Interceptor Design Challenges Working Around Buried Utilities

Speakers: Chris Brooks, P.E., Senior Project Manager, and Amanda Gentry, EIT, Engineer II, RJN Group Inc.

 

Large-diameter gravity sewer interceptor design presents a variety of challenges for the design engineer, the greatest of which is working around buried utilities. This process becomes more difficult every year due to aging infrastructure, urbanization, community revitalization efforts, and unforeseen things like the natural gas exploration (fracking) boom in Dallas-Fort Worth. Unfortunately, information about these high-pressure gas lines can be uncertain, difficult to find or unavailable due to industry mergers and other circumstances. All of this makes utility coordination of sewer designs even more challenging and poses significant liability issues for the design engineer ultimately responsible for designing around or relocating these valuable gas mains. This presentation will discuss real-world examples of how such underground conflicts can be managed, mitigated or avoided.
