KTH Water Centre

Posted on

attended a workshop at the KTH Water Center (or WaterCentre@KTH) earlier this week. The topic of the workshop was ”Can the Internet of Things make water systems more efficient and sustainable?”

The main starting point was that Stockholm Water know what they put into the pipes and they know what comes out (the charge for the water that we use) but there’s a lot they don’t know about everything in-between, including exactly where the 23% difference between input and output is ”lost”. Leaking pipes? Stolen? Substandard measurements? Something else?

Also, it seems that some losses are acceptable, say about 10% or so. Also, Stockholm Water haven’t really cared about losses since Sweden/Stockholm has had plenty of water and it’s inexpensive too. But if people use more water and Stockholm keeps growing, then there will be limits and building new infrastructure is expesive. So, how would new technologies (sensors, data, APIs, digitalization) help us understand and manage water better? Just the task of detecting and localizing a leak in an underground network is a non-trivial task today and we also raised the question of what exactly a ”leak” is – how big (in liters/second) has to be lost for something to be ”leak” that you would want to fix?

During the workshop, all participants emphasized something our Stockholm Water guest mentioned but that wasn’t really a big part of the invitation to the workshop, namely the fact that we don’t really know a lot about how water is used by households/consumers. Perhaps the (future, expected) pressure on the water system could be decreased by trying to push for ”better” habits concerning water. I found this interesting since I was one of less technically oriented persons but even the other workshop participants recurrently raised this point.

So from having thought that my role in future Water Center activities would be peripheral, it could equally well be argued that methods and ways of thinking from Human-Computer Interaction could be central, for example:

  • Our tradition of working with the interface inbetween technology and ”users”, including our mixed computer science/social science backgrounds, interests and methods. I could for example see me and Elina representing ”user-centered design” perspectives. This goes for Cecilia too who could also bring ”practice theory” into the loop.
  • Mine and Cecilia’s SPOC project emphasizes collecting ”actionable data” from another context (grocery stores) to increase sales of organic produce. The data part (collecting, visualizing existing data or figuring out what new (actionable) data sensors could generate and finding ways to leverage this data to the shop owner, to shop assistantants and to customers seem to be very relevant to Stockholm Water’s problems.
  • When it comes to (big) data and quantified self, Björn’s skills would also seem to be very relevant.

To summarize, I think that several people in our MID4S group as well as other people I know at CESC/ABE school could contribute to Water Center projects.

I also thought the workshop was well organized by the Water Center Director David Nilsson and would gladly take part in another workshop organized by him/them. I would also be interested in participating in a more directed workshop that aimed at brainstorming ideas that would be geared towards a specific project/research grant application.
