The paper proposes a system dynamics framework to translate and evaluate different water and wastewater system architectures under operational disruptions, using four architectures (SWAT testbed, SWRO desalination plant, a wastewater treatment plant, and a water management testbed). It examines six failure scenarios including raw water shortage, supply–demand imbalance, storage tank leakage, sensor failures, and flow delays, reporting large performance differences across architectures with convergence times of 23–83 minutes and a baseline output of 19 liters/minute. The authors validate the framework in this modeling context and state a major caveat that the work is a preprint and not peer reviewed, with potentially preliminary data. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Water and wastewater systems are critical infrastructure serving growing urban populations, yet their increasing complexity and technological integration make them vulnerable to diverse operational disruptions and emerging threats. The absence of standardized frameworks for evaluating different system architectures limits the ability to assess, compare, and enhance infrastructure resilience. This study presents a system dynamics framework that enables systematic translation and evaluation of different water and wastewater systems and architectures. This study developed and validated the framework using four architectures: SWAT: Secure Water Treatment Testbed), SWRO: SWRO desalination plant, the Wastewater Treatment Plant, and the Center Water: Water Management Testbed. Six critical failure scenarios were examined: baseline operations, raw water shortage, supply demand imbalances, storage tank leakage, sensor failures, and flow delays. Results demonstrate significant performance variations across architectures, with convergence times ranging from 23-83 minutes and a baseline of 19 liters/minute. The water and wastewater system performance, reliability, efficiency, and resilience are functions of the conceptual and architectural design. This study provides water utility managers and policymakers with a systematic tool for resilience assessment and offers cybersecurity researchers a systems-thinking methodology for investigating infrastructure vulnerabilities.
