Water Leak Before or After the Meter: Who Is Responsible and Who Pays?
Your water bill has soared for no apparent reason, or you notice a leak in your building? The first question to settle is whether the leak is located before or after the water meter. This distinction, simple as it seems, entirely determines who is responsible for the repair and who bears the costs. Here is a complete overview for Paris residents, whether you are an owner or a tenant.
Where does the line of responsibility lie?
The water meter constitutes the legal and technical boundary between two distinct zones of responsibility:
– Upstream of the meter (street side): the pipe is part of the public network, managed by the water utility (Eau de Paris in the capital).
– Downstream of the meter (home side): the pipes are private and fall under the responsibility of the subscriber, whether they are an owner-occupier, landlord or apartment building.
The meter itself generally belongs to the water utility, which handles its maintenance and replacement. The stopcock located just after the meter marks the start of the subscriber's responsibility.
Special case: Parisian apartment buildings
In a multi-unit building, the situation has an additional layer:
– The riser (vertical pipe supplying the floors) is a shared area, under the apartment building's responsibility.
– The individual connection, from the branch off the riser to the flat's taps, is a private area, under the responsibility of the occupant or the owner.
The building regulations usually specify this allocation. In case of doubt, they serve as the reference.
Leak before the meter: the public network
Who is responsible?
A leak upstream of the meter concerns the service pipe between the public network (under the road) and the building or property's meter. This section falls under the responsibility of the water network operator.
In Paris, Eau de Paris handles this. The repair is at their cost, at no charge to the subscriber.
How to spot it?
– Visible water flow on the pavement, at the foot of the building or in the meter room.
– Clear water seeping continuously, regardless of consumption inside the property.
– The meter is not turning even though flow is visible (confirming the leak is upstream).
What to do?
– Report the leak to Eau de Paris (phone or online form). The operator is required to intervene as promptly as possible.
– Do not attempt to repair it yourself: the service pipe is under pressure and requires professional intervention on public land.
Leak after the meter: the subscriber's responsibility
The principle
Any leak occurring downstream of the meter is the responsibility of the water contract subscriber. This includes:
– Pipes between the meter and the property.
– Interior pipes within the property (under the sink, inside walls, under floor tiles).
– Connections to sanitary appliances (toilet, bathtub, shower, washing machine, dishwasher).
– Taps and stopcocks.
Warning signs
– The water meter is turning even though all taps are closed and no appliance is using water. For more on this diagnostic, see our article: Water meter turning: hidden leak?
– A damp patch appears on a wall, ceiling or floor.
– The water bill increases abnormally without any change in habits.
– A continuous running water sound is audible in the walls or floor.
Who to call?
A qualified plumber is the right professional to locate and repair a leak after the meter. In a Parisian apartment building, the building manager must be notified in parallel, especially if the leak affects shared areas or a neighbouring flat. For guidance on who to contact in case of water damage in an apartment building, see our guide: Water damage in a Parisian apartment building.
Tenant, owner, apartment building: who pays for what?
The allocation of costs for a leak after the meter depends on the occupant's status and the origin of the leak.
The tenant is responsible for:
– Routine maintenance of taps, seals, flexible hoses and flush mechanisms (decree of 26 August 1987 on tenant repairs).
– Replacing seals, valves and small wear parts.
– Repairing a leak caused by a lack of routine maintenance.
The owner (or landlord) is responsible for:
– Replacing worn-out or faulty pipes.
– Repairing a leak caused by a structural defect (pipe corroded through, faulty fitting installed before the tenant moved in).
– Destructive leak detection work (opening a wall, removing floor tiles).
The apartment building is responsible for:
– Leaks on shared areas: risers, horizontal pipes in the basement, riser base valves.
– Leak detection on shared areas.
– Repairs on the riser, even if the leak impacts a specific flat.
In case of disagreement, the building regulations and the lease serve as the reference. Home insurance generally covers the damage caused by a leak (water damage), but rarely the repair of the leak itself. For more on insurance coverage, see our article: Leak detection in Paris and insurance coverage.
Water bill adjustment: a right under certain conditions
When a leak after the meter causes excessive water consumption, the subscriber can request an adjustment (reduction) of their water bill. This right is governed by the Warsmann law of 17 May 2011 (Article L. 2224-12-4 of the French General Local Authorities Code).
Conditions to meet
– The leak must be on a pipe after the meter (leaks from household appliances, taps or toilet cisterns are excluded).
– The leak must have been repaired by a professional.
– The subscriber must send the repair certificate to the water utility within one month of being notified of the excess consumption.
How the adjustment is calculated
The water utility only charges up to double the usual average consumption (calculated over the previous three years). The excess beyond this threshold is cancelled, on both the water and sewerage portions.
Practical steps
1. Have the leak repaired by a qualified plumber.
2. Obtain a repair certificate stating the nature and location of the leak, the repair date and the professional's details.
3. Send this certificate to Eau de Paris (by post or online form) within the required timeframe.
4. The adjustment is applied to the next bill or issued as a credit note.
What to do immediately in case of a leak
Regardless of the leak's location, the first steps are the same:
1. Turn off the water: close the stopcock nearest to the leak (under-sink valve, flat stopcock, or the building's main valve if necessary).
2. Protect your belongings: move exposed items and furniture, mop up standing water.
3. Identify the zone: check whether the leak is before or after the meter (is the meter turning with all taps closed?).
4. Notify the relevant parties:
– Leak before the meter: contact Eau de Paris.
– Leak after the meter in a private area: contact a plumber.
– Leak affecting shared areas or a neighbour: notify the building manager and declare a claim to your home insurance.
5. Document everything: take photos of the leak and any damage for the insurance file.
6. Don't delay: even a minor leak can cause significant damage if left untreated (wall infiltration, subsidence, mould).

Frequently asked questions
Who pays for a leak before the meter?
The water network operator (Eau de Paris in the capital) covers the repair of leaks upstream of the meter, at no cost to the subscriber. This section of pipe is part of the public network. The subscriber simply needs to report the leak to trigger the intervention.
Can you get a bill adjustment for a leak?
Yes, the Warsmann law provides for an automatic adjustment when a leak on a pipe after the meter has caused abnormal excess consumption. The subscriber only pays up to double their usual consumption; the excess is cancelled. To qualify, you must have the leak repaired by a professional and send the repair certificate to the water utility within one month.
Leak in a wall: tenant or owner?
It depends on the cause of the leak. If it comes from a seal or fitting whose routine maintenance falls to the tenant (tenant repair), the tenant bears the cost. If it results from an ageing embedded pipe (corrosion, structural defect), the cost falls to the owner. In an apartment building, if the affected pipe is a shared area (riser), the apartment building pays. In practice, a diagnosis by a qualified plumber is often needed to determine responsibility.
