SK5979 : Bracebridge sewage pumping station
taken 9 years ago, near to Worksop, Nottinghamshire, England
Built in 1881 it housed a pair of steam powered beam engines to pump sewage to the sewage farm. These were replaced by electric pumps after the Second World War, although much of the supporting framework in cast iron survives, displaying Gothic detailing.The station ceased to be used after the construction of a new sewage treatment plant at Kilton, and fell into some disrepair, as can be seen in David Stowell's 1994 view. Since then remedial work has been carried out, at least making the roof watertight, and blocking doorways to prevent access by vandals.
The building is Listed Grade II.
Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.
In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.
There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.
In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.
In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
