SPATA members include pool construction companies and suppliers which provide filtration, heating, water treatment systems, pool covers, pool enclosures and pool equipment, for instance. As part of the SPATA membership, contractors are provided with a comprehensive set of Standards to provide guidance on pool construction standards expected by industry experts.

All SPATA pool builder members will be part of an inspection programme to periodically check on the quality of the work undertaken.
