Core Evolution: EPANET vs. EPANET PLUS

Optimising water distribution systems (WDNs) demands precise, efficient, and scalable tools. For decades, the US EPA's EPANET has served as the global standard for simulating hydraulic and water quality behavior in pressurized pipe networks. However, as the engineering landscape evolves toward big data, smart cities, and machine learning, traditional desktop workflows hit performance ceilings.
