Environmental Protection Louisiana 4 Minutes Read ยท published February 09, 2026 Flag of Louisiana

In New Orleans, Louisiana property owners must follow municipal rules for connecting to stormwater and sanitary sewer systems. This guide summarizes who is responsible for lateral connections, when permits are required, common violations, and how enforcement works under the city code and the Sewerage and Water Board. It is intended for homeowners, landlords, and contractors doing work that affects drainage or sewer connections. Read the permit and inspection steps carefully and keep records of approvals and contractor work to avoid fines and costly repairs.

Overview of Rules and Responsibilities

Owners are typically responsible for the private sewer lateral from the building to the public main and for ensuring stormwater controls meet city requirements. Public mains and in-street infrastructure are managed by the Sewerage and Water Board of New Orleans (SWBNO), while permits and inspections are administered through the city's permitting office.

Key governing text is in the City of New Orleans Code of Ordinances; check the municipal code for exact provisions and definitions City Code of Ordinances[1].

Connection Types and When Permits Are Required

  • New sanitary sewer lateral connections: require a permit and inspection prior to concealment.
  • Stormwater discharge changes or new outfalls: usually require review and approval under city stormwater rules and possibly SWBNO consent.
  • Emergency repairs: notify the permitting authority as soon as practicable and obtain retroactive inspections if required.
Always obtain required permits before starting work on laterals or storm connections.

Penalties & Enforcement

Enforcement is carried out by the City of New Orleans through its permitting and code enforcement units and by the Sewerage and Water Board for infrastructure under its control. Specific fine amounts and escalation schedules are stated in the municipal code or agency rules where available; if an exact figure is not listed on the cited page, it is noted below.
