The Pool Water Treatment Advisory Group was established as an independent entity in December 1984. PWTAG has a membership drawn from a wide range of relevant statutory, voluntary and
professional organisations with an interest in pool water treatment and pool users.
PWTAG is able to pursue its work without any commercial or other influence. It is a focus for debate and
improvement in operational and management standards in an area which comes under significant financial
and political, as well as technical pressure.
