PWTAG Technical notes are updates or new material for the standards and guidance given in the PWTAG book, Swimming Pool Water and the PWTAG Code of practice and should be read in association with these publications.
- PWTAG does not formally approve particular branded products or processes. So any promotional claims along the lines of ‘PWTAG approved’ can be assumed to be bogus.
- PWTAG does, however, recommend types of product and processes. These will have been independently validated by at least one authoritative body acceptable to PWTAG, or proven in other ways. For example, many of the products and processes used in swimming pools were researched and established in the drinking water industry. Others are well established and proven over time in swimming pool practice, and often researched and evaluated by PWTAG.
