Currently in its 10th Season, the "(don't) Waste Water" podcast has already welcomed around 250 guests from Water Majors (SUEZ, Veolia, Jacobs, Xylem, Kemira, Evoqua, Aquatech, SKion Water...), Scale-Ups (Cambrian Innovation, Epic Cleantec, Gradiant, Liqtech, 374Water, Gingko Bioworks...), Start-Ups (Puraffinity, KETOS, 120Water, ZwitterCo, Membrion, Source...), Universities (Berkeley, the Columbia Water Center), Investment Funds (Sciens Water, Mazarine, Burnt Island Ventures...), Business Accelerators (Imagine H2O, Elemental...), Book Authors (Seth Siegel, David Sedlak, David Lloyd Owen...) or Market Intelligence Companies (BlueTech Research, Global Water Intelligence, World Bank, OECD, Isle Utilities...). Or simply water legends like Gary White, Mina Guli or Andrew Benedek!

On the "(don't) Waste Water" podcast, I strive to make the Water Industry easy to understand for everyone, starting with water professionals, executives, and investors. Hence, he opens the microphone to seasoned, inspirational water experts to discuss their field of excellence.

No one can claim an all-around in-depth understanding of a matter as complex as Water. But piece by piece, you can rebuild the puzzle. With curiosity, patience, and passion, Antoine Walter explores topics such as Advanced Treatment Technologies, Water-Energy Nexus (Hydrogen, Lithium...), PFAS removal, Nature-Based Solutions, Wastewater Reuse, Distributed Water Treatments, Water Finance, and Water Entrepreneurship.

I actually firmly believe that regular listeners of the "(don't) Waste Water" podcast may, in the end, claim a "Water MBA!"

A particular field of interest is how innovation forms, grows and gets widely adopted in a complex and conservative field like the Water Industry. This may be one of the keys to achieving the United Nations Sustainable Development Goal n°6 - #SDG6.

Oh, and in short, about me: I'm a water engineer turned avid student of the water business, market, finance, and tech. I'm married, a happy father of three, and I'm French (nobody's perfect 😅).

Water Industry Trends 2025: What 153'482 LinkedIn Ads Reveal
Wanna see the Future of the Water Industry? Listen to this! More #water insights? Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ A big thanks to my sponsor, SimpleLab! https://gosimplelab.com/ I know the future - so let me share it! Indeed, yes, I did it again: I drowned myself in 153'482 LinkedIn ads for the keywords "Water" and "Wastewater" from Q2 to Q3 2024 (using a “slightly homemade” scraping approach - please forgive me, LinkedIn!). I did so, looking for the signals companies believe will make them money in 2025 - that's how I know the future. Why ads, you ask? Well, for a simple reason: businesses rarely burn ad budgets on dead-ends. So, if they’re paying to talk about it, they must see an ROI!

Water Industry Trends 2025: What 153'482 LinkedIn Ads Reveal

Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ A big thanks to my sponsor, SimpleLab! https://gosimplelab.com/ I know the future - so let me share it! Indeed, yes, I did it again: I drowned myself in 153'482 LinkedIn ads for the keywords "Water" and "Wastewater" from Q2 to Q3 2024 (using a “slightly homemade” scraping approach - please forgive me, LinkedIn!). I did so, looking for the signals companies believe will make them money in 2025 - that's how I know the future. Why ads, you ask? Well, for a simple reason: businesses rarely burn ad budgets on dead-ends. So, if they’re paying to talk about it, they must see an ROI!
