Victoria County History Of Wiltshire, Volume 8, page 132:
As with its predecessor, the first problem which faced the council [Warminster Urban District Council formed under the Local Government Act of 1894) was one of sewage disposal. There were still parts of the town not served by the system, including the Furlong and new houses at Imber Road, beside more outlying parts such as Woodcock and Hillwood Lane. At the Common some sewage still ran into the stream. There were also frequent complaints about smells from the sewage farm, and the government urged that the whole system should be reviewed. When this was done it was found that the farm was ill-arranged and too small. After much consideration it was decided to pump the sewage to a more suitable area. Smallbrook Mill was bought for the purpose, and a piece of sloping land north-east of Butler’s Coombe Farm was adopted as the new farm. The work of laying new sewers in areas not previously served was still going on in 1901.
