Industry-Leading InfoWater and CapPlan to Support Optimization and Rehabilitation 

 

Broomfield, Colorado USA, October 9, 2012 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced that the City of Santa Monica, California, has selected the company’s industry-leading InfoWater and CapPlan to better manage and strengthen its capital improvement plan. The purchase equips the City’s Water Division with high-performance modeling and asset integrity management and condition assessment tools for assessing and optimizing its water infrastructure.

In order to meet water demand of approximately 13.4 million gallons per day, the City of Santa Monica Water Division supplies water to approximately 90,000 customers through 17,000 service connections, 4,500 valves, and 236 miles of pipes, and operates and maintains 11 water wells, and multiple storage reservoirs and treatment facilities.

“CapPlan Water  gives us the tools we need to prioritize and optimize rehabilitation for our water network,” said Ivo Nkwenji, Lead Systems Analyst for the Division. “In conjunction with InfoWater, this software equips us with a complete solution that will allow us to improve productivity and performance, strengthen our system and deliver significant benefits to our customers.”

The innovative InfoWater smart network modeling technology addresses every facet of utility infrastructure management, optimization and protection. Built atop ArcGIS, (Esri, Redlands, CA), and drawing on the most advanced numerical computation and object-component geospatial technologies, it effortlessly reads GIS datasets and other vital utility systems; corrects network topology problems and data flaws; extracts pertinent modeling information; and automatically constructs, skeletonizes, loads, calibrates and generates optimized solutions with astounding speed. The result is performance modeling that sets new levels of scalability, reliability, functionality and flexibility within the powerful ArcGIS environment.

Using these advanced tools, utilities can easily simulate and evaluate various conditions, pinpoint system deficiencies, and determine the most cost-effective improvements to achieve optimum performance, ensure regulatory compliance, and meet new security challenges.

CapPlan raises the bar for advanced business analytics solutions for water supply and distribution systems. Running on Innovyze’s industry-leading GIS-centric InfoWater package, CapPlan changes the way water utilities plan the relative phasing of system improvements by allowing them to assess and score both the probability and consequence of failure for each asset and identify the worst-performing ones. Assets that affect system operation will normally rate (score) high on the consequence scale, while assets in poor condition will have a high probability (score) of failure.

“We’re very proud to add the City of Santa Monica to the extensive list of California utilities that have adopted our software solutions,” said J. Erick Heath, P.E., Innovyze Vice President and Director of Americas Operations. “The City’s decision to implement CapPlan and InfoWater is a strong testament to the software’s unsurpassed power to assist utilities in determining the most cost-effective operational and physical improvements, while still meeting budgetary goals and strategic plans. We’re delighted to have been given the opportunity to contribute to their success.”

Lambda Calculus and Link Variables in the InfoSWMM, H2OMAP SWMM and SWMM 5 Dynamic Wave Solution

Subject:  Lambda Calculus and Link Variables in the InfoSWMM, H2OMAP SWMM and SWMM 5 Dynamic Wave Solution


SWMM 5 uses the method of Successive under-relaxation to solve the Node Continuity Equation and the Link Momentum/Continuity Equation for a time step.  The dynamic wave solution in dynwave.c will use up to 8 iterations to reach convergence before moving onto the next time step.  The differences between the link flows and node depths are typically small (in a non pumping system) and normally converge within a few iterations unless you are using too large a time step.  The number of iterations is a minimum of two with the 1st iteration NOT using the under-relaxation parameter omega. The solution method can be term successive approximation, fixed iteration or Picard Iteration, fixed-point combinatory, iterated function and Lambda Calculus. In computer science, iterated functions occur as a special case of recursive functions, which in turn anchor the study of such broad topics as lambda calculus, or narrower ones, such as the denotational semantics  of computer programs (http://en.wikipedia.org/wiki/Iterated_function). 


In the SWMM 5 application of this various named iteration process there are three main concepts for starting, iterating and stopping the iteration process during one time step:


·         The 1st guess of the new node depth or link flow is the current link flow (Figure 3) and the new estimated node depths and link flows are used at each iteration to estimate the new time step depth or flow.  For example, in the node depth (H) equation dH/dt = dQ/A the value of dQ or the change in flow and the value of A or Area is updated at each iteration based on the last iteration’s value of all node depths and link flows.  


·         A bound or a bracket on each node depth or link flow iteration value is used by averaging the last iteration value with the new iteration value.  This places a boundary on how fast a node depth or link flow can change per iteration – it is always ½ of the change during the iteration (Figure 1).  


·         The Stopping Tolerance (Figure 2) determines how many iterations it takes to reach convergence and move out of the iteration process for this time step to the next time step.


Figure 1.  Under relaxation with an omega value of ½ is done on iterations 2 through a possible 8 in SWMM 5. This is not done for iteration 1.


Figure 2.  if the change in the Node Depth is less than the stopping tolerance in SWMM 5 the node is considered converged.  The stopping tolerance has a default value of 0.005 feet in SWMM 5.0.022. 




Figure 3.  The differences between the link flows and node depths are typically small (in a non pumping system) and normally converge within a few iterations unless you are using too large a time step.  The number of iterations is a minimum of two with the 1st iteration NOT using the under-relaxation parameter omega.


St. Venant equation – this is the link attribute data used when the St. Venant Equation is used inSWMM 5, H2OMAP SWMM and InfoSWMM.  Simulated Parameters from the upstream, midpoint and downstream sections of the link are used.

Normal Flow Equation – this is the link attribute data used when the Normal Flow Equation is used in H2OMAP SWMM. Only simulated parameters from the upstream end of the link are used if the normal flow equation is used for the time step.  The normal flow equation is used if the flow is supercritical or the water surface slope is less than the bed slope of the link.
