The project involved the restoration of a 250mm section of rising main which ran under above ground infrastructure and adjacent to high voltage power cables. The ductile iron pipe had become corroded and needed to be replaced as part of a wider refurbishment on site. Without refurbishment the ductile iron pipe posed a pollution threat and MMB were seeking a ‘no dig’ solution to minimize on site disruption and avoid the prohibitive costs and danger of accessing the section of main through tr [...]

2766 meters SaniTube DN150 and DN200 for WGA Vorkenbuch

21 December, 2018

The two potable water mains which connect the water catchment plant “Vorkenbruch” with the elevated tanks in the “Steinbergstrasse” carry about 45m3/h of water in total.

During a regular pipe inspection water leakage was found in various parts of the pipe system due to abrasion and fatigue. Conventional methods for pipe rehabilitation through excavation is usually time-consuming, expensive, noise intense [...]
