidelines from 2006 are still valid and don't need a revamp, but only a "translation" into practice, which is what this document does, I believe.
Interesting also the comparisons with water safety plans.

And yes, Mughal, I liked their abbreviations page and used it to update our common abbreviations page immediately:
en.wikipedia.org/wiki/List_of_abbreviations_used_in_sanitation

When it comes to their glossary, I was surprised to see the term "nightsoil" used in their glossary: "Untreated excreta transported without water (e.g.
via containers or buckets)."

To me, this seems like a historical term which is rather ill defined (although interestingly it implies the fertiliser aspect in it). Mind you, it only appears in their glossary and nowhere else in the document anyhow.]]>

This report emphases that safe drinking water and sanitation are fundamental to human development and well being. Yet inadequate access to clean water undermines people’s nutrition and health through water-borne diseases and chronic intestinal infections.”

The importance and value of safe reuse from wastewater for Global Food Security is also emphasized in this report. In other words a very important state of the art document from the Global Food Security community incorporating the importance of Sanitation and reuse. A good read ! Enjoy !

The World Health Organization (WHO) has issued a new publication - Sanitation Safety Planning: Manual for Safe Use and Disposal of Wastewater, Greywater and Excreta – that aims to protect the public health.

According to WHO, the publication will assist the users to:

• Systematically identify and manage health risk along the sanitation chain;

• Guide investment based on actual risks, to promote health benefits and minimize adverse health impacts; and

• Provide assurance to authorities and the public on the safety of sanitation-related products and services.

As if to increase its scope, Maria Niera, Director Department of Public Heath, Environmental and Social Determinants of Health, WHO, in her foreword, says:

“Sanitation Safety Planning is a tool to help sanitation system operators maximise health benefits and minimise health risk of their system. It guides operators to prioritize and target risk management efforts to where it will have the most impact and to improve over time. The outputs can be used to provide assurance to the public and authorities of the system performance based on sound risk based management.”

Interestingly, the Sanitation Safety Planning manual was tested with national authorities in Hanoi, Vietnam; Karnataka, India; Lima, Peru; Kampala Uganda; Benevente, Portugal; and Manila, Philippines under the guidance of a strategic advisory group and with review by experts and practitioners. This shows the publication’s global exposure.

The publication has a useful list of glossary and abbreviations, an aspect which Elisabeth will be delighted to see!

The companion volume of the publication: 2006 WHO Guidelines for Safe Use of Wastewater, Excreta and Greywater, is, I believe, available in the forum’s library.

The publication is available at: www.who.int/entity/water_sanitation_heal...er/ssp/en/index.html
