Epanet Plus Guide

Adds the ability to model complex, interacting chemical and biological species (e.g., disinfectant by-products, bacterial regrowth). EPANET-PLUS

This is made possible by the introduction of . In the original EPANET, a node always received its full demand, even if pressure dropped to zero—a physically impossible scenario that gave false confidence during fire-flow analysis or pipe breaks. EPANET Plus natively implements PDD, where actual outflow depends on available pressure. Below a minimum pressure, demand drops; above a desired pressure, full demand is met. This single feature transforms the accuracy of failure scenarios, leak detection studies, and low-pressure zones. epanet plus
