Replicable, sustainable, and scalable.
Our technologies are the most environmentally friendly and sustainable in the world of water security. Each of the seven technologies create a set of climate-friendly co-benefits that simultaneously improve the social, health and economic aspects of village life leading to stronger communities, fewer internally displaced people, improved cultural preservation, and newly discovered opportunities.​

Water Security

Issue:  Lack of a reliable water source. 

In developing countries, there is often no water in the home or at school. Forty percent (40%) of global healthcare facilities have no water service. Water sources have become unreliable due to unpredictable rain patterns brought on by deforestation, over-drilling of wells, and climate change. These climate impacts disproportionately impact developing countries. Water sources are no longer sufficient, and those that exist are frequently shared between people and animals. 

Solution: Rainwater Harvesting with Rainwater Catchment Tanks

Our Water Security Program is designed to make villages more resilient by creating secure and sustainable local water capacity. We train communities to build their own water storage using custom-designed and government-approved Rainwater Catchment Tanks. Each Tank holds over 6,600 gallons (25,000 Liters) of water, is built by villagers with locally made, curved bricks, and can provide year-round water for people and agriculture, refilling multiple times per year. 


Rainwater Catchment Tanks (RCTs):

Friendly Water helps villages build community Rainwater Catchment Tanks with a capacity of 25,000 Liters each. The technology is easy to scale. 


  • Villagers now have a reliable water supply.
  • Women and girls no longer have to spend hours a day searching for water from ever-increasing distances over often dangerous roads.
  • Girls are able to stay current in their education. 
  • New employment opportunities are created for local workers. 
  • There is no need to drill and maintain expensive wells.
  • Other communities can see the benefits of our Water Security training and production programming.


  • Girls, who can now stay in school, don’t fall behind their peers.  Graduation rates improve and teen pregnancies decline.
  • Weather patterns no longer determine village life. 
  • Villages are more resilient and secure.
  • Community pride grows.
  • Unpredictability is replaced with certainty, and stress is reduced.
  •  Fragile watersheds are protected and restored.
  • Wages created through RCT construction expand opportunities for villagers, and empower communities.
  • Women can expand the scope of their lives beyond a daily search for water to start businesses or expand their small farms. 

Clean Water

Issue: Lack of safe drinking water. 

According to the United Nations, 2.2 billion people still lacked safely managed drinking water services in 2022. Most rural illness, including cholera and Ebola, begins with contaminated water. 

Solution: High-quality, hollow-fiber, ribbon technology water filters.

Our Clean Water Program focuses on the adoption and use of water filters in homes and schools. 


Water Filters:

Friendly Water’s bulk purchasing ability and table-banking program allow for the rapid introduction of hollow-fibre ribbon filter technology into any community challenged by access to clean and safe water. 


  • Intestinal illnesses are significantly reduced in households and schools that utilize ultrafiltration technology.
  • Families spend less time in clinics and more time in school or at work.
  • Money spent on medications can be used elsewhere.
  • The sale of water filters in the villages enables to Community Based Organizations (CBOs) to earn money for addressing other village initiatives.


  • Improved educational achievement.
  • Improved work attendance and performance.
  • Unencumbered by repetitive illnesses, families can plan for a future without constant sickness. 
  • Reduced stress on caregivers. 
  • Improved economic future.

Good Hygiene

Issue: 3 Billion people lack basic handwashing facilities. 

Lack of soap products, and counterfeit or highly-diluted soap failing to prevent disease transmission. Contamination by pathogenic microbes due to lack of quality, affordable soap.

Solution: Kenyan Bureau of Standards (KEBS) certified, high-quality, multipurpose soap production and sales.

Teaching villagers the mass production, distribution and sale of certified, high-quality multipurpose liquid soap to reduce disease transmission, increase positive health outcomes and provide opportunities for positive economic impacts. 


 Multi-purpose soap:

In an environment plagued by counterfeit or highly-diluted soap, our KEBS certified liquid soap, designed by a chemical engineer on our team, offers a high quality and affordable product to the community.


  • Disease transmission is greatly reduced.
  • Soap making and sales create jobs and local wages.
  • Schools are able to remain open, creating a safe environment for learning. 



  • Village resilience is affirmed and strengthened.
  •  Villagers take pride in their “hometown” industry.
  • Improved educational outcomes.
  • Fewer illnesses in the community. 
  • Money spent on antibiotics and clinic visits can be repurposed for non-emergency needs.
  • Economic opportunities are created.
  • People unable to find employment elsewhere due to infirmity or developmental issues find a welcoming environment in which to prosper and find purpose.

Improved Sanitation

Issue: Poor waste disposal and sanitation 

According to the United Nations, 1.9 billion individuals still lacked basic hygiene services in 2022. Villagers in the communities where we work primarily use open defecation and pit latrines (which introduce sewage directly into the watershed). Poor sanitation contaminates drinking-water sources, with fecal contamination driving many water-borne illnesses and spreading disease among the wider population. 

Solution: Desiccating Toilets

Friendly Water trains communities to construct off-grid and odor/fly-free desiccating toilets that naturally process waste. The toilets can be constructed using our Interlocking Stabilized Soil Blocks (ISSBs), with the output providing pathogen-safe compost for agricultural use. 


Desiccating Toilets

High quality, dual chamber desiccating toilets, constructed with Interlocking Stabilized Soil Blocks (ISSBs) and built at ground level.


  • A significant decrease in the incidences of fecal to oral pathogenic microbe transmission like typhoid and cholera, as well as other pathogens and intestinal parasites.


  • Improved sanitation is a basic necessity to guarantee the continuity of successful village life.  
  • Creates a heathier and safer community.
  • Fewer illnesses mean better work attendance and performance, leading to a more secure economic future.

Better Building

Issue:  Deforestation and watershed destruction.  

Every year, sub-Saharan Africa loses hundreds of thousands of acres of critical forest in order to produce fired bricks. These forests protect watersheds and are vital to hydrological restoration and preservation.

Solution: Interlocking Stabilized Soil Blocks (ISSBs)

Friendly Water trains communities in the production and use of Interlocking Stabilized Soil Blocks (ISSBs) for construction projects. These sustainable and eco-friendly blocks replace the traditional fired brick while creating good paying jobs. Producing ISSBs does no harm to our environment. Rainwater Catchment Tanks or Housing made from ISSB are easy and simple to construct.



Interlocking Stabilized Soil Blocks (ISSBs)

Used in construction of Rainwater Catchment Tanks (RCTs), homes, schools and more, the Interlocking Stabilized Soil Block (ISSB) is a revolution in the production of inexpensive, durable and environmentally friendly building materials.


  • Construction materials are replicable and easy to produce. Each pressed block is identical to the block before and the block after, allowing for stronger, studier, and reproducible construction practices.
  • Reduced deforestation – Since these blocks are not “fired” like traditional bricks, the need for wood fuel is significantly reduced.
  • Reduced production of pulmonary irritants and antagonists in the village air.


  • Quality housing is easier to afford and obtain. 
  • Pride in the village is increased.
  • Teaching villagers the design of ISSBs creates increased knowledge within the community.

  • Rainwater Catchment Tanks are built with ISSBs, providing for Water Security.
  • Improved quality of life for the entire community.
  • Creates the opportunity for a sustainable economic enterprise.

Sustainable Food

Issue: Lack of water for gardening and farming.

Unreliable water sources make gardening and farming unmanageable, which in turn leads to internal political strife as villagers search for water sources beyond the boundaries of their community.  

Solution: Permagardens

Friendly Water helps people get the most from their small-plot gardens by sharing permaculture principles that empower households, increase yields up to 3x, and can help provide a dependable food source year-round. 



The Permagarden is a simple to produce, highly efficient, and easy-to-maintain replacement for the traditional kitchen garden. 


  • Year-round gardening: Due to the water storage capacity, crops may be grown year-round. 
  • Increased production: Because large amounts of natural fertilizers are amended deep into the soil, harvest sizes can double the production of the kitchen garden.


  •  Teaching permagarden techniques increases knowledge and skills in the community.
  • Villagers frequently collaborate with each other to develop these permagardens, helping to strengthen community bonds.
  • Villagers’ health and diet is improved from having a year-round source of fresh vegetables and fruits available to them.
  • By not using foreign made high-nitrogen fertilizers, which don’t improve the soil, local farmers save money, reduce dependence on foreign markets, save time hauling water, and produce more food than ever before. 
  • Surplus produce reduces food scarcity and creates easy opportunities for economic development.

Safe Cooking

Issue: High incidence of pulmonary disease among village women and children.

In rural parts of developing countries, there is an increased risk of pulmonary disease among women and children due to smoke inhalation from traditional three stone fires. Smoke from traditional cooking fires kill more people each year than malaria. The traditional fires rely on large volumes of charcoal, wood and kerosene – fuels that pollute the lungs of women and young girls and contribute to global warming.

Solution: Rocket Stoves

Friendly Water’s Safe Cooking Program helps communities transition from three-stone and other open cooking fires to much safer and efficient rocket stoves. We serve as a distribution point and an educational source for use of this technology, which produces 81% fewer emissions than an open fire and uses up to 71% less fuel.


Rocket Stoves


  • Reduced emissions: Rocket stoves produce 81% fewer emissions than an open fire.
  • Reduced deforestation: Rocket stoves use up to 71% less fuel than traditional stone fires.
  • Reduced incidence of pulmonary disease: Fewer cases of pulmonary illnesses associated with traditional, smoky cooking methods.


  • The daily burden of fuel collection is reduced, allowing village women more time to attend to their families, interests and business pursuits.
  • Fewer respiratory illnesses among women and children.
  • Reduced expenses from using significantly less fuel than traditional three-stone fires.
