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.
