Last week, our community engaged in rich discussions about innovative environmental engineering solutions and their impacts on ecosystems. A standout topic was the integration of SCADA systems with traditional rainwater harvesting methods, sparking debates about technology’s role in sustainable water management. Members also exchanged ideas on designing stormwater basins that support wildlife, highlighting a growing interest in eco-friendly infrastructure. Moreover, conversations about the balance between urban development and wildlife conservation revealed the complexity of modern environmental challenges.
This Week’s Hot Topics
My rain barrel thinks it’s SCADA
This conversation dives into the unexpected intersection of rainwater collection systems with SCADA technology, offering a glimpse into the future of smart water management.
Designing stormwater basins for wildlife
A look at how engineers are creating stormwater basins that not only manage water but also serve as habitats for local wildlife, blending infrastructure with ecology.
Our foxes need room to hunt
This thread explores the challenges of urban expansion on natural habitats, focusing on how to ensure wildlife, like foxes, aren’t displaced by city growth.
Reliable UV254/TOC sensors for coagulant control
Here, professionals discuss the latest in UV254 and TOC sensor technologies for improved coagulant control in water treatment processes.
First net positive wastewater plant
Celebrating a milestone, this thread covers the world’s first net positive wastewater treatment plant, highlighting its design and sustainability achievements.
We tied our SCADA to a $60 RS‑485 level sensor and a motorized valve on the barrels, then pre‑drain about 20% when the next 6 hours show >50% rain on https://api.weather.gov. , forecasts are noisy, so hysteresis + a 10‑minute minimum run stopped pump short‑cycling. Small caveat: add a local fallback so the valve fails safe if power or the SCADA link dies, especially if it feeds a stormwater basin.
I’ve had better luck triggering SCADA pre‑drain off forecast QPF totals, not probability — if the next 6 hours show >10 mm, we dump about 15% per barrel. , POP burned me last month and we ditched 25% for a drizzle. I pull QPF from https://api.weather.gov/gridpoints/ and keep a tipping‑bucket as a fallback when the API lags; @Renee, it also saved us from over‑draining before a cold snap.
Added a 30-min radar nowcast check in SCADA (via Node-RED) before any drawdown, which killed most false releases from twitchy forecasts… I keep a hard ‘reserve’ of 25% with a $12 float failsafe for when api.weather.gov hiccups. If you’re tuning QPF like @zhenya56, add a small hysteresis (about 3%) so the valve doesn’t chatter on update swings.
On our last pilot, the “SCADA meets rain barrels” bit worked better after we added a physical high-float and a 5-minute debounce on the level feed; otherwise wind-driven slosh kept triggering drains, . We also put a freeze lockout at 2°C and a cheap $18 Wi-Fi relay for manual override, but if you try this be ready to clean the valve strainer monthly or it’ll stick half-open.
