Woolpert Conducts Stormwater System Evaluation at Indianapolis International Airport

Woolpert used CCTV at the Indianapolis International Airport and discovered stormwater pipes such as this were deformed, causing joints to separate and allowing fill to seep in.

The Indianapolis Airport Authority (IAA) contracted with Woolpert to conduct a stormwater system evaluation to investigate the cause of surface depressions that formed near a large stormwater pipe at the Indianapolis International Airport (IND). Woolpert was on-site discussing projects under the firm’s multiyear on-call aviation engineering contract with IAA when the issue of the depressions was broached.

“The folks in Indy remembered we were performing similar stormwater evaluation work with the (Hartsfield-Jackson International) airport in Atlanta (ATL), and asked us to take a look,” said Richard Washington, Woolpert project manager.

Woolpert employed closed-circuit television (CCTV) at IND and discovered the stormwater pipes were deformed, causing joints to separate and allowing fill to seep in, which caused the depressions.

Woolpert—an international architecture, engineering and geospatial (AEG) firm—is well-versed in Federal Aviation Administration (FAA) rules and regulations, and specializes in a multitude of services that support airports. These include runway design, geographic information systems (GIS), facility sustainability, airspace analyses, wastewater and stormwater management, and asset management.

“At ATL, we’re doing more of a sanitary sewer evaluation, looking at a majority of pipes throughout the airport for general condition assessment and recommending rehabilitation where needed,” Washington said. “We’re using the CCTV there as well to identify blockages and ensure the stormwater lines are clean and free from debris in order to prevent backups and flooding. We’ve been working on that continuously for about four years.”

Washington said routine wastewater and stormwater maintenance can be neglected, since underground infrastructure is out of sight and out of mind. This can lead to significant issues at any site, but these kinds of backups can be especially crucial at airports, where moving passengers safely and quickly is the priority.

“Airports have to adhere to strict schedules and create a pleasurable experience so people will want to choose that airport,” he said. “Asset management and maintenance are needed to prevent sanitary sewer and plumbing issues that can make a guest’s experience very unsatisfactory. People don’t want to visit an airport if they’ve had a bad experience there.”

Woolpert is also working with ATL to update its GIS records for underground infrastructure throughout the airport in support of ATL’s asset management program, to establish a schedule and protocol that will let officials know what pipes need to be looked at and when.

The IAA is in the process of addressing the rehabilitation and replacement of the affected pipes to prevent surface depressions, as well as to identify future underground infrastructure issues.
