CCTV: The Land Down Under

CCTV

A crew-member monitors closed-circuit TV (CCTV) footage from a van parked at a worksite. CCTV is a cost-effective way to inspect sewer pipes and identify problem areas.

Sewers are one of the most expensive infrastructures to install and rehabilitate. Closed-circuit television (CCTV) cameras are an economical way to monitor pipe conditions and spot blockages before catastrophic events can occur. To get a look, Seattle Public Utilities’ crews deploy specialized CCTVs to investigate pipes and assess the problem. Roots, grease, debris, or maybe a sag in the line may be the problem to a functional sewer pipe.

Departments across the City rely on CCTV inspections to do their work. Civil engineers need footage of the sewer system before they can begin to write plans for new projects. The Source Control team often uses CCTV to verify the existence of cross connections. And, the Fats Oils and Grease (FOG) program depends on CCTV to track and lessen grease buildup.

In addition, when it comes to water quality, so much relies on CCTV. Routine sewer inspections help to find blockages, problem areas, collapsed pipe, and all the other things that get in the way of a sewer pipe functioning property. This way, we can catch and prevent sanitary sewage overflows before they happen. CCTV technology is vital to SPU’s efforts to monitor and maintain Seattle’s 1,400 miles of sewer pipe infrastructure.
