Sewer Pipes: How Long Do They Really Last?

February 5, 2023by Alex

Sewer pipes play a crucial role in keeping our homes and communities clean and healthy. However, like any other infrastructure, sewer pipes have a limited lifespan. In this article, we’ll take a closer look at sewer pipes and answer the question: how long do they really last?

Types of Sewer Pipes

Sewer pipes can be made from a variety of materials, each with their own lifespan. Some of the most common materials used for sewer pipes include:

  • Clay: Clay pipes have been used for centuries and can last up to 50-60 years.
  • Cast iron: Cast iron pipes are durable and can last up to 100 years.
  • PVC: PVC pipes are a more modern material and can last up to 100 years.
  • Orangeburg: Orangeburg pipes are made of a tar-like material and have a lifespan of 30-50 years.

Factors Affecting Lifespan

The lifespan of sewer pipes can be affected by several factors, including:

  • Material: As mentioned above, different materials have different lifespans.
  • Age: Older pipes are more likely to break down and fail.
  • Environmental factors: Soil conditions, temperature changes, and ground movement can all impact the lifespan of sewer pipes.
  • Maintenance: Proper maintenance, such as regular cleaning and inspections, can help extend the lifespan of sewer pipes.

Signs of Sewer Pipe Failure

It’s important to be aware of the signs of sewer pipe failure, as catching the problem early can help prevent costly repairs or replacement. Some signs to watch out for include:

  • Slow draining or standing water in sinks, showers, or toilets.
  • Unpleasant odors coming from drains.
  • Gurgling sounds coming from drains.
  • Sewage backups or overflows.

Pipe Camera Inspection

If you suspect that your sewer pipes may be failing, a pipe camera inspection can help identify the issue. A pipe camera is a specialized tool that allows plumbers to see inside your pipes and identify any blockages, cracks, or other damage.

Pipe Relining

If your sewer pipes are damaged or broken, pipe relining can be a cost-effective and efficient solution. Pipe relining involves inserting an epoxy liner into the damaged pipe and curing it to create a new, seamless pipe within the existing pipe. This no-dig solution can extend the lifespan of your pipes by up to 50 years or more.

Pipe Relining Cost

The cost of pipe relining can vary depending on several factors, including the length and diameter of your pipes, the extent of the damage, and the location of your pipes. However, it is generally less expensive than traditional excavation methods because it requires less labor and materials.

Wrapping Up

Sewer pipes have a limited lifespan, but proper maintenance and repairs can help extend their lifespan and prevent costly replacements. If you suspect that your sewer pipes may be failing, consider contacting Streamline Pipes for a pipe camera inspection or pipe relining services. Our team of experienced and licensed plumbers can help ensure that your sewer pipes are functioning optimally for years to come.


Frequently Asked Questions

What Is Pipe Relining?

Pipe relining is a trenchless pipe repair method that uses a resin lining to fix pipes. The existing pipe is cleaned and inspected, then lined with a resin material that’s cured to form a new pipe within the old pipe. With Streamline Pipes, you can expect 60 years of service life out of your relined pipes!

If The Pipe Has Collapsed Can It Be Relined?

If your pipe has collapsed partially, we can reline it. If the sewer or stormwater pipe is fully collapsed then this will require, digging and a pipe replacement, to fix it correctly and costs more in labour. The pipe is impregnated with an epoxy Liner. Once cured, this creates a ‘new pipe, within the old pipe’. Very similar to a medical ‘stent’.

The benefits of using pipe relining for a cracked or partially collapsed pipe include:

  • No digging required
  • Permanent solution
  • Cost-effective
  • Less disruption – you can use your pipes within hours not days.
  • Landscaping, flooring, and driveways are not damaged.

How Long Does Pipe Relining Take?

It depends on many factors, including the size of the pipe and the access to this pipe. In most cases, your pipe can be relined in a few hours.

How Long Does Pipe Relining Last?

Pipe relining is a long-term solution. The pipe lining can last just the same if not longer than replacing in with a new PVC Pipe. Once it is in place you don’t have to worry about repairing or replacing it for years.

Relined pipes are more cost-effective than replacement of the entire pipe, which can be very expensive. Relining leaves your property intact, so there’s no need to dig up your yard or pathways or remove any landscaping features. You won’t even notice when our qualified plumbers are onsite!

StreamlinePipe relining saves money in the long run because:

  • It doesn’t require digging up yards and pathways in order to replace pipes that may be causing water damage under concrete slabs or driveways
  • We guarantee our work for 60 years – an industry first

How Does CIPP Relining Work?

Cured-In-Place-Piping (CIPP) relining is a method of repairing pipes that involves injecting a high-density polyurethane material into the pipe. The material hardens and forms a new pipe within the old pipe. This method of pipe repair was pioneered by Streamline Pipes and Drains over 31 years ago.

How Do I Know If My Pipes Are Blocked Or Broken?

If you are unsure whether your pipes need to be relined or repaired, contact us for a free, no-obligation inspection. We can help you to evaluate the condition of the pipes and advise you on all available options, contact us for help.

Does Pipe Relining Need To Be Done By A Specialist?

Absolutely.  Pipe relining requires specific equipment and training. The no-dig pipe repair solution is not taught at Tafe. Relining training is learnt ‘on the job’ and can take decades to perfect. It is worth thinking ‘will the plumbing company be around for 2o years to fix any possible problems”?

There are many companies out there claiming to be able to do this work effectively, but no one can match the quality and expertise of Streamline Pipes and Drains as they are only just beginning and Streamline has be Relining for over 31 years.

Is pipe relining approved by Australian standards?

Yes, pipe relining is approved by Australian standards. In fact, AS3600 (2016) and its subsequent revisions include requirements for the use of pipe relining as a method of remediation in both stormwater and sewer systems.

AS3600 is a set of standards for stormwater and wastewater systems that have been developed under the auspices of Standards Australia New Zealand (Standards NZ). The following standards apply:

  • AS3600 – general requirements for design, construction, operation, maintenance and decommissioning of water supply schemes including wastewater treatment works
  • AS3600.1 -2018 – quality management system standard for health sector facilities; quality management system standard for medical devices; other technical regulations made under Food Act 2014; classifications under Industrial Chemicals (Notification & Assessment) Act 1989; classification under Ozone Protection & Synthetic Greenhouse Gas Management Act 1989; environmental performance standards under several statutes including Hazardous Substances (Emergency Response Management) Regulations 2007; risk assessment framework under Hazardous Substances (Emergency Response Management) Regulations 2007

Can Root Intrusion Be Fixed With Pipe Relining?

Root intrusion is the result of tree roots growing into the pipes. Pipe relining is a perfect preventative solution when roots have invaded your sewer pipes, as the use of a High-Pressure Water Jet and inspection camera, is the precursor work required in order to clean and clear the blockage. Once this is done, then the StreamlinePipes relining system is able to install the pipe liner and get your pipes working again, with tree roots permanently removed from that part of the drain system.
