IoT Platform for Smart Water
Overview
ASTRI has developed 2 solutions.
Integrating the technologies of t-distributed Stochastic Neighbor Embedding (t-SNE) and Principal Component Analysis (PCA) to build the Smart Water Analysis System (the Analysis System) which perform data filtering that identifies anomalies in real-time.
LoRaWAN-based Hong Kong Wireless Smart Water Metering System Standard and its Reference Design (the System Standard) is to facilitate the retrofitting of smart metering system to existing buildings.

Problem addressed
Traditionally SCADA data analysis and water meters reading are performed manually.
SCADA data from many devices have to be analyzed.
Meter reading is done once every 4 months and no abnormal alarms can be generated. WSD is introducing wired smart water metering into new buildings, but which is difficult to retrofit into existing buildings.
Innovation
- The analysis system turns complicated water flow data into scatter plot graph clusters by t-SNE and 2-dimension data by PCA to enhance anomaly identification.
- The System Standard is based on WSD requirements, OFCA regulations, and LoRaWAN standard and the first in Hong Kong. It facilitates a region-wide deployment of wireless AMR system in the future.
- The Reference Design includes a low power consumption meter interface unit (MIU). It is used to verify the System Standard. It also works a tool to support SME in development.
Key impact
- Real-time and effective way to analysis and identify anomaly in SCADA.
- Raise public' awareness in water conservation with an estimated saving of 1.8M m3 of water per year.
Application
- Dimension reduction and data filtering
- Wireless automatic meter reading / smart water metering
