Sewer Replacement

We are experts in excavating and replacing sections of pipelines and sewers that have collapsed or cracked. As collapsed and cracked drainage systems are far more costly to ignore than to remove we will help you to make sure the job is done right the first time.

One reason why sewer main repairs costs more than an otherwise simple plumbing job is that the sewer main line is entirely under the ground, often below gardens, lawns, driveways, or patios. Your yard may need to be excavated or your driveway jackhammered to even access the sewer main.

Traditional dig-and-replace sewer work can require a lot of invasive excavation and result in a patched-up yard, but can be a relatively simple project; an excavator digs up the old pipes, new ones are installed and the trench is refilled.

Even though we have the latest electric eel drain cleaners, hydrojet high pressure water jet blasters and CCTV drain cameras, some drains just cannot be unblocked. This is because the drain has collapsed or something solid like a fragrance holder, garden sprinkler or a child’s toy has lodged down the drain. UPVC (plastic) drains can also become blocked because of tears in the fittings and squashing.

We Repair and Replace and Upgrade:

  • Sewer Pipes
  • Vent Pipes
  • Inspection Points
  • Storm Water Pipes and Down Pipes

There are only a few situations where the section of the sewer that needs repair or replacement is actually on the water utilities property rather than your own, like in the street.

The Australian Standards for Sanitary Plumbing & Drainage (AS/NZS 3500) requires all sewer drains to be fully functioning and sealed to prevent sewerage getting into the surrounding soil and ground water and to prevent ground water entering the sewer system. Therefore, every drain that is broken, torn, collapsed, has tree roots in it or is overflowing does not comply to these standards.
