An outside drain may look simple, but responsibility depends on where it is, what it serves and whether it connects to a shared drainage route.
The most useful first step is to look at the pattern: what is affected, when it happens, whether the issue is inside or outside, and whether it has happened before.
Quick checks
Use these quick checks to understand the issue:
- Whether the drain is on private land
- Whether it is in the road or highway
- Whether internal fixtures are affected
- Whether neighbours are affected
- Whether water is sewage or rainwater
- Whether an inspection chamber is overflowing
What the symptoms can tell you
Private outside drains
An outside drain or gully serving one property is often part of that property’s private drainage system.
Shared drains and public sewers
If the drain connects into a system serving more than one property, responsibility may differ.
Road gullies and highway drainage
Drains in the road and highway drainage points are usually handled separately from domestic drainage.
When further investigation or help may be needed
Drainage support or CCTV investigation may be useful when symptoms keep returning or the cause is unclear.
- Water is backing up or overflowing
- More than one fixture is affected
- Bad smells or gurgling are present
- The same issue keeps returning
- An outside drain is involved
- The cause is unclear
Useful information to include in the enquiry
A short, practical summary helps the enquiry be understood quickly.
- Your postcode

Common causes and practical indicators
Gradual build-up
Grease, silt, scale, wipes or everyday debris can reduce flow over time.
Local restriction
One affected fixture can point to a blockage close to that outlet.
Wider blockage
Several affected fixtures can suggest a restriction further along the run.
Root or pipe damage
Recurring symptoms may need CCTV investigation to understand the cause.
Shared drainage
Neighbouring properties or shared chambers can change the likely next step.
