Safa does loads of different stuff for ech2o. Very instrumental in getting The mysterious case of the sinking flamingo out into the world. Lives on a canal boat so really knows the value of short showers!

Kurt is a number crunching pro. He helped ech2o during his school holiday with data analysis and a whole bunch of school work. Cath forgot to quiz Kurt on his water use while he was in the office and now he has gone suspiciously silent over messages…!
