Sustainable Waste Water Botanical Cell planter system:
A Multi-stage contained Water Solution.
This fully-contained system transforms blackwater — originating from toilets and dishwashers only — into clean, treated greywater through three sequential planters or botanical cells. The end result is ‘clean greywater’ that has been treated multiple times. This treated ‘clean greywater’ is ideal for micro-farming as it contains nutrients and minerals to support permaculture and regenerative agriculture to support the people.
Toilets in the housing units flush with treated greywater sourced from sinks, showers, and other greywater systems within the home, significantly reducing the volume of water entering the blackwater treatment planters compared to conventional buildings.
Each planter is carefully lined to prevent leaching, maintaining complete control of the treatment process. The system integrates settling tanks, plant-based filters, and constructed wetlands to remove contaminants, reduce pathogens, and recycling nutrients.
Layers of sand, gravel, and biochar host beneficial microbes, while reeds, cattails, and other plants enhance filtration and nutrient absorption at every stage.
The treated greywater is then distributed to support small-scale micro-farming, fostering sustainability and self-sufficiency within the community.
Water Flow and Volume
With 20 affordable housing units, the estimated daily blackwater volume from toilets and dishwashers is approximately 250 gallons per day. This significantly reduced input volume — compared to conventional systems — is achieved by recycling treated greywater for toilet flushing and limiting blackwater sources to only toilets and dishwashers.
The efficient design ensures optimal performance of the blackwater planters while conserving water resources and supporting sustainable community practices.
