To maintain its distribution network of drinking water (1), the city of Rodez has chosen a revolutionary system. No more open. Now you can inject the resin inside the pipe to seal leaks.

Demonstration was made yesterday morning on Belle Isle Boulevard, up to the college Fabre. "For a month, there was a leak in one of the main ducts of the drinking water system of the city, at the square Monteil. After a small period of reflection, we decided to call a company (ART Europe, Ed) which uses a fast and efficient. It causes no discomfort to the inhabitants, prevents the development of a project that lasts, minimizes the impact of noise and dust, "says Jean-Albert Bessieres, city councilor, delegate to the water.

The cost of the operation is €70 000

The head of water at great Rodez, Benedict Legeay, explain: "The pipe cracked cast iron, which leaves the tank is 6 meters deep. We can either dig a trench, is that of finding an alternative technique for not opening the surface. We chose the second alternative is that the injection of resin inside the pipe. This technique creates a new pipe into the existing pipeline. The resin cures in a few seconds and seals the material. On this site, nearly 50 meters have been cleared. " In the opinion of the latter is a permanent process.

"However, rather than to eliminate iron, it is left inside and we just reinforce it. Furthermore, it is useful to say that this flight is not due to lack of maintenance. The cast is asked for nearly 50 years. It has a great quality: it is very durable. But it also has a big flaw, that if the ground breaking move, "said Jean-Mathieu decumbent, the sales manager of the company ART Europe.

The cost of the operation is estimated at € 70,000 for a week of work. Four injections of resin, which lasted an hour and a half each, will be made in the coming days. Everything should return to normal next Monday. The operation went virtually unnoticed by the residents because it did not lead to water shortages or low, it had no consequences for motorists or pedestrians. Nevertheless, it remains just to fill the gap created below the square.

(1) The network is a length of 186 km. "It is in pretty good shape," according to its leaders.
