Everything about drainage here comes back to the Beane and the valley floor
Start with the river. The Walkern Neighbourhood Plan states that the village lies in the floodplain of the River Beane, identifies both surface water and fluvial flood risk, and carries a flood risk policy, Policy 16. The river is a rare chalk stream, running north to south roughly parallel to the High Street, with most housing on the western side of the valley.
Four consequences follow, and they shape every drainage job here.
The whole village drains downhill towards one line. Housing on the western slope sends surface water east to the low ground along the valley floor, the bottom of the High Street and the Church End area where the lane crosses the river by a ford. In heavy rain it is not the gullies at the top of the slope that fail, it is the ones at the bottom, and a low point gully half full of silt will flood a driveway in ten minutes. Five minutes of maintenance, usually thought about too late.
A high winter water table changes how drains behave. With chalk springs in the parish and a floodplain underfoot, groundwater sits high through the wetter months. Cracked drainage lets it in as readily as it lets waste out, which is why a run that copes in August backs up in February with nothing changed indoors. Seasonal trouble is the first thing we look for on a survey.
Soakaways here need real thought. They only work if water gets away beneath them. On the free draining gravel across parts of the parish they are excellent. On clay, or where the winter water table rises to meet them, they fill and stay full and the patio floods anyway. Anyone putting one in without a percolation test and a look at the levels is guessing with your money.
What leaves the property matters more than usual. The Beane is a rare and sensitive chalk stream, which is why misconnections matter here: a downpipe run into a foul drain, or worse a foul connection into a surface water drain, ends up somewhere it should not. We check what is connected to what and tell you if it is wrong.
The conservation area appraisal records the soils as gravel, flint and clay, which is why the ground varies so much over short distances. Two houses a hundred metres apart can need different answers.
Whose drain is it, and which company sits behind it
Two separate questions, and only one of them has a clean answer in this village.
The clean one is where your responsibility ends. Since the October 2011 transfer, a run shared with other properties, along with the stretch of your own drain that continues past the boundary towards the public sewer, belongs to the sewerage undertaker. Inside the boundary, serving your house alone, it is yours, and so is any soakaway on your ground, since surface water disposal on your own land never transferred.
The less clean one is the company name. Walkern sits three miles from Stevenage in a strip of Hertfordshire where the areas of two different sewerage undertakers, Anglian Water and Thames Water, run up against each other. Thames Water is the most likely undertaker here, on a regional wastewater arrangement rather than anything published for this village, and we are not going to dress that up as settled. The wastewater section of your own water bill names your undertaker, and that is the thing to check before you ring anybody.
Blockages in the public sewer are the undertaker’s responsibility to resolve. If the fault turns out to be on their side of the line, we will say so instead of quoting you for it.
Plenty of properties out in the parish are on no public sewer at all. A septic tank or treatment plant is entirely the owner’s. On a parish built round a chalk stream the discharge rule is the one to know: a tank outfalling into the Beane or any other watercourse cannot stay that way, and GOV.UK expects a drainage field, a package treatment plant or a connection to the public foul sewer arranged inside a reasonable timescale, usually about a year.
What we get called out to around the village
Blocked foul drains. Toilets backing up, gullies overflowing, a manhole standing full. We clear it, then find out why, because an unexplained blockage comes back.
CCTV drain surveys. A camera through the run, recorded, with a written report and a plan. What you want before buying here, before an extension, or before anyone quotes a repair.
High pressure jetting. For grease, scale, root fibre and general build up. Jetting is done at a pressure and with a nozzle suited to the pipe, because putting full pressure through a fragile old clay run is how a partial blockage becomes a collapse.
Drain repairs and relining. Patch liners for a single joint or a short damaged section, full relining where a longer run has failed. A liner cures in place inside the old pipe, so no trench, which in a village of narrow lanes and historic surfacing is usually the right call.
Excavated repairs. Where a pipe has collapsed and relining is not viable, we dig, replace and reinstate.
Gullies, manholes and soakaways. Cleaning, rebuilding, new covers, and surface water drainage designed for the ground you actually have.
Why old clay pipework fails here, and what puts it right
The oldest buildings here predate piped drainage. Around forty per cent of the listed buildings in the conservation area are seventeenth century and a further thirty two per cent eighteenth, with the earliest fabric fifteenth. None of them was designed around drainage, so every drain serving them is a later addition, often altered since.
Underground that means salt glazed clay in short lengths with mortar joints, laid shallow, with a bend or two more than it needs and often no record of where it runs. Clay is a good material, and it fails in three predictable ways.
Joint displacement. Seasonal ground movement opens the mortar joints. Waste gets out, groundwater gets in, silt accumulates.
Root ingress. The big one in a village of mature gardens, hedgerows and established trees along the lanes. Roots get in through a gap of a millimetre or two at an open joint and grow into a mass that catches everything passing. A cutting nozzle clears it and it comes back, unless a patch liner seals the entry point.
Collapse. Cracked pipe under a drive laid over it, or a section that has given up after decades of joint movement. A survey finds it before it becomes an emergency.
The Walkern properties that give drainage the most trouble
Froghall Lane and the newer development to its south. Permitted on appeal in February 2016 for up to eighty five dwellings. New drainage, correctly laid, with different problems: surface water attenuation and where the site discharges, adoption boundaries between developer and undertaker, and the usual construction debris left in the runs. A camera finds that quickly on a newish property.
Totts Lane, running past the allotments. Rural lane drainage: shallow runs, older than anyone can remember, and roots from boundary hedging. Silt off unmade ground and soil carried in surface water are constant contributors.
The bottom of the High Street, by the old watermill. The lowest point in the village, right on the water, with the highest groundwater and the heaviest surface water load in the parish. Non-return valves and clean gullies matter far more here than fifty metres up the slope.
Church End and the ford. A lane crossing the Beane at ground level. Surface water has a very short journey to the river here, so it has to get away quickly and whatever it carries goes into a sensitive chalk stream. Work down here is done cleanly or not at all.
Bassus Green and Clay End. Outlying hamlets, older cottages, farm structures and long runs, usually with no record of the layout anywhere. The first person to find out where those pipes go should be us with a camera rather than you with a digger.
Fats, wipes and the things that block drains
Most blockages we clear in the village are caused inside the house.
Wipes are the worst, flushable ones included, because they do not break down and mass up at the first restriction. Cooking fat is second, down the sink warm and set on the pipe wall cold. Sanitary products third.
Nothing but the three Ps should go down a toilet, and fat belongs in a jar and then the bin. That single habit prevents most of what we get called to.

What it costs
A straightforward blockage clearance is charged at a call out rate, quoted before we set off, with an out of hours rate applying at night and weekends. You will know the figure on the phone.
A CCTV survey with a written report is a fixed price. Repairs are quoted after it, because pricing a drain repair without seeing inside the pipe is not something an honest firm does. A patch liner sits at the lower end, a full reline above it, and an excavated repair with reinstatement higher again depending on what is over the pipe.
If a survey shows the problem is on a shared drain or a lateral beyond your boundary, we will tell you it is the undertaker’s to resolve rather than invoicing you for it.

Frequently Asked Questions
My drain only backs up in winter. Why?
Usually groundwater getting into cracked or open jointed pipework. The village sits in the Beane floodplain with a high winter water table, so infiltration is a common finding and a survey confirms it.
Is the blocked drain outside my boundary my problem?
Generally not. Since the October 2011 transfer, shared drains and laterals beyond the boundary sit with the sewerage undertaker, and clearing the public sewer is their responsibility. Thames Water is the most likely undertaker for this village, though the only place it is confirmed for your address is your own water bill. We will tell you which side of the line your blockage falls on.
Can you fix a broken drain without digging up the garden?
Very often, yes. A patch liner repairs a single defective joint and a full liner renews a longer run, both from inside the pipe. In a village with mature gardens and historic surfacing that is usually the better outcome.
Will a soakaway solve my flooded patio?
Only if the ground takes water. The soils across the parish are gravel, flint and clay, and a soakaway in clay, or one meeting a high winter water table, simply fills. We test first.
Why do roots keep getting into my drain?
Because there is an open joint for them to enter through. Cutting them out clears the drain but does not stop it happening again. Sealing the joint with a liner does.
Do you attend at night?
Yes. Drainage emergencies do not keep office hours and neither does our emergency line.
