USED WATER SENTINEL SYSTEM, IoT based Centralized Monitoring for Entire Used Water Treatment Plants, TTRO and TTUF in Chennai

IoT gateways & communication integration (SDC ↔ SCADA/HMI) This item covers the supply, installation, configuration, and commissioning of Industrial IoT Gateway Panels for all 20 STPs. Each panel establishes secure, real-time communication between the local PLC/SCADA/HMI and the State Data Centre (SDC) using multi protocol conversion (MODBUS RTU/TCP → MQTT/OPC UA/HTTPS). Scope includes a) STP operations requires hardware-focused instrumentation upgrades: vibration accelerometers, RTD temperature sensors (bearing/ DE/ NDE/ winding), and power analyser for predictive maintenance to detect imbalances/cavitation early, reducing downtime by 30-50%; differential pressure transmitters, electromagnetic flow meters, and ultrasonic / radar level sensors across aeration tanks, clarifiers, and recycle lines for real-time process optimization (DO/MLSS control, dosing accuracy); plus OCEMS analyzers (pH, BOD/COD, TSS, ammonia, flow) at inlet/outlet with auto-samplers for continuous TNPCB/CPCB data transmission per guidelines. b) The sensors will be mounted on assets/piping with 4 - 20mA/Modbus outputs to edge gateways - enable remote alarming, energy savings, and compliance. c) dual SIM 4G industrial router, Ethernet switching, surge protected power supply, 1 kVA UPS/SMPS, IP rated enclosure, onsite wiring/terminations, PLC tag mapping, SDC broker configuration, FAT/SAT, as built drawings, and integration test reports.

Wiring, cabling & integration support at each STP Comprehensive wiring/cabling to interface the new IoT gateways with existing PLC/SCADA without disturbing plant operations. Includes shielded RS‑485 and Cat‑6 Ethernet cables, power wiring, trays, glands, ferrules, labels; loop checks, signal verification, grounding, surge protection, and documentation (cable schedule, I/O list, tag DB).

Security audit with SDC + licensing & source-code protection End‑to‑end cyber‑security hardening and licensing. Includes third‑party VAPT of SDC/application, firewall rules, SSL/TLS certificates, role‑based access controls, secure key creation for apps, source‑code protection, and final audit certificate with compliance documentation.

a) New AI enabled STP centralized monitoring software platform (Web + Mobile + API) exclusively to CMWSSB, Design & development of the custom Used Water Sentinel System (web, mobile, API). Modules: data ingestion, real time dashboards, alarms/ notifications, historical trends, analytics, role based access, reporting. Built on modern stack (React + Node/Python + PostgreSQL). Includes UI/UX, testing (unit/ integration/ UAT), and deployment. b) Secure role-based user access, realtime process visibility, performance dashboards, and automated reporting. The system will integrate advanced AI/ML algorithms for predictive analytics, enabling early detection of equipment deterioration, treatment inefficiencies, and compliance risks. Intelligent alerting through SMS, email and app notifications will support timely action, while built-in Root Cause Analysis tools will identify recurring failure patterns and operational gaps. c) The platform will auto generate regulatory performance and environmental compliance reports, monitor key STP KPIs such as influent/effluent quality, energy usage, aeration efficiency, chemical dosage and sludge treatment effectiveness, and maintain full audit trails with secure cloud data storage. Scalable for all current and future STPs of CMWSSB, the solution will ensure standardized operations, risk-free monitoring continuity and lifecycle-based decision support for improved wastewater treatment performance.

Cloud / Server infrastructure setup Provisioning of secure cloud infrastructure (AWS/Azure/private DC): virtual machines, databases, VPC/firewalls/VPN, backup and disaster recovery, monitoring (Grafana/CloudWatch), and hardened access (MFA). Targets ≥99.5% uptime and scalable growth for future plants.

Training & documentation Structured training for operators/engineers/admins and comprehensive documentation. Includes bilingual SOPs and user manuals (English & Tamil), video modules, hands‑on sessions at STPs/SDC, attendance records and certification.
