Our worldwide habitats

Take a look at the communities that welcomed us.

Twelve of us are already at work. From our home ground in the Netherlands and Belgium to five of us cleaning water in Salfit on the West Bank — every herd member is looked after by the community around it, and together we are getting ready to move into many more neighbourhoods in the year ahead.

  • Silvolde, the Netherlands — 1 BluElephant
  • Salfit, West Bank — 5 BluElephants
  • Almelo, the Netherlands — 1 BluElephant
  • Denekamp, the Netherlands — 2 BluElephants
  • Enschede, the Netherlands — 1 BluElephant
  • Herentals, Belgium — 2 BluElephants

Technical info

Inside us live millions of bacteria — an activated sludge that does the heavy lifting. After they have done their work, ultrafiltration separates the clean water from the sludge, and UV disinfection adds a second barrier against pathogens. What comes out can flush toilets, water crops or flow safely into surface water. Even the leftover sludge keeps going: it makes good compost.

Capacity

One home or apartment block: the household water of 50 to 150 people, every day.

Treatment steps

Activated sludge → ultrafiltration → UV disinfection.

What we remove

Pathogens, plus nitrogen and phosphate down to an optimal level.

Natural polishing

A wetland or hydroponic bed planted with halophytes gives the water a last natural pass.

Where the water goes

Crop irrigation, toilet flushing, surface water — or back into the aquifer, directly or by infiltration through the wetland.

Drinking water

An optional point-of-entry unit with activated carbon and UV feeds drinking water back to the residence through a ½” pipe.

Energy

Low consumption, with solar panels on us and on the ultrafiltration unit.

Connections

A buffer tank with shredding pump feeds us through a 2″ PP pipe; our shell is made of recycled plastics.

Design for life

Designing for life means creating the conditions in which life can thrive — all life, including life that looks different, lives far away or comes after us. Dutch designer Ruurd Priester put that idea at the heart of the book Ontwerpen voor leven (Designing for life, 2022). It is at the heart of us too: clean water is where life starts, so we give household waste water a new life right where it was used.

Priester borrows two design principles from Doughnut Economics. Regenerative: leave take-make-waste behind and work with the cycles of the living world. So we run on little energy and our own solar panels, our shell is made of recycled plastics, and the water we clean goes back to crops, toilets, surface water or the aquifer. Even our leftover sludge becomes compost.

Distributive: share rather than concentrate, spread rather than scale up. We are small enough for one home or an apartment block, simple enough for the community around us to operate, and mobile enough to move where we are needed — no central plant required. One elephant at a time, looked after by the people who welcomed us. And, as Priester asks of every designer, we were made by going deep and doing it together: public and private partners, side by side.
