Town of Reading, MA, Adopts InfoMaster Smart Asset Management Solution
Innovyze Software to Help Optimize Rehabilitation, Decrease Operational Costs, Improve Efficiency and Extend Lifespan of Critical Assets
Broomfield, Colorado, USA, January 20, 2015 — Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced that the Town of Reading, Massachusetts, has chosen industry-leading InfoMaster Sewer software to help plan and manage its sewer collection infrastructure improvement program. The decision helps the utility leverage its investment in ArcGIS technology from Esri (Redlands, CA) by enhancing it with the most technologically advanced GIS-centric software platform available for collection system capital planning and renewal.


Located just 12 miles from the center of Boston and noted for its award-winning schools, the Town of Reading is responsible for maintaining and operating a municipal wastewater collection system comprising 100 miles of sewer mains and 12 pumping stations. It plans to use InfoMaster and InfoSWMM to create fully prioritized short- and long-term sewer main rehabilitation, replacement, maintenance and management plans and develop sound, cost-effective capital programs to support them.


“The combination of InfoMaster Sewer and InfoSWMM gives us a powerful risk-based asset management solution that will help us assess the condition and performance of our sewer assets more accurately than ever before,” said George J. Zambouras, P.E., Town Engineer. “It also gives us the critical information we need to prioritize and optimize our capital planning expenditures with a focus on solving our most critical sewer infrastructure problems, improving system performance, meeting regulatory compliance, and best serving our customers.”


Many of the world’s wastewater collection systems are reaching or have exceeded their design lives and urgently need extensive upgrading through rehabilitation, repair, and/or replacement. As aging systems deteriorate, they become increasingly vulnerable to structural failures and are plagued by excessive leaks, drops in carrying capacity, poor water quality, and service disruptions. Age-related infrastructure failures are often unexpected and catastrophic, resulting in significant service disruptions, flooding, and local area damage. The only financially responsible solution is to create well-engineered, risk-based capital improvement plans.


Certified by NASSCO PACP, MACP and LACP V6.0, InfoMaster Sewer is the leading software choice for utilities faced with creating such plans, optimizing their infrastructures, and keeping them operating well into the future. It allows utilities to plan system improvements by scoring both the probability and consequence of failure for each underground asset. The assets that have the greatest likelihood of failure and the greatest consequences associated with the failure will be the most critical. Probability of failure is determined based on the pipe’s physical condition and location as well as its hydraulic performance characteristics. Consequence of failure ranking draws on such data as service to critical facilities, total flow carried, population served, adjacent vehicular traffic and other related geospatial factors. Assets that affect system operation normally rate high on the consequence scale, while assets in poor condition have a high probability of failure.


With InfoMaster Sewer, a utility can manage its entire underground infrastructure directly from the Esri geodatabase to deliver unmatched engineering productivity and network performance. Because any analysis is only as strong as its underlying data, InfoMaster Sewer includes direct support for gravity pipes, force mains, manholes, laterals, pump stations, closed circuit television (CCTV) inspections, manhole inspections, smoke testing, customer incidents, and other field activities. Data can be read directly from an enterprise geodatabase; imported or linked to third-party ERP systems; or entered directly through the desktop, Web, or companion smartphone or tablet applications.


“Strong asset performance modeling and capital planning capabilities are critical components of a smart enterprise asset management strategy,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “InfoMaster delivers detailed and accurate analyses and reports that help utility managers make better decisions on when to repair, replace, or rehabilitate their critical assets. It also supports them in developing reliable long-term funding strategies for such projects. These advantages help utilities ensure the long-term sustainability of their infrastructures and their ongoing ability to deliver the required level of service at the lowest lifecycle cost. Innovyze is proud to be a part of Reading’s success as a key component of this complex synthesis.”

Innovyze Unveils InfoSWMM Sustain for Comprehensive Urban Stormwater Treatment and Analysis
New Software Lets Stormwater Management Professionals Determine Optimal BMP Combinations at Various Watershed Scales Based on Cost and Effectiveness
Broomfield, Colorado, USA, January 6, 2014 — Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the second quarter 2015 release ofInfoSWMM Sustain. Designed in response to the needs of watershed and stormwater engineering professionals, this power tool lets users develop, evaluate, and select optimal best management practice (BMP) combinations at various watershed scales on the basis of cost and effectiveness.

InfoSWMM Sustain is a comprehensive geocentric decision support system created to facilitate optimal selection and placement of BMPs and low impact development (LID) techniques at strategic locations in urban watersheds. It can accurately model any combination of LID controls, such as porous permeable pavement, rain gardens, green roofs, street planters, rain barrels, infiltration trenches, and vegetative swales, to determine their effectiveness in managing stormwater and combined sewer overflows. Such capabilities can greatly assist users in developing cost-effective and reliable implementation plans for flow and pollution control aimed at protecting source waters and meeting water quality goals. It does so by helping users answer the following questions: How effective are BMPs in reducing runoff and pollutant loadings? What are the most cost-effective solutions for meeting water quality and quantity objectives? And where, what type, and how extensive should BMPs be?

By seamlessly integrating ArcGIS 10.x with SWMM 5.1, InfoSWMM Sustain greatly expands on the USEPA SUSTAIN software to provide critically needed support to watershed practitioners at all levels in developing stormwater management evaluations and cost optimizations to meet their program needs. The software can automatically import any SWMM5.1, InfoSWMM or InfoWorks ICM model, then evaluate numerous potential combinations of BMPs to determine the optimal combination to meet specified objectives such as runoff volume or pollutant loading reductions. Both kinematic wave and full dynamic wave flow routing models are fully supported. Among its many vital applications, InfoSWMM Sustain can be effectively used in developing TMDL implementation plans, identifying management practices to achieve pollutant reductions under a separate municipal storm sewer system (MS4) stormwater permit, determining optimal green infrastructure strategies for reducing volume and peak flows to combined sewer systems, evaluating the benefits of distributed green infrastructure implementation on water quantity and quality in urban streams, and developing a phased BMP installation plan using cost effectiveness curves.

“With InfoSWMM Sustain, we are extending our success in the smart network modeling marketplace to address the specific needs of stormwater management professionals and their engineering consultants,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “It performs sophisticated hydrologic and water quality modeling in watersheds and urban streams, and enables users to determine optimal management solutions at multiple-scale watersheds to achieve desired water quality objectives based on cost effectiveness. It also gives users the power tool they need to maximize water quality benefits, minimize stormwater management costs and combined sewer overflows, and protect the environment and public health.”

What does Percent Not Converging Mean in SWMM5?

In SWMM 5 there is a Routing time step summary which tells the modeler the minimum time step during the simulation based on the CFL condition, the average time step, maximum time step, the percent of time spent in steady state, the average iterations per step and the percent not converging.  The percent not converging means the percent of the time the link flows and node depths did not converge within the maximum number of trials per time step (Figure 1).

  *************************
  Routing Time Step Summary
  *************************
  Minimum Time Step           :     0.52 sec  
  Average Time Step           :     8.76 sec
  Maximum Time Step           :    10.00 sec
  Percent in Steady State     :     0.00
  Average Iterations per Step :     2.14
  Percent Not Converging      :     1.69

Figure 1.  Maximum number of trials per time step
The Percent Non Converging is the percent of time at least ONE link did not converge within the maximum number of trials per time step.  The Percent Non Converging is the Total Number of Non Convergent Steps divided by the total number of steps during the simulation.

Here is how the converging and non converging is determined in the dynamic wave solution.

The program keeps iterating until the Steps taken during this time step equals the Number of Maximum Trials. During each time step the link flows and the node depths are calculated.  If the Steps are greater than 1 and all nodes depths are converged (the difference between successive iterations is less than the Head tolerance) then the iteration process stops.  If even one node does not converge the Non Converge Count increases by one.   The links that can be bypassed during the next step are also estimated at each iteration. If a link can be bypassed the dynamic wave calculations are not performed and the program runs faster (Figure 2).
Figure 2.  Link Bypass is based on the Upstream and Downstream Nodes

    // --- keep iterating until convergence 
    while ( Steps < MaxTrials )
    {
        // --- execute a routing step & check for nodal convergence
   initNodeStates();
   findLinkFlows(tStep);
   converged = findNodeDepths(tStep);
        Steps++;
        if ( Steps > 1 )
        {
            if ( converged ) break;

            // --- check if link calculations can be skipped in next step
            findBypassedLinks();
        }
    }
    if ( !converged ) NonConvergeCount++;

    //  --- identify any capacity-limited conduits
    findLimitedLinks();

Innovyze Retires InfoWorks SD in Favor of More Powerful Next-Generation InfoWorks ICM Collection Systems Modeling Software
InfoWorks ICM Poised to Dominate Storm Sewer Systems Modeling and Management for Next Decade and Beyond
Broomfield, Colorado, USA, December 30, 2014 — Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced it has retired its InfoWorks SD software, which is being succeeded by the more powerful, next-generation InfoWorks ICM. Current users may continue to use and receive support for InfoWorks SD until December 30, 2015.

Since its initial release in 2010 (three years after the introduction of InfoWorks SD), InfoWorks ICM has rapidly become the solution of choice for collection systems modeling by utilities, municipalities, local authorities cities, stormwater agencies, and their engineering consultants around the world. A fully-dynamic collection system modeling solution, InfoWorks ICM uses a fast, accurate and unconditionally stable implicit numerical solution scheme — delivering a high degree of confidence in simulation results. It can be effectively used to model any complex sanitary, storm and combined sewer system, offering complete hydrology, hydraulic and water quality simulation and sophisticated real-time control (RTC) modeling capabilities. A significantly more powerful version ofInfoWorks SDInfoWorks ICM automates many user-intensive operations, helping engineers minimize time spent creating, calibrating and simulating reliable storm sewer models and analyzing results.

A hallmark of InfoWorks ICM (Integrated Catchment Modeling) is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in rivers, open channels and pipe networks and two-dimensional (2D) hydrodynamic simulation of surface flooding in the urban environment and river floodplain. The combination, achieved through a coupling of 1D and 2D flow equations, provides a powerful solution for simultaneously modeling belowground and aboveground elements of catchments to accurately represent all flow paths and improve understanding of processes occurring in the holistic environment. The software also takes interactions of natural and man-made environments into account, and effectively simulates the impact of polluting runoff and effluent from urban areas on water quality.

“Innovyze is committed to providing the best possible products and quality support for its users,” said Mohamed Abdillahi, UK Director of Product Development. “InfoWorks ICM is by far the best collection systems modeling software we’ve ever developed for the workgroup management platform. Our product philosophy is quite simply to make bold intellectual investments in superior technologies and to consistently adapt to our customers’ changing needs. Only in this way can we continue to best serve our customers and society for the greater good.”

Commented J. Erick Heath, P.E., Vice President and Americas Business Director, “Innovyze has a rich history of introducing the most powerful and comprehensive dynamic sewer modeling software to the global wastewater and stormwater community, and InfoWorks ICM is the crowning achievement in that long series. Starting with WASSPin 1983 and continuing with Wallrus (1989), SPIDA (1991), HydroWorks (1994), InfoWorks CS (1998),InfoWorks SD (2007), to InfoWorks ICM (2010). We are committed to maintaining the momentum of these cutting edge technology introductions to help our customers meet the evolving challenges of the future. It is all about making Innovyze not only the best in the industry but the best for the industry.”

InfoWorks SD was developed as a special version of InfoWorks CS for storm sewer systems modeling. It did not include sanitary flow modeling but featured powerful 2D surface flow modeling capability as an option. CurrentInfoWorks SD users will greatly benefit from an improved interface and enhanced visualization and reporting tools (e.g., undo/redo, recycle bin, no admin program, customized property sheet, dockable Windows and themes). Other significant advantages include substantially faster simulation run times with full 64 bit multi-core processing support; additional important modeling and simulation capabilities; an enhanced database; version control and complete scenario management; multivariable themes and mapping; and stunning graphics. These advanced capabilities make it easier for users to set up, visualize and manage simulations and arrive at fast, reliable solutions to support cost-effective storm sewer systems design, operation and management.
