Back to NewsThe recent water crises in the Western and Eastern Cape has highlighted the need to save water and prepare for more possible droughts in the future. Despite maximum effort in saving water by residents, damaged pipes still result in the loss of millions of litres every month.Averda Sight Lines is a pipe inspection and maintenance service that can be used to check the internal structure of pipelines. “We cannot increase the amount of rainfall we get, but what we can control is how much water is lost due to leaks or breakages,” says general manager of Averda Sight Lines Claude Marais.“Obviously the full extent of the problem is difficult to quantify, but recent reports have estimated that we’re losing an average of 25% of water nationally, with the worst affected municipalities losing as much as 65% of their water,” he adds.“While it would be naïve to believe we can reduce this to zero, our experience shows that we can significantly cut water leaks through a programme of planned assessment and maintenance,” says Marais.
Technology has made pipe inspection more accurate
Averda Sight Lines has been inspecting pipes for over 20 years, working alongside municipalities and key players in agriculture and other industries. The latest imaging technology is used that allows the team to inspect a wide range of pipes, from as narrow as six millimetres up to wide mine shafts and sinkholes.Services include laser pipe profiling, sonar pipe profiling (for pipes full of liquid), multisensor pipe inspection, CCTV pipe inspection and pipe cleaning. These different applications are available for a range of pipe diameters and purposes.Some of these imaging devices are remotely operated vehicles that are equipped with CCTV cameras and laser pipe profiling systems. Other equipment is fitted with sonar and an array of sensors. They allow Sight Lines to map accurate pipe profiles and trajectories, as well as inspect the detailed internal structure of various pipelines.These remotely operated camera systems are able to travel several kilometres inside pipelines while transmitting high-definition video footage. They are equipped with zoom, pan and tilt capabilities and the video is lit by powerful LEDs, giving a detailed image of the inside of pipes.On-board inclinometers measure slopes, elevations and depressions that can help identify problem areas within pipelines. Accurate location tracking software can pinpoint exact positions of cracks, leaks and defects.This technology builds a bank of data that is relayed in real-time and can be used to create three-dimensional models of pipelines. This data is stored and used to compile diagnostic reports of the precise condition of pipes.
Diagnostic reports simplify findings
Reports include information such as classification, analysis of the condition of the structures, global positioning system (GPS) maps, geographical information system (GIS) data and more. “Presenting this type of information to customers simplifies their maintenance programmes because they’re able to understand the nature of defects, prioritise problem areas and carry out targeted repairs,” says Marais.Water utility services, municipalities and private clients, such as farmers, can benefit from these pipeline inspection and maintenance services. Not only will these offerings reduce water loss through damaged pipes, they will also reduce the overall maintenance expenditure by finding and dealing with potential problems early.___Averda is a leading waste management provider with over 50 years of experience across three continents.
