Provincial Associations of South African Aquatic sports

The Eastern Province Amateur Swimming Association (EPASA) and the Western Province Amateur Swimming Association (WPASA) were the founder members of the South African Amateur Swimming Union (SAASU).

After the Boer War ended in 1902, the Orange Free State and Transvaal became British colonies, and they duly joined the SAASU. Mossel Bay, Kimberley, and East London joined as regional Centres, that were later absorbed into their respective provinces of Eastern Provinces, Border, and Griqualand West. 

Natal joined in 1905, and Rhodesia became a sporting province in 1920. The Transvaal was split into Southern and Northern Transvaal, and Eastern Transvaal became a separate entity in 1955. The Western Transvaal and South West Africa followed later. 

After the SAASU and the provinces were disbanded in 1995, the new governing body renamed the provinces.
