Evapo-Transpiration Toilets (ETT)
At the forefront of our sustainability initiatives is the innovative Evapo-Transpiration Toilet system. This is a closed-loop, zero-discharge system that treats wastewater onsite, conserves water, and prevents pollution of local water bodies.
How It Works
Collection
Wastewater from toilets is collected in a sealed, underground tank.
Anaerobic Digestion
In the tank, anaerobic bacteria break down the solid waste, turning it into nutrient-rich sludge.
Natural Filtration
The liquid effluent then flows through a constructed wetland, a bed of specific plants and gravel that naturally filter and purify the water.
Evapo-transpiration
The plants in the wetland absorb the nutrient-rich water, using it for their growth and releasing clean water vapor into the atmosphere through transpiration.
Key Benefits
Zero Discharge
No wastewater is released into the environment, preventing contamination of groundwater and rivers.
Water Conservation
The system is completely water-efficient, saving thousands of liters of fresh water.
Nutrient Recycling
The system creates a mini-ecosystem where nutrients are recycled, supporting a lush plantation of bananas and other plants.
Low Maintenance
The ETT is a self-sustaining system that requires minimal energy and maintenance.
Our Impact in Numbers
Over 1 million liters of water saved annually
100% of our blackwater is recycled onsite
Supports a thriving plantation of over 100 banana trees
