Sanitation of domestic wastewater

Verified 12 July 2022 - Directorate for Legal and Administrative Information (Prime Minister)

The purpose of sanitation is to collect, discharge and treat waste water: sewage (water from the toilet) and gray water (water from the kitchen, washing machine...). It can be collective or all-sewer) or individual with a septic tank.

What is the role of the municipality in the management of the different types of sanitation? How is it funded? Who to contact in case of conflict?

We answer your questions.

Collective

Your house is connected to the communal network, the whole sewer. The sewer is connected to a collector which leads the waste water to the treatment plant. They are treated with stormwater, or separately.

The municipality is responsible for collecting domestic waste water and storing, purifying and discharging or re-using all the collected water.

The choice of setting up collective sanitation depends on the municipality.

You have the possibility to consult in town hall on drainage area which delineates areas of collective and non-collective sanitation.

Who shall I contact

In each municipality or group of municipalities there is a public sanitation service.

A public sewerage service regulation defines the services provided by the service and the obligations of the operator, users and owners. It is given to each user.

PSPC monitors the quality of the connection the municipal sewerage network. The check is carried out in the event of a new connection or a modification to an existing connection. He is valid for 10 years.

PSPC does not monitor the serviceability of the connection for which the owner is responsible.

If the dwelling is not connected or if the connection is not in conformity, the city hall can have the connection or the rehabilitation work carried out automatically at the owner's expense.

Dwellings which cannot be connected for technical reasons are controlled by the public non-collective sanitation service.

Since 1er january 2022, ec check is required in 71 communes of Île-de-France to improve water quality for freestyle and triathlon events 2024 olympic games. Owners are obliged to carry out the prescribed work within 2 years.

FYI  

since 1er july 2022, in case of sale of an item in one of these 71 municipalities, the document drawn up after the network connection check is attached to the technical diagnosis file (DDT) given to the purchaser.

Connection obligation

Connection is compulsory for buildings with access to the public sewage system. This access may be direct or via private roads or an easement under private land.

New construction

If the dwelling is built after the commissioning of the communal sewerage network, the connection must be made during the construction works of the dwelling.

Existing construction

You're two years old to connect an existing building. This period starts when the public network is put into service.

With the agreement of the prefect, the mayor can grant you a extension of connection periods within 10 years if you are in any of the following situations:

  • Construction permit granted for less than 10 years with a regulatory facility in good working order
  • Compliant individual remediation settled pending collective network implementation

If you are not subject to the connection obligation, you have the possibility to ask the City Hall for permission to connect you. Public domain network extension work is at your expense.

You will pay the community remediation charge and you may be subject to the community remediation financing (CCAP or CAP) participation.

How is the connection made?

The connection to the public sewage collector (sewer) includes work in the public domain and in the field of the building to be connected.

Work on the public domain

The work on the public part are in principle carried out by the sanitation service of the municipality. It establishes the connecting structures located under the public highway that extend until connection sanitation at the edge of the public domain.

The City Council may decide to implement the participation in connection costs which corresponds to the expenditure incurred in carrying out the public part of the work. It is paid for by all owners of the connected buildings.

Work on private property

You must perform the work on your private property. You choose the company that installs the necessary piping to drain the wastewater from the building to the public part of the connection. All this work is at your expense.

You can also ask the municipality to ensure the work to bring the private part into conformity. In this case, you will have to reimburse all costs incurred.

Buildings which are technically unsuitable for connection may be exempted from connection on condition that they have self-contained sanitation equipment. . This may be the case, for example, for a building located below a sewer.

You must send, on free paper, a request for exemption from connection to your town hall.

Who shall I contact

Buildings shall also be exempt from connection if:

  • Declared irremediably unsanitary with a permanent ban on residence
  • Hit by a perilous order ordering their demolition

As part of its task of monitoring the sanitation, the municipality can punish you if you do not respect your obligations.

Who shall I contact

In each municipality or group of municipalities there is a public sanitation service.

A public sewerage service regulation defines the services provided by the service and the obligations of the operator, users and owners. It is given to each user.

The service carries out compulsory inspection duties and provides optional maintenance, emptying or works. It checks the conformity of installations and connections. The user cannot choose another service provider to carry out the checks.

SPANC’s monitoring tasks shall consist of:

  • Review design proposals for new or rehabilitated facilities
  • Check job execution
  • Monitoring the proper operation and maintenance of existing installations

The frequency of monitoring visits to existing installations shall be defined by the municipality. It is specified in the service regulations and it cannot be longer than 10 years.

Buildings or houses not connected to the public sewage system must be connected to a public sewage system.

2 types of buildings are concerned:

  • Buildings located in non-collective sanitation areas
  • Buildings exempt from connection, in collective sanitation areas

You can do the work yourself. However, it is recommended to turn to a specialist company or to the municipality if it provides this service. They carry out all the work (earthmoving, digging, plumbing, connections...).

The municipality may lay down technical rules for the siting or refurbishment of installations. These rules concern in particular soil studies and the choice of the type of installation according to the permeability of the soil. Additional charges are the responsibility of the owner.

Before starting the work, you must submit your project to the public non-collective sanitation service (SPANC) of your commune. They can advise you on how to proceed and make recommendations for your project.

SPANC has the following missions:

  • Design Check of your future installation based on the study of your case
  • Write a regulatory compliance certificate that you will attach to your application for a building permit
  • Checks on proper implementation installation during a inspection of the site before filling.

You can rehabilitate your land after the SPANC's performance check.

The owner is responsible for the regular maintenance of his facility. The municipality may set up a service to ensure this maintenance. In this case, the owners choose to use a private company or the service set up by the municipality.

Draining shall be carried out by a company approved by the prefect. The frequency with which the all-water pit or the device to be emptied is emptied must be adjusted according to the height of the sludge, which in general must not exceed 50% of the useful volume.

The SPANC checks the proper operation and maintenance of the facility at least every 10 years. The frequency of the checks in your municipality is set out in the public sewerage service regulation.

Non-compliant installations must be subject to compliance work within 4 years, in case of proven health hazard or environmental risk.

FYI  

in case of sale, the owner is required to attach a visit report from the SPANC of less than 3 years to the file of real estate technical diagnosis. If the installation is non-compliant, work must be done within one year of sale.

The non-collective reorganization charge corresponds to a service rendered to the user who only pays for what concerns him. The fee shall include the costs of the SPANC's inspection missions and any costs of maintenance of the installation, which shall be charged according to the nature of the service.

As part of its task of monitoring the sanitation, the municipality can punish you if you do not respect your obligations.
