Blocked Drains in Arlesey
Blocked drain in Arlesey, cleared today
Jetting, rodding, root cutting and a camera down the line afterwards so you can see what caused it rather than take our word for it.
Vantage Plumbing and Heating reaches Arlesey and the rest of the SG15 district from Stevenage, up the A507 and A1(M) corridor. Two years on our workmanship, fixed pricing agreed before we start, and a 24/7 emergency line answered 365 days a year.
Clay ground, brick pits and two rivers: why Arlesey drains behave the way they do
Ground matters more than buildings in this trade, and the ground here is not simple.
Regional British Geological Survey mapping for the Biggleswade district puts this stretch of the Ivel valley on Gault Clay, with Lower Greensand of the Woburn Sands Formation below and to the east, and river terrace and alluvial deposits along the valley floor itself. Arlesey is not named individually in the summary we can cite, so treat that as the district pattern rather than a survey of your garden. We confirm what is actually there before we design anything that relies on it.
Two consequences follow.
The first is movement. Gault Clay swells when it is wet and shrinks when it dries, so the ground moves through the year. Buried drainage is rigid and jointed, and rigid jointed pipework in moving ground eventually opens up. Salt glazed clay with rigid joints, which is what sits under most property built before the 1950s, fails at the joints first: a slight displacement, a step in the invert, debris catching on the step, and a blockage that keeps coming back however often somebody rods it. Clearing it is not fixing it, and only a camera tells you which you have.
The second is drainage into the ground, or rather the difficulty of it. Clay does not soak away. Where surface water is supposed to disappear into a soakaway and the ground beneath is clay, it will not, and you get a soakaway that fills in November and stays full until April. If you are laying a driveway or a patio, or dealing with standing water in a garden, the infiltration rate is the number that decides the design, and on clay the answer is frequently attenuation and a proper outfall rather than a hole full of stone.
Then there is Arlesey’s own industrial history. This village made bricks in earnest, the Arlesey White, with five brickworks operating by 1900 and production running through to 1992, and the old chalk pits to the south are now the Blue Lagoon and the Green Lagoon. Ground on and around former extraction sites and made ground settles differently from undisturbed ground, and where drainage crosses it we treat differential settlement as a live possibility.
Finally, the water. Arlesey sits close to the confluence of the River Hiz and the River Ivel, and the Environment Agency monitors a River Hiz at Arlesey gauge station directly. Low lying ground near a watercourse drains slowly when the river is up, and a drainage system that copes fine in August can back up in February for reasons that have nothing to do with what is in the pipe.
Who owns which drain, and who you should be ringing
Start with the company, because Arlesey trips people up. This is Bedfordshire, so foul water is Anglian Water’s, not Thames Water’s and not Affinity Water’s. Households who have moved a few miles south from the Hertfordshire villages ring the wrong number every year, and your wastewater bill is the one place that settles it for your address.
Then the line on the ground. In October 2011 the shared runs and the lateral drains that householders used to own were handed to the sewerage undertakers. So the pipe under your own garden, taking your waste and nobody else’s, is still yours to look after. Once that pipe crosses the boundary, or once it picks up the house next door, it has almost certainly stopped being yours. Surface water is the exception that stays put: a soakaway serving your drive or your roof is on your land and remains your problem, whichever way the foul side falls.
A blockage in the public sewer is the undertaker’s to resolve. If the camera puts your defect on their side, we say so and hand you the footage to send them, rather than clearing a public sewer at your expense and keeping quiet about it.
What we do
Blocked drains cleared. Sinks, toilets, gullies, external runs and manholes, by rod, plunger, electro mechanical cutter or jet depending on what is in there.
High pressure water jetting. Cuts through fat, scale, silt and compacted debris and scours the pipe wall properly rather than pushing a hole through the middle of a blockage.
CCTV drain surveys. A camera through the line, recorded, with a written report. Essential before any repair, essential for a home purchase where drainage is suspect, and essential if a blockage keeps recurring in the same place.
Root cutting and removal. Cutting out the root mass, then a camera to find the joint they came in through, because roots grow back to an unrepaired defect.
Drain repairs, patch lining and relining. Cracked and displaced pipe repaired from inside with a resin liner where it can be lined, excavated and replaced where it cannot. On a block paved drive, lining is the difference between a small job and a large one.
Gullies, soakaways and surface water. Gully replacement, channel drainage, soakaway design, and driveway and patio runoff with nowhere to go.
Manhole and chamber work. Replacement covers and frames, rebuilt benching and repaired chambers.
The properties where drainage gets interesting in Arlesey
Church End and the old core north of the station. The historic heart of the village, on the site of the medieval Etonbury complex, with St Peter’s Church and a cluster of listed farmhouses and cottages around it. Older properties here have older drainage, which means salt glazed clay in the ground and often cast iron above it. In shrinkable clay ground with mature trees around, that is the combination that produces root ingress and displaced joints. We camera first on these properties every time, because guessing where a Victorian era drain run goes is a good way to dig a hole in the wrong place.
The southern end of the village, towards the former brickworks and the lagoons. The industrial legacy ground. Where drainage crosses old workings or made ground, settlement is the recurring cause of standing water and slow running drains, and a survey with levels tells you far more than a plunger does.
Fairfield. Arlesey shares this one with Stotfold, and the part that falls to us most often is the housing rather than the converted hospital. Early 2000s plastic drainage laid to modern falls, which means the pipe is rarely the fault. What we attend is what has gone into it, plus the odd chamber lost under a later patio or garden room and a downpipe that somebody has run into the foul side during an extension. Both show up in an hour on camera and neither needs a spade.
Arlesey Cross and the newer estates. The Cala scheme of 146 homes approved by Central Bedfordshire Council in February 2024, which included a new section of the Arlesey Relief Road, along with Arlesey Gate off Stotfold Road and Samuel Gardens at Graves Paddock off Bates Avenue. New drainage, modern materials and generally sound. The issues we attend on new estates are usually construction debris left in a run, or a fall that is marginal, and both show up clearly on camera.
The High Street and the infill plots. The old linear spine, with land to the rear of 214 to 216 High Street identified in the Local Plan for 20 homes and land adjoining Lewis Lane for another 67. Infill development means new connections into existing drainage of unknown condition and unknown route. If you are building, or living next to somebody who is, a pre works CCTV survey is the cheapest insurance available.
The East of Arlesey allocation, around 2,000 homes between the eastern side of the village, the A507 and Fairfield, is the biggest change coming. Building on that scale moves surface water about, so if you are downhill of it, know the condition of your own drainage before it starts.
Fats, wipes and the two things that cause most blockages
The camera tells the same story week after week. Cooking fat poured down a sink cools in the pipe and sets, and then everything else sticks to it. Wet wipes, including the ones marked flushable, do not break down and knit together into a mat. Between them they cause the majority of the blockages we clear in domestic drainage.
Fat goes in a container and then in the bin. Wipes go in the bin, whatever the packet says.
What it costs
We quote before we start. For a straightforward blockage we give you a price on the phone based on what you describe, and if what we find on site is materially different we tell you before we carry on rather than after.
CCTV surveys are priced as a survey and you get the footage and a written report, which is yours to use with an insurer, a solicitor or Anglian Water. Repairs and lining are quoted from the survey, because pricing a repair without seeing the defect is guesswork.
We will not quote a fixed figure for a soakaway or a surface water scheme without knowing the ground conditions, for the reasons set out above.
Trusted & Accredited Professionals
Plumbing and drainage on the same visit
A smell in a downstairs cloakroom or a slow bath is as often a trap, a vent or an internal waste at the wrong fall as it is a blocked run underground. We do the plumbing as well as the drainage, so nobody has to come back with a different van to finish the job.
Drain Unblocking in Arlesey
Kitchen drains are the most common drain unblocking call we take in Arlesey, and the cause is nearly always the same. Fat goes down warm as a liquid and sets hard further along the run where the pipe is cooler. By the time the sink is backing up, the bore can be down to the width of a pencil.
Clearing it is straightforward. Keeping it clear is about what goes down the sink afterwards, and we will say so on the day rather than leaving you to find out when it happens again. Fat and oil into the bin, not the plughole, and a strainer over the waste catches most of the rest.

Frequently Asked Questions
Who is responsible for my drains in Arlesey?
Anglian Water is the sewerage undertaker for this side of the county line, and your bill will confirm it. Since the 2011 transfer, shared runs and the length beyond your boundary are generally theirs to resolve. The run inside your boundary serving only your house is yours, as is any soakaway on your land.
My drain blocks in the same place every few months, why?
Almost always a defect rather than a habit. In ground like this that usually means a displaced or cracked joint in old clay pipework, often with tree roots coming in through it. Rodding it clears the symptom. A camera finds the cause.
Why does my soakaway not work?
Because clay does not soak water away. Regional mapping puts this part of the Ivel valley on Gault Clay, and on clay a conventional soakaway will fill and stay full. The design has to change to suit the ground, which is why an infiltration test comes before a hole gets dug.
Is a drain survey worth it before I buy here?
In the older parts of the village, particularly around Church End and the High Street, it usually is. You get recorded footage and a written report.
Will the block paving have to come up?
In many cases, yes. Patch repairs and full relining are done from inside the pipe using a resin liner. Where the pipe is collapsed rather than cracked, excavation is the only honest answer and we will say so.
Do you come out at night for a blocked drain?
Yes. Sewage backing up into a house is an emergency and we treat it as one, 365 days a year.
