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.

Standards and Guidance

PWTAG guidance is based around two key elements; the Code of Practice and Swimming Pool Water, a book produced by PWTAG which is an essential guide for pool and spa operators.The PWTAG Code of Practice provides pool operators with a structured plan for the technical operation of their pool.

The code ensures that the technical operation of a pool meets quality standards that provide a healthy experience for swimmers using recognised and established practices, techniques, engineering and design.

For this reason, all UK pools are encouraged to follow it.

Pool Technical Staff Training

All pools should have some form of staffed presence responsible for their technical operation and supervision.

PWTAG have established syllabuses for two roles – Swimming Pool Technical Operator (SPTO) and On-Site Designated Supervisor.

We also work with four approved training organisations to deliver these qualifications nationwide.

Becoming a PWTAG member is the best way you or your organisation can continue to champion the latest standards for swimming pool water.
