ERADICATING PIT TOILET - 11 000 Schools
Amanzi Water Systems — School Sanitation & Food Garden Solutions
01
Reimagining School Sanitation in South Africa
Amanzi Water Systems is transforming the way South Africa approaches school sanitation. The real challenge facing schools is not simply the lack of toilets — it is the collapse of municipal sewer infrastructure and the inability of centralized systems to keep up with growing demand. Amanzi provides decentralized sanitation infrastructure that allows schools to operate independently from overloaded municipal sewer networks. By combining wastewater treatment, water reuse, and food production, Amanzi turns sanitation from a recurring cost into a sustainable community asset.

From Wastewater to Food Security
The Amanzi model was successfully demonstrated at Ennis Thabong School, where a failing sanitation system was transformed into a long-term solution delivering clean sanitation, irrigation water, and a productive food garden. For more than 10 years, the school has used treated wastewater to irrigate spinach gardens that help support learners and the local community. This real-world success proves that sanitation infrastructure can also become food production infrastructure. Amanzi changes the national conversation from “sanitation as a cost” to “sanitation as economic opportunity.”

Decentralized Infrastructure for Water Independence
Traditional sanitation systems rely heavily on centralized municipal infrastructure that is expensive, slow to expand, and often unreliable. Amanzi provides decentralized wastewater recovery systems that treat sewage locally, eliminate septic trucking costs, and reduce dependency on failing municipal networks. The systems generate irrigation water for food gardens while improving hygiene, reducing health risks, and creating more resilient school infrastructure. Amanzi does not simply install sewage plants — the company builds Water Independence Systems designed for long-term sustainability and local economic impact.

Scientific Validation and Strategic Partnerships
The technology platform developed by Amanzi Water Systems is supported through scientific collaboration with the Council for Scientific and Industrial Research. This validation provides technical credibility and strengthens institutional partnerships with education departments, municipalities, agricultural organizations, development finance institutions, and ESG investment partners. Amanzi’s integrated approach addresses multiple national priorities simultaneously, including sanitation, water security, food production, climate resilience, and community development.
02
A National Infrastructure Opportunity
South Africa has approximately 25,000 schools, many of which still rely on pit toilets, septic systems, or expensive temporary sanitation services. Amanzi aims to create a scalable national sanitation infrastructure model capable of serving hundreds of schools across the country. The company’s target is to establish systems in at least 500 schools, creating recurring infrastructure revenue while delivering measurable social impact. By enabling schools to expand sanitation capacity without waiting for costly municipal sewer upgrades, Amanzi positions itself as a strategic national infrastructure partner rather than a conventional contractor or supplier.
03
Building the Future of Water Security
Water scarcity will define the next generation of infrastructure development, and companies that control water treatment and reuse systems will play a critical role in the future economy. Amanzi Water Systems is building a new model for decentralized sanitation and water reuse across South Africa. Through wastewater treatment, water recycling, and food production, Amanzi creates systems that improve sanitation, strengthen food security, generate community income, and reduce pressure on failing municipal infrastructure. The vision is simple but powerful: turning school sanitation into clean water, sustainable agriculture, and long-term community resilience.
“For more than 10 years, the Amanzi system at Ennis Thabong School has demonstrated how decentralized sanitation can deliver far more than clean toilets. The project eliminated septic truck dependency, improved sanitation reliability, and created a productive food garden irrigated with treated wastewater. This long-term success continues to support food security, water reuse, and sustainable infrastructure development for the school community. Supported by scientific collaboration with the Council for Scientific and Industrial Research (CSIR), Amanzi Water Systems is proving that school sanitation can become a foundation for water independence, food production, and community resilience.”
