Welcome to PWTAG – The Pool Water Treatment Advisory Group
PWTAG is a UK-based independent, non-commercial membership organisation, dedicated to raising standards in pool water treatment. Our work over the last 35 years has made us the authoritative source of standards and guidance in the management of swimming, spa and hydrotherapy pools.
Our book Swimming Pool Water: treatment and quality standards for pools and spas is the definitive guide while our Code of Practice is a vital industry text.
We collaborate with government agencies and professional and technical specialist bodies. Currently 20 of these form our core membership. Their representatives are crucial in setting and maintaining standards for the management of safe pool water.
