Everything You Need to Know About Dry Flush Toilets

Dry Flush ToiletsDry flush toilets is a term that likely conjures up images of unsanitary, foul-smelling contraptions. But, in reality, they are quite the opposite. Revolutionary and effective, they have even caught the eyes of the Bill and Melinda Gates Foundation as a promising solution to the life-threatening sanitation-related diseases, such as cholera and diarrhea. These diseases are faced by the 2.4 billion people around the world who still lack access to clean running water.

How do Dry Flush Toilets Work?

Multiple companies have developed dry flush toilets. Perhaps the most notable development is Cranfield University’s Nano Membrane Toilet.

First developed in 2014, the toilet “flushes” by using a waterless rotating scraping mechanism that separates solid waste from liquid waste. Nanofibers, arranged in bunches inside the chamber, then help to condense the water vapor generated by the urine. They condense it into a tube that eventually flows to a tank externally connected to the toilet. By then the water will have been thoroughly filtered and, as a result, is then suitable for everyday use.

Solid waste, on the other hand, is transported into a combustor. This converts them into energy and ash, via a mechanical screw. The energy then powers the toilet’s future “flushes.” The energy can also charge electronics.

Award-Winning Functionality

Dry flush toilets are designed for daily usage. It can accommodate up to ten individuals daily. The toilets are manufactured at the cost of $2,500 per unit. They can last for up to ten years. The product is still undergoing product and product implementation testing. Researchers have reported promising results from their first phase testing in 2014. They conducted the phase in Ghana. According to their survey, “people seemed very open to most of the concepts around the toilet.”

Since the beginning of its development, the ingenious invention has received an accolade of prestigious awards including the Kiran and Pallavi Patel Grand Innovation Award as well as the Excellence in the Field of Environmental Technology Research from the CleanEquity Monaco.

Challenges

The most prominent challenge facing the implementation of dry flush toilets in developing countries is likely scalability. Communities that choose to implement the contraption would have to have a team of specially-trained technicians to safely maintain the toilets.

Another question is regarding how the toilets would be distributed. Currently, the best path is to rent them to households at either a monthly or weekly rate. This is an approach that companies with similar products employ, such as Loowatt’s waterless toilet. Renting these other products has reflected great success.

In addition, the team is working to make the toilet more affordable, with a goal of a final cost of five cents per person per day.

Another anticipated challenge to dry flush toilets is overcoming cultural barriers. While most Africans prefer Western-style seat toilets, squat toilets are far more common and desirable in Asia.

An Innovation to Aid Impoverished Communities

Conclusively, although still emerging from the prototype phase, dry flush toilets very much so have the potential to change millions of lives within a short period of time from implementation. By ensuring that every individual on this planet has reliable access to a flushing toilet, millions of bases of water-borne diseases can be avoided each year.

10 Facts About Life Expectancy in Kenya

10 Facts About Life Expectancy in KenyaLocated on the mid-eastern coast of Africa, the nation of Kenya is home to more than 50 million people. Despite the country’s strong tourism industry, which centers around internationally renowned landmarks such as the Musai Mara National Reserve, it still struggles with issues pertaining to extreme poverty.

One of the main effects resulting from this poverty is a very low life expectancy rate. The inverse relationship between wealth and life expectancy is largely due to the nature of poverty. For instance, the inability to see a doctor, access contraception, buy medicine, etc. all compound the chances of early mortality. Poverty has impacts beyond general health too, like exposing people dis-proportionally to unsafe living conditions.

This informs the reality in Kenya, where people over the age of 65 make up only 2.7 percent of the population, and the average life expectancy is only 59 years. Here are 10 facts about life expectancy in Kenya to help explain why that number is so low.

10 Facts About Life Expectancy in Kenya

  1. High poverty rates: More than 50 percent of people live below the poverty line. In addition, in Kenya, 40 percent of people live on less than two dollars a day.
  2. High child mortality rates: The under 5 mortality rate in Kenya lands at 85 deaths per 1,000 births. This number is dramatically higher than the global average of 40. This is a huge issue, as the World Bank claims the number one way to increase life expectancy is to reduce child mortality.
  3. Number of physicians: There is one doctor for every 10,000 people in Kenya. In addition, the country’s health care system has historically been dysfunctional. This manifested into a 100-day strike in 2017 by doctors over poor working conditions and pay. It was followed, late that year, by a nurse’s strike for similar reasons. This has led to overloaded and under-resourced facilities, which dis-incentivizes people to go into the field.
  4. Lack of admittance to public hospitals: Because of the disorganization in the public health system, almost no patients get admitted into Kenya’s public health facilities. This creates an especially tremendous impact on the maternal mortality rate, as women do not have access to proper birthing spaces. This is one unfortunate truth in the 10 facts about life expectancy in Kenya.
  5. Lack of medical student retention: The presence of a broken health care system establishes a negative image of the medical field in Kenya. Therefore, 40 percent of Kenyans who graduate with medical degrees choose to find work elsewhere. This furthers the national shortage, preventing millions of people from having access to medical needs.
  6. Lack of access to clean water: While millions of people in first world countries do not stop to think about how much water they use on a daily basis, around 60 percent of Kenyans do not have access to clean water. Thus, there is an extremely high nationwide risk of contracted water-borne diseases such as malaria, cholera and typhoid fever.
  7. No universal health care system: Kenya’s government does not offer a universal health care system, so millions of people are uninsured. On account of this, many avoid clinical care–which is oftentimes necessary. Under this system, small treatable issues tend to develop into potentially fatal diseases.
  8. Poorly kept health facilities: Since the government lacks adequate funding to keep the hospitals clean and sanitary, many fall into disrepair. Additionally, the lack of resources creates a shortage of medical equipment and a poorly operated management system.
  9. Kenya Quality Model for Health: In 2018, Germany’s Federal Ministry for Economic Cooperation and Development partnered with the group Amref Health Africa to create a set of national health standards called the Kenya Quality Model for Health. Currently, workers are being trained in KQMH nationwide in over 47 facilities, while they receive monthly visits from Amref trainers. This program will hopefully improve the quality of care in Kenya and in turn life expectancy.
  10. Expansive treatment measures are being implemented: The lack of health care access mainly centers around rural western Kenya, where transportation is frequently an issue. In 2018, the Academic Model Providing Access to Healthcare (AMPATH) joined with the Abbott Fund to help solve this problem. The partnership has trained more than 1,000 workers to deliver doses of insulin to people with diabetes mainly in western Kenya. They have also invested $5 million to screen people for diabetes and provide them with the proper medical instruments. This unique approach to health care will hopefully expand to other treatments, decreasing the number of people who do not receive care.

How PortaPure Provides Clean Water in Haiti

PortaPure

The company PortaPure began research on water filtration systems after a massive hurricane hit Haiti in 2010. Millions of people were left without clean water. By Christmas of that year, PortaPure began donating their PocketPure devices. Today in Haiti, where the company PortaPure still does most of their work, 60 percent of the population are still living in poverty. They do not have easy access to clean water. Although there are other solutions to clean water, those solutions can be expensive. To continue its mission to provide access to clean water all around the world, PortaPure has created multiple solutions that can help in their goal.

Efforts to Aid Haiti

After the earthquake hit Haiti in 2010, PortaPure was not the only organization to invest in providing access to clean water. The U.N. came to help as well. Unfortunately, their sewage leaked into a clean source of water that contaminated it. Consequently, the leak exposed the Haitians to cholera. About 800,000 Haitians became sick from drinking and using water from the contaminated source.

The need to solve this problem was even more apparent after 10,000 people had died from cholera, so PortaPure knew their filtration system needed to be able to filter this out.

Their filtration system has the water pass through a series of filters that, in the end, filters down to .02 microns. This level allows for diseases, like cholera, to be filtered out and safe to use.

PocketPure Offers Clean Water to Drink

PortaPure’s first innovation, PocketPure, was meant to be a cheap solution to provide developing countries access to clean drinking water. It is meant to be very portable, pocket-size, as it weighs less than a pound. Even though it is portable, it still allows the user to drink one liter of water.

This is one of the cheapest innovations on the market as it costs less than $20. PocketPure’s affordability allows for more people to be able to donate these systems to developing countries. Although this price might still seem like a lot, other filtration systems can be as much as 100 dollars.

PureLives in Africa

African families compared to families in first-world countries use much less water. Families in developed countries can use up to 550 gallons of water per day while African families use about five gallons per day. One of PortaPure’s most recent products, PureLives, addresses the need for a large amount of water.

PureLives is a water treatment system that can hold up to five gallons of water. This is just the right amount for families in developing countries. This water treatment system is also portable as it acts like a backpack, making it easier to carry water home if the water source is far away. Additionally, it is efficient as it can filter water into the system at a gallon per minute. The PureLives system also has a long filtration life as it can last up to three years or 5,000 gallons.

Although PortaPure’s mission was to provide access to clean water for Haiti, it has evolved into a global mission. There are 785 million people in the world without access to water service. Furthermore, two billion people use a water source that has been contaminated by feces. These contaminated water sources contain diseases, like cholera, and many others that contribute to 485,000 deaths per year.

Luckily, with inventions such as the PureLives system, PortaPure provides some cost-effective solutions that allow Haiti to have access to clean water.

3 Efforts to Improve Water Management in Armenia

Water management in Armenia

With 25.7 percent of the population living below the poverty line, the people of Armenia consider water a luxury. Armenians face daily water shortages and unclean water supply in their homes. Despite this, several groups are working together to improve water management in Armenia. Maintaining a stable supply of water is an important step in lowering poverty and improving the lives of citizens.

3 Efforts to Improve Water Management in Armenia

  1. Relief to Yerevan: The World Bank sponsored a $50 million project to make water more accessible to Armenians living in the capital city, Yerevan. Before the intervention, families would have access to water in their homes for approximately six hours per day, and the water was usually unclean. Now, 332,000 families in the capital have access to water for 21 hours per day, and thanks to nine new chlorination stations, the water is cleaner and safer. The World Bank also recognized the need to monitor the water supply to prevent waste, so they introduced a software program that oversees the entire network of pipes and water mains. The program makes it possible to pinpoint areas within the network that need renovation or attention to maintain a stable supply of water. This program could help thousands of Armenians if it were implemented in other cities, but so far, it has brought a sense of security and relief to Yerevan.
  2. Wastewater Treatment Methods: Before 2010, the wastewater treatment system allowed unsanitary water to contaminate agricultural lands, causing a jeopardized food supply and an increased risk of disease. In the village of Parakar, Global Water Partnership’s Armenia branch stepped in to reform the wastewater treatment methods. They chose a cost-effective technology that treats domestic wastewater so that it can be later used for irrigation purposes and vice versa. This allows water to be recycled and reused, promoting a message of sustainability. The treatment program also focused on public awareness of the new treatment technology, involving the community in the process which facilitated the plan’s success.
  3. Water Within Reach: Armenians used to have to travel very far to get potable water. Some families were forced to drive over an hour to get to the public tap, spending a large portion of their income on the expenses associated with this travel. The Asian Development Bank launched a project that aimed to reduce the cost of obtaining water by making it clean and available within people’s own homes, benefitting more than 600,000 people across the country. Having access to water in the home for at least 17 hours per day now costs $12 per month – significantly less than what it previously cost to make the drive to the public tap. This initiative marginally contributes to the decrease in poverty among Armenian families, and it improves the quality of their lives significantly.

The World Bank, the Global Water Partnership and the Asian Development Bank have changed lives because of their work to improve water management in Armenia. This is a small but mighty step towards decreasing poverty in Armenia.

Vitens Evides International and Clean Water Access

Vitens Evides International
Currently, over 660 million individuals around the world do not have access to clean, potable water. However, the Utretch, Netherlands-based organization Vitens Evides International (VEI) aims to change this. VEI partners with local companies to deliver clean water to individuals in transitioning and developing countries. Their work has already reached the lives of hundreds of thousands of people, as they have entered into productive partnerships with companies in Colombia, Ghana, Kenya, and Mozambique, among others.

Notable Partnerships

Upon entering into a WOP (water-operator partnership) both the local company and VEI get to work implementing technologies and strategies to help improve water quality and accessibility. One of VEI’s most successful partnerships came in 2008, when they partnered with local company SAWACO in Ho Chi Minh City, Vietnam. VEI was able to successfully fix the issue of water system leakage in the city and improve clean water distribution. They were also able to train individuals in the community on how to maintain a functional, efficient water purification and distribution system, ensuring that the work done by this particular WOP had long-lasting impact.

Another notable partnership came in 2015 when VEI worked with FIPAG, a local water supply company in the city of Maputo, Mozambique. Their combined efforts to install new drinking water distribution centers and improve household connections to these centers has helped bring clean, potable water to many people residing in Maputo.

The Statistics

VEI’s yearly statistics are impressive. In 2018, they worked on over 40 projects in 20 different countries and helped over 300,000 individuals gain access to clean water. The number of individuals that have gained access to clean water as a result of VEI’s work has grown in 3 consecutive years; as such, VEI is aiming to help another 350,000 individuals gain access to clean water by 2020. The company has a strong vision and driven leadership at the helm. Given all of this, it seems VEI is set up for future success.

Sustainable Development Goals

VEI’s work helps to achieve UN Sustainable Development Goal #6, which is to ensure all individuals have access to clean water and sanitation. Accomplishing such a goal will help achieve a number of other Sustainable Development Goals (SDG’s) as well; having access to clean water helps to alleviate poverty and promote educational opportunities (SDG’s #1 and #4) as individuals will be able to spend more time working or obtaining an education and less time looking for water. In addition, individuals with access to clean water will be far healthier, which will contribute towards the achievement of SDG #3.

Future Impact

As mentioned above, VEI is looking to continue to make a positive impact on the lives of thousands of people across the developing world. They have recently secured partnerships with companies such as STUCO (Aruba) and WEB (Bonaire), as well as DWASA (Bangladesh). Each of these partnerships promises to contribute to the end goal of providing clean, potable water to everyone around the globe. Such a future may now be closer than ever.

3 Major Health Problems from Water Pollution

Health Problems from Polluted Water

Water—our lives depend on it, but for many people around the world, this essential, life-giving liquid brings disease and even death. Today nearly one billion people have limited access to safe, clean water because of pollutants from inadequate sewage systems, industrial dumping, agricultural run-off and irresponsible manufacturing practices. The result? More people die every year from water contamination than war and other forms of violence combined. Each year, around 840,000 people die of health problems from water pollution.

3 Health Problems from Water Pollution

1. Diarrhea: The most common health problem from water pollution, diarrhea causes loose, watery stools, abdominal pain, dehydration and even death. Diarrhea is commonly caused by drinking, cooking or cleaning with water contaminated by feces. In India, a country where roughly half the population practice open defecation, diarrhea is the third leading cause of death in children under the age of five. In 2015, diarrhea killed an estimated 321 children every day in India. However, India is making efforts to prevent and treat diarrhea. In 2014, the country approved the Integrated Action Plan for Prevention and Control of Pneumonia and Diarrhea (IAPPD), with one of its main focuses being to provide safe drinking water and improved sanitation to Indian households. Since its adoption of IAPPD, India has improved treatment cover to those with diarrhea, launched immunization campaigns to treat diarrheal disease, and as of 2018 constructed household toilets in 52.16 percent of the IAPPD’s targeted 12 million rural Indian households. Because of these efforts, deaths of children below-four children in India have decreased by 52 percent over the last several years.

2. Cholera: Contracted by consuming contaminated water or food, cholera’s main symptoms are severe diarrhea and vomiting which leads to dehydration. There are an estimated 3-5 million cholera cases every year and the World Health Organization (WHO) reports that 54 percent of all cases are from developing countries in Africa whose inhabitants lack access to safe water, basic hygiene and sanitation facilities.  The Lake Chad Basin, which includes Nigeria, Niger, Mali, and Cameroon, reported that in 2018 there were eight times as many cholera cases compared to the previous four years in that region, with more than 23,000 people affected and over 388 deaths. In response to the increased cholera outbreaks in Africa, GAVI the Vaccine Alliance, along with WHO and the Global Task Force on Cholera Control (GTFCC), launched a massive vaccination drive throughout five African regions to help treat and extinguish further epidemics. Between 1997 and 2012 only 1.5 million doses of cholera vaccines were administered worldwide, but thanks to the vaccine drive, in just the first four months of 2018, 15 million cholera vaccines were approved for administration. The vaccine drive is part of a global initiative to reduce cholera deaths by 90 percent by the year 2030.  Dr. Seth Berkley, CEO of GAVI the Vaccine Alliance, shares that despite the vaccine drive’s importance in addressing the outbreaks, improved water and sanitation is “the only long-term, sustainable solution to cholera outbreaks.”

3. Dysentery: Dysentery is an inflammation of the intestines. Its symptoms include bloody diarrhea, fever, abdominal cramps and even excreting large portions of the intestinal membrane. Like many other health problems from water pollution, dysentery is spread through fecal-polluted water, and mainly impacts impoverished communities who rely on makeshift sewage systems and contaminated water sources for sanitation and drinking. Dysentery can be a major concern in refugee camps where insufficient and overwhelmed sanitation facilities and open-air sewage dumping become a breeding ground for water pollution diseases like dysentery, as the recent Rohingya refugee crisis in Bangladesh revealed. Dr. Samir Howlader, National Program Officer for Migration Health at the International Organization for Migration (IOM) reported that when the Rohingya refugees—over a million people have fled their homeland of Myanmar to seek refuge in Bangladesh—first arrived in the Bangladesh camp of Cox’s Bazaar in 2017 there were “effectively no facilities” for the new arrivals and dysentery was a common concern. In 2019 however, the UN’s refugee agency, UNHCR, made it possible for the largest-ever refugee camp sewage treatment plant to be constructed in Cox’s Bazaar. The now-operating plant treats the human waste of 150,000 people every day, protecting the refugee community from the previous dangers of sewage-contaminated water. Medical clinics set up in the camp by the International Organization for Migration (IOM) have also helped treat and eliminate dysentery from the community. Since 2017, over one million refugees have received consultations at IOM clinics, and Rick Brennan, director of emergency operations for WHO states that there has not been any significant increase in disease thanks to these diligent efforts.

Though health problems from water pollution claim too many lives each year, great progress is being made towards a solution. The UN reported that over the last two decades, 2.6 billion people gained access to an improved drinking water source.  Now more than ever there is hope as the global community and developing nations work together to address water pollution problems and create a world where everyone has access to safe, clean water.
