Ensure long-term
regulatory compliance
We support engineers, developers, and property owners across South Africa with modular, pre-assembled plants that scale with your needs.
Our Belief
We believe packaged sewage treatment plants can meaningfully improve quality of life and protect the natural environment—especially in:
- Remote or underserved communities
- Water-scarce regions
- Areas with overloaded sewage infrastructure or limited technical capacity
Our Values
We are committed to designing and manufacturing systems that:
- Produce safe, reusable effluent
- Prevent pollution of rivers, streams, and groundwater
- Are easy to operate and maintain
- Deliver sustainable performance across their lifespan
Our Vision
We envision a South Africa where:
- Streets, rivers, and dams are free of sewage
- Treated wastewater helps irrigate green spaces
- Every rural school has a lush, grassed sports field – after all, how else will we find the next Siya Kolisi?
Our Purpose
We help protect life-giving water sources and ecosystems by preventing sewage pollution.
We empower communities with on-site, self-contained, and cost-effective wastewater treatment systems that support responsible wastewater management, recycling, and reuse.
