Subject:  How to Divide the Inflow at a Node in InfoSWMM

In SWMM 5 only the Kinematic Wave solution allows a flow divider at a node to divide the Inflow to node to two  downstream  links, but you can use the Inflow/Outflow Outlet type in InfoSWMM to divide the inflow based on a Inflow/Outflow Diversion Table (Figure 1).  For example, in InfoSWMM it is possible to have two downstream links from a Node that are Outlet types Inflow/Outflow so that the low flow goes down one link and the high flow goes down the other link (Figure 2 and Figure 3).   The low flow and the high flow  link  use different diversion tables in which the tables are constructed so that the flow is positive in one link and zero in the other to a dividing flow value and then zero and positive for the same two links after the dividing flow value ( 5 cfs in the example).

Figure 1.  Types of OUTLETS in InfoSWMM and SWMM 5

10 Tips for Effective Stormwater Management

Stormwater management is a growing concern in many communities as more and more natural areas are covered with impervious surfaces. This leads to more stormwater runoff and more potential for pollutants of all kinds to make their way into our water supply.

There are a lot of sources for stormwater pollution in even the smallest communities. Parking lots, driveways, streets, buildings, construction sites, and failed sewer systems all pose some kind of threat the quality of our water. Debris, litter, oils, grease, fertilizer, pesticides, and much, much more can build up in these locations, just waiting for the next storm to wash them into the nearest river or other body of water. Our stormwater management systems were designed to cope with a lot of this, but there are some simple things the entire community can do to make the process more effective.

  1. Involve and educate the community – Before anyone starts doing their bit to manage stormwater, they are going to need a reason. Find ways to help everyone in the neighborhood understand why these tips are important.
  2. Don’t dump anything in storm drains – Whether it’s just small pieces of litter or bits of plant matter, anything could start to clog up the system. Always dispose of your garbage properly.
  3. Choose non-toxic products – The less you use toxic chemicals (on your home, car, or lawn) the less we will see harmful substances getting into our water.
  4. Conserve and recycle – There are many reasons to be more conservative in our use of materials, and there are always opportunities to recycle, and in the case of stormwater management, this kind of behavior can have immediate benefits.
  5. Keep drains clear – If any litter or other debris is starting to build up near the stormwater drains, clean it away before the blockage renders the drains completely ineffectual.
  6. Check the septic system – Any leaks or other degradation to your system can have some pretty serious ramifications. As waste gets into the soil, rainwater can take it further until you have some real problems with the local water supply.
  7. Make cut backs – Too much chemical influence is never a good thing. Cut back on all the pesticides, herbicides, and fertilizers that you’ve been using on your lawn or garden. There’s a good chance you can still get great results with less of the chemical.
  8. Vehicle care – When you wash your car or change the oil, make sure that the runoff or any spill over is properly handled. Wash your car on the lawn or in a commercial facility, and always make sure that the oils is disposed of or recycled.
  9. Reduce paved areas – This isn’t something you can do over the weekend, but if you are looking at new landscaping or you’re remodeling your house, look at ways you can open the area to the rain and reduce the impermeable areas.
  10. Sweep, don’t hose – When you are cleaning off your driveway or sidewalk, take the time to sweep up the debris and dispose of it properly. Don’t just hose all that dirt, oil, and grease into the grass.

Polluted runoff is a real threat to the quality of our clean water, and while many of us don’t give a second thought to where the water from the last storm will end up, it’s a problem we can’t ignore. These tips are a simple way to get started and involve more people in the efforts to keep our water clean.

Subject:   Drawing features to show multiple attributes in InfoSWMM


Your network data usually has a number of different attributes that describe the features it represents (Figure 3). While you’ll commonly use one of the attributes to symbolize the

data—for example, showing one quantity in the InfoSWMM Map Display —you may sometimes want to use more than one.   One way to show multiple attributes in InfoSWMM is to copy layers and then use the Layer Properties to color, map or otherwise display the multivariable data (Figure 1).  For example, Figure 2 shows the important Subcatchment parameters of Slope, Imperviousness and Width as graduated colors, dots and a pie shape, respectively.


Figure 1.  Use the Symbology Tab to select the attribute you want to show and the way to show the attribute.

Subject:  RDII or Tri Triangular Unit Hydrograph in InfoSewer

The RDII method in InfoSewer is similar to the RDII or RTK  method in  InfoSWMM with some differences.    The RTK data for triangles 1, 2 and 3 are defined in the Unit Hydrograph but instead of individual R values, the overall R is set and the Percent R1,  R2 and R3 are defined based on the total  R.  R3 is calculated internally as 100 – R1 – R2.   Each loading manhole with RDII flow has a total  area, a hyetograph and a Unit Hydrograph.  The hyetograph has to be set at multiples of the unit hydrograph, so you can define the time or X columns with integers and then use the Block Edit command to change X to minutes by multiplying  by the Unit Hydrograph time (Figure 1).   You can use only one component if you set R1 or R2 to 100 percent or R3 to 100 percent by setting R1 and R2 to 0 percent (Figure 2).  The overall area of the Unit Hydrograph is divided amongst the loading manhole using the Subbasin Area (Figure 3).   The storm flows generated can be viewed using a Group Graph (Figure 4).

Adverse Slope Convention in SWMM 5

Subject:  Adverse Slope Convention  in  SWMM 5


If the slope of a link  is negative and the solution  is dynamic wave then the following data will be switched in link.c in SWMM 5.  All upstream data for the  link  is switched to the downstream end of the link  and  vice versa.   The means that if the flow  is from the original upstream node to the downstream node the flow  will  be negative in the output of  SWMM 5. 


Negative flow in SWMM 5 means:


1.   The link has an adverse or negative slope,

2.   The link  has reverse flow if the link slope is positive.

The Group is dedicated to achieving complete customer satisfaction through continuous improvements in the efficiency, effectiveness and economy of its services.

The city of Trento encompasses many suburbs of extremely varied geography and population concentrations, from large industrial areas in the Adige valley to tiny mountain villages in the neighboring Dolomites. “The area’s wastewater treatment systems experience characteristically extreme seasonal fluctuations in flows and loadings,” notes Matteo Frisinghelli, Dolomiti Reti’s General Manager of Water Services. “These factors, added to the complex and varied valley/mountain geography, make InfoWorks ICM’s fully-integrated 1D and 2D hydrodynamic simulation capabilities an ideal choice for the utility.”

Dolomiti Reti intends to use the industry leading integrated catchment modeling solution for cost-effective sewerage and drainage analysis throughout its varied catchments to help identify and resolve issues, optimize its networks, and undertake efficient and proactive forward planning. The software enables simultaneous modeling of below-ground and above-ground elements of catchments to accurately represent all flow paths and provide a holistic understanding of all the environmental processes taking place. 

The sophisticated InfoWorks ICM database design enables Dolomiti Reti to import, track, audit and interpret large quantities of data more easily and quickly than ever before. The software’s comprehensive planning and assessment capabilities provide the cutting-edge solution the company requires to offer optimized, cost-effective services to its customers.

“We are delighted that one of Italy’s leading utilities has chosen InfoWorks ICM for its complex wastewater and stormwater modeling requirements,” said Andrew Brown, Director of International Operations for Innovyze. “This vanguard solution is being rapidly adopted by progressive utilities around the world that are seeking its ease of use, flexibility, functionality, and unsurpassed power to resolve a wide spectrum of multi-faceted above and below-ground issues.”

Pennsylvania’s Lehigh County Authority Adopts InfoWorks CS to Manage its Wastewater Infrastructure 

Smart Water Modeling Network Modeling Solution To Support Authority in Optimizing Business Performance


Broomfield, Colorado USA, December 6, 2011 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced that the Lehigh County Authority (LCA), Pennsylvania, has selected InfoWorks CS for managing its wastewater facilities.

Located in southeastern Pennsylvania with the city of Allentown as its county seat, Lehigh County is positioned in the corridor between Philadelphia and New York City, with quick and easy access to both major metropolitan areas. LCA provides wastewater collection service for ten municipalities through a regional system of interceptors, as well as sewage collection and treatment services for individual communities where public wastewater systems are needed.

InfoWorks CS is a very powerful and comprehensive network modeling and simulation tool that will greatly assist us in planning level capacity analyses and in optimizing capital improvements for our sewer system,” said Michael Barron, P.E., Senior Project Engineer for LCA. “The software provides the flexibility, features, and computational speed to meet our dynamic sewer modeling challenges, and do so more quickly, without sacrificing the accuracy demanded by such complex projects.”

InfoWorks CS allows engineers and planners to produce fast, accurate and robust fully dynamic hydraulic modeling of any complex urban collection system network. Its capabilities encompass full modeling of backwater effects and reverse flow, open channels, trunk sewers, complex pipe connections and ancillary structures. Offering exceptionally fast and stable simulations, InfoWorks CS facilitates the swift modeling of total networks or any sub-network. Users may simulate models of up to 100,000 nodes with confidence that the results will be as accurate as those for far smaller models—making it a clear choice for the world’s leading wastewater utilities.

An essential tool for identifying and justifying cost effective infrastructure improvements, InfoWorks CS also provides a practical method for operational — including real time — control of the wastewater network. Other applications include urban flooding and pollution prediction and the modeling of water quality and sediment transport throughout the network.
