About Liverpool One Drainage: Practical Drainage Engineering Across Liverpool & Southport
When an external gully is overflowing with foul waste or a toilet backs up on a Sunday evening, you do not want a national call centre or a subcontractor turning up with a basic hand plunger. You want an experienced local engineer with a properly kitted van who can clear the line, put a camera down to check why it blocked, and give you a straight answer on the spot.
Direct local response from our Liverpool & Southport hub—no franchise middlemen or hidden call-out fees.
Who We Are & How We Work
Liverpool One Drainage is an independent drainage firm built on more than 30 years of hands-on trade experience. Operating from our base in Liverpool & Southport, we look after domestic homeowners, commercial landlords, facilities managers, and home buyers across Merseyside and West Lancashire.
Many drainage call-outs end up being recurring headaches because the first person on site only poked a hole through a soft blockage and drove off. If a drain blocks repeatedly, there is almost always a physical reason underground: a displaced salt-glazed clay joint catching wet wipes, fine tree roots creeping through old mortar collars, heavy grease buildup from a kitchen run, or ground movement causing a belly in the pipework.
We treat every job as an engineering problem rather than a quick dash. Our vans carry commercial-grade high-pressure water jetting rigs, mechanical root cutters, self-levelling HD CCTV crawler and push-rod cameras, sonar tracing sondes, and CIPP (Cured-In-Place-Pipe) resin relining gear. That means we can clear the immediate flood, inspect the pipe wall in real time with you watching the monitor, and carry out a permanent structural repair without unnecessary digging.
Time-served experience diagnosing and repairing underground drains.
Round-the-clock emergency response for overflowing gullies and blocked sewers.

Local Ground Knowledge Matters
Merseyside has a huge mix of drainage infrastructure. In older parts of Liverpool such as Wavertree and Anfield, deep brick-built shared rear alleyway runs and Victorian clay rest bends frequently suffer from root ingress and dropped joints. Further up the Sefton coast around Crosby, Formby, and Southport, shifting sandy subsoils and high water tables can cause pipe settlement if a joint starts leaking. Knowing what lies beneath the tarmac or patio before lifting a manhole lid saves our customers hours of guesswork.
What We Do (And What We Don't)
We are dedicated drainage specialists—not general plumbers, boiler installers, or odd-job builders. By sticking strictly to underground and internal foul and surface water drainage, we invest properly in the heavy plant and diagnostic technology required to fix drains first time.
Emergency Drain Unblocking
Clearing blocked toilets, sinks, external yard gullies, soil stacks, and main chamber runs using controlled high-pressure water jetting (HPWJ) that strips away fatbergs, wet wipes, and scale without damaging older clay pipe walls.
CCTV Surveys & Sonar Tracing
Live HD camera inspections to pinpoint cracks, root ingress, or collapsed pitch-fibre pipes. We provide full pre-purchase home buyer drainage reports and use sonar sondes to mark out exact pipe depths and routes above ground.
No-Dig Relining & Patch Repairs
Structural CIPP resin sleeves and silicate patch packers that seal open joints, fractures, and root intrusions from inside the existing pipe—saving you the cost and disruption of breaking up driveways, extensions, or landscaped gardens.
Excavation & Chamber Rebuilds
When a sewer has completely collapsed or back-pitched beyond relining, we carry out safe trench excavations, replace perished runs in modern plastic or clay, rebuild crumbling brick manholes, and reinstate your paving cleanly.
Commercial PPM & Descaling
Planned preventative maintenance for restaurants, hospitality venues, offices, and industrial estates. Includes out-of-hours high-pressure stack descaling, car park silt clearance, and commercial kitchen grease trap servicing.
Drain Pest Control & Rat Blockers
Rats frequently enter cavity walls and kitchens via redundant branch lines or uncapped inspection chambers. We trace the entry point by camera and install marine-grade stainless-steel non-return rat valves inside your manhole chamber.
Why Homeowners & Businesses Choose Us
Having raw sewage backing up onto your patio or inside a commercial premises is stressful enough without dealing with vague pricing or messy workmanship. Everything we do on site is designed to get your drains flowing, show you the evidence, and leave your property sanitised.
Clear Upfront Quotes Before Work Starts
We do not charge hidden call-out fees or surprise per-half-hour rates. Once we inspect the chamber and see what is needed, we give you a clear, fixed price for clearing the blockage or repairing the pipe before we start the job.
Show-Not-Tell Camera Diagnostics
We never ask you to take our word for an underground fault. When we run our CCTV camera down the line, we invite you to look at the live high-definition monitor so you can see any displaced joints, root masses, or fractures for yourself—and see the clean, lined pipe once we finish.
Strict Site Hygiene & Property Protection
High-pressure hoses and foul waste require careful handling. We protect lawns, block paving, and internal flooring, contain any overflow spills, wash down and disinfect affected external gullies and patio areas, and make sure inspection chamber covers are seated safely and level before leaving.
Honest Advice on Private vs Public Sewer Boundaries
Under the 2011 sewer transfer rules, many shared lateral drains and pipes outside property boundaries in Merseyside are the responsibility of United Utilities rather than the homeowner. If we trace a blockage or collapse onto the public sewer network, we will tell you straight away so you do not pay privately for work the water board should handle.
