The water in Sawston, and what it does to your plumbing
Sawston sits on chalk, and the water shows it. Your mains supply comes from Cambridge Water, and the Cambridge Rural supply zone that covers Sawston parish is published at 317.9 mg/l as calcium carbonate, which is 22.3 Clark degrees. Cambridge Water states plainly that it supplies hard water across its entire area. Sawston is at the hard end even of that.
Something worth knowing that catches a lot of people out. Your clean water and your dirty water are handled by two different companies here. Cambridge Water supplies the mains. Anglian Water is the sewerage undertaker, and Sawston’s foul drainage runs to Sawston Water Recycling Centre. Cambridge Water bills the sewerage charge on Anglian Water’s behalf, so you get one bill and most people never realise there are two companies involved. It matters the moment something goes wrong outside your boundary, because it decides who you ring.
What 318 mg/l actually does to a house: scale on immersion heaters and cylinder coils, scale inside combi plate heat exchangers, seized shower valves and cartridges, furred tap aerators, and washing machines and dishwashers that fail earlier than they should. On mixer showers it usually shows up as a drop in flow on the hot side only, because the hot passage scales first. We carry scale reducing fittings as standard here rather than ordering them in, and on any cylinder or boiler work in Sawston we will talk to you about scale protection, because in this water it is not an upsell, it is what protects the warranty.
What plumbing work in Sawston actually involves
Most of what we do here is everyday. Burst and leaking pipes, tap and valve replacement, stopcocks that will not turn or will not seal, toilet and cistern repairs, radiator and thermostatic valve work, outside taps, washing machine and dishwasher plumbing, hot water cylinder work and mains pressure complaints.
Burst pipes spike in winter and they nearly always happen in the same three places: loft runs above the insulation, unheated garages and outbuildings, and pipework on external walls that was never properly lagged. If you take one thing from this page, know where your stopcock is before you need it. In the Victorian terraces along New Road and South Terrace it is often under the kitchen sink or in a floor recess by the front door. In the 1950s and 1960s estate housing it is more often in the kitchen or the airing cupboard. On the new Babraham Road developments there will usually be an internal isolation valve close to where the supply enters, plus an external stop tap at the boundary. We will show you yours on any visit, it takes two minutes and it can be the difference between a wet floor and a wrecked ceiling.
Mains pressure is the other regular one, and in the older parts of the village it is usually a supply pipe sized for a single bathroom now feeding a house with two, plus a utility room. That is a genuine diagnosis rather than a sales line, and where it is the answer we will say so instead of fitting a pump onto a problem a pump will not fix.
Our emergency line is answered by a person, at any hour, 365 days a year. On a burst the priority is always the same. Get the water stopped, then fix the actual fault properly rather than patch it and leave.
The properties where the job gets more interesting
Sawston’s housing is unusually easy to read, because industrialists built most of it and they dated their work.
The historic core. The village runs as a long line along the High Street, with Church Lane, Mill Lane and Common Lane running east to west towards what were once fords on the river. Long narrow plots run back from the road. Building materials in the core include timber frame, gault and soft red brick, clunch, flint and thatch. Rendered clunch and lath are what you are cutting into when you chase a pipe here, and it does not behave like brick. Access is the real constraint: these plots have limited rear access and the High Street is the only through route in the centre, so a van outside for a day needs planning rather than assuming.
The tannery and paper mill terraces, 1853 to 1882. This is the layer that defines Sawston. The Spike was built from 1853 as housing for workers at Thomas Sutton Evans’s tannery, and Evans put up South Terrace and housing along the main road in the same year. The papermaker Edward Towgood built five rows of brick terraces in New Road in 1878. Crampton Terrace, north of Mill Lane, went up in 1882 and is the one with the decorative pargetting. Around forty or fifty villas and cottages followed in the few years before 1883.
Practically, this is solid wall construction with original service runs, shared rear alleys and drainage that was laid to serve a row rather than a house. Expect lead or old iron on the incoming supply until proven otherwise, expect a stopcock in an awkward position, and expect the waste from next door to be sharing your run. That last point has a legal consequence and we deal with it further down this page.
Church Field and the post-war estates. Sawston’s first council houses went up in 1921 and there were over 750 by 1972. Building on the Church Field estate ran right through the 1950s, with about forty of the fifty-five available acres built over by 1963 and more following by 1969. The 1960s brought estates north of Babraham Road, between New Road and Mill Lane, along Common Lane and west of the main road, including the Deal Grove development of houses and bungalows. The bypass opened in 1968.
This is the bulk of Sawston’s stock and the census bears it out: 47.7% of households here are semi-detached. It is also where we find the most microbore, the most original 1970s pipework still in service, and the highest concentration of cylinders that have quietly been scaling for forty years.
The new Babraham Road developments. A 158 unit scheme including sixty-three affordable council homes, followed by 280 homes approved in April 2022, marketed by Redrow as Tudor Meadow. Modern plastic and copper throughout, sealed systems, manifolds and few surprises, but with the same 318 mg/l water arriving at the stopcock as everywhere else in the village. New pipework does not stop limescale, it just delays the day you notice it.
Two different grounds under one village
Sawston straddles two genuinely different ground conditions, and it explains a lot of what we find.
The valley floor along the western edge, taking in Mill Lane and the old mill, is alluvium and river terrace gravel. The British Geological Survey describes this material as very soft to firm clay and silt with loose to dense sand, high moisture content, compressible and prone to uneven settlement, with peat present in places. Shallow groundwater is normal here. That combination is why underground drain runs on this side of the village move, why joints open at the wrong angle, and why a leak on a buried supply pipe can travel a long way before it appears anywhere you would look for it.
The higher ground to the east, where the village college and the post-war estates sit, is chalk with Lowestoft Formation till over it, an overconsolidated sandy clay carrying chalk and flint. It drains freely, which is good, but the clay component shrinks and swells with the seasons and the Survey identifies vegetation, and trees especially, as the dominant control on that movement. The chalk beneath is also prone to dissolution features.
One constraint that is genuinely local and worth stating plainly: Sawston sits over designated groundwater Source Protection Zones. That restricts what may be discharged to ground. If anybody proposes dealing with descaling waste or a condensate run by putting it into a soakaway here, that is the wrong answer.
On flooding, the honest position is that the built-up village is mostly in Flood Zone 1, which is low risk from rivers. But Sawston is named as a South Cambridgeshire priority wetspot for surface water in the county’s Surface Water Management Plan, and low points do pond. River flooding is not the issue here. Water with nowhere to go in a downpour is.
While we are on the subject, the watercourse along Sawston’s western boundary is the River Cam, shown on older mapping as the Cam or Granta. The River Granta is a separate chalk stream that comes down from Bartlow through Linton, the Abingtons and Babraham and joins the Cam at Stapleford, just north of the village. Plenty of trade websites get that the wrong way round.
Who is responsible for which pipe
This one saves people money, and it matters more in Sawston than in most places because of those Victorian terraces.
On 1 October 2011, all privately owned sewers and lateral drains connecting to an existing public sewer transferred to the sewerage undertaker. In Sawston that undertaker is Anglian Water. A sewer, for this purpose, is a drain shared by more than one property. A lateral drain serves one property but runs beyond its boundary. Both became Anglian Water’s responsibility. A drain serving a single property and staying within its own boundary stayed with the owner.
So on Crampton Terrace, South Terrace, New Road or Springfield Road, where a rear drainage run typically serves a whole row, that shared run is very likely Anglian Water’s to maintain, not yours. We will tell you when a blockage sits on their side rather than quoting you for work you should not be paying for.
For completeness: Cambridgeshire County Council handles roads and their drainage, and is the Lead Local Flood Authority for surface water, ordinary watercourses and groundwater. The Environment Agency is responsible for main rivers, which includes the Cam.
The conservation area, and what it means on site
Sawston Conservation Area was designated on 26 March 1974 and the current appraisal was adopted on 15 June 2023. It covers the historic core around the High Street and Church Street, taking in Church Lane, Mill Lane, Common Lane, Shingay Lane, Camping Close, Catley’s Walk, Portobello Lane, Tannery Road and Burnands Place, the parish church and the grounds of Sawston Hall. It contains over thirty listed buildings, and the parish as a whole has forty-six, of which Sawston Hall and the Parish Church of St Mary are Grade I.
The practical point for our work is flue and plant siting. In a designated area a flue must not be fitted on the principal or side elevation fronting a highway. On the High Street terraces, which front directly onto the road, that usually means a rear or side termination or a room sealed vertical flue rather than the obvious position. On a listed building, permitted development rights fall away and listed building consent is needed in addition to planning permission. Outdoor units for air conditioning are treated differently from heat pumps under the planning rules and normally need permission, so we check with South Cambridgeshire before quoting rather than fitting first and finding out after.
What it costs
General plumbing is quoted before we start, not after, because the range of work is too wide for a list price to be honest. That applies to a tap washer and a cylinder replacement alike. Emergency call-outs are quoted up front too, so there is no surprise number once the job is done.
The one exception is a straightforward boiler swap, which we quote from a fixed £2,850 including installation, flush, warranty registration and VAT. A conversion or a back boiler removal is priced separately once we have seen the property. Finance is available on larger jobs.
Sawston is around 27 miles from our Stevenage base, roughly half an hour out along the A505 and down the A1301, and we work across South Cambridgeshire regularly. A job here is scheduled like any other, not squeezed in as an outlying booking.

Frequently asked questions
How hard is the water in Sawston?
Very hard. Cambridge Water publishes the Cambridge Rural supply zone that covers Sawston parish at 317.9 mg/l as calcium carbonate, which is 22.3 Clark degrees. Every zone Cambridge Water supplies is classed as hard to very hard. It is worth planning for on cylinders, combis, showers and appliances rather than treating it as an afterthought.
Who do I ring about a blocked drain in Sawston?
It depends where the blockage is. If it is inside your boundary and serves only your house, it is yours. If it is shared with a neighbour or runs beyond your boundary, it almost certainly transferred to Anglian Water in October 2011 and is their responsibility. We will tell you which it is before quoting. If it is on the highway, that is Cambridgeshire County Council.
Do you cover Sawston at night and weekends?
Yes. The emergency line runs 24 hours a day, 365 days a year, and it is answered by a person rather than a message service. Our office and admin hours are ordinary working hours, so a quote request sent at 2am is read in the morning, but a burst pipe at 2am gets a phone answered.
My house is on the High Street and it is listed. Can you still work on it?
Yes, and it is a normal part of what we do in South Cambridgeshire. The difference is that we check the constraints before quoting rather than after. On a listed building, permitted development rights for things like flues and outdoor units do not apply and listed building consent is needed alongside planning permission. Getting that sequence right is what stops a job going wrong.
I have low water pressure. Will a pump fix it?
Sometimes, but often not, and in the older parts of Sawston it usually is not the right answer. The common cause here is an undersized or partially blocked incoming supply pipe feeding a house that has gained a second bathroom since it was built. A pump on the wrong side of that problem makes it worse. We check the incoming supply first.
Do you work on oil heating?
The census records 128 Sawston households on oil only, about 3.9%, so it is a real if small part of the village, mainly on the outer edges. Tell us what you have when you call and we will be straight with you about whether it is a job for us.
