City Water Design

Welcome to OCEAN 

OCEAN is an experiment to use Silkapp to connect : 'big water data' with 'local water rights' AND 'water innovation design' solutions. The goal is for a data journalist / student in urban innovation to fast make a page to show what could be a design solution for water problem A, with people B and innovation C. 


Each minute 42 people enter a city looking for a bed. 

Each minute a family of 4 : "Hello receptionist, do you have a room available?"

This means 15.120 new rooms a day need to be build on the planet, 

in the 366 fastest growing cities between 2006 and 2020.

Below a map on how many NEW beds in India Region need to be installed :

Human Water Right

To respect the Human Drinking Water right for the next 10 years, the 366 world growth cities have to find together every day a DESIGN giving 302.400 liters off fresh water a day, just for the newcomers.  

We collected from 366 cities the data and on average they have to find 1.1 billion liters EXTRA water a year. For Drinking, Cooking, Washing and Flushing. 

We don't talk about food. 

Below the India region where DAILY NEW fresh water needs to be found; 


On the internet you can find huge numbers on what governments need to negotiate for and systems to be planned. We take a different approach, hopefully one day they resonate. 

On purpose we take the daily liters to be extra found, as we cannot wrap our mind around huge numbers to act upon. Our water data is simply based on how many people enter a city and the right the have on water. This is where the water 'design adventure' starts.

Meet Tymus, he is a water design graduate. 

Tymus lives in Nagpur and wakes up every day with the purpose to find a way to get 871 liters off new drinking water in the city. Every day the same routine. Every day he has to come up with a solution which is both fast and affordable. He has to think off a solution and give it to the daily newcomers so they can get every day for as long as they live 871 liters off fresh drinking water just for them. 

Plan like human culture

Our designer in Nagpur doesn't know what to do. How to design a system which will give 871 liters of water every day, at no labor costs. He is thinking about scale, a huge system, which takes care of liters water a year, which he can build one on the edge off the city every year. Than the city can keep up with the demand. 

Design like nature

"No", says a voice in Tymus sleep, "You can design one, you just do not know how yet". There are a zillion water innovations on the planet, you 'just' have to connect the dots to once show it is possible to... 

Catch 8709 liters of rain water and the ability to keep on generating from that 871 liters of Drinking water, 1742 liters Cooking water, 2613 liters of Washing water and 3483 liters of Flushing water. 

"Now... where are those innovations?"

Acknowledgement : 

This article is a test, yet the data is sourced from official data bodies. Many more articles can be made based on the data. 

The amount of water is based on the right to water, not what people in reality have access too, this is done on purpose. We have to design from human rights, if that is under control, than we can design for human plans.

Some other data we connected :

366 fastest growing places on the planet

Population growth from 2006 to 2020

Another one : From the 366, the cities off which will DOUBLE or more in population between 2006 and 2020 : 

Note 1 : As the data is from a reliable source, I think some places also double in population because smaller cities merging into the mother city. 

Note 2 : First seeing this map I thought there is something wrong with the data; no balloons on China... And a zillion on India. However in retrospect, China has birth control, so maybe the cities really are not doubling in size till 2020. 

Last one, 9 European Continent cities growing more than 10% until 2020

( Below percentages are intrinsic to the 9 division, not the growth % )

FOR THE CURIOUS : When you look at the top right corner off a map, you see "EXPLORE". Clicking on it opens the Silk Visualization box. 

- Change the range 49-101 percent to see other growth rates

- pick a different tag to visualize that tag, refine/filter what you like.

- choose a different data template to see a circle diagram or others. 


Global data and local data need to come together. As these maps do not exist, I started to mash some online data from UN etc together.

I am trying out Silkapp for this, as the toolset looks promising! In the future I want to be able to work also with locals to go from Macro maps to micro (even nano) maps collaboration. Useful for neighborhood co-creation development. 

Above a first experiment, water is the focus.
