Dublin Sewer Connection Consent - Bylaw Guide
In Dublin, Leinster, connecting a property to a public sewer requires consent from the relevant water authority and compliance with municipal byelaws and codes of practice. This guide explains who grants consent, which forms are used, the inspection and enforcement routes, and typical steps for homeowners, builders and developers. It summarises official application channels, the enforcing departments, and practical actions to apply, pay fees, respond to notices and appeal decisions.
Who is responsible
Responsibility is shared between Irish Water (the national water utility) for network approvals and the local municipal authority for on-street infrastructure, bylaws and enforcement. For city-specific queries contact the local council drainage or building control office and Irish Water for connection permissions and technical approvals. For developer or technical enquiries use the official Irish Water application channels below and the Dublin City Council guidance on drainage and sewer works.Irish Water - New Connections[1] Dublin City Council - Drainage & Sewers[2]
