SaniTube on relining a 300mm Cast Iron main at Agbrigg Bridge, Calderdale, UK

26 January, 2021

Sanivar have recently completed a challenging refurbishment of a rising main feeding Calder Treatment Works in Wakefield. Working with Peter Duffy Ltd, this job involved relining a 300mm cast iron main, a section of which ran via a pipe bridge under a mainline railway. The high-pressure rising main was badly corroded and previous temporary repairs using clamps had been unsuccessful, necessitating the refurbishment of a 250 metre section. The pipe bridge crossed the River Calder and there wer [...]

The existing PVC rising main suffered a history of bursts, and a recent leak had caused effluence to leak through the bridge decking and into a neighbouri [...]

30 metre SaniTube with 45 degree bend at Colburn STW, UK

27 February, 2020

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. The pipe system was built in 1974 using 6m PVC sections which were glued together. 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 [...]
