Technical Details of the Water Supply Management Software

IoT-Enabled Sensors and Actuators:

1. • Deployment: Smart sensors are installed throughout the water supply network to collect data on flow rates, pressure levels, temperature, and water quality indicators like pH, turbidity, and chlorine levels.
   • Integration: These sensors communicate via IoT protocols such as Lora WAN or MQTT, ensuring low-energy and high-speed data transmission to central servers.
   • Actuators: Smart valves and pumps are integrated into the system, allowing remote and automated adjustments to water flow and pressure.

Data Analytics and Machine Learning:

1. • Anomaly Detection: Algorithms analyze real-time and historical data to identify deviations, such as sudden drops in pressure that may indicate leaks.
   • Predictive Models: Machine learning models forecast equipment failures and water demand, enabling proactive maintenance and resource allocation.

Geographic Information System (GIS) Integration:

1. • Visualization: GIS mapping allows water authorities to visualize the entire distribution network, pinpoint issues, and simulate system changes.
   • Data Overlay: Combining GIS with weather data and population statistics helps in planning and decision-making.

SCADA (Supervisory Control and Data Acquisition) System:

1. • Automation: SCADA integration automates control of pumps, valves, and water treatment systems.
   • Remote Access: Operators can monitor and manage the system from centralized or remote locations.

Consumer Interaction:

1. • Smart Metering Devices: These devices provide real-time water usage data to households, accessible through mobile apps.
   • Feedback Loops: Residents can report issues directly through the system, creating a two-way communication channel.
