We’ve seen how easily water can be assumed “safe” without anyone really knowing. With @saafwater, we’re building a way to change that.
Your water purifier isn’t telling you the truth. I learned that the hard way, when my mom got sick from “clean” water. So we built something that can actually see what’s inside your water 👇

Couldn’t have said it better. Every call, visit, and test taught us lessons that are now shaping #ProjectMiramar and the latest developments at @saafwater. Our first deals showed us that sales is not just about technology. It is also about credibility and trust. Building in…
How we 20-year-olds figured out this offline market with no prior experience in B2B sales. We started out thinking the tech would be the tough part. Boy, we were wrong, it was all about getting people to believe in us. (LONG POST AHEAD) Picture this: four young guys in our…
Appreciate the mention @RuntimeBRT and @caleb_friesen2! To fulfil #ProjectMiramar, our team has been on ground every day, talking to users, testing systems, and iterating based on real field feedback. We’ve already brought BOD & COD down by over 93%, maintained stable pH, and…
🇮🇳 Indian Tech Update ‣ Oct 19 2025 🚨 Goa-based deeptech startup @saafwater is planning to deliver Project Miramar, a full-stack upgrade to their water-quality intelligence platform, in less than a month. Saafwater builds hardware that monitors water safety in real time.
Ever wondered how cities or industries track water quality across entire systems? 🌊 We’re beta testing Scenes at @saafwater, which lets you group multiple Saafwater units into one unified dashboard. Designed for scale: utilities, industries, treatment plant OEMs and O&M…
Utilities can choose ritual or resilience. Citizens can choose silence or transparency. Our work is a bet on the second.
As part of @enter_delta @_TheResidency, we’ve been documenting in public what it’s like building hardware @saafwater for one of the slowest — but most meaningful — industries on earth.. Water. Weekend’s here, and with Diwali right around the corner, most of our client offices…
Thanks, @Runtime @caleb_friesen2, for the shoutout! It’s inspiring to be featured alongside fellow Indian tech innovators. Your support keeps us pushing the boundaries, from monitoring to true water intelligence, helping everyone see, understand, and act on water quality…
Here's everything that happened in Indian tech in the last 24 hours: 1. @MacawberBeekay built India's first waste-to-coal plant. 2. @ekamobility raised ₹500Cr to build EV buses. 3. @saafwater was accepted into Delta Chapter II. 🚨 Follow Runtime for daily Indian tech news.

Do we sell purifiers? Do we supply water? Or do we sell bottled water? Here’s what we really do → @saafwater
BOD & COD down by 93%. pH steady. Discharge within central pollution control board limits. All from one hospital’s Sewage Treatment Plant — just days after installing #SaafwaterOCEMS.
Pure execution days hit different. Nothing fancy, just progress. #ProjectMiramar @saafwater
Today @saafwater was pure execution 👇 🔹 Closed 2 more sales on our early representation product -demand keeps growing even before we build #ProjectMiramar 🔹 Fixed PCB errors + ordered bulk (arriving next week to keep sales running) 🔹 Designed a new case for our early models…

The most resilient utilities aren't the ones with the biggest plants. They're the ones with the most honest data. And honesty comes from real-time monitoring.
Pragmatism > Perfection. A lesson from our latest hardware sprint @Saafwater Our 1st attempt at a display was a custom 7" ESP32-S3+LVGL. It was bulky and low-res. After finding RasPi displays too costly, we pivoted to a simple Android tab A fast, pragmatic move. #buildinpublic
What good is "progress" if the very infrastructure delivering it is rotting beneath us? Real progress is antifragile water systems — where safety compounds daily.
Testing valve interfaces made from different 3D-printed materials: 1️⃣ SS316L (Binder Jet) 2️⃣ Nylon (SLS) 3️⃣ Nylon (MJF) 4️⃣ High-strength resin (SLA) After just 1 day, the SLA part failed — the gear teeth wore out!
21 days. Build mode on. The next 3 weeks are all about #ProjectMiramar with @enter_delta x @_TheResidency.
