The world needs more toilets, but Western solutions aren't the answer

Today, 35.8% of the world’s population still lacks access to any proper sanitation facilities.

That’s why in 2015, the world’s leaders agreed to strive for access to adequate and equitable sanitation and hygiene for all by 2030 as part of the United Nations Sustainable Development Goals. That means more than three billion extra people will need access to a toilet.

But if we solve this problem with the flush toilets we’re used to in the West, we will have a whole new water access and sanitation problem on our hands. <...more...>

Israeli Solar Desalination Process Cuts Energy Costs by 90%

Israeli ​startup ​TSD (Tethys ​Solar ​Desalination)​ plans to ​revolutionize ​the process ​with a low-cost,​ off-grid, ​scalable, and ​environmentally ​friendly module ​technology ​using only the ​power of the ​sun. 

The most ​common method ​of reverse ​osmosis using ​membranes is ​costly, energy-​intensive, high-​maintenance, ​and environmentally ​problematic. It ​is best suited ​to mega-scale ​plants built on ​large tracts of ​high-value land ​near the ocean ​and consumes ​enormous ​amounts of ​electricity ​generated from ​fossil fuels. ​Then, the ​treated water ​has to be piped ​great distances ​to farms, ​industries, and ​households. ​ (more)

Humanity's Most Problematic Attempts to Get All the Water

Survival shows are running amok. The contestants are naked; they’re two out-of-shape guys in the woods; they’re stuck on an island. Despite differences in attire or setting, one thing remains constant: For every survivor, finding potable water is the first order of business.…  Read More

From Poop to Potable Water

This Ingenious Machine Turns Feces Into Drinking Water

I watched the piles of feces go up the conveyer belt and drop into a large bin. They made their way through the machine, getting boiled and treated. A few minutes later I took a long taste of the end result: a glass of delicious drinking water. (more)

Water 4.0

Water 4.0:  The Past, Present, and Future of the World’sMost Vital Resource is a new (2014) book by David Sedlak.   In it he details “(t)he little-known story of the systems that bring us our drinking water, how they were developed, the problems they are facing, and how they will be reinvented in the near future.”  Water 1.0 is what he calls the gravity-powered aqueducts engineered and built by the ancient Romans.  “…(T)he addition of filtration and chlorine disinfection on the front end of water distribution systems…” he refers to as Water 2.0.  “…(T)he installation of biological wastewater treatment on the sewer end…” is Water 3.0.  And, solutions to the challenges we now face will bring Water 3.x – Water 4.0 to our communities.  These solutions may be centralized, decentralized or some combination of both.  Sedlak does a good job of recounting the history and explaining the options we have as we move forward.  For anyone interested in an overview of the past, present and future of urban water, this book is well worth reading.

Oaxaca May update


It has been a much too busy week and a half here in Oaxaca. We arrived on Sunday night the 13th for what we hoped to be a full day of meetings with the head of the state water commission (CEA) and then a follow-up meeting with Sr Cajiga (the Finance Minister).  On the up-side ½ of the agenda happened.  We were not surprised as this is the way schedules and meetings go down here.  Typically, you have a meeting scheduled with someone or something perceived as more important comes up and the original meeting is canceled.  This happens all the time and you cannot take it personally (except that it shows you are lower on the priority list).

We came to Oaxaca specifically to meet with the head of CEA (Ruben), Adriana (from the finance minister’s office) and the Finance Minister Sr Cajiga. Our goal and purpose is to finalize and sign several contracts to help the state government analyze the health of many of their wastewater treatment systems and develop a framework and process for the Finance Minister’s office to follow when evaluating potential public works projects.  In the month prior to this trip we had been talking with Adriana who is the head of investment for the Finance Minister.  She helped us re-scope our proposals and arranged our meetings with the water commission and the finance minister.

Our flights were good and uneventful.  We left Seattle at about 7am on Sunday 13 May and arrived safe in Oaxaca by about 10:30pm.  Firdaus Jhabvala (Dr. J) had arrived about an hour earlier and was already checked into our regular hotel when we got there.  It was late but we stretched our legs with a walk to the Zocalo while strategizing about our next few days in Oaxaca.  Our first meeting was with Adriana at the INSO offices to formally meet her and prepare for the afternoon meeting with the state water commission.  Adriana informed us that we would NOT be meeting with Sr Cajiga because he was called out of town.  Thus, we knew the entire process would take much longer then she had planned.

Our first meeting with Sr Ruben (the head of the state water commission - CEA), went as we expected.  He was not receptive to our proposal, as it would take work away from him and potentially change the way he does business.  Dr J was GREAT as he called Ruben’s bluff and then Adriana jumped in and told him he needed to play by the Finance Minister’s ideas.  We left the meeting agreeing we would meet again on Wednesday to hopefully come to an agreement.  Adriana then treated us to a great lunch and we got a chance to socialize and talk some business.

We then got back to work modifying our proposal and budget to reflect the potential lack of support from CEA.  This included enlarging the scope of work and including time and budget to train and gather all the background data that CEA says does not exist!  We then met Adriana for breakfast on Wednesday morning.  We went to a great café that is a coffee co-op and helps coffee farmers improve their crop and value.  Adriana was very interested in the other work we are doing in Bravo Ahuja (rain harvesting) and our potential work with The Hunger Project.  After talking about these projects for awhile we got down to business.  I must first say we were the benefit of being more important. :)  Adriana initially said she had to leave by 9am to attend another meeting.  To our surprise she canceled it to stay with us.:)  We spoke about our new scope of work and the increased budget.  She was happy to hear our plan, and was not put off by the increase in the budget.  The rest of the day we cleaned up the proposals and we found a mistake in the budget spreadsheet we were working on close to midnight the night before!

We all gathered at 6pm at the CEA offices just outside of town to have our second meeting with Sr Ruben. This one went better than the first as we think he was told he has to go along with our plan as proposed by Sr Cajiga.  Still the meeting went for several hours until Sr Ruben agreed to our proposals.  We left with Adriana tasked with trying to find and secure a meeting with Sr Cajiga.  We knew this would take 3-5 days, but as it turns out it will be longer.

To help Adriana better understand exactly what we will provide, we took the CEA proposal and went line by line detailing the differences in our proposal and the CEA proposal.  The CEA proposal was basically a plan to raise and rebuild 99 treatment plants without understanding if they are repairable or the root cause of failure.  We have come to learn that CEA does not feel any responsibility for the failed plants and they are incentivized to build new ones vs fixing or developing a new process to ensure plants continue to work after they are built.  Adriana was very happy to receive these reports, as this will help her in talking with Sr Cajiga.

Dr J left to return to home to Houston on Thursday morning.  Adriana’s original idea about staying through midweek to finish up was much too optimistic.  Since our last meeting, we have been trying to put the proposals in their final form with the latest changes and in the format expected by CEA and the Finance offices.  We’re putting together our best guesses with the information that we have.  We are on hold with Adriana and Sr Cajiga waiting until he is available to meet with us.  Right now, we hope to meet with him on Tuesday 29 May, after we return from Mexico City (D.F.) from our meetings with The Hunger Project.


 Just because we have not yet met with Sr Cajiga does not mean we are sitting around partying!  We have been meeting with officials from Santo Domingo Barrio Bajo Etla (SDBBE), the filter company (working to install the filter system at the school at SDBBE), a representative from the Pura Vita coffee organization, The Oaxaca Hub, and Juan Jose (INSO) to plan how to manage the upcoming work with Sr Cajiga’s office and CEA.

Around town the city is at the beginning of the annual teachers’ strike which blocks most of the streets surrounding and including the Zocalo.  Nelly tells is this can go on for 3- 15 weeks!  First, it is TOTALLY PEACEFUL and it is sort of a huge street party.  Because there are teachers from all over the state, there are a lot of different craft vendors selling their wares.  Next, there is lots of GREAT street food on almost every corner.  The bummer is that the already bad traffic is even worse!

Our tickets to return to Seattle are for Wednesday 30 May.  At this point Stan will return as scheduled and Rick will stay another week or two in the hope of finalizing the contracts and securing the advance so we can start working on these important projects.

Stay tuned for more exciting news ( as we have time to write about it) :)

PLU Talk "Suffering from water in Oaxaca"

From the talk Rick gave at PLU late last month.

"We all need water, said Rick McKenney, executive director of Water for Humans.

McKenney kicked off the second day of the Wang Center’s Water Symposium with a talk about the challenges and opportunities with water and sanitation in Oaxaca.

“Suffering from water – this is what Mexicans say when they are dealing with a lack of water,” McKenney said. “Mexico considers water a public right but there’s a juxtaposition and some tension there. How do you equitably charge people for this asset?”

Upcoming Trip to Oaxaca Mexico

Upcoming Mexico Trip
Finally, after more than nine months, we have had a major breakthrough with the state government.

Water for Humans (WFH) will be traveling to Oaxaca to meet with Senor Cajiga, the Oaxaca State Finance Minister, on Oct 10th. The minister has agreed to meet with us (paying our travel) to discuss working on a strategy for water and sanitation, first for the central valley and hopefully for the entire state. This work will be divided between WFH and our partner NGO: Instituto de la Naturaleza y la Sociedad de Oaxaca INSO. WFH will be bringing Dr. Firdaus Jhabvala (from Natural Systems International/Biohabitats) to help with contracting and municipal sanitation.

Our goals for the finance minister are to do the following:
  • Secure a contract to develop a strategy for water and sanitation projects.
  • Secure commitments/funding for pilot projects.
We will be in Oaxaca for two weeks working with the Senor Cajiga and following up on our other projects: school water filer and rain catchment.

Saludos (Hi) from all of us at Water for Humans!

The families of Santo Domingo Barrio Bajo Etla and Victor Bravo Ahuja district of Oaxaca City have come to Water for Humans for assistance in securing clean safe water access.

Today, we are calling for your action to make a difference! boys at table

Imagine your child having to drink Coke in place of safe water.

That's what many Oaxacan families resort to.

The primary school in Santo Domingo Barrio Bajo Etla has foregone buying school supplies in favor of providing expensive bottled water for its students.

They've come to us to ask for help to install a water filtration system instead.

Meet the students of Santo Domingo Barrio Bajo Etla and Prof. Rosendo Barragan Mendoza

Mendoza Students-Outside Professor Rosendo Barragan Mendoza teaches grade 6 at Valentin Gomez Farias Elementary School located in the village. Prof. Mendoza said, "Sometimes when we run out of water jugs and children are still thirsty, they have to drink water from the tap and this causes many diseases." He tells us that clean filtered water would allow the school to stop buying expensive bottled water - and spend the money instead on school supplies.

How is Water for Humans helping the children, and the school?
In continuing collaboration with INSO, Water for Humans will install a water filtration-purification system on the elementary school's water tank.

Estimated Project Cost: $500

Water for Oaxaca - Rain Catchment Campaign

Logo-header

Saludos (Hi) from all of us at Water for Humans!

Imagine only getting municipal water once a week for 2 hours!

Imagine not flushing the toilet for 2 days because there is no water!

Water for Humans (WFH) is taking action to help alleviate the life-endangering effects of major water shortages in Oaxaca City, Mexico. We are responding to the cries for help from numerous families in the besieged Victor Bravo Ahuja district of Oaxaca City. They are asking Water for Humans and you to help them gain access to clean, safe drinking water. Here is a first-hand portrait of the human toll severe water shortages are exacting from the perspective of one family in Victor Bravo Ahuja!

Meet Susana Eva Vazquez
Suzanna is a community activist in the Victor Bravo Ahuja district of Oaxaca City. She wrote to Water for Humans and the Institute for Nature and Society in Oaxaca asking for our help in solving her neighborhood's chronic water shortages.

Vazquez This is what Susana told us: "Our neighborhood was a landfill and quarry before becoming a residential district. Originally, water service consisted of two spigots; over time, the delivery system was expanded. Now, due to population growth, it is extremely insufficient. Last year, during the dry season most residences received water only two times per week for few hours per day. The water ... is not potable."

With your support, here is how WFH wants to help Susana and her family...

Together with INSO, we are building 8,000 gallon rainwater catchment systems - a pilot project to be tested in eight homes in the neighborhood. The community members are committed to solving their water shortage problem by putting in almost $9,000, toward the total of $31,000!


Will You Answer Susana's Plea for Help?

You can help Susana and her family in this life-saving effort by helping Water for Humans today with a $25 donation via our CrowdRise site. Our financial goal is to collect $6,000 towards this cause. Your generous contribution will play a critical role in Water for Humans being able to implement this innovative, low-tech, sustainable solution. With your donation, Water for Humans will bring tangible and significant improvements to the lives of Susana and her family and so many others in Oaxaca City!

Droughts threaten nation’s food supply in Mexico

BY VÍCTOR MAYÉN
On Sunday, Institutional Revolutionary Party (PRI) deputies said that the country’s food supplies may be at risk. Nearly 500,000 hectares of crops of basic grains may fail due to droughts. 

In view of this situation, Manuel Humberto Cota Jiménez, the Secretary of the Agriculture and Livestock Committee, asked President Felipe Calderón to declare as disaster areas the states that have been affected by lack of rain. He added that the federal government must also send resources immediately to respond to the emergency. 

According to Cota, the federal government’s attitude regarding this situation is regrettable.
“The federal government is not offering the necessary resources to assist the rural zones that have been damaged by this situation. The government must destine resources to the affected states, not only to the states that are holding elections,” Cota said. 

The National Meteorological Service (SMN) said that the states that have been most severely affected are: Baja California, Baja California Sur, Sonora, Sinaloa, Chihuahua, Durango, Coahuila, Nuevo León, Tamaulipas, Jalisco and Guanajuato. 


The cold temperatures in northern Mexico earlier this year and the recent drought have devastated this region. If actions are not taken soon, Mexico’s food supplies may be endangered. 

Cota said that the drought will have a higher impact than this year’s freezing temperatures. Droughts are more serious because they can cause wildfires and death of livestock, which would cause a food crisis in Mexico.

Water for Humans Spring Newsletter: April 2011


Saludos from all of us at WFH (which means “Hi” in Spanish)!

Your steadfast support has made a big difference to people in Oaxaca, Mexico – mothers and fathers who are looking to WFH for help in giving their families safer homes and healthier lives.

They send their thanks and we join them: WFH exists because of you!

Some of you have asked me what WFH has achieved so far in 2011. The answer is…a lot!

Meet Ofelia Carrada Maribel Lopez

Last year, your gift provided key seed funding to plan a new sustainable water treatment facility in Santo Domingo Barrio Bajo Etla. Until we reach that important goal, WFH is working in small ways to help the community access clean water.

Professor Ofelia Carrada Maribel Lopez teaches 3rd grade at Valentin Gomez Farias Elementary School, located in the village. Prof. Ofelia said, “Sometimes when you run out of waterjugs and children are still thirsty, they have to drink water from the tap and this causes many diseases.” She tells us that clean filtered water from the tanks already in place would allow the school to stop buying expensive bottled water – and spend the money instead on school supplies.


How is WFH helping Ofelia and her students?

WFH, with full participation from INSO, is raising funds to install filtration systems on the elementary school’s water tanks. Estimated Project Cost: $500 


Meet Ines Avelina Barroso 

Donations like yours are making it possible for WFH to reach into new communities. Ines is a new community partner in the Victor Bravo Ahuja district of the municipality of Santa Lucia del Camino in Oaxaca City. She wrote to Water for Humans and INSO and asked for our help solving her neighborhood’s chronic water shortages.

This is what Ines told us: “Our neighborhood was a landfill and quarry before becoming a residential district. Originally, water service consisted of two spigots; over time, the delivery system was expanded. Now, due to the population growth it is extremely insufficient.  Last year, during the dry season most residences received water only two times per week for few hours per day. The water…is not potable.”
 


How is WFH helping Ines and her family?

Together with INSO, we have designed 8,000-gallon rainwater catchment systems – a pilot project to be tested in eight homes in the neighborhood homes. WFH submitted a grant proposal on May 2 to the Seattle International Foundation to fund this innovative, low-tech, sustainable solution. Estimated Project Cost: $6,000

On the ground with Nelly, WFH staff in Oaxaca

Your contributions in 2010 made it possible for WFH to hire a half-time staff member in Oaxaca – Nelly Fernandez Tellez. We are grateful (and Nelly is, too)!

Nelly gives WFH a human face – something difficult to do when an organization is headquartered thousands of miles away. She makes sure that community partners in Oaxaca – organizations like INSO and individuals like Ofelia and Ines – have someone they can talk to. Nelly also provides us with critical, on-the-ground updates about the changing situation in Oaxaca.

Recently, Nelly told us:
  • The election of Daniel Ramirez in Villa de Etla means the treatment plant project will go forward.
  • The newly elected mayor of Santa Domingo Barrio Baja Etla, Severo Jesús Santiago Ruíz, is a close confidant of the prior mayor, Maria Soledad Diaz Gonzalez, one of WFH’s greatest champions in Oaxaca.
  • Ex-mayor Diaz met with State Water Commission Rolando García Rodrigo Varela to bring him up to speed on status on replacing the derelict treatment plants in Santa Domingo. During the meeting, he committed his support for our approach and project, which is another key milestone for us.

In Seattle with Rick and Stan

Your assistance motivates WFH’s co-founders, Rick McKenney and Stan Brown to keep focused on the mission: provide low-cost, clean water solutions to underserved populations while ensuring that water remains a local, public resource.
Rick reports, “Seattle University law students, Misha Sandusky and Joe Helt, are working to complete our Federal IRS 501(c)3 paperwork, as part of a course led by Judy Andrews on nonprofit legal issues.” This is an important step in WFH’s growth and stability (although we continue to be gratefully to our fiscal sponsor, A.W.I.S.H).
Stan adds, “We have recruited eight board members, twelve advisers and nineteen dedicated volunteers (in the areas of translation, marketing, development, economics, web development, public health, environmental engineering and cultural affairs).”
Want to volunteer and help the people of Oaxaca? Just contact Rick RickM@WaterforHumans.org or Stan StanB@WaterForHumans.org

What’s next for WFH?

Watch your email inbox in the coming weeks for an important announcement: WFH is partnering with crowdrise.com, an online social networking and philanthropy website, in an innovative fundraising campaign to make sure that Ines and Ofelia’s dreams come true.

Thank you!

You are a person who cares about the world we live in and have demonstrated that by supporting Water for Humans. Our new friends in Oaxaca’s Central Valley say, “Muchas gracias!”

 PS: You can stay in touch with the Water for Humans team by reading our blog or following us on Facebook – almost 300 people already “like” WFH!

Community Well Water Analysis in Santo Domingo Barrio Bajo Etla

From Nelly Fernandez Tellez Water for Humans-- Mexico Operations

On 25 April, I paid a visit to the community of Santo Domingo Barrio Bajo Etla.


I was there to obtain a copy of the results from annual analysis of community well water conducted last year, and to talk with the manager of the water committee.


Initial results show the water is fairly good quality, however the well pump failed last year and the new replacement pump is starting to show some corrosion.  Currently, the municipality does not have the funds to perform new water analysis, and they have asked Water for Humans to help them determine the root cause of the pump failure and better understand the water quality.

In response we are invigorating the costs of performing a more complete water analysis, and forecasting the funding requirements to support this request.

Water testing at the School in Santo Domingo Barrio Bajo Etla

MARCH 22, 2011.
By Our Oaxaca staff  Nelly Fernandez Tellez
I made a visit to the school in Santo Domingo Barrio Bajo Etla meet with the head master; Valentin Gomez Farias to test the water quality, receiving the parameters measured were: pH, hardness, alkalinity, dissolved oxygen, iron, manganese, salmonella, E. coli, Aeromonas and other coliforms.

 
These tests were made because "Water for Humans", aims to get to install filters at school, and thus the school can stop buying jugs of water. The children will be able to drink water straight from the tap and the money save will be used to invest in material for children or school improvement in general.


 
The results were quite favorable and we can say that although the water is clean, We do not feel nor do the children & staff feel safe drinking untreated water. This is because none of the incoming well water is treated or inspected on a regular basis.  Thus we hope to install a water purifying filter to ensure the greater safety of the children and staff.
