Field testing of an onsite sanitation system on apartment building blackwater using biological treatment and electrochemical disinfection

STeP or Partner: STeP, Duke Center for WaSH-Aid, California Institute of Technology, Kohler Co.
Country of focus: India
Published date: April 2020

Brief description:

The Closed Loop Advanced Sanitation System (CLASS) was designed to treat, disinfect, and recycle toilet blackwater from existing flush toilets in a multi-story apartment building. Two systems were tested at two unique sites in Coimbatore, India for a combined 7500+ treatment hours resulting in more than 180 000 L of treated water. The CLASS prototypes used a combination of biological pretreatment and electrochemical oxidation processes to produce treated water that nearly met the stringent requirements outlined in the standard ISO 30500. The nutrient and organic loading from the toilet blackwater was predominantly reduced by over 85–95% and 80–87%, respectively, through biological processes that were achieved using either a sequencing batch reactor (SBR, site A) or an anaerobic–aerobic biodigester (EcoSan, site B). Complete disinfection of E. coli with nil CFU per ml was achieved using electrochemical processes that also served to remove the remaining organic and nutrient loading to over 90–96%. The treated water was reused for flushing by the residents of the apartment building for 89 days.

Key topics

  • Field testing
  • CLASS system

Country of focus: Senegal
Published date: April 2020

Brief description:

This report captures lessons learned by DELVIC Sanitation Initiatives in preparing for the commercial field test of the Janicki Omni Processor, a fecal sludge waste-to-resource technology. While DELVIC is based in Senegal, the lessons they have learned may be useful to others planning commercial evaluations of fecal sludge waste-to-resource technologies in other contexts.

Key topics

  • Treating fecal sludge as feedstock, not waste
  • Navigating the permitting process
  • Selecting and developing by-product sales channels
  • Preparing for the capital raise
  • Executing the capital raise

Conducting User Studies for the Reinvented Toilet: Applying User-Centered Design in the Field

This guide is aimed at helping technology providers, commercial partners, or those new to the process of conducting user studies understand the importance of and how to conduct user studies for Reinvented Toilet (RT) development. At their core, user studies build insights around users and potential users of a system or technology in order to ensure that users may be willing to use the product once it enters the market. Engaging users early in the design and product engineering process helps to enhance market entry success, beginning with initial adoption of a product and its sustained use. This resource guides readers into important steps and considerations for conducting sanitation-focused user studies, including user study planning, preparation, data collection, analysis and action (translating findings into product design).

On-Demand Webinar: Business Model Insights for Emerging Sanitation Technologies

In complex sanitation markets, successfully commercializing emerging sanitation technologies proves to be as much about a company’s business model as its technical offering, especially for those companies targeting bottom of the pyramid markets. At the same time, understanding how to identify, test, and refine business model ideas poised for market success and social impact can be daunting. Where do you start? What factors should you consider? What tools and resources are available to support you in this process?

STeP’s webinar entitled “Business Model Insights for Emerging Sanitation Technologies” shares our experience tackling these questions for an emerging class of sanitation technologies: The Reinvented Toilet.

The webinar addresses the following topics:

  • Why do business models matter for the sanitation sector?
  • What is unique about the Reinvented Toilet that needs to be represented in emerging business models?
  • What ideas for Reinvented Toilet business models might you consider as a starting point?
  • What else beyond business model innovation is needed to ensure sustainable, high-impact market-based sanitation solutions?

On-Demand Webinar: Reinvented Toilet Pilot Playbook – How to Select a Pilot Site

Join the STeP team for an on demand webinar on the importance of pilot testing. Not only is a pilot test a safe place to fail when introducing new technology, it’s a critical first step before going to market or implementing a program, and often saves organizations time and money.

In this on-demand webinar, host Kate Bronstein presents the Reinvented Toilet Pilot Playbook  and highlights best practices that help technology developers and early adopters plan effective pilot tests to increase  a new technology’s chance for a successful launch. Drawing from  the concept of  design thinking, the Playbook is framed by three overlapping  priorities – viability, desirability, and feasibility – that inform technology  design, product launch, and scale-up  to reduce the risk of failure.  We explain a six-step process for defining organizational priorities and selecting a pilot site. At the conclusion of the webinar, participants will know what information is needed to

  • define organizational  priorities and test business models;
  • identify which locations may be viable for target markets;
  • select a pilot site given technological needs, user community, and other criteria important to the product and business model.

Fecal Sludge Treatment Technology Decision Support Trees

STeP or Partner: STeP
Country of focus: India
Published date: January 2020

Brief description:

As municipal decision-makers consider available treatment solutions for managing fecal sludge waste streams, critical factors such as land availability and cost, the importance of water reclamation and complete pathogen destruction may influence selection of one technology over another. Based on city archetypes and key value drivers identified in STeP’s Market Insights for the Omni Processor, along with cost drivers identified in STeP’s Techno-Economic Analysis (TEA) of Model Fecal-Sludge Management and Sewer-Based Systems in India, these decision trees can serve as a starting point for selecting best-fit FS treatment technologies.

Key topics

  • Omni processors
  • Fecal sludge treatment technologies
  • Technology selection

Reinvented Toilet Pilot Playbook – Streamlined Guidance for Technology and Commercial Partners

STeP or Partner: STeP
Country of focus: Global
Published date: January 2020

Brief description:

Newly introduced technologies  fail for many reasons. These include  low  user adoption,  a misunderstanding of the target market, and an unsound business model.

A pilot test can be a safe place to fail. The pilot can serve as a critical first step before going to market or implementing a program, and often saves organizations time and money in the long run.

The Reinvented Toilet Pilot Playbook (Playbook) brings together best practices in designing pilot programs and answers questions including:

  • How do I know what to pilot and when?
  • How do I design a pilot?
  • Where should I pilot test my solution?
  • Key topics

    • Decision support
    • Pilot test site location
    • convergence of late-stage technology readiness with pilot testing for product/program launch
