The City of Denton Wastewater Department in Texas has chosen Innovyze's InfoMaster Sewer software to help manage the replacement and rehabilitation of its underground distribution infrastructure. Accordingly, the decision helps the utility leverage its investment in ArcGIS technology from Esri (Redlands, CA) by enhancing it with an advanced GIS-centric software platform for collection system capital planning and renewal.

Located north of the Dallas-Fort Worth metropolitan area, Denton is one of the 25 fastest-growing cities in the United States. From 2000 to 2010, the city grew by 40 percent and today encompasses a population of 123,000. To serve this burgeoning community, Denton maintains more than 500 miles of wastewater collection mains distributed over four main basins and 33 sub-basins. It also operates its own cleaning and closed circuit television (CCTV) inspection program.
 
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 designed for utilities faced with creating such plans and optimizing their infrastructures, as well as 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 it 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 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 engineering productivity and network performance. Further, InfoMaster Sewer includes direct support for gravity pipes, force mains, manholes, laterals, pump stations, 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.
