Due to its age and the natural demand that high-density living places on a building’s infrastructure, the plumbing system – which was original to the building and dated back to the 1960’s – had begun to fail.
Like many post WW2 high-rise developments in Sydney, the plumbing system was made primarily from cast iron pipework, which naturally deteriorates over time and has a life expectancy of around 50-years. Leaving this, and many other similar buildings in Sydney, in some serious strife.
The building’s wastewater system consists of a number of vertical stacks, which run from the roof to the ground level, servicing kitchens, bathrooms and laundries.
Upon conducting a thorough inspection of each vertical stack, the team found that the original cast iron pipework had rusted, cracking and breaking in multiple sections, which was causing wastewater to escape and flood both common and private areas.
Due to both the condition and position of the vertical stacks, patching or replacing the damaged sections would have been difficult and extremely expensive. Pipe relining (as always) provided a much cheaper and considerably less disruptive option for the owners.
