Unitywater rolls out innovative technologies with reservoir robots and “Smart Balls” that can detect leaks in pipework

Thursday, September 24th, 2015

In order to save money and improve its operations, Unitywater has released CCTV-equipped mini submarines and computer-chipped balls to flow through their water mainline. This is one of the many innovative new technologies that Unitywater is rolling out and is called the Submersible Remote Operated Vehicle (ROV) Robot, or what the company staff call ‘Rove.’ From an underwater vantage point, it can perform a condition assessment of reservoir interiors to check any structural or safety problems. This saves time and actually improves safety for there is no longer any need to divert water supplies while reservoirs are taken offline for human divers to perform a confined-space entry. Recently, the company used the SmartBall device through 89 kilometres of pipeline in the Landers Shute-Woombye region and it only took 3 hours and 12 minutes. These innovations allow for the monitoring of assets from inside the pipe or reservoir, rather than just drawing conclusions from indirect external clues.

KWA may use helium gas technology to detect leaks

Thursday, September 24th, 2015

Kerala Water Authority (KWA) will be replacing the Smart Ball and Sahara technology it used previously with helium gas technology to detect leaks in its age-old drinking water distribution network. This helium gas technology involves injecting the inert, non-toxic gas into the live pipeline and the dissolved helium is expected to find its way to the ground surface if there are leaks in the pipeline. The path of the line will be traced along the ground using sensors to measure helium concentration. The Kerala Water Authority (KWA) will be replacing costly leak detection tests with this helium gas technology where the cost for testing a metre line is only around Rs.80 compared to Rs.6.5 lakh for one Smart Ball and Rs.1,000 for scanning one metre using Sahara. Some of its other advantages also include the fact that the line no longer needs to be shut down and the test can also be used in small distribution lines made of any material. A team from KWA is set to visit Mumbai to get a first-hand account of the leak detection tests that have already been conducted.
