From Emergency Fix to Future Planning: How SiteMap® Delivers Long-Term Sewer Infrastructure Insight
A Nashville restaurant faced repeated sewer backups with no clear explanation. Without accurate infrastructure records or as-builts, the facility was left vulnerable to health code violations and potential closure. What they needed wasn’t just a quick fix – they needed verified data, actionable insights, and a long-term solution.
The path forward began with GPRS in the field and SiteMap® in the cloud – working together to uncover the problem and deliver lasting insight.
Turning Uncertainty into Insight with Field-Verified Data
GPRS Video Pipe Inspection (VPI) Project Manager Alec Bacon led the investigation, beginning with a methodical inspection of the restaurant’s internal cleanouts.
“They were having issues with the sewer backing up in different spots, and actually suspected that during the building process, someone decided to tie the sewer into the storm drain,” Bacon explained.

Using a push camera, Bacon conducted a visual inspection and began mapping the sewer lines. This technology is essential for navigating smaller-diameter pipes where the CCTV crawler camera can’t operate. The dishwasher room and parking garage cleanouts showed no signs of blockage – the office cleanout told a different story.

Discovering an Illegal Sewer-Storm Drain Tie-In
As the push camera advanced through the PVC line in the office, it revealed a critical issue: the sanitary sewer line was discharging into a concrete storm drain – a serious code violation. To confirm the finding, Bacon deployed a CCTV crawler camera into the storm drain to visually locate the push camera from the sewer line.
“I was able to go into the storm line with the crawler camera, and yep, there’s the push camera hanging out into the storm line,” Bacon said.
To further validate the connection, a dye test was performed. Green dye introduced into the office cleanout was observed entering the storm drain, confirming the illegal tie-in.

From Field Discovery to Digital Records with SiteMap®
GPRS quickly mobilized to deliver a complete, field-verified map of the restaurant’s sewer system. This enabled the restaurant owners to take immediate action to resolve the backups.
GPRS didn’t stop at identifying the sewer-to-storm drain connection. They also marked each cleanout route on-site and delivered a digital map via SiteMap – ensuring the findings were accessible, shareable, and ready to support future planning and compliance.
“It was a really cool example of our services working exactly as they needed to, and the customer was thrilled,” Bacon shared.
Why Interactive Infrastructure Records Matter
Modern infrastructure management demands more than static maps or scattered documents. It requires a centralized, dynamic solution that transforms verified field data into actionable intelligence. SiteMap delivers exactly that – converting GPRS records into a cloud-based platform that empowers smarter, faster decision-making.
