How to use the Flow Splitter in InfoSewer for Dendritic Networks

Subject:  How to use the Flow Splitter in InfoSewer for Dendritic Networks  

  InfoSewer, which is an extension in Arc Map, does need to have slit split defined where gravity mains merge together to determine the amount of flow in each of the downstream conduits (Figure 1).   The options for the flow splitter in each of the downstream links are:

 

 1.       Automatic Allocation

2.       Fixed Flow Percentage

3.       Variable Flow Percentage and

4.       Inflow-Outflow Curve 

 

At an outfall where the invert of the outfall pipe is raised compared to the inverts of the incoming and outgoing pipes a flow split of Variable Flow Percentage or Inflow/Outflow curve may work better (Figure 2).

Providence Water to Use InfoWater and InfoWater UDF to Support 17 Cities and Towns in Rhode Island

 

Broomfield, Colorado USA, August 7, 2012 — Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, today announced that Providence Water, the largest water utility in the state of Rhode Island, has selected Innovyze’s industry-leading InfoWater and InfoWater UDF smart water modeling and management solution software to manage its vast hydraulic network. The purchase equips Providence Water with a comprehensive range of high-performance ArcGIS-centric (Esri, Redlands, CA) water infrastructure analysis and management capabilities, enabling the utility to address critical design, operational, and water quality issues with maximum effectiveness while optimizing customer service.

Providence serves 17 cities and towns in Rhode Island, supplying water to 60 percent of the state’s residents. The network comprises 950 miles (1,529 km) of water mains and 5,780 fire hydrants and delivers an average of 62 million gallons of water per day.

“InfoWater and InfoWater UDF not only offer great value in terms of features and functions but also provide reliable and accurate solutions,” said Peter LePage, Senior Manager of Engineering at Providence Water. “These applications enhance our ability to produce excellent water quality and help ensure that we maintain the highest level of customer service to Rhode Island residents.”

InfoWater boasts innovative smart network modeling technology that addresses every facet of utility infrastructure management, optimization, and protection to deliver the highest rate of return in the industry. Operating directly within the powerful ArcGIS environment, InfoWater’s unique interoperable geospatial framework enables world-record performance, scalability, functionality, and reliability.

InfoWater UDF brings unprecedented power and flexibility to the management of systematic flushing of water distribution systems to restore hydraulic capacity, remove sediments and deposits, control corrosion, and, ultimately, prolong the life expectancy of the network.

Together InfoWater and InfoWater UDF make it easy for water utilities to analyze and simulate various conditions, pinpoint system deficiencies, and determine the most cost-effective physical and operational improvements for achieving optimum performance and regulatory compliance.

Rules for NRSCS Unit Hydrographs in InfoSWMM

Subject:  Rules for NRSCS Unit Hydrographs in InfoSWMM

 

Rules or Guidelines for NRSCS Unit Hydrographs if used as the Hydrology Option in InfoSWMM and H2OMAP SWMM:

1.       The Unit Hydrograph CN comes from the Subcatchment Table and the NRCS_CN Column

2.      Time of Concentration is from the TC column in the Subcatchment Table

3.      The Infiltration Model should be from the CN infiltration Model Column in the Subcatchment Database Table

4.      The CN in the Soil Database Table should be the same as the CN in the Subcatchment Database Table

5.      If the Depression Storage is zero in the Subcatchment Database Table then the Initial Abstraction in inches will be calculated as 0.2*(1000/CN-10) internally in the engine

6.      Initial Abstraction or IA in US Units =  0.2*(1000/CN-10) in American Units

San José, California, Looks to Innovyze Solution to Manage Its Wastewater and Stormwater Networks

 
 

Broomfield, Colorado USA, July 31, 2012 — Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced that the City of San José, California, has selected InfoWorks ICM to meet its complex sewerage and stormwater modeling requirements. With this purchase, San Jose gains access to the most advanced and comprehensive collection system modeling and management applications in the industry.

The City of San José serves nearly a million residents and businesses spread out over 178 square miles (461 km2). It owns and operates a sewer collection system consisting of approximately 2,259 miles (3,636 km) of sanitary sewer mains (varying from 6 to 90 inches in diameter), 45,000 manholes, and 15 pump stations. The collected wastewater is conveyed to the city’s Water Pollution Control Plant by major interceptor pipelines located in the northern part of San José.

“San José is committed to continuous improvement of our system and finding the most economical ways to improve its performance,” noted Shelley Guo, P.E., Senior Civil Engineer. “We’ve started using InfoWorks ICM within both our sanitary master planning group and stormwater group to help us achieve this goal.” The City will also see a productivity boost by utilizing the InfoWorks ICM simulation server to run modeling simulations in their data center, freeing up their modeler’s computers for other tasks. 

A hallmark of InfoWorks ICM is its dynamic integration of one-dimensional hydrodynamic simulation of flows in rivers, open channels, and pipe networks with two-dimensional hydrodynamic simulation of surface flooding in the urban environment and river floodplain. This industry-leading software provides a powerful solution for simultaneously modeling belowground and aboveground elements of catchments to accurately represent all flow paths and improve understanding of the processes occurring in the holistic environment. The software also takes into account interactions of natural and man-made environments and effectively simulates the water quality impact of polluting runoff and effluent from urban areas. Such advanced capabilities greatly enhance wastewater utilities’ ability to predict flood risks; support cost-effective drainage design and management; develop online urban flooding forecasts; conceive and evaluate sound and reliable urban catchment strategies such as storm sewer separation, active real-time control, and provision of adequate additional storage; and improve the operation of any drainage system.

A sophisticated tool for importing, tracking, and auditing large amounts of highly complex data, InfoWorks ICM allows the development of cost-effective, innovative solutions to engineering challenges as well as a complete understanding of the processes involved. Multiple simulations can be scheduled across a pool of workstations with results returned to a single location, making for highly effective use of computing resources.

“We are proud to add San José as the latest leading sewer utility to switch to InfoWorks ICM,” said J. Erick Heath, P.E., Innovyze Vice President and Director of Americas Operations. “This vanguard product has proven to be the top choice of collection system engineers charged with planning, designing, operating, and sustaining safe and reliable drainage systems and protecting the public health and our waterways.”
