Septic Tank Emptying
KEEP YOUR TANK
FLOWING FREELY
At SWM Drainage, our experienced technicians provide professional septic tank emptying and cesspit cleaning throughout Oxfordshire. Whether you need a routine empty, a full tank assessment, or emergency cesspool emptying, our licensed team handles it all — safely and in compliance with Environment Agency regulations.
As a general guideline, septic tanks should be emptied every 1–3 years and cesspits more frequently depending on usage. Regular cesspit cleaning and septic tank emptying across Oxfordshire prevents costly repairs and keeps your system running efficiently all year round.
Unpleasant smells around drains or the tank area often signal it's time for an empty.
Sluggish sinks, baths and toilets can indicate your tank is reaching capacity.
Unexplained waterlogged areas near the tank suggest overflow or leaking.
Suspiciously green grass above the tank can indicate a leak underground.

BLOCKED?
WE'LL CLEAR IT

We provide professional drain unblocking and gully emptying across Oxfordshire seven days a week, with no call-out charge for quotes.
We serve properties across Oxfordshire seven days a week, ensuring you’re never left waiting when a drainage emergency strikes.
Our Techniques
Powerful jetting clears even the most stubborn blockages and thoroughly cleans pipe walls.
Mechanical scouring removes built-up debris, grease and root intrusion effectively.
Camera inspection to identify cracks, wear, root ingress and broken sections.
Planned maintenance to prevent blockages before they become costly emergencies.
Warning Signs
SPOT THE SIGNS OF A BLOCKED DRAIN
If water rises in the toilet bowl when you flush rather than draining, there's likely a blockage below.
Standing water that won't drain from your bath or shower is a clear sign of a blockage.
Foul odours rising from drains indicate trapped organic matter that needs clearing.
A pool of water forming near your sink or toilet warns that your drainage needs urgent attention.
If water won't drain from any fixture — bath, sink or shower — the drain is likely fully blocked.
Water escaping below the toilet pan after flushing indicates a serious blockage or pipe issue.
