Water was originally obtained from wells.
The South Cambridgeshire Rural District Council Report 1938 stated:
'(Parishes of Arrington, Abington Pigotts, Bassingbourn, Croydon, East Hatley, Gamlingay, Guilden Morden, Hatley St. George, Kneesworth, Litlington, Little Gransden, Steeple Morden, Shingay and Wendy.) The scheme for the provision of a piped supply of water to these parishes is nearing completion and work is now proceeding in the laying of service connections from the mains to property boundaries. This will continue, according to application, until the end of 1939. During the interim period Bassingbourn Aerodrome has been supplied by temporary pumping arrange¬ ments and the completion of the service reservoir in July enabled a supply to be maintained to a few properties urgently requiring water.'
