Liquid System Update

North Carolina, United States

A new fully automated Beta 2.0 system was recently installed at the RTI testing laboratory in the US.

This biggest change for the liquid system was a redesign of the baffle tank. The new design helps to direct flow away from the outlet. This new system has been up and running for 65 days and has processed over 10 kg of feces and 100 L of urine.

We will continue to test in this new system to develop and refine processes that allow us to not only disinfect the effluent, but meet social expectations and discharge standards.

The video below shows a flush with green food coloring being followed by a flush with water in the new tank.

“The power of 10: Ten astonishing facts about 10-year-old girls.”


Investments in health, education and empowerment of 10-year-old girls can triple a girl’s lifetime income.  This and 9 other facts about adolescent girls are highlighted in this United Nations Population Fund Report summary.  The full report on the State of World Population 2016 emphasizes that the welfare of these girls will have an enabling impact on the Sustainable Development Goals unanimously adopted by the United Nations in 2015.

In the Reinvent the Toilet Challenge, our team and partners at the Bill & Melinda Gates Foundation have a commitment to developing sanitation solutions for men and women, girls and boys, however in many parts of the developing world that lack access to safe and effective sanitation, gender discrimination disproportionately impacts women and girls.  We believe that by focusing on the needs of adolescent girls, empowering them with better options, a virtuous cycle will be created that improves overall quality of life for girls, their families, and generations to come.

Below is a short video about a 12-year-old girl in India, highlighting the importance of including women and girls directly in the product design, education and business aspects of providing sanitation solutions.

“ISO’s two-step solution to improving sanitation for 2.4 billion people”

Providing sanitation for every human on the planet by 2030 is going to take a Herculean amount of effort. Many projects just like our own, have discovered tough barriers that have to be overcome in order to improve global sanitation. As with any multi-tiered effort, when groups work together and share their solutions, we all benefit from our past collective wisdom. But that wisdom is only as good as it’s universal availability.

That’s where developing standards come in. recently (November, 2016) published an article documenting a “two-step solution to improving sanitation for 2.4 billion people” (ISO 24521). The post is a great description/example of how standards can help aid with valuable advice on “…training users and operators, evaluating risks and designing and building basic on-site domestic wastewater systems, including alternative technologies that can be set up using local resources. ISO 24521 can be used by both publicly and privately operated sanitation wastewater services for one or more dwellings, regardless of the type of facility model.”

“The demand for this guidance came from government agencies looking to bring sanitation services into many rural and some underprivileged urban communities that do not have such infrastructure, or that have it but do not know how to manage it and offer better services to their users,” explains Gerryshom Munala, Convenor of the working group that developed ISO 24521.

There are other published standards documents as well! Some of which, members of our project have provided valuable input. Here’s one we recently published in August, 2016: Non-Sewered Sanitation Systems: General safety and performance requirements for design and testing.

“The Next Challenge for Cities: Integrating Multiple Sanitary Solutions”

The infographic below was recently published by

Like any well made infographic, it shows the increasing sanitation challenges our cities face as they continue to grow exponentially. It also shows possible solutions, as well as the consequences of doing nothing to address the growing lack of sanitation in our cities.

We encourage you to have a good look at it below.

“USAID Announces Partnership with Toilet Board Coalition”

Huge news emerged from this years World Toilet Day in the form of a global alliance between USAID and Toilet Board Coalition.

“The new Global Development Alliance between USAID and Toilet Board Coalition will pool USAID’s extensive sanitation expertise and global reach with the Toilet Board Coalition’s business expertise and private sector resources to accelerate progress toward SDG 6 by using market-based approaches to identify best practices for sustainable sanitation improvements, and then implementing those interventions at scale.”

USAID put a up a thorough post on their Medium site dictating the current state of sanitation on our planet, the obstacles in the way, and how this new alliance will endeavor to get past them.

There’s a lot of good information in this post, including a great podcast interview with Toilet Board Coalition Executive Director Cheryl Hicks.
