Some converted towers have been spoiled by the addition of stairways and extensions and insertion of windows and planners should be careful if the conversion involves removing the tank (if it is exterior) as that would alter the proportion of the building which the Victorian and Edwardian engineers were very considerate of. In Dereham's case the tank is interior. At Leiston the tank was removed but dummy tank walls were erected to preserve the original profile. Sometimes an exposed tank has been replaced by a glass structures of similar size acting as a rooftop garden or enclosed gazebo.

The tower at East Dereham was built in 1889, from my research, although the date of 1881 is often quoted. I believe the waterworks was built, despite a "Keep Dereham Dry" campaign - as the residents thought the scheme too expensive.
In 1881 East Dereham¹s original borehole was sunk into the chalk underlying Cemetery Road at a cost of £4,000. By 1889 treatment works had been completed together with a square brick water tower into which the treated water was pumped by a steam engine (³Dereham Past and Present², p32). Before this date, water was obtained from wells or pumps. Most properties had their own but there were three public pumps; in the Market Place near the Assembly Rooms, at the junction of London Road and Baxter¹s Row and in Washbridge (³Looking Back at Dereham, p28, 29 see folder ŒDereham¹²). Located in Cemetery Road, O.S. Grid Ref. TF 99112 14218, Capacity 30,000 gallons.
Notes: The tower appears much as it did originally, but no longer has the penthouse on top of the roof as illustrated in the ³Story of EAST DEREHAM², p66. Grade II listed on 22nd June 1984. IoE #219497.
