KPI Name Drainage / Storm Water System ICT Monitoring
KPI No. EC: ICT: D: 1A Type: Advanced Type: Smart

Definition / Percentage of drainage / storm water system monitored by ICT
Description

Rationale / Optimal control techniques in urban drainage networks help generate control
Interpretation / strategies ahead of time, based on current and past readings of the telemetry
Benchmarking system, to minimize flooding and control sewer overflow.
Real-time control of an urban drainage system may be local or global. When local
control is applied, flow regulation devices only use measurements taken at its
specific location.
While this control structure is applicable in many simple cases, in a large city, with
an interconnected sewerage network and a complex network of actuators and
sensors, it may not be the most efficient alternative. Conversely, global control,
which computes control actions taking into account real-time measurements all
through the network, is likely to make the best use of the infrastructure capacity and
all the available sensor information.
ICT control has shown to be effective in improving the efficiency of a drainage
system and can minimize instances of urban flooding.

An increasing trend and higher values are considered positive.
