Water Systems Bench

What it does

Water Systems Bench brings pumps, pipes, wells, storage, rainwater, irrigation, and water treatment into one connected planning workflow. It includes 32 interactive tools, 14 practical guides, and 8 technical references, with support for SI and US customary units. It is built for preliminary sizing, comparison, troubleshooting, and practical field decision support.

Practical pump, storage, monitoring, irrigation, reuse, industrial and treatment tools for connected water-system planning.

Practical tools, field-oriented guides and technical references for pumps, wells, storage, monitoring, irrigation, reuse, industrial rinse water and treatment—from source testing to documented use. Built for global use with SI-first calculations and common US customary units. Results support preliminary planning; they are not formal design, sampling authorization, potable-safety or regulatory approval. Water-system decisions depend on each other. Storage changes pump duty. Pipe size changes friction. Pressure requirements change power. Treatment and end use shape the whole path. Build flow, TDH, loss, duty point, power and suction checks. Connect source yield, pumping, pressure, stored…from watersystemsbench.com

  Wetlands – a lightweight Python library for managing Conda environments2025 · arthursw.github.io · ▲30

  When building a plugin system for an application, avoiding dependency conflicts is critical. To address this, I created Wetlands – a lightweight Conda environment manager. Wetlands not only simplifies the creation of isolated Conda environments with specific dependencies, but also allows you to run arbitrary Python code within those environments and retrieve the results. It uses the multiprocessing.connection and pickle modules for inter-process communication. Additionally, one can easily use shared memory between the environments, making data exchange more efficient. Docs:…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
