Technical Performance Evaluation of Water Distribution Networks based on EPANET

Abstract This paper explores the use of Technical Performance Indexes (TPIs) to assess the operational performance of Water Distribution Networks (WDNs) and exemplifies its suitability to easily identify problematic zones. The paper also points out some problems associated with the existent TPIs and proposes new analysis tools to avoid these difficulties. These new analysis tools (such as state variable slack and constraint violation) are conjugated with the pressure-driven simulation model for illustration purposes, including operational performance assessment during pipe bursts or firefighting scenarios, and to identity and account for the “demand not satisfied” due to those events.
