Welsh Association of Sub Aqua Clubs
The Welsh Association of Sub Aqua Clubs () (WASAC) was the national governing body (NGB) for "Sub Aqua" in Wales until January 2016. "Sub Aqua" is a broad term encompassing both recreational underwater activities such as recreational diving and snorkelling, and competitive underwater activities including underwater sports as underwater hockey The WASAC was one of four NGBs representing "Sub Aqua" in the constituent countries of the United Kingdom. The others are the British Sub Aqua Club (England), the Northern Ireland Federation of Sub-Aqua Clubs (Northern Ireland) and the Scottish Sub Aqua Club (Scotland), with  the British Sub Aqua Club being the NGB for the United Kingdom; a role it has held since 1954. Although WASAC was responsible for underwater hockey (also known as Octopush), training and management of Wales national squads is controlled by Hoci Tanddwr Cymreig Underwater Hockey Wales (HTC UHW). The WASAC was based at Gwaun-Cae-Gurwen, Neath Port Talbot. The WASAC was replaced by the British Sub Aqua Club as the governing body for Sub Aqua in Wales from January 2016.
