The watercourse called Hobson’s Brook and Hobson's Conduit flows through Trumpington to Cambridge, from Nine Wells into the city. This page is an introduction to the Brook and Conduit. See Hobson’s Conduit: the First 400 Years for details about the history and route of the Conduit.

Extract from title page of Bushell's 1938 book about Hobson's Conduit.

The Vicar’s Brook originally flowed from its spring-line source at Nine Wells, in the parish of Great Shelford, through Trumpington and then into the River Cam at its present-day outflow near River Farm. In the early 17th century, the University and town of Cambridge diverted this stream near ‘Trumpington Ford’ (where the London Road crossed the brook) with a newly created drain that ran, and still runs, into Cambridge. The watercourse is now named Hobson's Brook from Nine Wells to the point where it divides into the stream, still called Vicar's Brook, and the artificial channel, called Hobson's Conduit.

The original purpose of this ‘new river’ was to flush out the ancient Kings Ditch that had, over the centuries, become a significant health risk. Once the water was flowing into Cambridge though, it was used for other purposes: a fountain on Market Hill, feeding ponds and swimming baths in Pembroke, Emmanuel and Christ’s Colleges, and the pond in the University Botanic Garden, originally on its old site north of Pembroke Street, and latterly on its modern site alongside the brook.

The original 'Hobson’s Conduit' fountain was removed from Cambridge market in 1849, and rebuilt in its present position on the corner of Lensfield Road and Trumpington Road.

The Brook and Conduit are named after Thomas Hobson, the well known (and wealthy) carrier of Cambridge, also known today for the phrase Hobson’s choice. He was probably at least partly instrumental in bringing the water to Market Hill, and certainly left land in his will (in 1631) for the benefit of maintaining the watercourse.
