  1. #Google has been operating under a 16-month non-disclosure agreement ( #NDA ) with #SalemOR concerning a proposed $5 billion #DataCenter.

    The developers hint that it will conserve water—but have not explained how. Could its cooling system use #PFAS “forever chemicals”?

    “Opteon 2P50 is also the first chemical for which industry has asked the Trump EPA to fast-track approval.”

  3. Research - #RainBarrels and Other Household Stormwater Strategies Are Working — For Now.

    May 5, 2026

    Excerpt: " 'When we talk about #CircularEconomy, most people think about #recycling waste and materials. But the concept of circular economy also applies to water. Here we're talking about installing #rainwater #cisterns, reusing water from the sink to flush toilets and using water-efficient appliances. While those may seem like small steps at the individual level, we found that if they are widely adopted, they can have a significant collective impact,' said Fernanda Cruz Rios, PhD, an assistant professor in the College of Engineering, who was a co-author of the research. 'They help reduce demand on the municipal supply, and the energy needed to treat and distribute that water. But what we found was that these strategies offer a real double benefit. In areas like #PhiladelphiaPA and #CamdenME, that are particularly vulnerable due to their proximity to large bodies of water, we were able to see a meaningful reduction in flooding volumes when circular water strategies were adopted.'

    "Despite the ongoing compliance efforts, the cities of Philadelphia and Camden have around 16 billion gallons of combined #sewer overflow, according to reports from their respective water utilities.

    "Over the last two and a half decades, Camden has established a stormwater management plan, including decentralized strategies, an upgrade to #stormwater infrastructure and storm water management modeling. To understand the overall impact of these efforts, in hopes of applying findings to other vulnerable urban areas, the Drexel team created a computer model of stormwater movement using data from Cramer Hill, a neighborhood of Camden in the state’s 'coastal hazard zone' that is highly susceptible to tidal and storm-surge flooding.

    "The researchers structured the model so that it could quantify the distinct effects of outdoor strategies (cisterns and rain barrels) and indoor strategies — efficient fixtures and reusing sink wash water (#greywater) for toilet flushing. It simulated and measured the effect of 16 different combinations of strategies, ranging from rain barrels of different sizes, to varying levels of adoption of water-efficient fixtures and greywater reuse.

    "Each scenario was simulated using precipitation and tidal data from 2014 as a baseline and flooding measurements projected at locations across the neighborhood and at five stormwater outfall areas that contribute to combined sewer overflow discharges into the #DelawareRiver.

    The results show that the combination of retrofitting homes with #WaterEfficientFixtures as well as installing rain barrels and practicing greywater reuse, when adopted by 75% of households, could reduce the volume of combined sewer overflows by as much as 11% and the volume of #floodwaters by up to 13%.

    " 'This finding is an important and encouraging piece of information for municipalities that are facing similar challenges,' Marques said. 'Although broad adoption of these measures can be challenging to achieve, confirmation of its effectiveness may help to make the case.' "

    Interesting read. 🙏🏻 Didn’t realise there were already so many in Australia (“251 data centres already operating across Australia, according to DataCenters.com, with more in the development pipeline”), hope they’re paying top shelf for their electricity (rather than sweetheart deals meaning we pay more for ours - mine had a huge jump this year, imagine it’s the same for others, no sign of the promised 3 free hours daily yet either). 🤔

    On the jobs created question: “… data centres do create jobs, but they are not necessarily going to be supporting a huge, ongoing workforce and, according to the Brookings Institution, data centre advocates "overstate" potential employment benefits.” 🫤

    And on construction jobs they’re competing: “University of Melbourne senior lecturer in construction technology M. Reza Hosseini warns a data centre construction boom could result in a shortage of workers to build much-needed new houses.” Great. Not. ☹️

    “Irrigation plays a critical role in global food production and climate adaptation and exercises profound influence over humanity's water use. Yet despite its critical importance, there is a persistent lack of understanding of fine-scale irrigation patterns across the planet, knowledge which is essential for informing global food security and sustainability targets.

To address this gap, here [they] integrate[d] multi-source Earth observation and environmental datasets and use[d] machine learning to develop a medium-resolution (30 metre) global irrigated area dataset for the 2023/24 growing season. Within existing cropland extent, we leverage a newly compiled set of georeferenced irrigated (N=230,683) and non-irrigated (N=153,194) ground-truth points and integrate seasonal vegetation metrics derived from Landsat 8/9 imagery with agroecological-zone information and hydroclimatic and topographic variables.

The resulting maps were also validated against independent global and national irrigation datasets and statistics, demonstrating broad agreement in the spatial distribution of irrigated areas. This approach is robust and reliable because it is built on a harmonized global ground-truth database, incorporates multiple predictors, and is rigorously validated using independent datasets. All code, ground-truth, and data products are freely and publicly available [link above] and can serve as a robust, scale-neutral, and fully reproducible framework for fine-resolution irrigation mapping.

  9. 1 Toilet Flush = 1 Full Motorhome Shower - videos.trom.tf/w/8GDmQ5yeQPWX2…

    It is astonishing to think that I can take a full shower with less water than it takes to flush a toilet.

    I consume around 4-5L of water for the shower, and to flush it takes 6-8L. One pee, one flush, and you consume more water than it takes me to have a 20 minutes shower.

    In Spain, where I am, people use 128L of water per day, per person. As much as I use in almost 3 weeks.

  15. New research shows the water footprint of AI‑driven data centers is far lower and less risky than many think. While energy use draws headlines, experts say modern cooling tech keeps water consumption modest, even under policy shifts from the Trump era. Dive into the data to see how climate impact is being re‑evaluated. #AI #DataCenters #WaterUse #ClimateImpact

  22. Take a drive through scenic river valleys like the Bitterroot, Flathead, Gallatin or Yellowstone, and you'll find a proliferation of 10-acre ranchettes, often within eyeshot of a municipal boundary.

    The vast majority of those homes are served by wells and septic systems that have no monitoring requirements and almost no state oversight.
