Water

Floating University Berlin re-envisions an urban water infrastructure that invokes public participation.

How will life change as our relationship to water transforms?

WATER CYCLES

A fundamental paradigm in our research at Floating University is to emulate Mother Earth’s water cycles rather than mimic Corporate Man’s linear sewer pipes. Water will not fall beneath the streets like garbage into landfills. Rather, water flows down the drain, undergoes organic filtration, and flows back out the spout.

Floating University is located in a polluted rainwater basin in urban Berlin. Experimental water systems are constructed at every possible avenue. Its public pedagogy: seminars, workshops, discussions, water filtration systems, water practices and performances, ruminate on our place in the water cycle.

Technology is only part of the answer to our challenges with water.
What’s missing is our relationship with water.

WATER QUALITIES

At Floating University, we have four different types of water on which to experiment: rainwater, basin water, greywater, and blackwater.

— RAINWATER —
Rainwater takes a 6 kilometer skydive. On its descent through the urban atmosphere it absorbs particulate pollution, sulfur dioxide and nitrogen oxides. This tainted rainwater spills off the roofs of the University buildings and funnels through a collection system for reuse.
— BASINWATER —
Basinwater comes from rainwater that lands on the Tempelhof Airport building, airfield and Columbiadamm Road. Currently, this tonic of automobile oil, vulcanized rubber, cigarette chemicals, and trash drains into our large, open air basin where Floating University ‘floats’ and then drops into the canal system and flows to the Spree River.
— GREYWATER —
Greywater is water that becomes “dirty” when it is used. There are various “shades” of greywater. For instance, greywater from our offshore kitchen is laden with grease, fat, and food particles, while greywater from bathroom hand washing is laced with E. coli bacteria.
— BLACKWATER —
Blackwater is the most delicious. Produced by toilet water’s interaction with human waste, blackwater is full of nutrients for plants as well as pathogens. It’s possible to use aerobic decomposition to turn blackwater into fertilizer and anaerobic digestion to create methane gas for cooking.

 

WATER FILTRATION SYSTEM

In 2018, we constructed a water filtration system in the basin. Experimental water systems were constructed at every possible avenue. Water cascades down the laboratory stairs and spirals through a series of biological filters. Then, the filtered water journeys to the University kitchen, bathroom, auditorium, and greenhouse.

The filters are made out of plants, mushrooms, biofilms, sand, activated carbon, molluscs, and bacteria. They are located in a ‘spiral of bathtubs’, a ‘membrane filter’, and a ‘moving bed reactor’.

The ‘spiral of bathtubs’ consists of 9 bathtubs suspended from the ceiling of the Laboratory Tower. A ‘membrane filter’ turns rainwater into drinking water, and provides water for washing dishes in the Spülküche. A ‘moving bed reactor’ filters our dirty dishwashing water into water that is clean enough to irrigate our greenhouse, which grows 35 varieties of tomatoes from across Europe.

This system was deconstructed in 2018, as the project was initially envisioned only for one year. Good news, Floating University continues. The permit to use the land has been extended for 5 years. Stay tuned for upcoming programming in 2020. (An archive of our programming in 2019 and 2018 also exists at the bottom of this page.)

 

WATER IN THE NEW NATURE

Cities as we know them are changing. So too are the climate and planet. Water is a medium that in some ways is the embodiment of change. Floating University is a place where people can come together to explore how we can continue to live in contemporary urban space.
– How will we adapt our practices to the rapidly changing cities and planet to keep water affordable and abundant?
– How might our participation in urban hydrology nudge society toward an ecological balance?
– How might we live, act, and design differently if we have a deeper relationship with water?

How can we be radical dreamers of utopia while keeping our feet on the ground, or in the water, as it may be?

BOOK: WATER LEXICON

The Water Runs Through Us: a lexicon of water practices at Floating University Berlin

This upcoming book documents the story of the water filtration system Floating University during its inaugural year 2018. The manuscript flows through strategies and manuals, oral histories and infrastructures. The collaborative team assembling to create the book includes: Katherine Ball (content collection and writing), Ted Marino (writing), Benoît Verjat and Alexis de Raphelis (visual contributions), Felix Egle (design), Gilly Karjevsky (advising), dpr-barcelona (editing), Adocs (publishing).

WATER RITUALS AT CLIMATE CARE – 2019

In 2019, Floating’s main program was Climate Care, a two-week festival exploring climate change. The water portion of the program “Avulsions of Social Constructions” focused on developing a vision for (1) a future water filtration system at Floating University, and (2) how Floating University could be a place for people to deepen their relationship with water. This included meetings with scientists and a day of water rituals. It was open research: workshop attendees participated in discussions with scientists, water rituals moving water in the body and being moved by water, and discussions to evolve the vision for a future series rituals and water practices at Floating University.

Water Workshop facilitators:
Jose Ordonez of Martin Membranes
Erwin Nolde and Holger Sack of Nolde & Partner Innovativ Wasserkonzept
Paula Malherbe (Ritual: moving water in the body)
Naama Ityel (Ritual: Moved by water – movement exploration practice that reconnects us with our liquid aspect)
Convened by Katherine Ball.
