Sanivar have recently completed a 750m refurbishment of a 250mm rising main in Matlock, Derbyshire. The project was promoted by Severn Trent Water (STW) following a number of asset failures that had resulted in 10 reactive repair interventions in recent years. The project was delivered through STW’s delivery alliance CSP and lining contractor Colus Specialist Projects. The 250mm Cast Iron main was found to be badly corroded over a section that ran along the High Street and into a discharge chamber in the riverside park. Originally installed in 1970 the pipe had eroded from the inside and grit had worn a groove along the base of the pipe making it susceptible to bursts.
