GRP relining and CIPP are two methods chosen to rehabilitate the upper part of main water pipe supplying Craiova city with drinking water. Our part of the project is located close to the capturing station in Isvarna. The diameter of the host pipe is 1200 mm. The section of 700 mm will be rehabilitated using CIPP method and 1600 m using GRP relining technology. The relining works have been already started this year, all the works are planned to be finished till the end of 2022.
