Water tech, with teeth and numbers.
(don't) Waste Water treats pipes, treatment plants, wastewater, and microbes as the machinery underneath politics and markets. It is analytical, blunt, and unusually alive to the money story hiding inside infrastructure decisions.

(don't) Waste Water covers water technology as the hidden operating system of modern life. It is not gentle trade-magazine audio. The show moves quickly, piles up context, and keeps asking why everyone acts surprised when old pipes, scarce water, regulatory loopholes, or geopolitical supply chains finally become expensive. Its natural habitat is the place where engineering meets capital. AI data centers are not treated as a simple consumption panic; the argument shifts toward discharge, cooling choices, hyperscaler risk, and the possibility that major tech companies may want to own more of the water chain. A French football club's reuse system becomes more than a sustainability project. It becomes a hedge against drought restrictions, activist pressure, brand exposure, and the economic collapse of French football's broadcast model. Municipal pipe failure gets the same treatment. Detroit floods, Potomac sewage, replacement cycles, emergency repair costs, and tariff math are drawn into one larger question: who pays for infrastructure that was allowed to age in public. The show also likes the unexpected upside case. Wastewater biogas is framed against Europe's gas vulnerability. Algae treatment is framed through Pierre Côté's record as an inventor. Real-time microbial monitoring with Lorenzo Falsarano becomes a practical argument about why water safety still depends on slow tools in a world that wants live data. The interview episodes keep the same pressure. Guests are not just asked what their companies do; they are pushed into the adoption problem, the funding path, the utility buyer, and the gap between promising technology and actual deployment. That gives the show a distinctive texture: technical enough for sector insiders, but argumentative enough for investors, founders, and infrastructure-curious listeners who want the stakes made visible. It can be irreverent, and it clearly enjoys a sharp aside. Still, the core promise is serious. Water is where climate, industry, law, public health, and money keep colliding, and this show follows the collision instead of smoothing it over.
Made for: Built for water-sector operators, water-tech founders, infrastructure investors, utility watchers, and curious generalists who can handle technical detail at speed. It especially suits listeners who want market logic alongside engineering reality.
What sets it apart: The show turns water stories into strategic arguments, connecting treatment technology, regulation, capital flows, brand risk, and geopolitics in the same breath. It is livelier and more opinionated than a conventional industry interview show.

Short reviews from the PlayNext desk, based on the episodes we processed.
A 49-to-1 water comparison opens into a sharper look at what data centers leave behind.
AI's water footprint looks different once the episode puts American turf grass beside U.S. data centers: roughly 12 billion cubic meters against about 250 million.
Aging pipes turn emergency repairs into a $2.6 billion annual bill.
The episode frames underfunded U.S. water infrastructure as a household-cost problem, turning aging pipes into a chain of visible failures and unavoidable bills.
A grounded case for seeing sewage infrastructure as a limited but real hedge against Europe's gas exposure.
Europe's gas vulnerability gets recast through the less glamorous economics of wastewater treatment, as the episode connects damage at Ras Laffan to a broader search for energy resilience.
Orb's bet is that light can spot microbial change before conventional water testing catches up.
Water testing becomes a race against evidence that can disappear. Bacteriological issues are framed as a major share of water quality standards failures, and the one category not monitored in real time.
Perrier's filtration crisis becomes a clear story about regulation, branding, and the cultural power of mineral water.
Perrier's crisis lands as a clash between contaminated wells, illegal filtration, and the cultural authority mineral water has built around itself. The episode follows the destruction of 2 million bottles after E.
Frontier technology, seen at civilizational scale.
Consumer brand strategy without the gloss.
Southern startups, capital, and conviction.
Loose, opinionated hallway talk about AI products and craft.
A venture capital firm discusses their journey, including failures and successes, in building funds and delivering returns to investors.
Antoine Walter interviews Terry Paul about Botanical Water Technologies, which harvests water from fruit and vegetable processing to help companies like Microsoft achieve net zero water goals.
In 2024-2025, Nestlé's Perrier faced crises with millions of bottles destroyed due to E.
The episode analyzes why companies like Georg Fischer are now betting big on water technology, reversing a decade-old trend of divesting water divisions.
In (don't) Waste Water!
A look at how French football clubs are cutting costs amid a financial crisis, contrasting with Stade Rennais's investment in a water reuse system funded by its luxury parent company.
The episode opens with the February 2025 southwest Detroit rupture of a 54-inch steel water main and a January 2026 Potomac River sewer collapse to show how often aging infrastructure fails.
After the Ras Laffan damage and the Qatar gas shock, the narrator says TTF hit 60 euros per megawatt hour while European gas storage sat below 30%.
The episode traces Pierre Côté’s career from Xenon Environmental’s Z-Wid membrane bioreactor to the MABR technology developed with GE Water, including Xenon’s $689 million acquisition.
Antoine Valterre frames the episode around bacteriological failures, saying they are the top five of the top ten water-quality standards failures and the only major category not monitored in real time.
A venture capital firm discusses their journey from failure to success in cracking the water code, focusing on fund returns and LP relationships.
Perrier faces a crisis after illegal water treatments are exposed, leading to a 60-day compliance deadline they cannot meet.
