There are two sites in Sawston which support or have formerly supported Tanning facilities. The site south of the village centre and backing onto the grounds of the Sawston manor house – Sawston Hall – is the Hutchins and Harding site. The other site is on the southern border of the village, crossing over into neighbouring Pampisford, the Eastern Counties Leather site which has now been mostly converted into a general industrial estate. These industries were introduced into Sawston to take advantage of the clean water supply. Examination reveals that both sites are located on bore holes or streams.
