The document outlines a project by civil engineering students at Dr. N.G.P. Institute of Technology to implement an IoT-based water purifier monitoring system aimed at improving maintenance and access to clean drinking water on campus. The proposed solution aims to enhance the reliability of purifiers, reduce downtime, and optimize maintenance schedules through real-time monitoring and predictive maintenance. Additionally, a cost analysis indicates initial setup costs per purifier range from ₹10,500 to ₹20,500, with potential annual savings and a payback period of 2-3 years due to reduced maintenance and improved water quality.

User Notifications
The system provides a reliable and transparent view
of water purifier operations. Maintenance staff and
campus authorities can ensure that all purifiers are
functioning optimally, promoting a trustworthy
system where issues are addressed promptly.
Integrity
Traditional maintenance relies on reactive
approaches (fixing after breakdowns), while IoT
introduces predictive capabilities, anticipating
failures before they occur. This forward-thinking
approach reduces downtime and operational costs.
Innovation
Using IoT to monitor and maintain water purifiers
introduces a creative solution to a traditional
problem. It combines technology, sustainability, and
convenience in a way that optimally serves the
campus community.

7. IMPACT AND BENEFITS
Integrating IoT-based sensors for real-time monitoring and predictive maintenance of
water purifiers on the NGP campus would have significant benefits. First, it would
enhance the reliability of the purifiers by continuously tracking their operational status,
ensuring that maintenance teams are promptly alerted to potential issues before they
lead to breakdowns. This predictive maintenance approach would minimize downtime
and extend the lifespan of the equipment, ultimately reducing repair and replacement
costs. Additionally, the system would provide real-time insights into water quality,
ensuring the safety of drinking water for students and staff. With a centralized
monitoring platform, maintenance becomes more efficient and proactive, leading to
improved resource management and better planning of maintenance schedules.
The system would also foster greater user trust in campus facilities, as users can be
confident in the consistent availability of safe drinking water. Overall, this smart solution
would promote a more sustainable, cost-effective, and health-conscious campus
environment.
