Simulated pump outages split water service recovery from pressure recovery
Original title: Compound Environmental Operating Stress and Cyber-Induced Pump Disruption in Water Distribution Networks: Matched Hydraulic Impacts, Service Continuity, and Sustained Recovery
In 192 verified scenarios, 12-hour Net1 outages averaged 404.96 m³ unmet demand while Net3 kept full delivery.
A simulation study applies hypothetical cyber-induced pump outages to two EPANET benchmark water networks, Net1 and Net3, using the Water Network Tool for Resilience. The design has 288 simulation records and 240 configurations, including 192 verified attack scenarios with four- and twelve-hour outages, six hydraulic setups, and four mitigations. Twelve-hour outages left an average of 404.96 m³ of unmet demand in Net1, while Net3 delivered all modeled demand despite pressure deviations. Sustained pressure recovery occurred in 103 of 192 scenarios, and 65 of those later relapsed, yet every scenario met the post-outage water-service criterion.
Unconfirmed: Outages and environmental stress are hypothetical simulations, not observed attacks or calibrated climate events.
- Combined mitigation removed unmet demand in the evaluated Net1 scenarios.
- Shortening the outage produced the highest sustained-pressure-recovery count.
- Pressure recovered in 103 of 192 scenarios, then relapsed in 65.
- Environmental stress is treated as a sensitivity assumption, not measured climate impact.

1 min read at arxiv.orgDigitally controlled water distribution systems must maintain service during disruptions, yet restoring water delivery does not necessarily ensure hydraulic recovery. This study evaluates cyber-induced pump outages under hypothetical environmental operating stress using two EPANET benchmark networks (Net1 and Net3) simulated with the Water Network Tool for Resilience.
