Water Testing, Analysis and Sampling


uRisk provides water testing, analysis and sampling for a wide range of bacterias, metals, chemistry from all ranges of water systems including: drinking water, hot and cold domestic supply, cold water storage tanks, swimming pools and spa’s, closed systems, lakes and reservoirs and anywhere else there is water.

Water Testing and the Importance of a Sample Strategy


Water testing may appear to be a simple process, you fill a water bottle and test its content. But without careful consideration and planning it can become extremely costly, time consuming and problematic. Below is a range of considerations that must form part of any sampling plan:


  • Reason for Sampling and Frequency of Sampling
  • Sampling Locations
  • Time of Sampling Post Clean and Disinfection (e.g. new water supply or tank clean)
  • Water Assets that Require Sampling (e.g. tanks, showers, pools, equipment)
  • Water Test Type
  • Sample Type (pre or post flush, biofilm or dip sample)

Why carry out routine water sampling?


Routine water sampling is the most effective way to determine water quality. Without water testing, analysis, sampling you are unable to identify water quality and therefore you are unable to determine whether your water management and legionella control is sufficient.

With periodic water testing you are able to demonstrate that your water management and legionella control procedures are suitable and the water in your water system is fit for purpose.

All our water samples are tested in UKAS accredited laboratories as standard. We are able to carry out tests on a wide range of microbiological samples and chemical testing services.

Flexible Water Sampling Services


uRisk provides a range of water sampling services from DIY test kits to one off sampling services (where a trained engineer carries out the sampling) or a routine water sampling programme carried out by trained engineers.

All sampling visits are inclusive of full water system inspections, results explanation, recommendations and certification.


Water Sampling Bottles


Water sampling bottles are sterile bottles treated with sodium thiosulphate which aims to neutralise the effects of residual chlorine in the sample bottle.

All samples should be labelled with the sample number, date, sample type, company name, sample location, sample system (hot or cold), water temperature. Chemical samples will also need to be taken using the appropriate bottles.

Water Sampling Competence


All water hygiene engineers have been trained to take samples in a manner that is least likely to contaminate the sample. It is important that the person undertaking sampling has been trained and is competent in sample taking.

There is more to sampling than filling up a bottle of water. The sample locations are crucial to ensure a true representation of your water system is analysed. Pre and post flush sampling can impact your results. Knowing whether the sample should be taken immediately (pre-flush) or if a sample should be taken post-flush can have an important impact on the results too. Contamination may also impact your sample results and water system if incorrectly taken.
