Peachtree City, GA Adopts InfoSWMM Vanguard Smart Network Modeling Will Improve Management of Sewer Infrastructure Broomfield, Colorado, USA, November 17, 2015 Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced that the Peachtree City Water & Sewerage Authority (PCWASA), Georgia, has chosen Innovyze’s  InfoSWMM , the industry-leading solution for geocentric smart water network modeling. The software will serve as the foundation for the development of a comprehensive ArcGIS-centric (Esri, Redlands, CA) approach to managing the PCWASA sewer system. PCWASA owns and operates two wastewater treatment facilities along with approximately 200 miles of gravity sewer and force main and 35 pumping stations, serving more than 10,000 customers within Peachtree City. The PCWASA geographic service area is approximately 24 square miles. “We chose  InfoSWMM  for its comprehensive sewer modeling and simulat...

Twenty interesting facts about H 2 OMap Sewer and an inverse color Map of the H 2 OMap Sewer Interface (Figure 1).   H 2 OMAP Sewer Sewer is a stand-alone GIS based program for use in the planning, design, analysis, and expansion of sanitary, storm and combined sewer collection systems. It is very good program if you like steady state analysis with peaking factors for manhole loading.

This blog is about using the Advanced Force Main Solution and Gravity Main Attenuation in  InfoSewer  for better Pump, Force Main, Gravity Main Simulations   Select Advanced Force Main Solution and Flow Attenuation the Run Manager The overall Continuity Error will be Better Gravity mains will be closer to the Force Main Flows Force Main Flows will be closer to the Pump flows        Select Advanced Force Main Solution and Flow Attenuation the Run Manager      Force Main Flows will be closer to the Pump flows        The overall Continuity Error will be Better      Gravity mains will be closer to the Force Main Flows Advanced Force Main Solution and Gravity Main Attenuation in  InfoSewer   for better Pump, Force Main, Gravity Main Simulations

See the image for the two main reasons but another reason is that you get a better continuity error with this new(er) feature or option in InfoSewer A Simple Advanced Model in InfoSewer

The image at the bottom shows the rules for Force Mains in InfoSewer and H2OMap Sewer: 1.       Gravity Main 2.      Wet Well 3.      Pump 4.      Chamber Manhole 5.      Force Main  if you have many force mains the node BETWEEN two force mains has to be a Chamber Manhole a.      The error messages for this are now rigorously enforced and they may not  have been in past versions 6.      Loading Manhole 7.      Gravity Main

A few tips for using Hazen Williams and Force Mains in SWMM 5.   A key fact is to remember ONLY one flow in the middle of the link is computed in SWMM 5 so you may have to add Break nodes, use a smaller time step and use a flap gate depending on how often your pumps turn on.  If you do not have numerical problems with the time step you should get exactly the same head loss as you do in steady state Hazen Williams calculators when you use InfoSWMM, H2OMap SWMM and SWMM 5. Figure 1.  Larger Tip Image   Figure 2.  SWMM 5 compares well to the Hazen Williams Head loss calculators

The Equivalent n for Hazen-Williams in a Force Main of SWMM 5 SWMM 5 uses an equivalent Manning's n for the Hazen-Williams Coefficient for partial flow in a force main of SWMM 5.  The equivalent n is a function of the force main diameter, slope and the power equation used by Lew Rossman of the EPA in the SWMM 5 C code in the routine forcemain_getEquivN.   I am also including the C code to print out the HW value, diameter, slope and Equivalent n in the output file.  It is easy to add new of code to SWMM 5 for your thesis as long as you have a compiler (I suggest the current free Visual Studio from Microsoft) and know how to add the fprintf statements.  This simple addition gives you the power to understand more fully the inner working of SWMM 5 and add more content and understanding to your thesis or paper.

Vacuum Sewers Compiled by: Beat Stauffer (seecon international gmbh) Source:   http://www.sswm.info/category/implementation-tools/wastewater-collection/hardware/sewers/vacuum-sewers Executive Summary Vacuum sewerage systems consist of a vacuum station, where the vacuum is generated, the vacuum pipeline system, collection chambers with collection tanks and interface valve units. In contrast to conventional gravity sewerage systems with intermediate pumping stations, the permanent pressure within the vacuum system is maintained below atmospheric pressure. Moreover, vacuum technology reduces water consumption considerably, enabling flexible installations regardless of topography and water availability. In addition, it allows for the use of alternative wastewater handling (blackwater and greywater separation).
