Chaveywell Spring and Calne's Water Supply

There are said to be many springs under the slopes of Castlefields, but none as important as the spring known as Chaveywell. As described on the plaque that hangs above the current outlet for the Chaveywell Spring, there was an epidemic in Calne between 1880 and 1890. The water in Calne became polluted and this lead to a number of deaths, probably from Typhoid. This spring was the only spring to remain pure and was relied upon until the new supply from Calstone was available.


Chaveywell, or Clamy Spring, begins in the grounds of St. Mary's School. From the school the spring runs under Curzon Street, Quarr Barton, Marden Court, Castle Street, following a sourtherly direction to exit at Chaveywell (WANHSAFG, 2011)[1]. During the 2010 excavations in search of the Calne Castle, a trench (trench 4) was dug near the exit for the spring and it was found that the original medieval outlet for the spring was 3 metres west of the current outlet. It is assumed that movement or slippage of the ground, or collapse of the tunnel, which could have been caused by tree roots is what has caused the spring to exit at a slightly different point. Upon opening the trench the archeaologists found a well constructed stone arch, which is now bricked in, with the water exiting via a metal pipe. They report that an iron or lead bath used to collect the water, but it is assumed that this was taken for the War effort during WWII.

These days the pure water from the spring flows into a trough which leads to the canal.
The water is wonderfully clear, with the trough being a favoured place of dogs wanting a cool down and a drink!

Back in the 1870s - 1880s, water supply and sanitation in Calne was known to be poor. In nearby Highway, the Calne rural sanitary authority's inspector visited a case of Typhoid and cautioned the residents from using their well, which was contaminated by sewage[2].

A report entitled "Dr. Blaxall's Report to the Local Government Board upon the Sanitary Condition of Calne in connexion (sic) with an Outbreak of Diphtheria and Typhoid Fever in that Town" [3] reported on the water supply and sanitation of Calne. The report, written by George Buchanan in 1884 as an update to his previous report in 1874, states that in the interim period that some 'good work' had been done, little or nothing had been done in other matters, for example with cesspit privies still in general use. Even the water closests that did empty into the sewers (built around 1881) weren't supplied with water for flushing meaning that the waste lodged in the drains - certainly not a Calne we'd imagine living in today.

Where Buchanan was pleased was the water supply where he states: "Here a great improvement has been effected". At this point the town no longer had to rely on local wells, such a Chaveywell due to the reservoir that has been built two years earlier in 1882.

The reservoir was built in Calstone Wellington near the source of the Marden, the river that flows north west up into Calne, then flows westerly to meet the Avon on the east of Chippenham. At Calstone Wellington there are many springs and it provided "a plentiful supply of good water". However, at the point when Buchanan wrote his report, only 100 houses of approximately 732 houses (in the 1881 census as quoted by Buchanan, 1884) were supplied from the new source, which was supplied via gravity and iron pipes. Even though there was a plentiful water supply from Calstone, the rest of the houses were still using local wells that were subject to pollution, in Buchanan's view, "a circumstance of the highest sanitary importance".

Over time all houses were moved to a Calstone supply and sewers were completed. Wells and local springs lost their importance and Chaveywell is the only spring in the area to still have a name (if any others ever did?). Although there was a farm located at Chaveywell until the 1920s, as can be seen in the book Calne Revisited by Peter Treloar. However, with water supply coming from one large source, there was potential for a lot of damage to be done to residents using the supply with one act of terror. The Gazette and Herald, in their "From the Files" articles reprinted a story from around 1914 whereby Calne Water Company had to arrange for the reservoir to be under 24 hour guard as two suspicious invididuals were seen loitering in the vicinity of the reservoir. This lead to rumours spreading that their intention was to poison the water supply [4].


However, this type of situation was rare and today while the Chaveywell Spring is celebrated as saving the lives of Calne inhabitants due to the pure water that flowed from it; the Calstone reservoir is due to by mothballed as the 'good water' is found to be bad.

These days the reservoir is only used at times of high demand and sadly is a risk site for Cryptosporidium, a horrid parasite that can result in diarrhea, fever, nausea, and vomiting. With 42 positive detections found between the June and November of 2013 (the most recent Drinking Water Inspectorate report I could find mentioning Calstone reservoir) [5], Wessex Water's 2017 decision [6] to mothball the site as part of their rationalisation of assets seems to be a sensible one.

So, over 100 years later, the attempts to improve Calne's water supply is ongoing, this can only be a good thing. Especially considering the hundreds of houses currently being constructed adding to the 1,935 households reported in the 2011 census [7], the water requirement of the town is heading swiftly upwards.

Appreciation of the past is evermore important these days, but at the same time moving towards greater efficiency and water safety is - as it always was - "a circumstance of the highest sanitary importance" (Buchanan, 1884).
