Collection Methodology for Key Performance Indicators for Smart Sustainable Cities

Dimension Economy
Sub-Dimension ICT
Category Water and Sanitation
KPI Name Water Supply ICT Monitoring
KPI No. EC: ICT: WS: 2A Type: Advanced 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; and
▪ 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

SDG Reference(s) SDG Target 6.4: By 2030, substantially increase water-use efficiency across all
sectors and ensure sustainable withdrawals and supply of freshwater to address
water scarcity and substantially reduce the number of people suffering from water
scarcity.
SDG Indicator 6.4.1: Change in water-use efficiency over time.
