Replacing the main water line from the meter to the house commonly costs about $2,000 to $5,800 nationally, or roughly $50 to $290 per foot, depending on length, depth, pipe material and what's above the line. Trenchless replacement often runs $3,200 to $8,000. A single leak in an otherwise sound line can usually be spot-repaired for much less once it has been pinpointed.
When the buried line between your water meter and your house starts leaking, the first question is almost always how much? The honest answer is that the price swings a lot, and the biggest factor is whether you need a repair or a full replacement. Here’s what drives the cost in central Indiana, typical ranges, and how to avoid paying to replace a line that only needed one fix.
Typical costs
National cost guides give these ballpark ranges for a residential main water line (the “service line”):
| Job | Typical range |
|---|---|
| Full replacement, trenched | about $2,000–$5,800 total, or roughly $50–$290 per foot |
| Full replacement, trenchless | about $3,200–$8,000 total, or roughly $70–$250 per foot |
| Spot repair of one leak | usually a fraction of replacement, depending on depth and access |
Ranges are from national cost guides such as Angi and HomeGuide. Local prices in Johnson County vary; get written quotes.
What drives the price
- Length of the line. A house set far back from the street, common on larger lots around Trafalgar and rural Johnson County, simply has more pipe.
- Depth. Lines in central Indiana are buried below the frost line, usually 36 inches or deeper, so digging is real work.
- What’s on top. Lawn is cheap to restore. Driveways, sidewalks, patios, mature trees and irrigation lines are not.
- Pipe material. Copper, PEX and HDPE each cost differently. Old galvanized or lead lines usually mean replacement, not repair.
- Access at the house. Where the line comes through the foundation or into a basement or crawl space affects labor.
- Permits and utility coordination. Towns and utilities may require a permit, an inspection, or a utility visit at the meter.
- Utility locates. Before anyone digs, Indiana 811 must be called to mark buried utilities. It’s free, and it’s the law.
Repair or replace?
| Situation | Usually |
|---|---|
| One leak, line otherwise sound, reasonable age | Spot repair |
| Galvanized steel or lead line | Replace |
| Repeated leaks in the last few years | Replace |
| Line crushed by roots or settlement in several places | Replace |
| Low pressure because the old line has narrowed inside | Replace |
| Leak under a driveway, line otherwise good | Repair, or a short reroute around the driveway |
The expensive mistake is replacing a whole line because nobody knew where the single leak was, or digging three holes to find it. That’s what underground water leak detection prevents: the leak is located and marked first, so the plumber can quote an accurate repair.
Who pays: you or the utility?
In most Indiana communities, the utility owns the meter and the pipe up to it, and the homeowner owns the service line from the meter to the house. If the leak is right at the meter or on the street side, call your utility first. Johnson County homes are served by several providers, including Indiana American Water, the Town of Bargersville water utility and town utilities such as Whiteland and Trafalgar. See our town pages for who serves your area.
Lead service lines are a special case. Indiana American Water has state approval to replace customer-owned lead service lines at no direct charge when it finds them during its own lead line replacement work (Indiana American Water lead service FAQs). If you think your line is lead, ask your utility before paying for a replacement.
How to keep the cost down
- Confirm it’s the service line. Turn off all water, then close the main shutoff in the house. If the meter still moves, the leak is outside. See how to find an underground water leak.
- Pinpoint the leak before anyone digs. Line location, acoustic listening and tracer gas find the spot so only one small hole is dug.
- Ask about a spot repair when the line is in otherwise good condition.
- Get two or three written quotes that state the pipe material, depth, restoration of lawn or concrete, and permit costs.
- Ask your utility about a leak adjustment on the high bill once the repair is done. See water bill leak adjustments.
Signs your service line is leaking
- A soggy, sunken or greener strip between the meter and the house
- Water pooling near the meter or at the foundation
- Low water pressure throughout the house
- A meter that moves with everything off, and a higher bill

Frequently asked questions
How much does it cost to replace a water line from the meter to the house?
National cost guides put a typical main water line replacement at about $2,000 to $5,800, or roughly $50 to $290 per linear foot. Long runs, deep lines, driveways and landscaping push it higher. Get written quotes from local plumbers for your property.
Who pays for water line repair in Indiana?
In most Indiana communities the utility owns the meter and the line up to it, and the homeowner owns the line from the meter to the house. Rules vary by utility, so check with yours, such as Indiana American Water, the Bargersville water utility or your town utility.
Should I repair or replace my water service line?
One leak in a line that's otherwise in good shape is usually a spot repair. Replacement makes sense for old galvanized or lead lines, lines with repeated leaks, or when the line is too small or badly damaged.
Is trenchless water line replacement cheaper?
Per foot it often costs more, but it can save money when the line runs under a driveway, mature trees or landscaping that would otherwise be torn up and restored.
Does homeowners insurance pay for a water line replacement?
Standard policies usually don't pay to replace a worn-out service line. Some insurers and utilities offer optional service line coverage. Check your policy and any utility protection plan you may have.
