North Carolina City Chooses InfoSewer

ArcGIS Based Sewer Modeling Package Helps Hendersonville, NC Model and Manage Its Collection System

Broomfield, Colorado, USA, January 31, 2012

Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced the City of Hendersonville, North Carolina, has selected InfoSewer for ArcGIS (Esri, Redlands, CA) as its sewer modeling platform. InfoSewer has helped define the standard in the industry for GIS-centric sewer network analysis, planning and design since 2003.

The City of Hendersonville’s Water and Sewer Department is responsible for providing water service to more than 62,000 residents and businesses of Hendersonville and Henderson County and sewer service to more than 19,000 residents and businesses. The Department is also responsible for the operation and maintenance of over 580 miles of water mains, 57 water pumping stations, 24 water storage tanks (ranging in size from 100,000 gallons to 5 million gallons), over 185 miles of sewer mains and 37 sewer pumping stations. “InfoSewer gives us the blend of powerful, easy-to-use analysis capabilities we need to effectively plan and manage our sewer system,” said Brent Detwiler, City Engineer. “We have a significant investment in Esri ArcGIS technology, and InfoSewer lets us leverage our GIS data for fast and accurate modeling.”

Certified by the National Association of GIS-centric Software, InfoSewer is a powerful ArcGIS-based computer program for planning, designing, analyzing, and expanding sanitary, storm and combined sewer collection systems. It can be effectively used to model both dry-weather and wet-weather flows and determine the most cost-effective and reliable method of wastewater collection. Built atop ArcGIS, InfoSewer enables engineers and GIS professionals to work simultaneously on the same integrated platform, commanding powerful GIS analysis and hydraulic modeling in a single environment using a single dataset.

InfoSewer is used worldwide by municipal engineers and planners to create detailed, accurate models of their sewer infrastructure systems. These models enable them to evaluate the effect of new developments, zoning changes, and other additional loads on system flows; pinpoint current and future problem areas; predict overflows and backups; and determine how best to restore needed capacity lost to infiltration and inflow with the least rehabilitation. 

Users also rely on these models to compute hydrogen sulfide generation and corrosion potential; analyze the rate of Biochemical Oxygen Demand (BOD) exertion; track sediment movement and deposition; trace pollutant contribution from source nodes; perform time of concentration calculations; calculate the amount of pollutant transported to the wastewater treatment plant; and assess pollutants’ impacts on receiving waters. Extensive scenario management functionality enables users to analyze existing or future sewage collection systems. The application also provides vital tools for meeting and exceeding environmental regulations and improving community relations via database queries and map displays.

InfoSewer also delivers advanced design functionality and exponential increases in efficiency while simplifying use. Users can quickly and reliably design new sewer collection systems that consider standard design criteria such as flow depth-to-pipe diameter ratios, velocity, slope, soil cover depth, and pipe crown drop. Using user-input manhole locations and rules, InfoSewer calculates the optimal pipe and slope, invert elevation of conduits and manholes, soil cover depths at both ends of each pipe section, and cost of excavation and reinstatement to meet target design criteria. Results can be reviewed using profile plots with advanced labeling of 30 node and link variables, color-coded sewer maps of these variables, or 20 comprehensive tabular reports. The profile plots can be automatically updated in the model database for steady state and extended period simulations of new and existing designs, greatly simplifying the model-building process.

Together, these capabilities help wastewater utilities worldwide dramatically raise productivity and efficiency by rapidly developing practical and optimal capital improvement strategies that minimize costs while improving system reliability, integrity and performance. By making engineering professionals more productive and their organizations more competitive, InfoSewer delivers benefits utilities can pass on to their customers through better designs and higher quality standards, achieved in a shorter turnaround time.

InfoSewer continues to evolve to meet the growing needs of top utilities around the globe,” said Innovyze Americas Operations Director J. Erick Heath, P.E. “We are thrilled that progressive leading utilities like Hendersonville are using InfoSewer to design and manage the most efficient sewer collection systems possible.”
