Who Owns the Sewer Lateral in Indianapolis?
The short answer for most of Marion County: you own the pipe from your house all the way to the main, often including the part under the sidewalk and the street. Citizens Energy Group owns the main. The connection between them — the tap — is generally yours to maintain and theirs to inspect. Confirm for your address with Citizens Energy Group (or your city utility in Carmel, Greenwood and other suburbs).
That surprises people, mostly because the expensive part of the lateral is the part under public ground.
Who owns what
| Section | Owner | Who fixes it |
|---|---|---|
| Drains and stack inside the house | Homeowner | A plumber |
| Lateral from the foundation wall to the property line | Homeowner | A sewer contractor, under a permit — check Citizens' contractor requirements |
| Lateral under the sidewalk, tree lawn and street to the main | Homeowner | A sewer contractor, under a permit, plus a city right-of-way permit for any street cut |
| The tap into the main | Homeowner maintains; Citizens inspects | A sewer contractor who meets Citizens' requirements |
| The sewer main | Citizens Energy Group | Citizens |
Citizens took over the Indianapolis sanitary and storm sewer system from the city in 2011, and the sewer bill you pay is a Citizens bill. Carmel, Greenwood and most suburbs run their own sewer utilities; ask the utility that bills you where your responsibility ends and which permit the job needs.
The permit rule
In the Citizens Energy Group service area, sewer lateral work needs a permit and an inspection of the connection, and Citizens sets requirements for the contractors who do it — check the current rules with Citizens (citizensenergygroup.com) before work starts. The contractor who does the work pulls the permit; ask for the permit number. Ask Citizens which jobs it applies to — spot repairs, replacements, lining and bursting all touch the lateral.
What it means for you:
- Ask Citizens Energy Group what it requires for work on your lateral, and ask every contractor whether they meet it.
- Get a written quote before you sign, and ask for the permit number once it is pulled.
- The permit fee should be a line on the estimate.
- The inspection is scheduled by the contractor and is part of the job timeline, which is one reason a replacement to the main usually takes two days rather than one.
- Unpermitted lateral work has no inspection record. When you sell, a buyer's camera run finds a repair with no paperwork, and the negotiation starts from there.
The point of the citizens energy sewer lateral permit and its inspection is the tap: a bad one lets groundwater into the main and sewage into a neighbor's basement. Citizens Energy Group publishes the current contractor and permit requirements.
Why the street section is the expensive part
The lateral is four or five feet deep at the house and eight to twelve at the main, because the main has to be below every basement it serves. If the main runs down the far side of the street — common on the older north-south streets — your lateral crosses under a lane of pavement at ten feet. Work in the street or public sidewalk also needs a City of Indianapolis right-of-way permit — confirm with the Department of Public Works, including any limits on cutting a recently resurfaced street. With traffic control, shoring and full-depth pavement restoration, that is $3,000–$6,000 before the pipe is touched.
That is the single best argument for trenchless lining on a street-side failure: the liner runs from the house to the main and never opens the pavement.
What Citizens will and won't do
Citizens will send a crew if the main is blocked or surcharging. If a Citizens crew comes out for a backup and finds the main is flowing, they will tell you the problem is on your side and leave. That is usually right, and it is worth a call before you pay anyone, especially if the whole block is backing up in a storm.
Citizens will not repair, clean or scope your lateral, and it will not pay for a lateral failure. The combined-sewer surcharge that comes up an old-side-of-town floor drain in a July storm is a system condition, not damage Citizens covers; the fix on your side is a backwater valve. Policies change, so check with Citizens Energy Group before you rely on any of this.
Insurance and protection plans
Because the lateral is yours, a failure is your bill. Standard homeowners policies exclude it when the cause is age, roots or wear. A service line endorsement is usually a modest add-on — ask your agent for the price, the limit and the deductible. Third-party utility line protection plans charge a monthly fee with a per-claim cap — read the cap and the exclusions. Read either one for Orangeburg and for "pre-existing conditions" before you rely on it.
The neighbor's tree, the neighbor's lateral
Roots from a tree on the tree lawn or next door in your pipe are usually still treated as your problem; whether anyone else shares the cost is a question for a lawyer, not a plumber. Shared laterals — two houses on one pipe, which turns up in some pre-1930 double lots near Fountain Square and the Old Northside — are a legal question before they are a plumbing one. The camera will show the wye; a lawyer sorts out who pays.
Questions to ask your utility before work starts
A short call or email to Citizens Energy Group (or the utility that bills you in the suburbs) saves trouble later. Ask:
- Where does my responsibility end at this address?
- What permit does this job need, and does a lining job need the same one?
- What inspection happens at the connection, and who schedules it?
- What do you require of the contractor who does the work?
- Is there anything on record for my lateral, such as a past permit?
Write down the date, who you spoke to and what they said. If a contractor tells you something different, you have a note to point to.
If you are buying or selling
For a buyer, the ownership rule is the reason to scope the lateral before closing. Once you own the house, you own the pipe to the main, including any defect the seller didn't know about. For a seller, a permit record and an after video for past work are the simplest answers to a buyer's camera run. If the line has never been scoped and the house is older, scoping it before listing means no surprises in the middle of the deal.
What to do with this
Know your pipe's material and age (the signs post has the eras). Get it scoped before you buy, and after the second clog. When work is needed, get the permit on the estimate. The about page lists what to ask any sewer contractor in Indianapolis, and the cost page has the ranges for the work itself.
Common questions
Does the city fix sewer lines on my property?
Generally no. In most of Indianapolis the homeowner is responsible for the lateral from the house to the Citizens main, often including the part under the street, and Citizens maintains the main itself. Confirm for your address with Citizens Energy Group, or with your city utility if you are in Carmel, Greenwood or another suburb.
When is the city responsible for sewer lines?
When the problem is in the main — a blockage, a collapse or a surcharge in the public sewer. If a Citizens crew finds the main flowing, the problem is on your side. If the whole block backs up at once, call Citizens before you pay anyone.
Who pays if the lateral breaks under the sidewalk?
In most of Indianapolis the lateral is the homeowner's all the way to the main, so a break under the sidewalk or the tree lawn is usually the owner's bill. The street-side part costs more because it is deeper and may need a right-of-way permit. Confirm the rule for your address with Citizens Energy Group before work starts.
