Understanding who is responsible for different parts of the drainage system can help you resolve issues quickly and effectively. Below is a guide to help you determine your responsibilities and who to contact.
What’s the Difference Between a Drain and a Sewer?
- Drain: A pipe that serves a single property and carries wastewater and sewage to a sewer. Homeowners are responsible for the maintenance and repair of drains within the boundary of their property.
- Lateral Drain: The section of pipe that carries waste away from your property but lies outside your boundary, often beneath a pavement or road. This is typically the responsibility of United Utilities.
- Sewer: A pipe that collects waste from more than one property. Shared sewers are the responsibility of United Utilities, even if they are within your boundary.
Homeowner Responsibilities
If you experience a blocked or damaged drain that serves only your home and is within your property boundary:
- You are responsible for arranging repairs or unblocking.
- You can contact a professional drainage contractor or check if your home insurance covers this under your buildings policy.
Shared Drains and Sewers
If you are connected to a shared drain or public sewer, United Utilities is responsible for maintenance and repairs, even if the pipe runs through your garden or driveway.
For issues with shared drains or sewers, please contact United Utilities unitedutilities.com
Septic Tanks and Private Drainage
If your property is served by a septic tank or a private drainage system (shared or not), maintenance remains the responsibility of the property owners who use it. United Utilities do not manage septic tanks or private drainage systems.
For problems with septic tanks, please:
- Contact a specialist drainage company that maintains septic tanks, or
- Check if your home insurance covers the issue.
Road Gullies
Blocked or damaged road gullies (the grates at the edge of the road that drain surface water) are the responsibility of Lancashire County Council Highways – Drains and Sewers – Lancashire County Council
