EPyT-Flow -- EPANET Python Toolkit - Flow

EPyT-Flow is a Python package building on top of EPyT for providing easy access to water distribution network simulations. It aims to provide a high-level interface for the easy generation of hydraulic and water quality scenario data. However, it also provides access to low-level functions by EPANET and EPANET-MSX.

EPyT-Flow provides easy access to popular benchmark data sets for event detection and localization. Furthermore, it also provides an environment for developing and testing control algorithms.

Installation

EPyT-Flow supports Python 3.9 - 3.12

Note that EPANET and EPANET-MSX sources are compiled and overrite the binaries shipped by EPyT IF EPyT-Flow is installed on a Linux system. By this we not only aim to achieve a better performance of the simulations but also avoid any compatibility problems of pre-compiled binaries.

PyPI

pip install epyt-flow

git clone https://github.com/WaterFutures/EPyT-Flow.git
cd EPyT-Flow

Quick Example

from epyt_flow.data.benchmarks import load_leakdb_scenarios
from epyt_flow.simulation import ScenarioSimulator
from epyt_flow.utils import to_seconds


if __name__ == "__main__":
    # Load first Hanoi scenario from LeakDB
    network_config, = load_leakdb_scenarios(scenarios_id=["1"], use_net1=False)

    # Create scenario
    with ScenarioSimulator(scenario_config=network_config) as sim:
        # Set simulation duration to two days
        sim.set_general_parameters(simulation_duration=to_seconds(days=2))

        # Place pressure sensors at nodes "13", "16", "22", and "30"
        sim.set_pressure_sensors(sensor_locations=["13", "16", "22", "30"])

        # Place a flow sensor at link/pipe "1"
        sim.set_flow_sensors(sensor_locations=["1"])

        # Run entire simulation
        scada_data = sim.run_simulation()

        # Show sensor readings over the entire simulation
        print(f"Pressure readings: {scada_data.get_data_pressures()}")
        print(f"Flow readings: {scada_data.get_data_flows()}")
