Ponds Forge International Sports Centre

Ponds Forge International Sports Centre is a leisure complex in Sheffield, England that contains an Olympic-sized swimming pool with seating for 2,600 spectators, family and children's pools, water slides and other sports facilities.

Ponds Forge was designed by the architects FaulknerBrowns and opened in 1991 as a venue for the 1991 Summer Universiade, which the city hosted that year. In the 1994 UK Sports Design Awards Ponds Forge was highly commended in the overall category, and for the use of steel in its construction it won the British Steel Award. The name Ponds Forge is borrowed from the steel works that formerly occupied this site and a 7 feet (2.1 m) high anvil has been left in situ next to the building, partly because it would have been too expensive to move it. The River Sheaf runs under the site and flooded the car park on 21 December 1991, shutting the complex for 6 days. Proof of this can be found on platform Five of Sheffield railway station, because the Sheaf also runs under that, and it also flooded at the same time. A piece of debris from "The Flood" is displayed there and the plaque mounted on it has the same date. In the 2000s Ponds Forge was a venue (along with the nearby Don Valley Stadium) for Channel Four's 'The Games', in which celebrities competed against each other in a wide range of events.

The 50 metre pool at Ponds Forge is one of ten in the United Kingdom built to current FINA standards, and hence is home to many sporting events. The main pool hall is 90 m long by 60 m wide and when the arches for the roof were constructed temporary supports for them were necessary. When these were removed it "settled" 150 mm. It has two movable bulkheads (so the main tank can be split into 2 or 3 individual pools) and the floors at the end quarters can be raised or lowered from surface level down to 2 m depth. In its long course mode with the bulkheads at the extreme ends it has 10 lanes. If used "width ways" up to twenty 25 m lanes are available. A sophisticated ozone water treatment system is employed that results in lower levels of irritants and reduced toxicity compared with traditional methods of treatment. The quality of the pool means that a great many events are held there which creates valuable exposure for the city of Sheffield and brings in much revenue for the city's hotels etc. The down side is the consequent unavailability for its regular users whilst those events are being held. A number of world records have been set in the pool although only one was long course. The latter was in the heats of the European Championships on the 3 August 1993 when Károly Güttler of Hungary went 1.00.95 to set a new world mark in the 100 m breaststroke. As well as competition-level swimming, the pool is also used for lessons, diving, kayaking and scuba diving. It is also open to the general public for lane swimming.
