You step outside on a Saturday morning and find a soaked patch of grass that wasn’t there yesterday. Maybe water is pooling beside the meter box, the lawn looks greener along one narrow strip, or a small stream is moving toward the street. The immediate question is simple: water leak in yard, who to call?

The answer isn’t automatically “a plumber.” The leak’s position in relation to the water meter decides whether you should call a municipal water utility, a licensed plumber, 811, or an irrigation technician. Make that distinction first, and you can avoid paying for a visit that was never your responsibility.

Stay Calm and Stabilize the Situation First

Don’t walk straight into the wet area with children, pets, or bare feet. Soggy ground can hide unstable soil, and water that smells foul may indicate a sewer problem rather than a clean-water leak. Keep everyone away while you determine whether the water is moving, spreading, or carrying an odor.

Four actions before making a call

Stop obvious outdoor sources. Turn off irrigation zones, outdoor faucets, and hose bibbs that could be feeding the wet area. If the patch dries or the flow stops after irrigation is isolated, the problem may belong to the sprinkler system rather than the home’s main water line.
Find both shutoffs. Locate the home’s main shutoff valve and the curbside meter box. Don’t force a buried or corroded valve, but clear leaves and soil so a plumber or utility crew can reach the equipment quickly.
Watch the meter. Turn off fixtures inside the house and avoid using water while you observe the meter. The U.S. Environmental Protection Agency recommends checking the bill and meter when chasing down leaks, and it says movement during a no-use period indicates that water is escaping somewhere in the system. The EPA leak detection checklist also identifies a winter household use level above 12,000 gallons per month for a family of four as a serious leak signal.
Record what you see. Take phone photos of the wet patch, standing water, erosion, the meter reading, and any damage near the foundation. Add the time to your notes. This gives the utility, plumber, and insurer a clear starting point instead of a vague report that “the yard is wet.”

Practical rule: Stabilize the area, check the meter, then decide who owns the pipe. Calling first and investigating later often creates a billable detour.

Undetected household leaks matter even when the yard looks normal. The EPA says the average home leaks nearly 10,000 gallons of water per year, enough to wash about 300 loads of laundry, and those leaks can add about 10% to water bills. The source is worth reviewing if you also notice a rising bill, damp soil, or unexplained water use.

What a Yard Leak Really Is and Where It Lives

A yard leak usually involves water escaping from buried plumbing between the municipal supply and the house. That buried route is commonly called the water service line. It runs from the meter area toward the home’s main shutoff and foundation, although the exact ownership boundary depends on the local utility’s rules and the location of its equipment.

The meter is the key reference point. The pipe from the street to the meter may belong to the utility, while the line from the meter to the house generally falls on the property owner. Don’t assume the property line alone decides responsibility. In many neighborhoods, the meter is the practical dividing point.

Match the symptom to the likely system

A narrow strip of greener grass can follow a buried water service line or irrigation lateral.
A persistent soggy patch suggests water is escaping continuously, not only during a scheduled sprinkler cycle.
A sunken area or muddy depression can mean soil is washing into a void around damaged underground plumbing.
Clean water inside a meter box points toward the meter or street side, but the utility should confirm the boundary.
Foul-smelling pooling raises a sewer concern, especially if toilets or drains are also behaving badly.
Low pressure at several fixtures can accompany a significant service-line problem, although a fixture-specific issue may have a different cause.

Irrigation leaks follow a different pattern. A broken sprinkler lateral, valve, or zone line may release water only while the timer runs, so note whether the wet area appears after irrigation cycles. For lawn symptoms such as persistent saturation, uneven watering, or overwatering, this Southeast Texas lawn watering guide offers useful background on distinguishing lawn conditions from plumbing problems.

A sewer line issue belongs to a separate decision path. Sewage odors, backups, and a clogged toilet that won’t flush can involve tree roots, grease, wipes, broken lines, defective joints, or stormwater entering the sanitary system. The EPA lists those contributors in its frequent questions about sanitary sewer overflows. Don’t treat foul water in the yard as a routine freshwater leak.

The Four Professionals Who Handle Yard Leaks

Four parties may be involved, but they don’t do the same job. The fastest route is to give each one the problem it owns.

Professional	Scope of Work	When to Call
Licensed plumber	Diagnoses and repairs private-side service lines, underground plumbing, leaks near the house, and water entering the structure	Call when the leak is on the homeowner’s side of the meter or the source remains uncertain after the utility checks
Municipal water utility	Inspects utility-side piping, the meter, curb stop, and public water infrastructure	Call when water appears in the street, near public property, inside or around the meter box, or before hiring a plumber for a boundary question
Utility locator through 811	Marks buried gas, electric, telecommunications, and water lines before excavation	Call before any digging, trenching, or service-line replacement
Landscaper or irrigation technician	Repairs sprinkler laterals, irrigation valves, timers, and zone piping	Call when the leak occurs during irrigation or clearly belongs to the sprinkler system

A plumber shouldn’t excavate blindly. Buried gas, electrical, communications, and water lines can cross the proposed repair path. Dial 811 before digging so the underground utilities can be marked. The locator doesn’t repair the leak and usually won’t decide who owns the service line, but skipping that step creates a dangerous excavation.

Local utility rules can vary, so start with the provider when the leak is near the meter or public right of way. Columbus guidance explains that many yard leaks sit on a property’s plumbing line, while the utility may inspect and arrange service when the issue falls within its system. Its water leak guidance for streets, yards, hydrants, and meters shows why the ownership question comes before excavation.

For commercial sites, the same logic applies, but a large irrigation network can make diagnosis harder. A resource on commercial property leak detection can help property managers separate irrigation failures from domestic or service-line leaks.

Finding the Leak Before You Make the Call

Before calling anyone, confirm whether water is leaving the house-side system. Shut off faucets, washing machines, toilets, ice makers, and irrigation. Keep the property quiet while you watch the meter’s small flow indicator or dial.

A moving indicator means water is still flowing somewhere. The EPA recommends checking the meter during a no-use window, and its checklist explains that movement during a two-hour period without water use makes a leak likely. Use the EPA’s meter-check procedure if the reading is difficult to interpret. This simple check can prevent a billable visit for a fixture problem or a leak the utility controls.

Read the ground like a plumber

Walk from the meter toward the house and inspect the likely pipe route. Look for:

A wet patch between the meter and foundation, which points toward the private service line.
Water collecting in the meter box, where the utility should inspect before private excavation.
New mud or erosion near the street, which may indicate the public side or a failed connection.
Grass greener than the surrounding lawn, showing where buried water may be reaching the surface.
A hissing sound on a quiet morning, especially near exposed valves or pavement.
Water appearing only after the sprinkler timer runs, which favors an irrigation fault.

Do not remove the meter or operate utility equipment. Photograph the indicator, record whether it keeps moving, and give the caller those observations. If the source is beneath a slab, crawlspace, wall, or finished yard, leak detection can locate moisture before anyone excavates. Homeowners searching for IICRC-certified leak detection near me may find that service useful when water has reached the structure.

Property Side Versus Utility Side and Why It Matters

The meter boundary controls the next call, the excavation responsibility, and who may pay for the work. In practical terms, a leak between the meter and the house usually routes to a licensed plumber. A leak on the utility side of the meter, in the street, or in public infrastructure should go to the water provider.

That rule isn’t universal in every detail, so let the utility confirm its responsibility before authorizing private work. Columbus’ customer guidance specifically distinguishes leaks on the property’s plumbing line from leaks the utility can inspect or service. The point isn’t to memorize another city’s policy. The point is to ask your own utility where its ownership stops.

Two examples make the split clear

A soggy patch halfway up the front lawn, with the meter still moving and no sprinkler cycle running, usually sends the call to a plumber. The buried line from the meter to the house is private in many residential layouts, and the plumber can diagnose, excavate, repair, or recommend main water line repair or water line replacement.

A meter box that repeatedly fills with clean water is different. Call the utility first and ask them to inspect the meter and the supply side. If the utility confirms the leak is private, you then have a useful diagnosis for the plumber instead of paying someone to investigate equipment the utility controls.

The expensive mistake is not waiting a few minutes to identify the side of the meter. It’s authorizing excavation before ownership is clear.

The same decision applies in Woodstock, Acworth, Alpharetta, Canton, Roswell, Marietta, Cumming, and Johns Creek. Local boundaries can vary across Cobb County, Cherokee County, North Fulton, Forsyth County, and the wider Metro Atlanta area, so use the utility as the first checkpoint when the leak is near the street or meter.

If the private line is confirmed, use a company that can explain whether a targeted leak repair, a full service-line repair, or water line replacement makes sense. Homeowners can review residential water line repair and replacement before scheduling an evaluation.

When You Need an Emergency Plumber Right Now

A wet lawn can wait for a scheduled diagnostic visit if the water is only dampening soil and the meter is stable after the appropriate shutoff. Flowing water, structural exposure, sewage, or rapid pressure loss can’t wait.

Call a 24 hour plumber when you see any of these conditions:

Water is surfacing and visibly flowing rather than merely pooling.
The meter keeps spinning with every fixture and valve in the house shut.
Water pressure drops at multiple fixtures.
A crawlspace is wet, or water is appearing through a slab.
Sewage is visible or strongly smells at the surface.
A sinkhole is forming along the suspected line.

If water is entering the home, shut off the main valve if you can do so safely. Keep away from electrical equipment in wet areas, and don’t enter a crawlspace where standing water may be present without addressing electrical hazards first.

Have the details ready before calling an emergency plumbing service. Give the address, nearest cross street, meter location, what the meter is doing, which valves you shut off, where water is surfacing, and whether 811 has been contacted. Those details help the dispatcher decide whether you need a burst pipe repair crew, a service-line technician, or a sewer specialist.

Ask one direct question: “Does the technician handle yard service-line repair, or do you send a re-route specialist?” A repair may involve excavation and replacement of damaged pipe. A re-route may be considered when access, landscaping, or existing underground conflicts make the original path impractical.

Emergency pricing depends on the type and timing of the problem and local rates. Industry summaries report flat emergency visit fees of about $100 to $350, while another summary says emergency fees can add roughly $300 to $400 to plumbing repairs. Review emergency plumber cost factors, then ask for the service-call terms before work begins.

A Real Yard Leak Walkthrough in Metro Atlanta

A homeowner in Cobb County notices a soggy patch and a small stream near the water meter on a quiet Sunday afternoon. Every faucet is off, but the meter dial is still moving. That combination suggests a continuous leak, but it doesn’t yet prove whether the utility or homeowner owns the failed section.

The homeowner shuts off the house-side valve, keeps people away from the wet ground, and takes photos. Next comes the call sequence:

Call 811 before digging. Give the address and explain that a water-line repair may be needed. The locator marks buried utilities so nobody excavates into a gas, power, telecommunications, or water line.
Call the county or municipal water authority. Provide the account number, address, nearest cross streets, meter location, and the fact that the meter still moves with fixtures off.
Describe the surface evidence. Tell the utility whether the water is clear, whether it is inside the meter box, and whether it is flowing toward the street or house.

The utility may inspect the meter and its side of the connection. If the crew finds a utility-side leak, the water authority handles that portion. If the meter and public-side piping are sound, the homeowner calls a licensed plumber to inspect the service line running toward the house.

What the handoff should look like

The best outcome is a clean handoff, not a callback loop. The utility confirms where its responsibility ends, the plumber works on the private line, and 811 markings guide the excavation. The homeowner can then ask whether the damage calls for a focused repair, a longer section replacement, or a reroute around a conflict.

This same process fits homeowners searching for main water line repair near me, water line replacement in Acworth, or an emergency plumber in Marietta. The city name changes the provider, but the meter-side decision stays the same.

A sewer backup requires a different response. Ohio EPA says rain-event backups can result from excess water overwhelming capacity, public sewer blockages or failures, or a clogged house-to-main lateral. Downspouts, foundation drains, and sump pumps connected to sanitary sewers can also push stormwater back into a home during storms, as explained in Ohio EPA’s sewage backup guidance.

Quick Reference Checklist for Next Time

Save this decision tree on your phone. It works as a quick field card when the yard is wet and you need the right call without guessing.

Stabilize first

Protect people and pets: Keep everyone away from unstable soil, foul water, and wet electrical areas.
Stop irrigation: Turn off sprinkler zones and outdoor fixtures that could be feeding the area.
Close the house-side valve: Shut off the main only if you can reach it safely.
Document the scene: Photograph the wet patch, meter, pooling, erosion, and nearby foundation.

Locate the leak

Check the meter: Confirm whether the flow indicator moves while all water use is stopped.
Inspect visible clues: Look for greener grass, mud, hissing, meter-box water, sinkholes, or sewage odor.
Mark the route: Identify the path from meter to house and note where public property begins.
Call 811 before excavation: Get buried utility lines marked before any digging.

Choose the caller

Water utility: Call for suspected meter-to-main, street, or public-side leaks.
Licensed plumber: Call for private-side service lines, exterior leak repair, sewer repair, or concealed plumbing.
Irrigation technician: Call when a sprinkler lateral, valve, or timer-controlled zone is the source.
Emergency plumber: Escalate for flowing water, sewage, foundation exposure, major pressure loss, or a forming sinkhole.

Check your meter readings periodically so unusual use stands out early. Have the irrigation system inspected when starting it for the season, especially if a zone produces muddy ground or pooling. The right-first-call habit saves time, protects the property, and keeps a simple ownership question from turning into an unnecessary excavation.
