Watch every remote site without a SCADA overhaul
Sentrel pulls flow, level, turbidity, pH, and chlorine off the PLCs and sensors you already run — across lift stations, plants, and unmanned remote sites — with compliance-grade records built in. No integrator, no rip-and-replace.
The monitoring challenge in water & wastewater
Your assets are spread across miles of pipe and dozens of unmanned sites — lift stations, well fields, booster pumps, and outfalls that nobody visits until something overflows. The SCADA that ties them together is often 15-plus years old, locked to one integrator, and expensive to touch. Meanwhile the state expects clean DMRs, SDWA/NPDES reporting, and proof your data wasn't altered. Aging telemetry, thin staff, and rising compliance scrutiny are squeezing the same operators from three sides at once.
- Remote, unmanned sites where a stuck float or dry-running pump becomes a sanitary sewer overflow before anyone knows
- Compliance reporting that means hand-keying logs into spreadsheets and praying the audit goes well
- Aging SCADA that's costly to expand and tied to one vendor's hardware and one integrator's calendar
- Mixed-vendor PLCs and RTUs that were never meant to talk to each other
What you can monitor here
If it already speaks Modbus or OPC-UA, Sentrel reads it. Point a lightweight Node-RED edge connector at the gateway you already have on-site — a Raspberry Pi, Teltonika, or Advantech unit — and it forwards your existing tags over MQTT or HTTPS. No new sensors, no manufacturer cooperation, no touching the control logic that's already running.
- Lift & pump stations: pump run/fault status, motor current, run-hours, cycle counts, wet-well level, high-level float
- Filtration & membranes: differential pressure, filter loading, backwash cycles, turbidity in and out
- Blowers & aeration: discharge pressure, airflow, motor temp, dissolved oxygen
- Dosing & chemical systems: chlorine residual, pH, ORP, metering-pump feed rate, day-tank level
- Tanks & wells: level, flow in/out, overflow detection, draw-down trends
How Sentrel fits — and the outcome
Describe a site in plain English — "alert me if wet-well level holds above 80% for five minutes or chlorine residual drops under 0.2 mg/L" — and Sentrel generates the typed schema and per-reading rules for you. Alerts fire over WebSocket, in-app toast, webhook, and email the moment a reading crosses the line, so a high level or a failed dosing pump reaches the on-call operator instead of the next morning's site visit. Every reading carries a tamper-evident integrity hash and lands in a WORM audit trail, so your monthly report is a filtered export — not a weekend of spreadsheet reconstruction — and it stands up to a 21 CFR Part 11 or state audit. You stand it up in an afternoon, on hardware you own, and watch every site from one screen.
- Plain-English setup: schema and alert rules generated in minutes, not a 6-18 month integration
- Catch SSOs, dry-running pumps, and out-of-spec residuals before they become violations
- Compliance reports as a one-click export from tamper-evident, audit-ready records
- AI-editable live dashboards and SCADA views per site, plant, or operator
- White-label and multi-tenant: run districts, contract-operated plants, or your whole utility from one platform
Water Treatment, answered.
No. Sentrel reads the equipment you already run over Modbus and OPC-UA using a lightweight Node-RED edge connector on a gateway you own — a Raspberry Pi, Teltonika, or Advantech unit. It forwards your existing tags over MQTT or HTTPS without touching your control logic. There's no proprietary sensor, no manufacturer cooperation, and no rip-and-replace.
Every reading is stored with a tamper-evident integrity hash in a WORM audit trail, so your data is provably unaltered for SDWA, NPDES/DMR, and 21 CFR Part 11 review. Monthly and exception reports are a filtered export rather than hand-keyed spreadsheets, with RBAC and module permissions controlling who can see and change what.
Yes — that's the core use case. Sentrel watches wet-well level, pump run/fault status, flow, pressure, and chemical residuals at sites nobody visits daily, and fires real-time alerts over WebSocket, in-app toast, webhook, and email when a reading crosses your threshold. You define those thresholds in plain English and Sentrel generates the rules for you.
Stop integrating. Start monitoring.
Describe what you want to watch, connect the gateway you already own, and be live this afternoon — no integrator, no proprietary hardware, no six-month project.
