Two rivers, a dead canal, and what that means for your drains
Shefford is built at a meeting of watercourses. The River Flit and the River Hit come together close to Northbridge Street, and the combined channel became the Ivel Navigation, which was extended to Shefford in 1823 and closed in 1876, running on into the Ivel system that joins the Great Ouse at Tempsford. The town’s two bridge streets are named for the crossings.
For drainage this matters in three concrete ways, and none of them are theoretical.
Levels. Ground close to two river channels sits low, and drainage relies entirely on fall. Long shallow runs silt up faster, hold solids for longer and block sooner than a steep run on higher ground. On a low lying property we survey the gradient as closely as the damage.
Surcharging. When the watercourses are high and the ground is saturated, anything discharging to a surface water outfall backs up instead. That is when a gully that has coped for years suddenly does not, and when a downstairs toilet runs slow for two days after heavy rain and then recovers. We look at the rainfall as part of diagnosing that pattern.
We will not tell you what flood zone your house sits in. That designation is published by the authorities, it is worth checking properly before you spend money, and we are drainage engineers rather than flood risk consultants. What we will do is tell you honestly whether your problem is a defect in your pipework or a levels and capacity problem, because the fix for one is nothing like the fix for the other.
Made ground. A canal that closed in 1876 and a railway that shut to passengers in 1961 and to freight in 1964 have both left ground that has been dug, filled and rebuilt on. The former goods yard at the southern end of town is an industrial estate now. Made ground settles unevenly over decades, and uneven settlement is one of the classic causes of a displaced joint or a dropped section in a clay drain.
Who is responsible for which drain
Shefford is in Central Bedfordshire, so the undertaker is Anglian Water, handling water supply and sewerage together. Not Thames Water, and not Affinity Water, whichever of those a neighbour a few miles into Hertfordshire deals with.
Where responsibility sits changed in 2011, when private sewers and lateral drains went across to the undertakers. Plainly: the drain serving only your property, as far as the boundary, is normally yours, and so is any soakaway on your ground, because surface water disposal on your own plot was never part of that transfer. Once the pipe picks up another property, or crosses the boundary towards the public sewer, it is normally Anglian Water’s, and a blockage in the public sewer is theirs to resolve. Manholes in a shared rear access serving several houses usually sit on their side too.
Establish that before anybody starts work, because it decides who pays. Where a survey puts the defect beyond your boundary or on a shared run, we tell you it is theirs and you report it, rather than paying us to fix their pipe.
The historic core complicates it. The street plan through the middle of town has been essentially unchanged since 1736, and drainage there was added in stages over a very long period. Shared runs, drains crossing under neighbouring buildings and connections nobody has a record of are all normal, which is exactly what a camera is for.
The properties where drainage gets awkward
The High Street. Continuous frontages with very few gaps, mostly two storey with some three on the south side, timber frame and brick under clay tile and slate. The consequence is simple and expensive: often no side access at all, so rear drainage is reached through the building or a neighbour’s yard. We plan that before booking the job and bring the right length of hose. Several are Grade II listed, including Tudor House at 36 to 38, and excavation affecting the fabric may need Central Bedfordshire Council involved first.
Northbridge Street and Southbridge Street. The oldest properties, at the two river crossings, with listed buildings among them. Drainage here is old, shallow and often clay. Clay pipe is perfectly serviceable when it is intact and well bedded, and a liability when it is not, because the joints are the weak point and clay is where roots get in.
Ampthill Road and Duck Lane. Part of the historic street pattern and inside the conservation area. Mature trees and long established gardens along these older plots, and roots follow water. A root that finds a weeping joint will fill a pipe with fibrous growth in a couple of seasons. Cutting it out restores flow, but if the joint is not repaired or lined the roots come back, which is why we always want a camera in the pipe after jetting rather than just before.
The former St Francis’ Boys’ Home flats. Institutional buildings converted to residential, with drainage designed for a very different use and occupancy. Shared stacks and shared runs, so a blockage hits several households at once, and working out whose run it is takes a survey and sometimes the managing agent.
Ivel Road and the streets by the old goods yard. Later twentieth century housing, and the point where domestic drainage sits close to the industrial estate. Standard construction, generally accessible, and usually straightforward to survey and jet.
Lucas Gardens and the newer housing east of Ivel Road. The Redrow scheme of 90 homes launched in 2020 and the Line Field allocation of 72. Modern plastic drainage, proper chambers, designed falls and sustainable drainage rather than a simple soakaway. Blockages here are almost never structural: wipes, fat, or construction debris quietly narrowing a run until something catches on it.
What blocks drains, in order of how often we see it
Wipes. The single biggest cause. It does not matter what the packet says, they do not break down like paper. In a shared run serving several properties, it takes one household to block the drain for everybody.
Fat, oil and grease. Poured down a sink warm, solidifies cold, and builds up on the pipe wall until the bore is a fraction of what it should be. Shefford has a working High Street with food businesses on it, and commercial kitchens are a different scale of the same problem. Grease trap maintenance is far cheaper than an emergency jetting call in the middle of a trading day.
Roots. Almost always in older clay pipework with open or displaced joints, and almost always in the older parts of town where trees have had decades to find the pipe.
Collapsed or displaced pipework. Clay drains in Victorian and earlier stock, often laid shallow, often disturbed by later building work, settlement or made ground. This is what a camera confirms and what guessing gets wrong.
Silt and surface debris. Gullies that have not been cleared, and yard drains taking leaf litter and grit into the system.
Surface water overload. Patios, extensions and driveways that were laid without adequate provision, sending more water into a system that was never sized for it. If your gully floods every time it rains hard, and it did not used to, look at what has been paved since.
What we do
Clearing a blockage. Rods for simple work, high pressure water jetting for anything substantial. Jetting cleans the full bore of the pipe rather than punching a hole through the middle of a fat deposit, which is why a properly jetted drain stays clear far longer than a rodded one.
CCTV drain surveys. A camera through the run, recorded, with a written report. This is what tells you whether you have a blockage or a defect, exactly where it is, how deep, and whose side of the boundary it is on. It is also what a solicitor or an insurer will want if a drainage problem shows up on a pre purchase survey, which happens frequently on the older properties around the conservation area.
Root cutting. Mechanical cutting and jetting to clear ingress, followed by a survey to find the entry point, because clearing roots without dealing with the joint is a job you will pay for again.
Repairs and relining. Patch lining or a full liner cures a new pipe inside a cracked or root damaged one with no excavation. On a High Street property with no side access, or under a drive or conservatory, that is the difference between a manageable job and a very disruptive one. A genuine collapse still has to be dug.
Gullies, manholes and soakaways. Clearing and rebuilding gullies, replacing broken chamber covers, and dealing with soakaways that have silted up or were never adequate. On low lying ground a soakaway that worked when it was installed can become useless once the surrounding ground is regularly saturated, and that is a design conversation rather than a cleaning one.
What it costs
We price a drain clearance job on what it is: how the drain is accessed, what equipment is needed and how long it will take. You get the figure before we start.
CCTV surveys are quoted as a defined piece of work with a written report included. Repairs and lining are quoted after the survey, because pricing a repair before you have seen the pipe is guesswork.
If the survey shows the defect is Anglian Water’s responsibility, we tell you and you pay us for the survey, not for a repair you should not be funding.

Plumbing and drainage together
Slow wastes, a gurgle in a WC and a smell in a utility room can be a blocked run outside or a trap, vent or stack fault inside. We do both, so one visit settles which and puts it right.

Frequently Asked Questions
Who is responsible for the drain outside my Shefford house?
Anglian Water is the sewerage undertaker here. Since the 2011 transfer, most shared drains and lateral drains beyond your boundary are theirs. The run serving only your property up to the boundary is normally yours.
Why does my drain back up only after heavy rain?
Usually a levels or capacity issue rather than a blockage, particularly on lower ground near the Flit and the Hit. A survey during and after rainfall tells us far more than one on a dry day.
Do you do CCTV surveys for a house purchase?
Yes, with a written report and footage. It is a common request on the older properties in and around the conservation area.
Does a repair mean losing the garden or the yard surface?
In most cases no. Patch lining and full relining cure a new pipe inside the existing one, worked through the access you already have. A fully collapsed section still has to be dug, and we say so plainly.
Are roots a common problem in Shefford?
In the older clay drainage around Ampthill Road, Duck Lane and the historic core, yes. Mature trees and jointed clay pipe are a reliable combination.
Do you cover commercial drainage on the High Street?
Yes, including grease related blockages in food premises, and we can work outside trading hours.
