Overview
PySWMM is a Python language software package for the creation,
manipulation, and study of the structure, dynamics, and function of
complex networks.
With PySWMM you can load and manipulate USEPA Stormwater Management
Models. With the development of PySWMM, control algorithms can now be
developed exclusively in Python which allows the use of functions and
objects as well as storing and tracking hydraulic trends for control
actions.
As of version v1.1.0, PySWMM includes new features to process metadata
and timeseries stored in SWMM binary output file.
Who uses PySWMM?
PySWMM is used by engineers, modelers, and researchers who want to
streamline stormwater modeling optimization, controls, and
post-processing results.
Goals
PySWMM is intended to provide

tools for the study of the structure and dynamics within USEPA
SWMM5,
a standard programming interface and graph implementation that is
suitable for many applications,
a rapid development environment for collaborative, multidisciplinary
projects,
an interface to USEPA SWMM5,
development and implementation of control logic outside of native
EPA-SWMM Controls,
methods for users to establish their own node inflows,
a coding interface to binary output files,
new modeling possibilities for the SWMM5 Community.

Install
Get the latest version of PySWMM from
PyPI See the Quick
Guide!
$ pip install pyswmm

As of version 1.3.1, pyswmm can be installed with specific versions of the SWMM engine ranging from 5.1.14 to 5.2.4 using pip extras:
$ pip install pyswmm[swmm5.2.4]

SWMM and Python Compatibility Table

Usage
A quick example that steps through a simulation:
Examples:
See the Latte Example
from pyswmm import Simulation, Nodes, Links

with Simulation(r'Example1.inp') as sim:
Node21 = Nodes(sim)["21"]
print("Invert Elevation: {}". format(Node21.invert_elevation))

Link15 = Links(sim)['15']
print("Outlet Node ID: {}".format(Link15.outlet_node))

# Launch a simulation!
for ind, step in enumerate(sim):
if ind % 100 == 0:
print(sim.current_time,",",round(sim.percent_complete*100),"%",\
Node21.depth, Link15.flow)

Opening a SWMM binary output file and accessing model metadata and
timeseries.
from pyswmm import Output, SubcatchSeries, NodeSeries, LinkSeries, SystemSeries

with Output('model.out') as out:
print(len(out.subcatchments))
print(len(out.nodes))
print(len(out.links))
print(out.version)

sub_ts = SubcatchSeries(out)['S1'].runoff_rate
node_ts = NodeSeries(out)['J1'].invert_depth
link_ts = LinkSeries(out)['C2'].flow_rate
sys_ts = SystemSeries(out).rainfall
