Sydney Water supplies nearly 1.4 billion litres water to over 1.7 million homes and commercial hubs. Since the last few years, the water supply has been affected due to damages in water pipelines.
The reports state about 7.5% (129.5 megalitres per day) of Sydney’s water is lost due to leakage from 22,000 km of pipes. This led to a compulsory restriction on water usage by 50% in the last decade. Hence, many households moved to pipe relining in Sydney to prevent wastage of water.
Another primary concern of pipeline damage is the intrusion of tree roots. Also, the concrete debris in the pipelines cause blockage and affect the drainage system. If you experience cracked walkways from sinkholes, foreign objects in the toilet bowl, or awful odour, you must consider relining the pipes. Let’s study the process of pipe relining.
Check for Any Damage
Every household in Sydney has a minimum of four pipelines in their homes. Only 4.6% of the population in Sydney stay in social houses. The pipeline inspection begins with CCTV cameras being inserted in the pipeline.
A thorough examination of the pipeline helps to check for cracks, leakage, tree-root intrusions, and debris blockage at junctions. During this process, the size of the pipe is also measured to prepare the liner.
Removal of Obstructions
About 59% of Sydney homes are privately owned, and hence, the pipeline repairing has to be carried out by the owners themselves. If you find the blockages or obstructing material in the pipeline, the experienced companies for pipe relining in Sydney use a high-pressure drain cleaner or water jet to remove the debris.
Locating the Problem Areas
Jacaranda tree is found in Sydney, and it blooms in November. Many private landowners have these trees planted around their homes. Tree-root intrusions are one of the contributors to the problems in drainage pipelines.
After the removal of blockages, the CCTV camera is inserted in the pipeline to locate the damaged areas like holes and cracks.
Placing the Liner
Pipeline liner is either made of impregnable fiberglass cloth or spread-tow carbon fiber. A custom-made bladder and liner are inserted into the pipeline and placed over the damaged area. The bladder is inflated with compressed air that leads to the expansion of the liner.
The liner is filled with epoxy resin that settles on the damaged pipeline’s inner surface and bonds tightly. It is then left in the pipeline itself for the curing process to take place. The pipeline liners work on any age-old pipes made of PVC, HDPE, cast iron, cement, pressure pipes, asbestos downpipes, or earthenware.
Only Watermark certified liners are used in plumbing services in Sydney. The last examination conducted is to check whether the liner is cured or not. Once cured, the bladder is deflated and taken out, leaving the liner in the pipeline.
In reality, this is the final checking process that decides whether the newly created pipeline is ready for use. Pipe relining in Sydney is a long-term solution as the product has a life expectancy of 45 to 50 years. Some pipeline relining services offer a warranty of 25 years irrespective of the size of the job.
