Innovyze Announces Worldwide Support for EPANET and SWMM5

Innovyze Announces Worldwide Support for EPANET and SWMM

Groundbreaking Initiative Facilitates Technology Transfer of Sustainable Water Infrastructure Models Between Global Communities

Broomfield, Colorado, USA, March 31, 2015

Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced worldwide support for USEPA’s flagship EPANET and SWMM public domain software. By offering its technical expertise to the EPANETand SWMM communities, Innovyze is ensuring ongoing maintenance of these free software models of sustainable stormwater, wastewater, and water supply systems.

Sustainable water infrastructure models are used throughout the world for the planning, analysis, design, and research of stormwater, wastewater, and drinking water distribution management. SWMM can model the generation and transport of runoff and sanitary flows as well as estimate the production of pollutant loads associated with this runoff in storm, sanitary or combined sewers. With the recent inclusion of hydrologic performance of specific types of green infrastructure low impact development (LID) controls the model can be used to consider both grey infrastructure approaches (e.g., pipes, tunnels, high rate treatment), and potentially more cost-effective green infrastructure approaches (e.g., rain gardens, permeable pavement, rain barrels) for managing stormwater. EPANET can help water utilities maintain and improve the quality of water delivered to consumers through their drinking water distribution systems. It can also be used to plan and improve a system’s hydraulic performance. The model can assist with pipe, pump, and valve placement; sizing; energy minimization; fire flow analysis; vulnerability studies; and operator training. Together, these models give municipalities the tools to help them develop cost effective green and grey water infrastructure options that reduce the release of untreated wastewater and improve the availability of safe drinking water.

“Innovyze is a pioneer in cutting edge sustainable water infrastructure modeling research and development,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “The company’s industry-leading GIS-centric InfoWater and InfoSWMM product suites greatly expand on the simulation and analysis capabilities ofEPANET and SWMM5 models. Ongoing maintenance of EPANET and SWMM is important both to us and to the global water and wastewater communities. It ensures the usefulness and longevity of these products for their users. We are pleased to launch this initiative to help further sustain the world’s wet infrastructures and provide solutions to such challenging problems as climate change, water security, and environmental compliance.

“We hope to continue to inspire water modelers worldwide and provide them the power tools to do the things that inspire them so that together we can build and sustain resilient water infrastructures that help drive the economy and create a better world for everyone.”

For more information about these products, visit Innovyze at www.innovyze.com and select “EPANET” or “SWMM.” Training classes onEPANET and SWMM will be available through the Innovyze University, http://www.innovyze.com/education/.
 
Pricing and Availability
Both EPANET and SWMM can be downloaded free directly from the Innovyze web site at www.innovyze.com. Access to the Innovyze User Forums is also available to seek answers and exchange information with the global water and wastewater modeling communities (http://forums.innovyze.com/).

How to develop a unit area hydrographs(surface water only) and pollutographs in SWMM5 for use in SUSTAINs(System for Urban Stormwater Treatment Analysis and INtegration) land module.

Hello sir, seasons greeting.  I am very new to the SWMM5 and working on a project in which i have to develop unit hydrograph and pollutograph in SWMM. please help me out.explain me a detailed procedure to develop hydrograph and pollutograph. Actually I have to develop unit area hydrographs for use in SUSTAINs land module and also have to develop pollutographs for each landuse and subcatchment (Based on unit area hydrographs and EMC's). Thanks in adavance and will be waiting for your valuable suggestions.

Lumped catchment reacts too fast

I lumped my catchment - disregarding the details of the sewer nework and repalacing it with an equivalent subcatchment -  but it offten reacts faster than the detailed sewer network model. Any research or idea on this? I tried to include a  link down stream of the subcatchment which improved the fit between detailed and lumped model.

Parameter for 'delaying' modelled flow

Hi, I am trying to calibrate a subcatchment. I have semi-automatically tried to calibrate catchment width, slope, Manning's n for pervious and impervious, depression storage for pervious and impervious. I came up with a flow curve shape which looks like the measured flow but the modelled flow is starting 30min earlier. I tried to change many of those parameters I described but still I can not reduce the 30min gap. Since it is a very small catchment I don't think this is due to spatial distribution of rainfall. So any other  idea why modelled flow starts 30min before measured?

underground LID modeling

Hi everybody, if anyone can help me with this: How can I develope in SWMM5, an infiltration facility (like infiltration trench, or better, like a linear - not spot  soakway) which is located underground (which means it does not receive rainfall itself but only runoff is directed into it). Thank you in advance.

How do SWMM simulate the infiltration and exfiltration from a river ?

Hello, everyone, I study a area which always occurs infiltration in dry-weather and exfiltration in wet-weather, for there is a stream nearby the sewer. When the level of the stream is higher than that of the sewer, it happens the infiltration, otherwise the exfiltration happens.  So if there is a proper way to simulate the process of the infiltration and exfiltration ? I can set a pipe between the junction and the stream, but how to describe a stream in SWMM ? and how to set the level of the stream? Thank you!

Time adjusted rule for orifice setting

I want to control opening and closing of an orifice depending on the flow in a downstream link. I want to close the orifice for 15min if the flow in the d/s exceeds say 50 LPS, after 15 min I want to check again the flow in the link and adjust the opening-closing of the orifice depending on the flow above-below 50LPS. How can I writet a rule which can solve this problem?

MatLab and SWMM5

the successful way to combine MATLAB with SWMM

Hi everyone,  I found there were many questions about how to call SWMM in matlab, and this problem has bothered me for a long time.  Now I find a way to combine MATLAB with SWMM, it solve my problem, and I want to share with your guys .  The principle is to read and change .inp file of SWMM, and call swmm in MATLAB, then read the .rpt file to import data to matlab workspace.  The step and the main command are like below: 1. use  the command 'textscan' in matlab to read .inp file, the result…

Hello folks, I was happy for the fact that I found this website but my excitement didnt last long! I read all of the dicussions here but I couldnt find a post which directly show me how to connect Matlab to SWMM. Yes, you do parallel processing and all of the fancy stuff with SWMM but I still don't know how call the SWMM! I may have missed something. I'm looking for a sample code to call SWMM from Matlab and do some changes to calibrate and essentially optimize the specific parameters. I think…

editing subcatchment, node and conduit parameters using swmm5 interface commands

How can MATLAB change some parameters in SWMM5 inp file?

Dear all,I want to use MATLAB and SWMM5 for optimal calibration. In doing so:1) MATLAB has to generate some random values (decision variables) as inputs for SWMM5 (here is width of subcatchments2)Previous subcatchment widths replaced with New ones. So it is necessary that MATLAB reads inp file and replaces older subcatchment widths with generated values.3)SWMM5 has to run in DOS version (swmm54)MATLAB has to read rpt file and picks some result to calculate objective function5) generate other…
