    Episode 00 - Trailer

    Hi!  It's Kris and Jörg and we're on fire to bring you the Flush to Data Podcast, where wastewater and stormwater meet data science. Our mission is to explore the role of data and models in the world of wastewater science and technology and to bring you experts in the various domains who share their passion and valuable insights.  This podcast is for anybody interested in recent developments on sewers, wastewater treatment plants and water courses. The die-hard wastewater professional, scientist, sewer rat or post-graduate student trying to figure out what we can learn from data on the models we use in our work. We invite experts to discuss recent developments in wastewater modeling, monitoring, data analysis, their favorite bands, and the most probable questions to the answer 42. We are a process engineer and an urban hydrologist with a passion for likelihood functions, prior distributions and music, excited to share the lessons we've learned on our journey in the universe of activated sludge and combined sewer overflows. Follow us on Twitter or talk to us on the next wastewater conference. --- Credits --- In our Trailer and intro we use the beautiful music from the "Obliterator" Amiga game by the incredible David Whittaker https://en.wikipedia.org/wiki/David_Whittaker_(video_game_composer).
