The frustration with pipe replacement has been the expense and disruption of digging up streets and sidewalks. A pipe segment can't be replaced without a dig, so the solution up until today has been to replace long stretches of pipe based on statistical modeling. The modeling predicts when and where pipe integrity will be at risk, but these methods are very general and result in large replacement projects.

Now there is an option that allows pinpointing analysis onto almost each and every pipe segment, freeing up much-needed funds. Pipe replacement becomes micro-surgery instead of amputation. Another benefit is that fewer digs result in smoother vehicle traffic flow. Citizens are much happier with their local governments when they spend less money and cause less congestion.

Public Water Solutions has developed advanced robotic approaches to creating economical and sustainable methods of pipeline evaluation. Our segment to segment focused methods are moving aside traditional statistical models for evaluating sewage pipelines. Our efforts with cities around the country are also proving popular with the public and local media coverage has been positive.

Our Partnerships Make The Difference

Our capabilities came together thanks to partnerships with Carnegie Mellon engineering spinoff RedZone Robotics and the University of Texas at Arlington. RedZone provides the robots created to take on a pipeline network in almost any condition. These robots are consistently able to collect and transmit data in significantly harsh environments. The analytical methods used in evaluations are under continuing development at the University of Texas at Arlington.

RedZone originated at Carnegie Mellon University as an enterprise that would make available the latest engineering advancements in robotics. Because of the dire needs of city infrastructure, they quickly settled on developing robotic solutions for the needs of pipeline networks, something that presents persistent challenges to cities all over the world.

Robots Go Deep Inside The Pipes

The RedZone robots are capable of moving through sludge and around build-up. Crud that has made pipes inaccessible in the past can now be fully traversed by the RedZone robots in order to collect data. Because the robot can get around an entire network of pipes, each segment can be evaluated up close by the robot's sensors. By having interior access to the pipes, our team at Arlington make smarter evaluations. The result is fewer unpopular and expensive digs to replace long stretches of pipe.

Public Water Solutions will provide more data and analysis than previous methods, for less money, and that data will allow engineers to make segment by segment decisions on pipe replacement. The savings and popularity of this program are easily understood. This partnership offers a new dimension in sewage pipelines, namely making pipeline maintenance a more popular part of a city's service program.
