EPANET Plus: A Technical Overview

EPANET Plus: The Next Generation of Water Distribution System Modeling

2. Pump Energy Optimization

By coupling EPANET Plus with an optimization script (e.g., Python + Pyomo), utilities can find the cheapest pump scheduling strategy under time-of-use electricity tariffs while maintaining minimum pressure constraints.

Part 6: The Future – EPANET Plus and Digital Twins

The rise of Digital Twins (live virtual replicas of physical water systems) relies entirely on the architecture of EPANET Plus. epanet plus

Why?

• Real-time data integration: Plus engines can ingest SCADA data every 15 minutes and update demand patterns on the fly.
• Machine Learning: The time-series output of Plus models is perfectly formatted for LSTM neural networks to predict pipe bursts.
• Smart Valves: As utilities install pressure-reducing valves (PRVs) with IoT controllers, they need EPANET Plus’s feedback control logic to simulate them before installation.

The EPA is currently funding the EPANET 3.0 research, which will likely include AI-assisted calibration and full energy-carbon accounting. But make no mistake: EPANET Plus is the bridge from the static past to the adaptive future. EPANET Plus: A Technical Overview EPANET Plus: The

4. LID and Green Infrastructure

For stormwater and combined sewer overflow modeling, EPANET Plus includes modules for rain barrels, permeable pavements, and green roofs. This bridges the gap between water distribution (potable) and stormwater management (non-potable). Real-time data integration: Plus engines can ingest SCADA

Key features worth highlighting

• Programmatic API: Designed for easier calls from Python, .NET, or other languages—great for automation.
• Cleaner data structures: Nodes, links, and controls are exposed in ways that are simpler to query and modify.
• Compatibility with EPANET inputs: Keeps support for familiar INP files while enabling richer programmatic manipulation.
• Improved support for extended attributes and metadata: Useful for GIS linking, tagging assets, and exporting results.
• Expanded quality and extended simulation hooks: Easier to plug in alternative water-quality models or custom control logic.

Basic Workflow (using Python + epyt)

from epyt import epanet
Option B: The Commercial Path (User Friendly)

InfoWater Pro (Autodesk): Fully integrated with AutoCAD and ArcGIS; runs the EPANET Plus engine natively.
WaterGEMS (Bentley): Has supported Plus-engine features like pressure-dependent demands since version 10.

3. Water Quality Redesign
The new engine supports species-specific reaction kinetics. You can now model chlorine decay alongside disinfection by-products (THMs) simultaneously. It also supports advection-reaction solvers that are 10x more stable than the previous generation.
