Trenchless Sewer Repair in St. Louis, MO

Trenchless sewer repair is a family of no-dig methods — primarily CIPP (cured-in-place pipe) lining, pipe bursting, and slip lining — that rehabilitate or replace failing sewer lines through small access pits or existing manholes instead of excavating the full length of the pipe. It's faster, cheaper to restore, and less disruptive than traditional dig-and-replace.

Most residential trenchless sewer repairs in the St. Louis metro fall between $4,500 and $15,000 depending on length, depth, pipe diameter, and method. Municipal mainline projects are bid per linear foot. Every job starts with a free camera inspection and written estimate.

A typical residential lateral CIPP lining or pipe burst is completed in 1–2 days, including the camera inspection, cleaning, installation, and post-job CCTV. Traditional dig-and-replace usually takes 1–2 weeks plus restoration. Municipal mainline work is scheduled per the bid documents.

CIPP liners and HDPE pipe installed via pipe bursting both carry a 50-year design life. They're resistant to corrosion, root intrusion, ground movement, and the common failure modes that destroyed the original clay, Orangeburg, or cast-iron pipe.

Yes. GreenFlow Solutions works directly with the Metropolitan St. Louis Sewer District (MSD), Missouri American Water, and municipalities including the City of St. Peters and the City of O'Fallon. We're prevailing-wage capable, bonded, insured, and experienced with public-bid specifications, traffic control plans, and the reporting MSD and municipal engineers require.

We rehabilitate or replace clay, Orangeburg, cast iron, Transite, concrete, PVC, and HDPE sewer lines. CIPP lining works inside most existing pipe materials; pipe bursting fully replaces them with new fused HDPE.

CIPP lining installs a resin-saturated liner inside the existing pipe and cures it into a new structural pipe-within-a-pipe — best for cracked, leaking, or root-intruded lines that still have shape. Pipe bursting fractures the old pipe outward and pulls a new HDPE pipe through in its place — best for collapsed lines or when you need to upsize capacity.

Yes — we run 24/7 emergency response for collapsed mains, sewer backups, and active sinkholes across the St. Louis metro. Call our office to dispatch a crew.
