Technical Notes
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 keeps pool operators up to date by providing guidance through these technical notes on the issues of the day.
Combining PWTAG’s specialist expertise and published scientific data, we aim to optimise swimming pool technical operation.
