A gully is the drain at ground level that takes water away from your yard, driveway or the base of a downpipe. Guttering sits up on the roofline, catching rainwater before it reaches the ground. Mix the two up and you’ll end up booking the wrong job.
We get asked about the difference most weeks. A gully sits at ground level, usually against an outside wall, near a downpipe or under a drain cover in the yard. Water, leaves and grit wash into it, and the gully carries everything down into the drainage system below. Guttering is a separate job in a separate spot, the channel running along your roof edge that catches rain off the tiles before it ever reaches the ground.
Drainage gully types vary from property to property, but a yard gully set into a driveway or patio is the one most people have. Whatever the layout, the job is the same: catch the water at ground level and take it into the system.
This is where people go wrong. Water pooling by the back door after rain often gets blamed on the gutters, when it’s actually the gully underneath that’s clogged. Check what’s happening at ground level before you call anyone out to clear guttering three storeys up.
We see this a lot on older properties around King’s Lynn, where the gully trap is often the original one and the grid’s half buried under years of leaf mulch and moss. If you’re standing over a grid looking at black sludge and a smell that’s not doing anyone any favours, that’s a blocked gully drain.
The gully outside your own property is yours to look after. A gully out in the road or pavement, sometimes called a highway gully, belongs to the council instead. If you’re ever unsure which one you’ve got, gov.uk has a page on reporting a blocked drain that points you to the right place.
A gully drain doesn’t fail overnight. It gives you a warning first, if you know what to look for. Water sitting around the grate after rain is the big one. A smell coming up from outside is another, especially near a kitchen door or bin store.
Most people don’t call it a gully until we tell them what it’s called. They just know they’ve got a blocked outside drain, or a blocked drain outside the house that keeps coming back. It’s the same problem either way, a blocked gully that needs clearing before it gets worse.
We get called out across King’s Lynn after weeks of someone hoping it’ll sort itself out, then a heavy downpour turns a slow drain into standing water across a yard or car park.
West Norfolk sits on low fenland with a high water table, so a gully that’s already struggling has less room for error once the ground is saturated. We see this every week during a wet spell. A gully that’s been half blocked for months suddenly can’t cope, and water starts creeping towards a doorway or car park entrance. Usually it’s just silt in drains building up gradually along with leaves and grease. Nothing dramatic, just neglect.
Spot it while it’s still just pooling and it’s a much smaller job to sort. Leave it through another wet month and the blockage backs up further, sending water across more of the yard or car park each time it rains. Gully work is one part of our emergency drainage service in King’s Lynn.
A gully that’s slow but still draining, with just leaves and grit sat in the trap, is usually one you can sort yourself. Lift the grate, scoop out the muck with a trowel, bag it and bin it, then flush it through with a bucket of water. That’s gully emptying at its simplest, job done, no faffing about.
It gets trickier once the gully’s full to the top and not moving at all, or when water’s backing up into a yard or under a door. That’s no longer a scoop-and-go job. If the same gully keeps blocking every few weeks in the same spot, something further down the pipe is usually the real cause, and that calls for proper external drain unblocking rather than another go with a trowel.
Once you’ve cleared the trap and it’s still backing up, that’s the point to stop DIY-ing it. Our high-pressure jetting and CCTV drain surveys find a blockage further down the pipe, or root ingress inside it, rather than leaving it to guesswork, and clear it in the same visit.
Right, here’s what a proper gully cleaning job looks like when we turn up. There’s a set order to it, and skipping steps is why some gullies end up blocked again a few months later.
That CCTV step is the bit most people skip when they try to sort it themselves, or when someone just jets it and drives off. A gully that keeps blocking usually just needs a proper clean like this, done in full.
Every so often, though, the camera finds the pipe run itself has an issue. If it’s a collapsed section, that’s drain repair and excavation, a different job, and we can quote it once we’ve seen what’s down there.
West Norfolk is a mixed bag. Village houses out past Terrington St Clement run off septic tanks. Restaurant kitchens in King’s Lynn are tied into mains drainage with a grease trap outside. Both need their gullies looked after, but for different reasons.
On a rural, off-mains property, the gully outside your kitchen or utility room often feeds towards a septic tank or treatment plant. Let that gully silt up with leaves and grit, and less flow gets through to the tank. We do septic tank pumping and septic tank maintenance across these fenland villages, and a blocked gully upstream just adds pressure to a system that’s already working hard on flat, low-lying ground.
Commercial kitchens are a different story. A gully near a back door or loading bay picks up fat, food scraps and wash-down water all day. Usually it’s grease building up where it shouldn’t, which is why commercial gully cleaning gets tied into any grease trap job for a restaurant, pub or takeaway, done at the same time rather than left for later. Miss it and you’re looking at a smell out the back, or standing water right where staff and deliveries walk through.
Whether it’s a rural cottage, a care home kitchen or an industrial unit, the approach is the same: work out which system the gully feeds, a septic tank or a grease trap, and clean it accordingly.
A blocked manhole is a different job from a gully, even though the two get confused because both sit outside at ground level. A manhole covers the point where several drain runs join before heading off towards the main sewer.
People describe the same underlying problem in different ways: an outside drain blocked further down its run, a blocked drain outside the house that keeps coming back, or a manhole that won’t stop backing up. It usually comes down to where the blockage actually sits.
Whose job it is also depends on which side of the boundary that section sits on. Once a drain run leaves your property and joins the wider network, it can shift from being your responsibility to Anglian Water’s. Their guidance on sewer and drain responsibility sets out where that line usually falls.
External drain unblocking generally follows the same approach as any other blocked drain: lift the cover, see what’s happening in the chamber, and clear it with rodding or jetting depending on what’s found. If the cause isn’t obvious, running a CCTV camera through checks the pipe for root ingress, a collapsed section, or a blockage further along the run.
We cover manhole cleaning and outside drain cleaning across King’s Lynn and West Norfolk, on domestic properties and on commercial sites with more than one manhole feeding into the system.
Common questions about Gully Cleaning, Manhole and Drain Clearance in King’s Lynn.
A gully sits at ground level and takes water from your yard or downpipe. Guttering is up on the roofline, catching rain off the tiles. If you’ve got water pooling by the back door, the gully’s usually the one to check first. We see this mix-up often, particularly on older properties in King’s Lynn with an original gully trap hidden under a grid.
Yes, if it’s just slow draining with leaves and grit in the trap. Lift the grate, scoop the muck out with a trowel, bag it and flush it through with a bucket of water. That’s straightforward gully emptying. If the gully’s full to the top and not moving, or water’s backing up into your yard, that’s past a DIY job and it’s worth calling us instead of making it worse.
This usually means there’s a problem further down the pipe, not just surface muck. Root ingress or a structural issue in the drain run causes repeat blockages, even after you’ve cleared the trap yourself. We carry jetting and CCTV equipment on every van, so we can find and clear the actual cause on the first visit instead of guessing.
West Norfolk sits on low fenland with a high water table, so a gully that’s already half blocked has less room to cope once the ground gets saturated after rain. We see this every week during wet spells. A gully that’s coped fine all summer can suddenly back up during a heavy downpour.
Gully cleaning starts with lifting the grid and clearing the loose debris by hand, or with a vacuum tanker if there’s a lot to move. High-pressure water jetting goes in next to break up compacted silt and grease on the sides. We flush it through and check the water’s draining away properly, and if it’s still slow, we’ll check further down the pipe rather than leaving it half done.
It’s often grease build-up or standing water that’s gone stagnant, especially near a kitchen door or bin store. If the smell comes back within days of clearing it yourself, that usually points to grease or root ingress rather than surface debris. A sewage smell near a commercial kitchen is worth calling us about straight away.
If the gully is on your own property, driveway or yard, it’s yours to sort and we can clear it. Gullies out in the road or pavement are highway gullies, and those are the council’s to maintain, not yours. If you’re not sure which you’ve got, gov.uk has a page on how to report a blocked drain, which will point you to the right place.
