Sewer line repair in Indianapolis: a homeowner's guide
A basement floor drain that backs up when it rains, a toilet that gurgles when the washer drains, a soft green stripe across the front yard. On the old side of Indianapolis that is usually a clay or Orangeburg lateral at the end of its life. This guide explains what the camera should show first, and how to get a written price for the fix that matches it; estimate requests go to an independent local sewer contractor partner who does the work.

What is under an Indianapolis yard
Most of the houses inside the old city limits — Meridian-Kessler, Broad Ripple, Irvington, Garfield Park, Fountain Square, Eagledale, the ranches out to Warren Park and Beech Grove — were connected to the sewer between the 1920s and the early 1970s. The lateral that runs from the basement wall to the main in the street is whichever pipe was cheapest that year. Before the war it was vitrified clay in short sections with mortar joints. After the war a lot of subdivisions used Orangeburg, a tar-soaked wood-fiber pipe rated for about fifty years that goes oval as it fails; much of it is failing now. Some houses have cast iron for the first ten feet and clay beyond that.
All three are past their design life. Clay joints open up as the ground moves and let roots in. Orangeburg flattens under a driveway. Cast iron rusts from the inside until the bottom is gone. None of this is a maintenance failure; the pipes are old and the silver maples on the tree lawn have had seventy years to find them.
The second thing that makes Indianapolis different is the sewer itself. Citizens Energy Group runs the system, and the older neighborhoods sit on combined sewers that carry stormwater and sewage in the same pipe. When a summer storm drops two inches in an hour, that pipe surcharges and the water looks for the lowest opening — which is often a basement floor drain on a street off College Avenue or Shelby Street. That is a different problem from a broken lateral, and the camera tells you which one you have before anyone talks about digging.
Sewer line repair in Indianapolis: the options
Sewer line repair (Indianapolis, IN or any of the suburbs around it) starts the same way: a recorded camera run, then the cheapest fix that actually ends the problem.
Sewer line repair — a camera-located spot repair of the one or two bad sections: a collapsed clay joint, a root ball at the foundation wall, a crushed Orangeburg run under the walk. Most are $1,500–$4,000 and done in a day. Details on the sewer line repair page.
Sewer line replacement — a new PVC lateral from the house to the main when the whole run is failing. Open trench where the yard allows it, $4,000–$15,000 depending on depth and what has to be restored. See sewer line replacement.
Trenchless sewer repair — cured-in-place lining or pipe bursting through the old pipe from one or two pits, which is how a lateral under a 90-year-old oak in Meridian-Kessler gets replaced without cutting the tree down. $6,000–$20,000. The trenchless page explains when each method works.
Sewer camera inspection — the recorded scope that every honest quote starts with. $250–$500; many contractors credit it against the repair — ask. See sewer camera inspection.
Hydro jetting and drain cleaning — clearing roots, grease and cast iron scale from a pipe that is still sound, and the prep step before lining. See hydro jetting.
Permits and Citizens Energy Group
In the Citizens Energy Group service area, sewer lateral work usually needs a permit and an inspection of the connection. The rules can change, so ask Citizens Energy Group what it requires for work on your lateral before work starts. The contractor who does the work pulls the permit; it should be its own line on the estimate, and you can ask for the permit number. If a contractor tells you a permit isn't needed for a lateral, ask why — unpermitted work tends to become the owner's problem at resale.
Areas this guide covers
Marion County — the old north side, Irvington, the south side, Speedway, Lawrence and Beech Grove — and the suburbs around it: Carmel, Fishers, Noblesville and Westfield to the north, Zionsville and Brownsburg to the northwest, Avon and Plainfield to the west, Greenwood to the south. Carmel and Greenwood have their own pages because their older blocks fail the same way the city does: Carmel and Greenwood.
Emergency sewer repair in Indianapolis: if it is backing up now
Stop running water and don't flush. If the backup only happens during or after heavy rain, say so in the estimate request — it changes what the contractor brings, and it may not be your lateral at all. The post on signs of a broken sewer line covers what the symptoms mean; the sewer line repair cost page has typical 2026 ranges.
Sewer services across Indianapolis
Spot repair, full replacement, trenchless lining and pipe bursting, camera inspection and jetting. Here is which one a pipe usually needs, and which ones it doesn't.
Sewer Line Repair
A camera-located spot repair of the one or two bad sections — a collapsed clay joint, a root ball, a crushed Orangeburg run — instead of replacing a pipe that is mostly fine.
Sewer Line Repair →Sewer Line Replacement
A new PVC lateral from the foundation wall to the Citizens main when the clay or Orangeburg is failing along its whole length. Open trench, permit, inspection, restoration.
Sewer Line Replacement →Trenchless Sewer Repair
Cured-in-place lining and pipe bursting through the old pipe — one or two pits instead of a trench under the oak, the driveway or the street. $6,000–$20,000.
Trenchless Sewer Repair →Sewer Camera Inspection
A recorded video scope from the cleanout to the Citizens main, with every crack, root and offset located and its depth marked on the lawn. Usually $250–$500.
Sewer Camera Inspection →Hydro Jetting & Drain Cleaning
High-pressure water that strips roots, grease and cast iron scale from the pipe wall — the right tool when the line is sound but choked, and the prep step before lining.
Hydro Jetting & Drain Cleaning →How a request works
- Tell us what happened
What you've seen, where the water shows up, whether it tracks rain, and how old the house is. Photos of the floor drain help. - A local contractor scopes the line
A recorded camera run from the cleanout to the main, with the bad spots located and their depth marked on the lawn. Ask to watch and keep the file. - You get a written price
Repair, replacement or trenchless, with the permit, restoration and any pavement cut as separate lines. Ask how long the price holds; walk away from a price that expires today. - You decide
No obligation. Spot repairs and most linings usually take a day; an open-trench replacement usually takes one to three days including the inspection at the tap. - Check the finished work
Ask for the after video and the warranty in writing: its length, what voids it and whether it transfers.

Questions plumbers get asked
How much does sewer line repair cost in Indianapolis?
A camera inspection is usually $250–$500. A spot repair of one bad section runs $1,500–$4,000. Replacing the whole lateral by open trench is $4,000–$15,000, and trenchless lining or pipe bursting is $6,000–$20,000. Depth, pavement and permits move the number. Those are typical ranges for Marion County in 2026, not a quote.
Do I need a permit for sewer lateral work in Indianapolis?
Usually, yes. In the Citizens Energy Group service area lateral work needs a permit and an inspection of the connection, and the requirements can change — ask Citizens Energy Group what it requires for work on your lateral. The contractor who does the work pulls the permit; ask for the permit number and see it as its own line on the estimate.
Why does my basement drain back up only when it rains?
In the older neighborhoods the sewer is combined — stormwater and sewage share one pipe. A heavy storm fills it faster than it can drain, and the surcharge pushes up through the lowest opening, which is your floor drain. That is a system problem, not a broken lateral. A backwater valve on the lateral is usually the fix, and a good contractor will say so rather than sell you a dig.
Can a sewer line be repaired without digging up the yard?
Often. Cured-in-place lining runs a resin-soaked liner through the existing pipe and cures it in place; pipe bursting pulls a new pipe through while breaking the old one apart. Both need one or two small pits rather than a trench. They don't work on a fully collapsed pipe or a bad sag, which the camera shows first.
What is Orangeburg pipe and do I have it?
A bituminized wood-fiber pipe used on a lot of Indianapolis homes built from roughly 1945 to 1972. It softens, goes oval and eventually collapses. If your house is from that era and the camera shows an egg-shaped pipe with blistered walls, that's it. Orangeburg is a replacement job, not a repair — it can't be lined reliably.
What should I get from an Indianapolis sewer contractor before I sign?
A written quote that names the method, length, depth and restoration, with the permit as its own line. Ask whether the contractor pulls the Citizens Energy Group sewer lateral permit, and ask for the permit number once it is pulled.
