Trenchless Sewer Options
“Trenchless” describes sewer repair methods that fix or replace a damaged line without digging a continuous trench. Instead, we typically dig one or two small access pits and work the repair through the existing pipe path.
CIPP Pipe Lining
A resin-saturated liner is inserted into the damaged pipe and cured in place, forming a new pipe within the old one. Best for cracks, small holes, or root damage on an otherwise sound pipe.
Pipe Bursting
A bursting head fractures the old pipe outward while pulling a new pipe into its place. Used for severely deteriorated pipe or when a larger diameter is needed.
When a Sewer Line Qualifies for Trenchless Repair
Lines that often qualify: cracks or small holes on an otherwise sound pipe, root intrusion without widespread collapse, corroded pipe with intact alignment. Lines that often don’t qualify: a fully collapsed section, severe offset joints, significant bellies needing regrading, or insufficient diameter. We confirm eligibility with a camera inspection before recommending any trenchless method.
Trenchless Repair Versus Excavation
Trenchless limits disruption to one or two access pits and is often faster once access is prepared, best suited for cracks, corrosion, and root damage on an intact alignment. Traditional excavation is sometimes still the right call for full collapse, severe misalignment, or bellies needing regrading. The right choice depends entirely on what the camera inspection shows.
Access Pits, Inspections and Permits
Most trenchless jobs need one or two access pits, typically at existing cleanouts or connection points. Every trenchless job starts with a camera inspection to confirm the pipe’s condition and locate lateral connections. The City’s Building & Safety Division issues permits through its SimpliCITY portal — sewer repair, including trenchless methods, generally requires one.
Trenchless Sewer Cost Factors
Method selected, line length and diameter, number and access of pits, pre-cleaning needs, lateral connections, and permits/inspections all shape cost.
Limitations
Not every pipe qualifies — collapsed sections, severe misalignment, and significant bellies often require excavation instead. Liners slightly reduce interior diameter, which rarely affects flow on residential lines.
Trenchless Sewer FAQs
How is trenchless sewer repair different from digging up my yard?
Instead of a trench along the full pipe path, trenchless methods work through one or two small access pits, generally meaning less disruption to landscaping and hardscape.
How do I know if my sewer line qualifies for trenchless repair?
A camera inspection is the only reliable way to confirm eligibility. It shows the pipe’s condition, alignment, and diameter.
What’s the difference between CIPP lining and pipe bursting?
CIPP lining installs a resin liner inside the existing pipe, best for cracks or corrosion. Pipe bursting fractures the old pipe and pulls in a new one, used when damage is more severe.
Will trenchless repair reduce my pipe’s flow capacity?
CIPP lining adds a thin liner layer that slightly reduces interior diameter. For most residential lines this doesn’t meaningfully affect flow.
Do I still need a permit for trenchless sewer repair?
Generally, yes. The City’s Building & Safety Division issues permits through its SimpliCITY portal, and trenchless work is typically subject to the same permitting as excavation.
What if my line doesn’t qualify for trenchless repair?
We’ll explain why and walk you through the alternative, which is usually traditional excavation for that section of line.
