Broomfield, Colorado USA, July 25, 2012 — In its ongoing quest to equip the wastewater 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 wet infrastructure, today announced the worldwide availability of the V12 Generation of its industry-leading InfoSWMM for ArcGIS (Esri, Redlands, CA). InfoSWMM V12 enables engineers to work more efficiently and reliably with very large and complex network models, thanks to improvements in such areas as HEC-22 inlet support, built-in 64-bit simulation, enhanced water quality modeling, and batch run scenario management that will positively impact modeling teams each and every day. The only urban drainage modeling solution certified by the National Association of GIS-centric Software, 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 current SWMM 5 version, which is endorsed by the USEPA and certified by FEMA. These features and more result in 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, capital planning, 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),InfoMaster (GIS-centric asset management), and RDII Analyst (rainfall-dependent inflow and infiltration planning and analysis). The release of InfoSWMM V12 extends previous generations’ capabilities with significant modeling enhancements and groundbreaking innovations in geoengineering productivity and efficiency. These improvements greatly simplify, accelerate, and integrate urban drainage network engineering, helping wastewater engineers develop better designs and operational improvements faster. Key new built-in modeling and computational tools include:
“Our priorities have always been to advance the frontiers of smart network modeling technology and support our customers’ successes by helping them be more productive and competitive,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “This major InfoSWMMrelease delivers on our promise to equip our customers with the ultimate ArcGIS-centric decision support tool for sewer collection and urban drainage systems. Like its predecessors, InfoSWMM V12 sets a new standard for quality and high-performance network modeling and management with unrivaled power, cutting-edge capabilities, rich functionality, and ease of use. From top to bottom, this release is designed for record modeling performance that enables users to increase their productivity and quality while achieving their engineering and business goals.” |

Subject: SWMM 5 Controls or Real Time Controls
Possible SWMM 5 Controls are shown in Figure 1 along with how the Rules are interpreted in Figure 2.

Subject: What Does Error 159 Mean in SWMM 5? If you get error 159 or a Rain Gage Interval Error it means rain gage
interval is greater than the gage interval in your time series or most
likely you have duplicate data times in the time series. // --- check gage's recording interval against that of time series gageInterval = (int)(floor(Tseries[k].dxMin*SECperDAY + 0.5)); if ( gageInterval > 0 && Gage[j].rainInterval > gageInterval ) { report_writeErrorMsg(ERR_RAIN_GAGE_INTERVAL, Gage[j].ID);

Subject: How Does a TYPE1 Pump Work in SWMM 5?
A SWMM 5 Type1 pump is called an offline pump but the name comes from SWMM 4 and the Pump is controlled by volume instead of depth or head as in the SWMM 5 TYPE2, TYPE3 and TYPE4 Pumps. The attached example SWMM 5 model has an offline storage node that pumps flow INTO the Offline Storage unit during high flow and FROM the Offline Storage Unit during low flow. The SWMM 5 Real Time Control (RTC) rules determine which of the two pumps operate based on the flow in an upstream link (Figure 1).

Subject: What are the Types of Force Mains (FM) in SWMM 5?
There are five ways to model a force main in SWMM 5 for the combination of full and partial flow in the force main (Figure 1):
1. Full Flow using Darcy-Weisbach for the friction loss
2. Full Flow using Hazen-Williams for the friction loss
3. Full Flow using Manning’s n for the friction loss
4. Partial Flow uses Manning’s n for the friction loss for Force Main Equation options
If you use Darcy-Weisbach or Hazen-Williams then an equivalent Manning's n for a force main that results in the same normal flow value for a force main flowing full under fully turbulent conditions is calculated internally in SWMM 5 in forcemain.c
· Equivalent n for H-W is 1.067 / Hazen-Williams Coefficient * (Full Depth / Bed Slope) ^ 0.04
· Equivalent n for D-W is (Darcy-Weisbach friction factor/185) * (Full Depth) ^ 1/6
