The newer option for SWMM 5 culverts uses three culvert classifications and associated equations to compute the inlet controlled flow into a culvert using the FHWA (1985) equations. The culvert code in the culvert.c code of SWMM 5 uses:
1. Two Equations for Unsubmerged culvert flow,
2. One Equation for the Transition flow, and
3. One Equation for Submerged flow.
If you use the culvert option in later versions of SWMM 5 then when the inlet control equation flow is less than the computed St Venant flow then the FHWA equations will be used for the current iteration in the SWMM 5 Dynamic Wave Solution.
Understanding Your Model Output in H2oMAP SWMM and InfoSWMM |
Three Hidden Secrets to Speeding up your SWMM 5, H2OMAP SWMM or InfoSWMM Model |
Minimum Time Step Average Time Step Maximum Time Step
Minimum Time Step (sec) 0.984
Average Time Step (sec) 9.071
Maximum Time Step (sec) 30.000
Percent in Steady State (%) 0.000
Average Iterations per Time Step 4.821
Use a maximum time that will lower your average iterations per time step to speed up the simulation,decrease the maximum time step to lower the number of iterations, use equivalent conduit lengthening to increase
the minimum time step, the model is fastest if the minimum and maximum time steps are not too small or large compared to the average time step. Adjust the stopping toleranceand the number of iterations if you can to speed up your model
You can also decrease the number of iterations or the stopping tolerance to speed up the model or improve the continuity error of the model. If you are doing a continuous simulation then you can have a reduced graphical output data set to speed up the simulation
If you have a duo or quad core computer another option to speed up the simulations is to use 1, 2, 3 or 4 cores for the simulation

Innovyze Releases InfoWater Generation V8.5,
Defining New Era of Leadership in Analytics-Centric Asset Management
Latest Release Equips Communities with Groundbreaking Valve Criticality Assessment Power
Broomfield, Colorado USA, October 25, 2011 — In its ongoing quest to equip the global water industry with the world’s most powerful and comprehensive GIS-centric infrastructure modeling and management solutions, Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced the worldwide availability of the V8.5 Generation of InfoWater for ArcGIS (ESRI, Redlands, CA). InfoWater has long been renowned for its legendary power, speed, and comprehensive toolsets and extensions. With this release, Innovyze has further refined the superb water supply and distribution modeling and analysis features that have helped make the software a leading choice among the world’s top water utilities.
Built atop ArcGIS, InfoWater seamlessly integrates sophisticated analytics, systems dynamics and optimization functionality directly within the ArcGIS setting. From fire flow and water quality simulations, valve criticality and energy cost analysis to pressure zone management and advanced Genetic Algorithm and Particle Swarm optimization, the InfoWater product suite comes equipped with everything water utility owner-operators need to best plan, design, operate, secure and sustain their distribution systems. The software also serves as a base platform for advanced modeling, operational, and capital planning extensions. Among these critical applications are IWLive (real-time operations and security), InfoWater UDF (unidirectional flushing); CapPlan (risk-based capital planning); InfoWater MSX (multi-species, temperature, and particle transport/deposition modeling); InfoSurge (surge/transient analysis); and Sustainability (carbon footprint calculation).
Users will discover a variety of improvements in network analysis and valve criticality assessment throughout InfoWater V8.5. For example, when a network simulation terminates prematurely at any specific time during an extended period simulation (EPS), users can now view all the temporal results up to that point. GIS layers (feature classes) representing isolation valves can now be directly utilized for identifying the ones that most critically affect the scale or impact of any potential distribution system outage. An improved algorithm then automatically pinpoints all critical valves as well as all pipes with flow reversal caused by valve operation. Since flow reversal is an indicator of sediment resuspension and subsequent water quality complaints, the new functionality allows utility operational and field staff to run a simulation on a mobile device before operating any valve to understand its resulting impact. By determining critical valves in this way, water utility owner-operators can effectively prioritize expenditures on solutions like maintenance, replacement, SCADA, motorization, and control, and optimal placement of new valves. Users can also create countless “what if” scenarios that quickly model the effect a proposed design or operational change could have on the entire system and its customers. The result is better, more accurate valve criticality assessments completed more quickly, with improved efficiencies, operations and customer satisfaction at every step.
These enhancements propel the InfoWater family of solutions into the next generation, carrying on Innovyze’s time-honored practice of continually adding critical value to its software and bringing unsurpassed modeling and design capabilities into the mainstream. The suite has the robustness and feature set needed to handle the most demanding analyses. Yet it’s intuitive enough for a new user to master without a drawn-out learning curve, making it the ultimate GIS-centric decision support tool for water supply and distribution systems. Like all Innovyze products, it’s backed by unparalleled high-touch technical support. For an even faster return on investment, organizations may opt to call on Innovyze Implementation Services to accelerate deployment, integration and implementation of best modeling practices.
I want to import ArcGIS data into SWMM. How can I do this? If possible I want to include SWMM into ArcGIS as add-in, any help?
New Installl from INPPINS - I downloaded it
The following was added by RED
Link to INPPINS site (click on image)
Step 1. Pump Startup and Shutoff Depth
Depths to turn the Pump On and turn the Pump Off. In this example, the pump will be off when the Wet Well Depth is less than 2 feet, the Pump will be off between a Wet Well Depth between 2 and 5.75 feet if the Pump is currently Off and the Pump will be On between a Wet Well Depth between 5.75 and 2 feet.
Step 2. RTC Rule for the Pump Setting when the Wet Well Depth is less than 6.25 feet. We need to add the AND statement so that the setting is only reset when the Pump is On. You do not want the pump setting to be reset when the pump should be off.
Result 1: The Pump Speed Ratio tells you the Pump Setting
Result 2: RTC Control Rules in the RPT File if you click on Show Control Actions
Result 3: The depth at the Wet Well and the Flow in the Pump
Result 4: A mixed graph of the Wet Well Depth and Pump Flow shows the effect of the RTC.
Result 5: The RTC Rule can also been seen flow to the Pump Curve.
v The goal of the link lengthening in SWMM 5 it to meet the CFL time step condition for the full link depth and full link velocity at the chosen lengthening time step. If the link does not meet the CFL condition then this means the time step needed is smaller than your selected lengthening time step. SWMM 5 will make an hydraulically equivalent longer link with a smaller roughness but the same full flow velocity as the shorter link.
v If you are running a simulation in which all of the pipes are exactly full – no surcharge in any pipe – and the variable time step then there would be no need for SWMM 5 to use anything other than the minimum of the routing or lengthening time step. However, since most real networks have a mixture of partial flow, surcharged flow and pressure flow, the actual time step depth, velocity/Froude Number is different than the assumed full depth and full flow velocity. For example, the depth can be higher at one end of the pipe and the velocity higher than full flow velocity due to the water surface slope being higher than the bed slope. The only way SWMM 5 can now satisfy the CFL time step condition since the modified length is fixed is to lower the variable time step.

Hello:
I am wondering how the "mass reacted" is calculated. I am getting results that don't really make sense. I am guessing it has something to do with the way I wrote my treatment expressions.
Also, I am trying to express the nitrification process (assuming a 90% conversion of NH4+ to NO3-). I have defined the rain concen. of the NH4+ ("X"). In the subsequent layer, I want the converted concen. of the NH4+ (0.90*X) to be added to the rain concen. of NO3- (defined as "Y"). What is the best way to express this in a treatment expression?
Thanks,
Michelle
Hello,
Since in the current version of SWMM doesn't allow the user to change the width of the Priessmann slot, I would like to know how EPASWMM really develops that value for different simulations or whether it's a constant value.
Subject: Reading the Output of Older SWMM 5 versions in Newer SWMM 5 Versions
It is very easy to read the output graphs and output text file from older versions of SWMM 5 in newer versions of SWMM 5 as long as the rules are followed:
1. You need to have the RPT file for the InputFileName or InputFileName.RPT
2. You need to have the OUT file for the InputFileName or InputFileName.OUT
3. The File Size for InputFileName.RPT is greater than 0
4. The Run Status for InputFileName.OUT is true based on the tests in CheckRunStatus
a. // Starting from end of file, read byte offsets of file's sections
b. // Read # time periods, error code & file signature
c. // Read file signature & version number from start of file
d. // Check if run was completed
e. // Check if results were saved for 1 or more time periods
f. // Check if correct version was used
g. // Check if error messages were generated
Figure 1. The RPT File or OUT File is not saved unless you 1st save the Current Simulation Results.

Colorado’s Largest Combined Water and Sanitation District Turns to Innovyze |
|||||
|
Broomfield, Colorado USA, September 20, 2011 — Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced that the South Adams County Water and Sanitation District (SACWSD), Colorado, has selected Innovyze’s InfoSewer to support its comprehensive wastewater system improvement projects. Formed in 1953, the district serves water and provides wastewater collection services in the City of Commerce City and adjacent areas of unincorporated Adams County. It is presently the largest combined Water and Sanitation District in the state of Colorado, covering over 65 square miles and serving nearly 50,000 customers. Its wastewater collection system consists of over 300 miles of sewer mains, ranging from 8” to 30” in diameter. “Effectively managing our wastewater collection system requires sophisticated network analysis and GIS integration capabilities — and Innovyze InfoSewer superbly combines both these strengths,” said Jim Pankonin, P.E., Distribution & Collection Systems Manager for SACWSD. “The software’s ease of use and intuitive interface, seamless ArcGIS integration, speed, and broad functionality will allow us to create a powerful enterprise wide engineering GIS modeling environment — one that will greatly enhance our effectiveness in managing our wastewater system and planning for the future. We look forward to fully leveraging this superior technology to optimize our capital improvement program and continue delivering outstanding service to our customers.” Built atop ArcGIS (Esri, Redlands, CA) with native geodatabase support, InfoSewer is used by municipal engineers, consultants, and planners worldwide to create detailed, accurate models of sanitary and storm sewer collection systems. These models enable users to assess the effect of new developments, zoning changes, and other additional loads on system flows. They also help pinpoint current and future problem areas; determine how best to restore capacity lost to infiltration and inflow with the least rehabilitation; predict unwanted overflow events and backups; develop sound, cost-effective improvement alternatives; meet environmental regulations; and enhance community relations. |
Note: Attached is an example SWMM 5 model that has all 57 culvert types possible in SWMM 5 in one model. The culverts are 57 small individual networks consisting of an inflow node, an upstream open channel, upstream node for the culvert, culvert link with culvert code, downstream node of the culvert, downstream open channel and finally an outfall node. The culvert code and the shape of the culvert determine which FHWA equation is used to determine the flow INTO the Culvert during the simulation:
1. The flow from the St Venant Equation or
2. The flow from the FHWA equation
The minimum flow is used by the program.
Note: How Dry Weather Flow is Used in InfoSWMM at a Node
There are four components to the Dry Weather Flow (DWF) in InfoSWMM:
1. The mean flow in user units at the node,
2. The DWF Allocation Code – if you are using the DWF Allocator
3. The Pattern for Weekday, Weekend etc for the mean flow.
The data is entered or entered for you in the Node Inflow Icon or the Operations Tab of the Attribute Browser

You can also make global changes to your DWF using the Node DWF DB Table Under Extended Element Modeling Data
This note attempts to explain both how the head upstream and the head downstream of a weir in SWMM 5 is calculated compared to the weir crest elevation and also to explain how the weir is presented in the HGL plot of SWMm 5. There has been confusion in the past concering how the weir is shown compared to the actual weir calculations. The node head is calculated obviously at both ends of the weir but the head over the weir is always based on H1-Crest or H2-Crest (Figure 1) and hence the weir should look flat – to the weir the downstream head is important but NOT the downstream node invert so the weir really is flat and should look flat in the HGL Profile across the weir (Figure 2). The crest elevation is always relative to the upstream node invert elevation NOT the downstream node invert elevaation

Innovyze Strengthens its Business Analytics Asset Performance Modeling Technology with |
|||||
|
Broomfield, Colorado USA, September 13, 2011 — Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced the release of InfoNet Generation V12, its industry-leading asset performance modeling solution. Benefits throughout the latest release include a variety of customer-requested functionalities for improving the management and operation of water, wastewater, and stormwater networks and positively impacting users every day. InfoNet is a purpose-built asset performance modeling and data analysis and management system for water distribution, wastewater collection and stormwater networks. Among its numerous advantages, the software enables users to manage, integrate, validate, analyze and report on their network data to provide accurate, up-to-date, auditable information on network infrastructure and performance in formats that are easy to use and comprehend. InfoNet ensures informed, swift and cost-effective decision making for both day-to-day operational management and long-term network planning. It also enables users to integrate a host of different applications and data sets they already use, including generic GIS, corporate databases, maintenance management systems, field data systems, SCADA, hydraulic modeling/analysis software and other corporate applications. This integration helps them ensure that managers have a single clear picture of their network infrastructures. The software can also directly integrate to the Esri (Redlands, CA) ArcGIS (9.x-10) platform. InfoNet gives engineers the ability to analyze all aspects of the network life cycle. Users can call on its robust query engine to filter, sort, and make complex selections based on virtually any criteria related to their underground assets. It also has the unique ability to query against field surveys (CCTV, manhole inspections, smoke testing, valve inspections, etc.) and other events related to network assets. The InfoNet geospatial environment also lets the user create vivid thematic maps with flexible symbology and rich detail. Its built-in report generator comes with dozens of standard reports and allows users to quickly build custom reports and graphs against any piece of data stored in the system. InfoNet V12 better supports the asset performance modeling of storm water networks with the addition of object types for storage areas and outlets. In addition, it now supports a specific connection pipe object to demonstrate connections between properties or system inlets to the main network. As water systems continue to embrace more proactive maintenance and leak detection programs, InfoNet has added the functionality to support hydrant maintenance activities and leak detection surveys. With these objects, users import or connect to the data from their field systems directly to InfoNet for analysis and performance assessment. CCTV survey support has been modified with updates to the United States PACP standard and the additional of the New Zealand Water and Wastes Association defect scoring standards. A new object entitled Asset Name Groups has also been added. It allows different naming schemes for assets within a network, since assets may be known by different names in different contexts. For example, a building project may have plans that number assets using a completely different naming scheme from that used in the InfoNet database. Asset Name Groups are used to map IDs associated with local naming schemes to the object IDs used in the InfoNet database. Integration with the Esri ArcGIS platform makes it easier for users to build and integrate their modeling results into their enterprise environments. The new version includes options to use ArcGIS Server map services to display background map layers and ArcEngine map controls for offline viewing of background layers. There is also additional support for ArcGIS 10 datasets. For a complete listing of new features, visit the “What’s New” section of the online help for InfoNet V12. |
