As we announced earlier we’re going to make more designs before getting to work. We’ve been doing this for years for our IT infrastructure but with the new business we’ll also be doing this for the structures we plan to build.

Water is an important resource. In the Netherlands we have sufficient drinking water from the tap, however there are costs involved, both financially as ecological. The Urban Aquaponics Greenhouse we’re planning to build will require a lot of water. With high temperatures in a greenhouse, particularly in the summer, water from the fishtanks will quickly evaporate.

With a rainwater recycling system we want to assure a sustainable source of fresh water in order to be able to replenish the evaporated water without an impact on the environment and our wallets. The excess rainwater will be used as a secondary water source for our household (an average family’s water bill consists for approximately 50% of toilet water which can easily be taken from rainwater)


This design is intended for people who want to do a comparable project but have no idea where to start. This design is provided free of charge.

Inputs and Outputs

Before describing the interfaces of the rainwater system we would first like to write a few words about the form in which we will publish our designs. In the IT world it’s an architectural business to connect designs together in a so called ‘IT landschape’. The IT landscape gives a clear and insightfull map of several designs interacting with each other, each having their own inputs and outputs.

These inputs and outputs can be interfacing together, which makes the coherency between the systems clear, Through optimizing the interfaces, extra value can be created.

For every design we’ll publish we’ll list the inputs and outputs of each system and indicate which interfaces exist between the designs.
