On Jan. 25th, 2017, Project Engineers and Technicians from National Water Main in New Jersey, and specialist pipeline diagnostics professionals from APD San Diego and the United Kingdom, mobilized to the Town of Jupiter, FL to meet with the utility department. The purpose of the initial project meeting was to explain the inspection strategy, and to introduce the equipment that would be deployed to diagnose the source of the flow restriction.
APD’s LDS1000™ system was launched into the Town of Jupiter’s 12” HDPE water main through an existing 3” valve without the need for any pipe reconfigurations or disruptions to service.
“The LDS1000™ offered the Town a real time view of the system while it was still pressurized,” said Lisa Douglas, Division Manager, Carylon Water Group.
The Town of Jupiter Water Utilities Department is capable of producing 30 million gallons of drinking water daily, serving more than 86,000 people living in the Town of Jupiter, Juno Beach, and unincorporated areas of Palm Beach and Martin Counties.
When unusually low flow ratings were observed in a 12” high-density polyethylene (HDPE) potable water pipe, Jupiter Water Utilities researched specialist technology that could identify the cause of these unusually low flow rates. Aquam Pipe Diagnostics (APD) in conjunction with National Water Main Cleaning Co, a subsidiary company of Carylon Corporation and a trusted client of APD, were called upon to investigate the situation using their innovative LDS1000™ platform. The LDS1000™ is a long distance pipeline inspection platform, featuring a tri-sensor head with a HD CCTV camera for visual condition assessment, a hydrophone and a sonde for pipeline locating and accurate leak pinpointing. The system has the ability to inspect up to 3280ft in one single insertion and can be launched through existing pressurized fittings on live potable water or raw water pipes.
The Results and Benefits
During the 2,500 feet real time inspection, the expert team were able to diagnose that sediment buildup throughout the pipeline caused a cumulative restriction and limited the conveyance capacity of the pipe. Flow restrictions such as this prompt significant operational inefficiencies and financial implications for a utility because the water system has to compensate for a decrease in performance. Such situations are extremely detrimental if they remain undetected.
The Town of Jupiter Utilities department is better informed regarding the internal condition of the 12” pipe and can develop a data-driven remediation plan for the future.
This survey has also created awareness within the utility regarding the importance of pipeline diagnostics as a preventative measure and a proven methodology for optimizing system conditions.
