I'm building epanet-js[0], a local-first web application for simulating water network. The goal is to replace clunky, expensive enterprise desktop tools (which often charge $10k+ f…

The GIS system is generally the base for a hydraulic model. You use that data to build a connected graph structure that the hydraulic engine, EPANET, uses to run calculations to fi…

Currently the two largest vendors of hydraulic modelling software are Autodesk and Bentley. Both have taken the EPANET engine and created private forks in the 90s/2000s and never c…

One of the two authors of epanet-js here - you can check out the source code for the app here: https://github.com/epanet-js/epanet-js

We created this from a fork of Placemark[0] to give water utilities an alternative choice to the big players, Autodesk and Bentley. The majority of commercial modeling software use…

I’m building a local-first web app, and SQLite works well for my case since a single project can be contained in one database file, just like users are used to with existing deskto…

At the start up I work at [0], we use an open source library I developed to run hydraulic models of water networks in JavaScript [1]. A hydraulic model may be between 1-10MB and th…

For those that haven't seen them, the two Technology Connection videos on dishwashers are must watch 1 - https://www.youtube.com/watch?v=_rBO8neWw04 2 - https://www.youtube.com/wat…

I've found decent success sharing short product features videos, always less than 15 seconds, on LinkedIn. Making the videos run much faster than normal, at least 1.5x and up to 3x…

I'm a civil engineer and I wrote an open source library that compiled a C library to javascript for my own personal projects - epanet-js [1] A water utility in Spain spun off a sta…

I created a handful of application around water engineering/modelling [1], plus an open source library to run the simulations in javascript [2]. A water utility in Spain spun off a…

I work as a water engineer, specializing in building hydraulic models so water utilities can simulate their network. A big part of that is calibrating them which can be time consum…

Many thanks to tsholmes for finding a solution and sharing it with me. He has requested the full amount be donated to Nine Lives Foundation, proof of donation can be seen here: htt…

I've had confirmation from a couple of sources now that this is indeed a SQLite file, or at least a derivative of it, with some key information missing. If you email me how you kno…

SEEKING FREELANCER | $2,000USD bounty - Work complete, and bounty donation at users request I'm working on an open-source library in a niche civil engineering field. I have a propr…

EPANET ( https://github.com/OpenWaterAnalytics/EPANET & https://www.epa.gov/water-research/epanet ) Chances are the water network that's connect to your home was modelled using thi…

I think the vast majority of this thread agree with you that what we saw in the article was incredibly dangerous to the employee. In my example these sites are unmanned 99% of the …

When I worked at a water utility we would occasionally have people breaking into our remote sites like water towers either to vandalise them or climb the assets for the view. When …

A webapp to help me calibrate hydraulic models of water networks. The original concept was in excel and VBA. I ended up pulling out the engine as a separate open source library whi…

I'm a Civil Engineer who spends roughly half my time programming. While I'm not the best engineer or programmer out there, blending both skills has been a massive advantage for my …
