About Sewer Line Repair & Replacement in Cape Town CBD

When a sewer line cracks, collapses, or becomes so damaged that clearing blockages no longer works, repair or replacement is the only permanent solution. Sewer line problems are serious - a failing sewer pipe can cause raw sewage to back up into your home, contaminate groundwater, undermine foundations, and create significant health hazards.

Abacas Solution handles all types of sewer pipe repair and replacement in the Western Cape. We work with every pipe material found in South African homes: clay pipes common in pre-1970s properties, asbestos-cement pipes used through the 1980s, PVC pipes from the 1990s onwards, and concrete sewer mains. Our approach starts with a CCTV inspection to assess the damage accurately, then we recommend the most appropriate repair method.

For localised damage such as a single cracked section or displaced joint, we can often perform a spot repair by excavating only the affected area. For extensively damaged or deteriorated pipes, full replacement with modern PVC is the best long-term investment. Where property conditions allow, we offer trenchless pipe relining as a less disruptive alternative - a resin-coated liner is inserted into the existing pipe and cured in place, creating a new pipe within the old one without excavating your garden or driveway.

This is one of several specialist services we offer under drains & sewage in Cape Town CBD. As part of our Cape Town CBD plumbing team, we bring over 25 years of hands-on experience to every job.

When to Call for Sewer Line Repair & Replacement

Call when drain clearing no longer fixes recurring blockages, when sewage smells persist around your property, when you see ground subsidence over the sewer line, when a CCTV survey has revealed pipe damage, or when purchasing a property where the drain survey has identified sewer line problems.

Our Sewer Line Repair & Replacement Process

1

CCTV Diagnosis

We run a CCTV camera through the sewer line to identify the exact location, type, and extent of the damage. This determines whether spot repair, section replacement, full replacement, or trenchless relining is the best approach.

2

Repair Plan & Quote

Based on the CCTV findings, we present you with repair options, explain the pros and cons of each, and provide a detailed quote. We always recommend the most cost-effective permanent solution for your specific situation.

3

Excavation & Repair

For traditional repairs, we carefully excavate to expose the damaged section, remove the failed pipe, and install new PVC pipe with proper fall and bedding. For trenchless relining, we insert the liner through existing access points with minimal digging.

4

Testing & Backfill

We run water through the repaired section and perform a post-repair CCTV check to confirm the fix is watertight and flowing correctly. The trench is backfilled and compacted in layers, and the surface is restored.

Many homeowners in Cape Town CBD who need sewer line repair & replacement also require blocked drains in Cape Town CBD and drain cleaning & jetting. We handle everything, so you only need one call.

Safety & Compliance

Sewer line work involves potential exposure to raw sewage, which carries bacteria, viruses, and parasites. Our team uses appropriate personal protective equipment and follows safe work practices. If asbestos-cement pipes are encountered, they must be handled according to the Occupational Health and Safety Act and Asbestos Abatement Regulations by registered contractors. We ensure all excavations are properly shored and barricaded for safety.

Sewer Line Repair & Replacement Cost in Cape Town CBD

Sewer line repair costs vary significantly based on the extent of damage, pipe depth, and access difficulty. A spot repair of a single damaged section typically costs R2,500-R5,000. Section replacement of 3-10 metres ranges from R5,000-R15,000. Full sewer line replacement for an average residential property costs R15,000-R35,000. Trenchless relining, where applicable, typically costs 20-30% more than traditional replacement but avoids garden and hardscape damage.

Frequently Asked Questions

How do I know if my sewer line needs repair?

Warning signs include recurring drain blockages despite professional clearing, sewage smells in your yard or near manholes, patches of unusually green or lush grass over the sewer line (indicating a leak feeding the soil), sinkholes or depressions in the ground above the pipe route, and visible sewage or damp patches near manholes. A CCTV inspection is the definitive way to confirm the pipe's condition.

How much does sewer line replacement cost in Cape Town CBD?

Sewer line replacement costs in Cape Town CBD depend on the total length, pipe depth, and surface material above (lawn vs. paving vs. driveway). A typical residential sewer line replacement of 10-20 metres costs R10,000-R25,000 including excavation, new PVC pipe, backfill, and basic surface restoration. We provide detailed quotes after CCTV inspection so you know exactly what to expect.

What is trenchless sewer repair?

Trenchless repair involves inserting a resin-coated flexible liner into the existing damaged pipe through a small access point. The liner is inflated against the pipe walls and cured with UV light or hot water, creating a smooth new pipe inside the old one. This avoids digging up your garden, driveway, or paving. It is ideal for pipes with cracks, joint displacement, or moderate root damage, but not suitable for completely collapsed pipes.

How long does a sewer line replacement take?

A typical residential sewer line replacement takes 2-4 days depending on length, depth, and ground conditions. Spot repairs can often be completed in a single day. Trenchless relining is usually completed in 1-2 days. We plan the work to minimise disruption and always provide a temporary waste arrangement if your toilets will be out of service during the repair.
