A former flood plain, springs in the village, and what that means for your drains

Sawston sits low on the River Cam, about seven miles south of Cambridge, and the village’s own history says it plainly: the low lying ground is a former flood plain that still tends towards the moist, and it took dredging of the local ditches and rivers to ease the general flooding problem. There are springs in the grounds of Sawston Hall in the middle of the village. This is wet ground, and wet ground changes how drainage behaves.

Groundwater gets into old drains as easily as sewage gets out. With a high water table, a cracked joint in an old clay run lets clean groundwater seep in, filling the pipe with flow it was never sized for. The system then copes in a dry August and backs up in a wet January, and the homeowner thinks the drain blocks at random. It is infiltrating, and the only way to see it is with a camera.

Soakaways need testing here, not assuming. On ground that tends towards the moist, a soakaway can fill from below and do nothing at all. Before we install or recommend one, we do a percolation test. Anyone who quotes you a soakaway in Sawston without one is guessing with your money.

Surface water matters as much as foul. In a village kept dry by ditches and dredged watercourses, blocked gullies, silted channel drains and neglected land drains show up fast. Keeping the surface water side moving is part of why the village stays dry.

Mature trees and old clay pipework are a bad combination. Under the historic core along the High Street, and around the Hall grounds with their mature trees, there is old clay drainage with rigid joints. Roots find the moisture at a joint, grow in, and the blockage returns to the same spot every year or two until the defect is repaired.

Who is actually responsible for your drain in Sawston

Sawston catches people out here, because two different companies are involved and neither is the one most of Cambridgeshire expects.

Your clean water comes from Cambridge Water. Your wastewater and sewerage service is Anglian Water. They are separate companies, and ringing the wrong one wastes a morning. For anything to do with drains and sewers, the sewerage undertaker is Anglian Water, and your wastewater bill will confirm it.

Then there is the line on the ground, which moved in 2011. Since the transfer of private sewers and lateral drains, the section of your drain beyond your property boundary, and any run that serves more than one property, belongs to the sewerage undertaker. What remains yours is the private drainage inside your boundary that serves your house alone, plus the surface water side on your own land, because soakaways and driveway drains were never part of the transfer.

In practice: a blockage between your kitchen gully and your boundary is yours to fix. A blockage in a shared run behind a terrace, or out in the lateral under the pavement, sits in the public sewer, and resolving that is Anglian Water’s responsibility. Before you spend anything with us, we’ll tell you honestly which side of the line your problem falls on.

What we do

Blocked drain clearance. Rods, electro mechanical machines and high pressure jetting, chosen to suit the blockage and the pipe rather than whatever happens to be nearest the van door.

High pressure water jetting. The right way to shift fat, silt, scale and root fibre. Jetting scours the pipe wall clean instead of punching a hole through the middle of the obstruction and leaving the rest to re-block.

CCTV drain surveys. A recorded camera survey with a written report. The essential first step where a drain blocks repeatedly, before a repair is priced, and before you buy a house with older drainage under it.

Root cutting and removal. Cutting heads on the jetting unit to clear the root mass, then a survey to find the defect the roots came in through, because they always return through the same joint if it is left open.

Drain repairs and relining. A patch liner for a single failed joint, full length cured in place lining for a run with multiple defects, and excavation only where a pipe has genuinely collapsed and lining is no longer an option.

Gullies, manholes and inspection chambers. Cleared, rebuilt where needed, broken or dangerous covers replaced.

Surface water drainage. Channel drains, driveway and patio drainage, land drain advice and soakaways sized for the ground they are actually going into, with a percolation test first.

Why Sawston drains block

Fat, oil and grease. Fat goes down the sink warm, cools inside the pipe, and sets solid. Years of it narrow the bore until a Sunday roast finishes the job. Slow, shallow runs in older properties suffer first.

Wipes. Nothing marketed as flushable behaves like it. Wipes snag on the first rough joint or root and everything behind them builds up.

Root ingress. The single most common cause of repeat blockages in the older parts of the village, for the reasons above: mature trees, old clay joints and reliably moist ground.

Cracked and displaced clay pipework. Old salt glazed clay was laid in short lengths with rigid joints. Ground movement and a century of loading open the joints, and on a high water table the defects both leak and infiltrate.

Silt. Fine material washes in at defects and settles along the invert, quietly reducing capacity until the drain blocks for no visible reason. Common in surface water runs here.

Building over and bad alterations. Extensions that buried a manhole or added a blind bend, and misconnections putting foul water into a surface water drain. A camera finds these in an hour.

The properties where the job gets more interesting

The High Street and the historic core. Sawston’s conservation area is centred on the High Street spine, where the listed stock includes houses, five pubs and buildings going back centuries. Drainage under fabric like this has been altered repeatedly over generations, gradients are shallow, access is tight, and nobody has a reliable plan of what is down there. These runs get surveyed, not rodded on hope, and any excavation near listed fabric gets planned carefully.

The old industrial sites. Sawston was a working village with a paper mill on the Spicers site at the north west corner of the parish and two tanneries, one bordering the Hall grounds and one on the Pampisford boundary. Buildings like the listed former engine house and crust warehouse, and conversions around them, carry long, old and unusual drain runs that were laid for industry rather than housing. A CCTV survey is the only sensible starting point on that stock.

The post war estates to the north west and south. The bulk of the village’s housing went up after the war, and it is where most of our drainage work comes from. Fifties and sixties runs are clay and reaching the age where joints open; more recent plastic drainage is usually sound, so blockages there are nearly always usage related rather than structural. We tell you which, because the fixes cost very different money.

The southern edge towards Pampisford and Unity Campus. Development has effectively merged Sawston into Pampisford, and the newest housing sits on this side. Modern drainage, but new estates bring their own issues: builders’ debris left in runs, driveway drains installed to a price, and surface water systems that need the silt cleaned out before they fail.

The surrounding villages. Some outlying properties are on private drainage, with septic tanks or treatment plants rather than the public sewer. Different rules, different maintenance, different failures. We survey and advise on those too.

Buying a house in Sawston

A homebuyer survey does not look inside the drains. In a village with old clay runs under the historic core, moist ground and a high water table, that is a genuine gap. A pre purchase CCTV survey tells you whether the run is sound, whether roots are already in the joints, and whether anything has been built over, all before you exchange rather than after.

Drainage and plumbing from one firm

A gurgling WC, a slow basin and a smell in the hallway can be a blocked drain outside or a trap, waste or soil stack problem inside. We are plumbers as well as drainage engineers, so whichever it turns out to be, the same team deals with it. If the visit uncovers a hidden water leak rather than a drain fault, our leak detection in Sawston service picks it up, and for anything else in the house there is general plumbing in Sawston.

What it costs

A straightforward clearance is priced as a callout and a first hour, with anything beyond that agreed before we continue, and we give you the rate on the phone before we set off, out of hours included.

Pricing for surveys, jetting and repairs depends on the run’s length, depth and condition. A patch liner on one joint is a few hours’ work; excavating a collapsed pipe under a drive is a different job entirely. We do not put a number on a repair until the camera has been down, because any figure produced before that is invented.

Frequently asked questions

Who do I call first, you or Anglian Water? If the blockage is beyond your boundary, or in a run shared with a neighbour, it sits in the public sewer and resolving it is Anglian Water’s responsibility. If it is inside your boundary and serves only your property, it is yours. Ring us on 01462 506374 and we will help you work out which it is before anybody spends money. And note it is Anglian Water for sewerage even though Cambridge Water supplies your tap water.

Every year, my drain blocks at exactly the same spot. Why? Because there is a defect there: an open joint, root ingress, a buried manhole or a bend added during an extension. Rodding clears the symptom and leaves the cause. A CCTV survey finds it, and in Sawston’s older clay runs the cause is usually roots or a displaced joint on this moist ground.

Can groundwater really get into my drains in Sawston? Yes, and here it is a live issue. The village sits on a former flood plain that still tends towards the moist, with springs in the Hall grounds, so the water table is high. A cracked drain lets groundwater in, which shows as a system that copes in dry weather and backs up whenever it rains.

Will a soakaway work at my property? Not without checking. On low lying, moist ground a soakaway can sit in the water table and never empty. We carry out a percolation test before recommending one, and if the ground will not take it we say so and look at the alternatives.

Do you have to dig up the garden to repair a drain? Usually not. A patch liner or full length liner fixes most defects from inside the pipe, without any excavation. We only dig where a pipe has actually collapsed, and the camera tells us that before we quote.

Is a pre purchase drain survey worth it in Sawston? On anything in or near the historic core, or any house with mature trees nearby, yes. Old clay drainage on a high water table is exactly the combination that hides expensive defects, and recorded footage before exchange is cheap by comparison.
