Water Authority Wins Golden Watchdog Award
The San Diego County Water Authority won a Golden Watchdog Award at this year’s Golden Watchdog & Fleece Awards hosted by the San Diego County Taxpayers Association on Oct. 18. The Water Authority was recognized for its deployment of “Scanny,” a high-tech surveillance device designed to safely and efficiently monitor the agency’s large-diameter pipelines that provide water to the San Diego region.

A special congratulations to the Water Authority’s Operations and Maintenance team and in particular Asset Management Manager Martin Coghill, who designed and patented “Scanny” on behalf of the Water Authority.
Proactive maintenance and asset management practices allow water agencies to extend the lifespan of their pipeline assets by more than 50%. With 308 miles of transmission pipelines, 100 flow control facilities and more than 1,400 pipeline-related structures, the Water Authority is constantly assessing and inspecting critical infrastructure across the county. This not only ensures that the Water Authority can stay ahead of potential emergencies but also reduce the need for replacing infrastructure.
Inspections involve crews entering the drained pipelines and evaluating around 30 miles each year. The pipelines traverse the hilly terrain of San Diego County, and some sections are so steep that they require the use of specialized rope and rigging support teams. That’s where “Scanny” comes in. Using an array of cameras to provide high-definition video surveillance of the interior of the pipeline, invented by Water Authority staff, provides the ability to inspect these pipes without requiring specialists.
The benefit of this technology goes beyond proactive maintenance. When compared to the cost of hiring specialized rope and rigging teams, “Scanny” paid for itself in just two deployments. “Scanny” can also be deployed multiple times each year during the inspection season.
Asset management at the Water Authority is more than just using new technology, it’s a strategic investment. In round numbers, the cost to replace 1 mile of large-diameter pipeline can be around $10 million. The cost to assess and maintain the same mile of pipeline may be around $100,000 every 10 years.
