Today We remember our remarkable 104-year-old sewer rehabilitation project in Victoria! Executed during Covid critical times with extreme care and professionalism.
The large ovoid, or egg-shaped, considered by the utility to be one of its most critical assets, ranged from1,000 mm tall by 650 mm wide to 1,075 mm tall by 740 mm wide. In addition to being an area known for its shops and old architecture, the sewer runs under a part of the city that is also considered a cultural area precinct.
Barwon Water opted for cured-in-place pipe (CIPP) for the rehabilitation, as the liner could be installed quickly – within a matter of days – and with almost zero impact on it’s surroundings. The method has more than 45 years of proven success rehabilitating egg-shaped sewers.
In fact, the first project ever to use lnsituform CIPP was an egg-shaped sewer in the London borough of Hackney in 1971. That pipeline is still in service today!
