Large sewer system studies have historically required the gathering and management of large quantities of field investigation data. Recent technology has been used to efficiently gather and analyze this data. Digital technologies utilized by RJN Group on several large sewer system studies include the following:

Scanable field inspection forms

Direct digital capture of television inspection data in the field

GPS survey of manhole/structure X,Y,Z location

In addition, technologies for digitally aided data analysis have included:

Utilization of existing digital land base/sewer data

Data exchange between hydraulic modeling and field inspection data

Case study examples from recent large sewer system studies conducted in Dallas, Arlington, Fort Worth and Austin, Texas, and Burlington, Iowa are presented.
