Guided Tour - Roof Water Farm Berlin

Foto: Marc Brinkmeier © ROOF WATER-FARM

The ROOF WATER-FARM demonstrates paths towards innovative city water management and urban food production. Potentials and risks of redesigning across sectors of infrastructure will be explored and communicated.

The project investigates opportunities for building-integrated water treatment systems to irrigate and fertilize roof-top greenhouses. Technologies for water treatment and aquaponics (plant and fish cultivation) will be examined at a demonstration and test site in Berlin-Kreuzberg. The research focuses on a hygienically safe usage of rainwater, greywater and blackwater as both a strategy for city water management and a potential for urban food production.

The transferability of the ROOF WATER-FARM concepts into the urban realm will be examined based on preliminary findings. Structural variants of greenhouse plant and fish production in greenhouses will be projected for the scale of a building unit, and upscaled for urban spaces at large.

ROOF WATER-FARM explores ways to disseminate these technologies in the urban realm by:

  • developing and communicating the technical concepts of ROOF WATER-FARM concepts as typological building design studies (profiles, prototypes, building parameters and infrastructure)
    performing cost-benefit analyses and life-cycle assessments (sample calculations, model worksheets)
  • identifying the socio-cultural impacts and effects of urban water management and design on selected residential districts in Berlin (exemplary scenarios, case studies)
  • analysing potentials and risks of integrating and diffusing these urban water management concepts across sectors (multicriteria analysis of innovation potentials and risks)
    analysing drivers and constraints in the innovation arena and developing strategic approaches for the diffusion of the ROOF WATER-FARM concepts (constellation analysis)
  • determining recommendations of action for the different actors and
  • developing communication and training media about decentralised water treatment and urban food production.

We will do a tour to the Roof Water Farm Berlin to learn about water-farming strategies for the future city including:

  • how to filter grey waters from an apartment block
  • to transform black water from toilets into an urban fertilizer called „goldwater"
  • to use the filtered water to feed an aquaponics system and the urban fertilizer for hydroponic plant production
  • how the Roof Water-Farm approach could transform buildings, neighborhoods and daily life in the city
  • how this concept could be transferred to the Agora Circular Economy Lab

I have been there for a BMBF Conference. I was really interesting for all aspects:

  • really technical results for waste water and rainwater treatment
  • aquaponie farming is also very worthwhile for comparing different growing technics: process water / waste water
  • social inclusion with the neighbourhood

I would definitely recommend it !

Nice! Who can participate? When do you need to know the latest? @simonlee

everyone of course:)
no deadline yet, but would be nice to know in advance.

Thanks for giving the Roof Water Farm a posibility to get part of the OSCEdays @simonlee. I think this can be seen as a perfect example of collaboration between innovative SME (Mr. Nolde with Nolde und Partner) and Science (TU Berlin) in the water sector of Berlin. We as the business development agency of Berlin (Berlin Partner für Wirtschaft und Technologie) appreciate those very good examples of networking and knowledge Transfer and thus are very happy to support this lighthouse project on the OSCEdays together with AQUANET Berlin-Brandenburg and CRCLR.


due to growing demand and limited places, pls register here if you want to participate. you can also do it during the event.

Sounds like you should connect with the Helsinki pee-ponics project to recycle urine into food. I would love to know what you think about it:
I’m working on the circular sanitation challenge and would love to plan a trial for next year’s OSCEdays Berlin.

Hi Maike, thank you so much for your input! I think this is what is very special about the world wide OSCEdays. Nice. I will definately forward that to Mr. Nolde and Ms. Bürgow working on the Roof Water Farm project. By the way, Mr. Nolde is one of the nominees of the AQUA AWARD which is awarded the first time in the frame of the AQUABALL by AQUANET and Berlin Partner this Saturday!
