The first SAASU provinces of South African aquatic sports were Western province and Eastern Province. After the Boer War ended in 1902 they were joined by the newly conquored colonies of the Orange River Colony (ORC), and Transvaal. Mossel Bay and East London had been sending their own teams, although they later became part of Eastern Province and Border. The Transvaal soon split into Northern and Southern Transvaal, with Eastern and Western Transvaal emerging later. The northern Cape city of Kimberley became the home of the Griqualand West province. Rhodesia was always one province, as was South West Africa. The Vaal Triangle emerged in the 1970's.
Rhodesia withdrew from SAASU in 1980, and South West Africa in 1990.
By 1997 SAASu no longer existed and all the existing provincial bodies were replaced by government mandated entities.
Most significantly, the old inter-provincial traditions and rivalries disappeared as the national championships became an inter-club competition. The separate aquatic sports no longer held combined national championships.
With the new national governing body - known as Swimming South Africa - barely acknowledging the history of aquatic sports in South Africa, and failing to maintain historical information, the new "provincial" governing bodies have also mostly neglected to include any aquatic sports history on their websites.
