If you get past the eck factor this makes a lot of sense for all sort of things. Now its not really a robot, its more just an IoT Sensor that measures various components of sewage and really if you can measure something, why not do it.
That’s an excellent source of data I hadn’t considered. To me, the really cool part of this is how it can scale. You could start with one node at the sewer treatment plant, then one node at each main trunk, then eventually at every street or every house as the economies change. Thanks!
