What Does Our Risk Assessment Process Involve?

Businesses that operate water systems or cooling towers, or both, require annual water risk assessments under guidance from the Health and Safety Executive (HSE).

A WaterCare Solutions risk assessment is designed to help you spot any potential risk areas within your water system and Cooling Towers, both of which are potential hotspots for nasty bacteria such as Legionella, and give you practical steps to keeping your systems safe and compliant.

1. Identify site assets and understand the risks from water-born infections in your workplace

2. Produce a suitable schematic drawing

3. Identify and appoint responsible persons and have a clearly defined responsibility structure

4. Implement a written scheme of control to minimise associated risks and provide protection

5. Ensure all staff are competent and suitably trained to carry out their appointed tasks

6. Review the assessment at regular intervals or when there is reason to believe it is no longer valid

Who Is Legally Required To Carry Out A Risk Assessment?

The responsibility for carrying out a water risk assessment will typically fall on the owner or operator of the premises where water systems are in use.

However, requirements can vary from business to business. If you’re unsure about how the regulations affect your organisation, talk to the experts at WaterCare Solutions today – we’re always on hand with free, friendly advice.

The recommended time frame to renew a water hygiene risk assessment is once every 12 months, but some setups will require more frequent assessments, and any changes made to your system should also be assessed as soon as possible.

Legionella risk assessments specifically are required every two years by law, but certain factors might necessitate more frequent assessments, such as if a facility houses elderly or otherwise immuno-compromised people.

When should a water risk assessment be reviewed?

To guarantee that a water risk assessment remains effective, it should be reviewed on a regular basis. Reviews should occur when there are major modifications to water systems, procedures or laws that could affect the assessment’s conclusions.

It is standard practice to do an annual review, at the very least, to ensure that control measures are up-to-date and any emerging risks are addressed promptly.

What do I need to consider with a water risk assessment?

Conducting a Water Risk Assessment (WRA) is crucial for businesses to manage water systems effectively. It's important to identify the purpose of your WRA, whether it's for a newly constructed facility, routine check after a few years, or addressing a recently identified risk.

Understanding these goals, particularly for compliance with UK laws, ensures a more effective outcome with the assistance of Watercare Specialists.

Water Surveys and Dissemination

Our highly trained risk assessors will produce an asset register of wall water systems on-site. We will evaluate the compliance of the installation to discover if there are risks of bacterial growth or dissemination.

If we discover any risks, we will create a detailed plan and perform the necessary steps to eliminate them and prevent them from returning. These risk-rated remedial actions come with photographic evidence as appropriate and a cross-reference to the relevant piece of legislation to ensure full compliance.

Our finished report will contain a simple schematic drawing and monitoring regime for the ongoing management of risk in your water system. Our team will:

1. Control scale formation

2. Protect against the damaging effects of corrosion

3. Reduce fouling

4. Control microbial growth like the Legionella bacteria and Pseudomonas

5. Control pH

6. Treat wastewater prior to discharge

Water Risk Assessment FAQs

It is essential for all businesses to test their water systems for Legionella and other potential risks every two years. Certain sectors such as healthcare and hospitality, with facilities including hospitals and care homes will require a WRA much more frequently.

These facilities house people with compromised immune systems where, if Legionella bacteria is found, will have a significantly larger impact on their health. Therefore, these facilities need to be tested annually.

Will you be assessing individual facilities or are you including your whole chain of value? Consider the scope of your water risk assessment to ensure the proper process is carried out.

Existing documentation of past water risk assessments should be available and evaluating these can help identify any missing information and help develop a comprehensive WRA, enabling a more effective management control scheme.

We are here to offer any guidance and solutions you may need regarding the considerations of a WRA and where to start.

UK standards dictate a Legionella risk assessment must be performed every two years. However, there are certain factors and situations when a WRA is required sooner, including:

  • If a facility or business’s occupants are high risk, such as the elderly or those with a weakened immune system
  • If changes are made to the water system, such as the pipework and other assets
  • When new UK regulations are published with new alterations and recommendations
  • If there is suspicion of a Legionella outbreak, or if positive results are found

When the current managing processes and control scheme are no longer effective for your water system

Legionella (or bacterial contamination) typically smells musty, like rotten eggs or sulphur when your water is contaminated. This is from the hydrogen sulphide that is produced as a volatile gas. Hydrogen sulphide is not harmful in low doses, however, in high amounts, the smell and taste of your water will be particularly unbearable.

Bacteria will thrive in boiler systems that are not kept at a hot enough temperature – with bacteria growing between 20-45°C – increasing the risk of your system becoming infected with Legionella. If you notice a rotten egg smell coming from your water systems, get in touch with a professional water treatment company

There are several disinfectants for the treatment and eradication of Legionella. Oxidising agents, such as chlorine, chlorine dioxide, chloramine, and ozone are the most common and effective disinfectants used to treat the bacteria.

The effectiveness of disinfectants against Legionella will depend on factors including the condition of the Legionella as well as the characteristics of the water, such as the temperature and pH level.

Boiling water is an effective way of killing Legionella bacteria, however, it is not a practical method for disinfecting entire water systems and can be logistically challenging. Legionella cannot survive in water that has been brought to a boil and maintained above 70°C for several minutes.

WaterCare Solutions performs the necessary and practical methods of disinfecting your water systems of Legionella and other types of harmful bacteria.

The temperature range where Legionella develops and is found is between 20-45°C. Below 20°C, the bacteria is still dormant, but for anything exceeding 60°C the bacteria will not be able to survive and will be killed.

This is why it’s vital to keep your boiler system or hot water storage cylinders, for example, storing your hot water at 60°C or higher, with cold water stored and distributed below 20°C.

You can find out if your water has Legionella by hiring a professional service to carry out tests. They will have the expertise and equipment to test water samples for the presence of Legionella bacteria. There are also do-it-yourself testing kits which must be followed exactly according to the instructions.

Also, conducting a risk assessment of your water’s temperature, assessing if there is any stagnant water, scale, sediment or biofilm in your water system can identify if any Legionella bacteria is present. It is important to consult with experts who can provide the best services to ensure the safety of water systems, and to know if your water has Legionella bacteria.

There are several ways to get rid of Legionella in drinking water as well as in building water systems. Proper maintenance is key to ensure the risk of Legionella developing is kept at a minimum. First, creating a Legionella control plan identifying the schematics of your water system, with every outlet, pipe and feature, will help identify where your system is most vulnerable.

Disused pipes should be removed as they enable the development of stagnant water and the growth of biofilms where Legionella can live. Regular flushing of your taps and showers can eliminate stagnant water also. Additionally, keeping water temperatures at safe and acceptable levels is a must – with cold water kept below 20°C and hot water stored and maintained at 60°C or above.

If Legionella is found in your drinking water, seek out a professional water treatment service, such as WaterCare Solutions to provide the best solutions to disinfect your water system.

Running your water system, also known as flushing, can help prevent the development of Legionella, while also significantly reducing the risk. This can be done by simply turning your taps and other water outlets and letting them run continuously for five minutes.

This should also be carried out for infrequently used taps, showers and eye wash stations as it will help prevent stagnant water.

Taps should be flushed for Legionella at least weekly to reduce the risk of Legionella. Commercial properties with a higher risk, such as hospitals, may need to do this at least twice a week.

A commercial Legionella risk assessment is a comprehensive evaluation of commercial or industrial facilities to assess the risk of Legionella bacteria growth and transmission within water systems. Legionella is a harmful pathogenic bacterium that can cause the severe respiratory illness known as Legionnaires’ disease.

A commercial Legionella Risk assessment performed by the experts at WaterCare Solutions will involve identifying potential sources of Legionella, including cooling towers, hot water systems and showers.

We can also evaluate the water system’s design and operational factors that could promote Legionella growth. We will collect water samples and test them to detect any harmful bacteria and develop a risk management plan to outline recommendations, modifications and maintenance protocols to reduce the risk of Legionella developing in your water system.

Legionella testing should be done regularly, and it is standard practice to perform a risk assessment annually. Both a Legionella and water risk assessment should be performed if there are any major modifications to your water system.

Other factors that determine the frequency of tests include any changes or new UK regulations, if you suspect an outbreak of Legionella and when the current managing process and control scheme are no longer effective.

While there is no specific length of time a Legionella risk assessment is valid, we recommend booking an assessment annually. This ensures maximum safety of your water system. Your most recent risk assessment may no longer be valid if your water system has gone under any alterations or modifications, as well as if any new UK legislation about risk assessments is released.
