Global Sanitation Challenge
The majority of the world's population uses onsite sanitation systems like pit latrines and septic tanks. These systems require emptying when full, but many households lack access to proper emptying services due to high costs or unsafe standards.
The Innovation
Since 2021, Opero and Practica Foundation have collaborated to test and commercialize the Pupu Pump – a revolutionary mobile pit emptying technology. The technology has been successfully tested with Gasia Poa, a waste management enterprise in Kisumu, Kenya.
Specialized Design
Developed specifically for emptying where traditional exhausters cannot reach, using innovative Push + Pull technology.
High Efficiency
Can pump 3000L in 20-30 minutes with the ability to reach up to 70m distance to storage tanks.
Safety Focus
Minimizes operator exposure to faecal sludge and prevents environmental contamination through proper waste containment.
System Components
Pumping Unit
Advanced pumping mechanism with small compressor and reservoir system.
Valve System
Automatic duckbill non-return valve with manual suction/pressure control.
Storage System
Compatible with tanks of any capacity for flexible deployment.
Through the test done with Ghasia Poa as service providers, they have been able to move from manual emptying methods to a more professional service enabling them to:
- Decrease the emptying time and cost for service provision, allowing them to target more customers (40,000+ customers served to date).
- Increase the profitability of the enterprise, leading to an increase in job opportunities.
- Increase the safety of pit latrine emptying processes (no longer a manual process), improving work conditions.
- Increase the legitimacy of pit latrine emptying service provision, making it an appealing opportunity for youth and women.
