Types of Pools

The HSE categorise Pools into various types that require different control procedures, such as:

Swimming Pools that include;

Spa Pools, also known as;

Spa Pools contain;

Waterman can provide complete monitoring & maintenance programmes and innovative solutions to maintain all types of Pools. 

Balance Tanks

A Swimming Pool Balance Tank is an important but often forgotten feature in the Pool Filtration System that plays a significant role in maintaining a constant water level in pools. It is situated in between the filtration system and the pool tank itself, providing an intermediate to hold the water displaced by bathers entering the pool before releasing the water back into the tank as bathers leave to give a constant water level.

Due to its set-up, the balance tank accumulates a large amount of debris and contaminants. This provides a prime breeding ground for a variety of bacteria. If not cleaned regularly can pose a serious threat to pool hygiene.

Waterman are able to provide the full monitoring & maintenance services of balance tanks as recommended by the guidance (PWTAG Code of Practice, HSG179, HSG282).

Microbiological Testing

Sampling should be carried out regularly to monitor the presence of microorganisms. Testing should also be undertaken in the following circumstances:

More frequent sampling will be necessary if there is a problem or for particularly heavily loaded pools. Hydrotherapy pools, even those not in a healthcare setting, should be tested weekly.

Microbiological testing should be performed only by competent and accredited personnel at a UKAS laboratory.

Waterman can provide a large selection of water tests, such as Microbiological, Metal, Corrosion and Chemical. We use Mercian Science who are regarded as one of the best in their industry and are UKAS accredited.

Routine Monthly Water Analysis

Waterman can carry out all types of Water Analysis, such as:

What to do with Positive Samples

Helping You Take Control of Your Water Systems.

Waterman will monitor all water samples through our LIMS (Laboratory Management System) which allows us to constantly monitor the samples on the central data base. We will then report any positives or potential issues to our clients advising of what should & shouldn’t be done to comply with guidance and help our clients ensure the hygiene and satisfaction of their customers.

Acting On Failures / Pool Closure

If a result is unsatisfactory, a preliminary investigation should be undertaken and the test should be repeated as soon as practicably possible.

If the second result is also unsatisfactory, the pool’s management and operation should be investigated and the test repeated.

If the third result is still unsatisfactory, immediate remedial action is required, which may mean closing the pool.

The pool should be closed if there is chemical or physical evidence of unsatisfactory disinfection.

The pool should be closed if microbiological testing discloses gross contamination, which means one of two things:

Sample Results


Within a pool facility there are many potential uses of water where users and those in the vicinity may be exposed to hazards with the potential to cause injury and waterborne illness.

In general, the importance of a balance between public health demands and consumer acceptability are similar for both drinking and swimming waters. Disinfection cannot be compromised but can be aimed towards minimising both disinfectant levels and the formation of unwanted substances, including disinfection by-products.
Along with filtration and chemical dosing, balance tank cleaning is key to keeping the pool water well balanced and safe.

Balance tank cleaning, is recommended by PWTAG (Pool Water Treatment Advisory Group). Balance tanks should be inspected at least once a year and cleaned as necessary. Debris should be removed and inner surfaces brushed and flushed down with 10mg/l chlorinated water, which can be returned to the circulation system via the filters.
