Pool Plant Operation

CIMSPA Register of Pool Plant Professionals

The RoPPPs register recognises all those professionals who have qualified in pool plant operations and who have kept their knowledge up to date by attending a one day RoPPPs update seminar within 5 years of qualification (up to 31st July 2010) or 3 years of qualification (from 1st August 2010).


It is of benefit to employers, who can access the register to ensure all their staff are qualified. Improving standards of professionalism is CIMSPA’s way of helping to ensure that pools become safer, more hygienic and healthier for people to use in a world where increasing levels of positive healthy exercise is a major public health priority.

CIMSPA introduced the Register to raise the standard of competence in plant rooms across the country and assist employers who regard safe effective operation of pools as a priority, to meet the requirements of the Health and Safety Executive approved document 'Managing Health & Safety in Swimming Pools (HSG 179)'.

Water Sampling

Why test swimming pool water?

Microbiological contamination of the pool water can result in pathogenic (disease producing) microorganisms causing infections to bathers. These contaminants can be introduced into pool water from bathers, from the pool filters or occasionally from defects in pool engineering (e.g. that allow the water to be contaminated with sewage).

Tests should be performed monthly to monitor the presence of indicator micro-organisms. These can indicate operational problems that could result in infections. Additionally, tests should be performed:

  • before a pool is used for the first time;

  • before it is put back into use, after having been shut down for repairs;

  • if there are difficulties with the treatment system;

  • if contamination has been noted;

  • as part of any investigation into possible adverse effects on bathers' health; and

  • to validate changes made to the pool treatment regime, e.g. change in disinfectant, or frequency of addition, or engineering.

More frequent sampling will be necessary if there is a problem, or for particularly heavily loaded pools.

Hydrotherapy pools should be tested before being used for the first time and then once a week (as opposed to once a month with other types of pool) as the people, including staff, using these pools are immersed for longer periods and may be more vulnerable to infection.


Microbiological sampling should be performed by trained and competent personnel to prevent sample contamination. Microbiological analysis should be carried out in appropriately accredited laboratories, e.g. UKAS laboratories. The pH level and the concentration of free and total disinfectant in the pool water should be measured when the microbiological sample is collected. Microbiological samples should be taken beginning at a depth of 200 mm to 400 mm below the surface of the pool.


The results of routine microbiological sampling should always be interpreted in conjunction with:

  • chemical tests performed on site and/or in the laboratory at the time of sample collection; and

  • a review of the maintenance records for the pool, including records of the pH, residual disinfectant levels, mechanical failures and water appearance and other untoward events.

Samples should be tested for aerobic colony count, coliforms, Escherichia coli and Pseudomonas aeruginosa.
