Septic Tank Emptying
KEEP YOUR TANK
FLOWING FREELY
At SWM Drainage, our experienced technicians provide professional septic tank emptying and maintenance across Oxfordshire. All liquid waste is disposed of safely and in accordance with standard regulations. We serve both domestic customers and small businesses.
A general guideline is to have your septic tank inspected and emptied every 3 to 5 years. Regular maintenance helps prevent costly repairs and ensures your system operates efficiently.
Foul Odours
Unpleasant smells around drains or the tank area often signal it’s time for an empty.
Slow Drains
Sluggish sinks, baths and toilets can indicate your tank is reaching capacity.
Pooling Water
Unexplained waterlogged areas near the tank suggest overflow or leaking.
Lush Lawn Patches
Suspiciously green grass above the tank can indicate a leak underground.
Drain Unblocking
BLOCKED?
WE’LL CLEAR IT
FAST
Whether it’s a blocked kitchen sink, a flooded bathroom, an overflowing manhole or a commercial drainage issue — SWM Drainage has the skills, tools and experience to clear any blockage.
We serve properties across Oxfordshire seven days a week, ensuring you’re never left waiting when a drainage emergency strikes.
Our Techniques
01
High-Pressure Drain Jetting
Powerful jetting clears even the most stubborn blockages and thoroughly cleans pipe walls.
02
Electro-Mechanical Cleaning
Mechanical scouring removes built-up debris, grease and root intrusion effectively.
03
CCTV Drain Survey
Camera inspection to identify cracks, wear, root ingress and broken sections with precision.
04
Preventive Maintenance
Planned maintenance services to prevent blockages before they become costly emergencies.
Warning Signs
SPOT THE SIGNS OF A BLOCKED DRAIN
01
Rising Water After Flushing
If water rises in the toilet bowl when you flush rather than draining away, there’s likely a blockage in the drain below.
02
Stagnant Bathtub Water
Standing water that won’t drain from your bath or shower is a clear sign of a partial or full blockage.
03
Putrid Smells from Drains
Foul odours rising from drains indicate trapped organic matter or waste buildup that needs clearing.
04
Water Pooling on Floors
A pool of water forming near your sink or toilet is a warning that your drainage system needs urgent attention.
05
Water Won’t Flow Away
If water simply won’t drain from any fixture — bath, sink or shower — the drain is likely fully blocked.
06
Water Escaping at Base
Water escaping below the toilet pan after flushing indicates a serious blockage or pipe issue requiring immediate help.
