Blocked drains, sewers or gullies
Who looks after drains and sewers?
Drains on private land that only serve that property are the responsibility of the property owner.
A drain which serves only your property but is located on someone else's land is the responsibility of the sewerage undertaker.
Public sewers are managed by the sewerage undertaker, eg Southern Water. This includes public sewers and lateral drains (drainage pipes that connect a property to the main sewer but are located outside the boundary of that property).
Privately-owned septic tanks and cesspits are the responsibility of the property owner.
Maintaining private drains
If your drain is blocked you may notice water draining away slowly, gullies outside overflowing or an unpleasant smell.
Drains can become blocked for a number of reasons, but you can help prevent blockages by being careful about what goes down your drain:
- Avoid flushing items such as nappies, wet wipes and cotton buds down the toilet
- Cooking oils or fats which are poured down the sink will solidify in the pipes - put cooled fats and oils in a container and then put it in your bin
- Use strainers in the sink to collect food waste particles
