H2S Modeling in an InfoSWMM Pond

The control of odorous gases and the corrosion of sewers are the two most important problems in operating wastewater collection systems.  H2S is the most commonly known and prevalent odorous gas associated with domestic wastewater collection and treatment systems.  InfoSewer. InfoSWMM, H2OMap SWMM or H2OMAP Sewer suite gives wastewater engineers a powerful Operations and Maintenance (O&M) tool to readily model and analyze entire sewer collection systems for sulfide generation and corrosion potential under varying conditions anticipated throughout the life of their systems. H2S  predicts sulfide buildup in sewer collection systems for gravity sewers, force mains, and wet wells using the Pomeroy-Parkhurst equations. This unique and powerful tool enables wastewater utilities to pinpoint odor and corrosion problems, develop effective monitoring programs, alert plant operators and sewer maintenance workers to potential danger and the need to observe safety practices, and evaluate and implement effective control system such as aeration, chlorination, and mechanical cleaning.
Modeling of hydrogen sulfide using H2S Detector requires minimal input data from the user. The required data include:
Lightning average daily temperature for the region (in degrees C).
Lightning reaction rate coefficient (per day) which was described above in relation to BOD modeling.
Lightning pH of the wastewater. The normal pH range of municipal wastewater is 6.0 to 8.0.
Lightning effective sulfide flux coefficient  for sulfide generation by the slime layer in gravity sewers (meter/hour). For conservative analysis (i.e., observed sulfide buildup generally less than predicted), the suggested values of this parameter is 0.00032.
Lightning a dimensionless coefficient to account for sulfide losses by oxidation and escape to atmosphere. For conservative analysis (i.e., observed sulfide buildup generally less than predicted), the suggested values of this parameter is 0.64. For moderately conservative analysis a value of 0.96 is suggested.
Lightning logarithmic ionization constant for hydrogen sulfide (unit less), a function of temperature and specific electrical conductance of the waste water. Its value generally varies from 6.67 (at a temperature of 40oC and specific electrical conductance of 50, 000 micromhos/cm) to 7.74 (at a temperature of 10oC and specific electrical conductance of 0 micromhos/cm).
Lightning percent of total sulfides that occur in the soluble (dissolved) form for the wastewater, most frequently known to vary from 70 to 90 percent.
The default values used by the model for these inputs are shown in the following dialog box. In addition to the listed data, the user has to supply initial concentration of total sulfides and ultimate BOD of  the wastewater. These two variables could be assigned using the quality tab available at the top of the attribute browser, for one source node at a time, or using the " Group Edit on Domain" feature that enables simultaneous assignment of the two variables for all source nodes in the domain.

Simulation Task Manager in InfoSWMM and H2OMap SWMM

Several factors can effect the processing time needed to run simulations of sewer networks including computer hardware, simulation timestep, reporting timestep, size of the network, length of simulation, sophistication of the simulation (e.g. controls, 2D) etc. Even though our products utilize the most robust solution engines possible, simulations can take a while to complete. Simulation Task Manager allows you to disconnect the simulation of modeling scenarios from other modeling work so that you can be more productive while simulations are running.

Simulation Task Manager allows you to:
  1. Start, pause and delete scheduled simulations 
  2. View summary and detailed information about each scheduled simulation 
  3. Continue to process simulation tasks without the model open that scheduled the simulation
Using Simulation Task Manager will greatly enhance your ability to be productive when working with simulations that take a long time to complete. This technical advancement once again shows the dedication of Innovyze(R) Inc. to providing the best and most advanced tools possible to modeling professionals.

Please note: This help file applies to both InfoSWMM and H2OMap SWMM which share the same underlying engine and graphics.

lnnovyze lnfoSWMM® is an Esri ArcMap Extension and H20MAP SWMM® is a standalone program, both of which use the same USEPA SWMM5 engine. They also work from a set of Dynamic Link Libraries (DLLs) that reside in the Windows Program Files folder. As a common method to process files, the DLL'S work with various Graphic User Interface(GUI) components so several applications may utilize the same functionality. Therefore, while the GUls for lnfoSWMM and H20MAP SWMM are different, both programs use the same Database drivers and Dynamic Link Libraries (DLLs) to produce results. This ensures you receive identical output across lnfoSWMM and H20MAP SWMM because the underlying Database, Computational Engine and Results DLL program files are identical.

InfoSWMM Now Supports EPA SWMM-CAT, Enabling Modeling of Future Climate Change Projections
Direct Support to SWMM-CAT Power Communities in Assessing Impact of Future Changes in Climatic Conditions and Helping to Build Safer, Sustainable, More Resilient Water Infrastructure
Broomfield, Colorado, USA, June 9, 2015 — In its ongoing quest to equip the water industry with the world’s most comprehensive and innovative smart network modeling and management solutions, Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced that InfoSWMM (and H2OMAP SWMM) now fully support the newly released USEPA Storm Water Management Model Climate Adjustment Tool (SWMM-CAT). This important capability allows users of InfoSWMM (and H2OMAP SWMM) to directly estimate future changes in temperature, evaporation and rainfall for simulation modeling.

The SWMM-CAT tool provides a set of location-specific adjustments derived from global climate change models run as part of the World Climate Research Programme (WCRP) Coupled Model Intercomparison Project Phase 3 (CMIP3) archive. These are the same climate change simulations that helped inform the United Nations Intergovernmental Panel on Climate Change in preparing its Fourth Assessment report. SWMM-CAT and the USEPA Stormwater Calculator for Low Impact Development simulation are both part of the President’s Climate Action Plan.

Built atop ArcGIS (Esri, Redlands, CA), the full-featured InfoSWMM analysis and design program delivers the highest rate of return in the industry. All operations of a typical sewer system — from analysis and design to management functions such as water quality assessment, pollution prediction, sediment transport and deposition, urban flooding, real-time control, and record keeping — are addressed in a single, fully integrated geoengineering environment. The program’s powerful hydraulic and water quality computational engine is based on the latest SWMM 5.1 version, which is endorsed by the USEPA and certified by FEMA. These features and more deliver an enhanced modeling experience and greater realism of displayed results — advantages that translate to increased productivity, reduced costs, higher accuracy, better efficiency, and improved designs.

InfoSWMM also serves as a robust base platform for advanced modeling, operational, short-term and long range planning, capital planning, urban stormwater treatment and analysis, and analytics-driven asset management extensions. Some of these critical applications include InfoSWMM 2D (two-dimensional surface flood modeling),CapPlan (risk-based capital planning and asset performance modeling), InfoSWMM Sustain (optimal selection and placement of LIDs/BMPs), InfoSWMM SFEM (dynamic sewer flow estimation model), InfoMaster (GIS-centric analytics-driven asset management), and RDII Analyst (rainfall-dependent inflow and infiltration planning and analysis).

“Our priorities have always been to advance the frontiers of smart network modeling technology and support our customers’ successes by helping them better prepare for climate impacts and build safer, better water infrastructures,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, Dist.M.ASCE, NAE, President, COO and Chief Technical Officer of Innovyze. “This direct support to the EPA Storm Water Management Model Climate Adjustment Tool delivers on our promise to equip our customers with the ultimate geospatial decision support tool for evaluating, addressing and managing climate change risks for more resilient, sustainable sewer collection and urban drainage systems.”

Manhole Elevations in InfoSWMM and SWMM 5

Manhole Elevations in InfoSWMM and SWMM 5
Subject: Manhole Elevations in InfoSWMM and SWMM 5
Starting from the bottom of the manhole you have these regions of computational interest:
1.   Manhole Invert to the lowest link invert – the node continuity equation is used with the area of the manhole being the default surface area of a manhole,
2.   Lowest Link Invert to the Highest Link Crown Elevation – the node continuity equation is used with surface of the node being normally half of the surface area of the incoming and outgoing links,
3.   Highest Manhole Pipe Crown Elevation to Manhole Rim Elevation – the node surcharge algorithm in which the surface area of the manhole is not used and the surcharge depth is iterated until the inflow and the outflows of the node are in balance,
4.   The region above the Manhole Rim Elevation which can use one of four options to calculate the depth and/or flow out of or into the manhole:
1.   No Surcharge Depth is entered and No Ponding area is used – the excess water into the manhole is lost to the network and shows up as internal outflow in the continuity tables,
2.   A Ponding Area is used and the excess flow will  pond on the surface of the manhole and later go back down into the conveyance pipes.
3.   A Surcharge Depth is used and the depth will continue to be calculated using the node surcharge algorithm in which the surface area of the manhole is not used and the surcharge depth is iterated until the inflow and the outflows of the node are in balance,
4.   A Dual Drainage system is simulated and the excess flow of the manhole is simulated in the street gutters or the actual street,
5.   You use a 1D/2D linkage between the 1D manhole and 1D links to a 2D Mesh and simulate the flow out and the flow into the manhole using a bottom outlet orifice that switches automatically between weir and orifice flow based on the depth on top of the manhole.

2014 - That was fun - an update of an announcement from the past.  The original is on our website. I changed my name from Bob to Robert, the company name from MWHSoft to Innovyze and list my my actual job or jobs I have been doing at @Innovyze from 2008.  I left the title alone - sometimes it is best to have a goal in life and trying to achieve the title of the announcement is something I would like to approach in my remaining Innovyze years.  I probably will not reach it but I appreciate the mastery of the Paul Boulos announcements - he writes the most creative and wonderful press releases. You should subscribe to them from www.innovyze.com if you want to read about the future of water, sewer and stormwater.  A final mention of Alight Tsai who manages http://www.innovyze.com/ and is always helpful with great images for our software and help files.  I would be remiss if I did not mention our great R/D product development teams in Monrovia and Wallingford. I am proud to be a small part of the Monrovia team.  Other history mentions about SWMM3/4/5 in my past can be found here http://www.swmm5.net/2012/05/my-history-with-various-versions-of.html
