Exploring Resilience of Community Water Networks
through CPHS-Enabled Platform

Supervisor: Professor Nalini Venkatasubramanian
Motivations
WATER – a precious natural
resource
Water
Infrastructure
■ A critical resource and lifeline service.
Resilience Concerns
■ Water infrastructure has been developed over
decades (centuries sometimes).
■ Resource wastage.
■ Become large, complex and vulnerable to failures.
■ Damaged to underground pipelines is often
hidden.
■ Close to 237,600 breaks per year in the US.
■ Approximately $2.8 billion lost in yearly revenue
(AWWA).
■ Period of drought increases water demand and
adds strain to water supply.
■ Community disruptions.
■ Contamination.
■ Threat to public health.
Objectives
AquaSCALE Framework
■ Understand resilience
issues in cyberspace
before instantiating them
into a physical
infrastructure.
■ Identify operational
degradation in aging
infrastructures.
■ Improve speed and
accuracy of damages
estimation.
■ Reduce service
restoration time.
■ Current Research: Leak Detection
1. Twitter Data Analysis
■ Extract related information (Leak?
Where? Reason? Damage?)
■ Identify vulnerable locations
■ How people report the leak event
■ …
2. Social Media Data Collection APP
3. Testbed for Monitoring and Controlling
Water Network
