The Container-Based Sanitation Alliance (CBSA) is the voice of Container-Based Sanitation (CBS) providers. Established in 2016, CBSA represents its members as a neutral, independent, not-for-profit association.

Our vision
We believe that with the right support, CBS services can scale to provide affordable, safe, and dignified sanitation to 50M people in LMIC by 2030, in line with SDG 6.2.

Our goal
CBSA promotes the use of CBS as a safe and essential component of blended, city-wide approaches to sanitation. Our goal is to help scale the adoption of CBS by public and private providers, customers, and governments in Low-and-Middle Income Countries (LMIC) cities. In order to maximise our impact, we regularly collaborate with other organisations to overcome barriers to growth of the CBS industry.

Our collective impact
At April 2023, CBSA members:

  • Serviced 13,455 CBS toilets
  • Served 253,847 people
  • Provided over 514 jobs
  • Operated in 24 municipalities

In 2022-23:

  • 17,757 tons of sludge removed
  • 18 global events spoken at
  • 73 new articles containing “container-based sanitation”


The CBSA helps CBS to scale farther, faster through the following core focus areas:

Global advocacy: Advocating for the adoption of CBS by funders, investors, and LMIC governments, municipalities, and utilities through the promotion and dissemination of data-supported evidence, case studies, and success stories. Advocacy efforts are focused on establishing CBS as a critical component of blended, city-wide approaches to sanitation.

Member support: To help its members overcome commonly experienced issues and challenges that slow the path to scale, and enable collaboration, learning, and sharing across CBSA members, the CBSA organizes and facilitates knowledge exchanges and develops and disseminates related knowledge products.

Research and insights: Building the evidence-base for CBS by developing robust evidence and analysis that help overcome industry and sectoral knowledge gaps and address key issues that slow the path to scale.

Fostering innovation: Researching, incubating, and developing innovative solutions to common challenges by taking on innovative projects that would be too risky or resource restrictive for a single CBS provider to take on and where the outcome would be of benefit to all. This can include innovative approaches to financing, waste resource recovery, and technology development.

New entrant support: Supporting the adoption of CBS by new providers by helping to overcome key barriers to entry through standardised knowledge and materials.
