KPI Name Water Supply ICT Monitoring
KPI No. EC: ICT: WS: 2A Type: Core Type: Smart

Definition / Percentage of the water distribution system monitored by ICT
Description

Rationale / The city should report on the extent that a SCADA (supervisory control and data
Interpretation / acquisition) system (or similar system) has been implemented to cover the water
Benchmarking supply system.
The system may include the following features:
• Central control facility
• Level transducers that track water levels in reservoirs and tanks
• Pressure transducers in pipes that ensure that water is pumped and is flowing
efficiently
• Flowmeters that measure the actual delivery of water
• Pressure-sustaining and pressure-reducing valves that open and close
incrementally to adjust the rate at which the water flows
ICT control has shown to be effective in improving the efficiency of a water supply
system and an effective tool for determining areas of water loss.
An increasing trend and higher values are considered positive.
Methodology Calculate as:
Numerator: Length of system monitored by ICT (km).

Denominator: Total length of total system (km).
Multiply by 100.
Unit Percentage
