Permit applications
Connection to municipal services (sewer and aqueduct)
Any new connection to the municipal water and sewer system must comply with current standards to ensure a safe and compliant connection. A permit is required before any work is carried out, whether it involves new construction or a connection to an existing network.
Rehabilitation of private network (sewers and aqueducts)
The replacement or repair of water and sewer pipes on private property must be carried out according to strict rules to avoid leaks, backups and water contamination. A permit is required for any work on these infrastructures.
Septic tank
The installation or replacement of a septic tank must meet environmental and public health requirements. A permit is required to ensure that the installation is properly sized and complies with current standards.
French drain
Installing or repairing a French drain is an effective way of evacuating groundwater and preventing water infiltration into foundations. A permit is required to ensure compliance and avoid the risk of accumulation or inappropriate redirection of drainage water.
Best practices and advice
For compliant, sustainable work on water and wastewater networks, we recommend that you follow these best practices:
- Call on certified professionals: work on sewer, water or septic systems requires specialized skills to ensure compliance and efficiency.
- Ensure proper drainage: inefficient drainage can lead to water infiltration and moisture problems. A well-designed and maintained French drain protects your property.
- Opt for durable materials and equipment: choose pipes and fittings that are resistant to corrosion and climatic variations, to ensure a longer service life for your installations.
- Respect the neighborhood and the public highway: when connecting or repairing a network, inform your neighbors and make sure you don’t obstruct traffic or access to adjacent properties.
