Inspection camera assesses water main for blockages 

Problem: When unusually low flow ratings were observed in a 12-inch HDP water main in Jupiter, Florida, the city’s utility department sought out technology that could identify the cause of the unusually low flow.

Solution: Technicians from National Water Main, a subsidiary company of Carylon Corp., used Aquam Pipe Diagnostic’s LDS1000 condition assessment technology to identify the cause of the low-flow rates under live pressure. The inspection camera was inserted into the 12-inch main through a 3-inch valve. The system uses a tri-sensor head with a high-resolution camera, and internal hydrophone and sonde. The camera uses the pipe flow and a drogue (parachute) to carry the camera down the water main. 

Result: Technicians were able to survey 2,000 feet of pipe and determine the cause of the problem. With this data, the city will be able to properly execute a plan to reduce the sediment buildup that was causing the low-flow rate. 858/242-1640; www.aquamcorp.com.
