Cities throughout Brazil are experiencing unprecedented growth. Campinas is no exception and the metropolitan area is now home to over one million people. And in just a few years, the city has earned the reputation of being the technology capital of the fifth largest country in the world. Hence its nickname, the “Brazilian Silicon Valley.”
In keeping with its technologically progressive reputation and according to Trenchless International online, Campinas city officials have purchased “trenchless machinery to replace and enlarge existing drinking water pipelines.” They made this investment not only because the technology is economical and earth-friendly but also because it worked brilliantly on a water project the city began in 2011.
SANSA, the Campinas water authority, was facing ongoing leakage problems in Sousas, a district close to the city center. But all of that stopped last June when SANSA began replacing the old asbestos cement pipes using a pipe-bursting machine.
Workers burst the first 400 meters (out of a total of 2.4 kilimeters) “in sections of 50 to 100 meters due to [the presence of] several sewer, gas and telecommunication lines along the bursting path.” Project technicians also exercised caution because the pipeline they were working on ran parallel to a large drain pipe that needed to remain intact.
The “exact position of this existing underground service line was [unknown].” Still, technicians had no difficulty with the project because the method they used doesn’t require precise coordinates. And even though the pipe was held together by numerous repair clamps, replacement–which included “disassembly of the construction and intermediate pits and the reestablishment of the water supply”– took less than three weeks.
With stories like this one, is it any wonder that more and more towns and cities around the world are using–and actively investing in– innovative infrastructure repair technologies? When nothing less then guaranteed success will do, trenchless is the one and only way to go. Period.
