Water Hygiene

Providing the health, safety and hygiene of your water systems.

ACoP L8 Compliance

Legionella bacteria grows in warm water typically between 20 and 50 degrees centigrade, but proliferates fastest in stagnant water at 35 to 46 degrees centigrade.

At the heart of the Health and Safety Executive's ACoP L8 for control of legionella, is to undertake a risk assessment of the entire water system and implement a scheme of control.

Sampling and Analysis

Normally, the routine analysis of domestic water systems is not recommended by the ACoP L8.

However, under certain circumstances, such as where the temperature regime cannot be maintained, the testing for legionella and other organisms is seen as being essential in the overall control of a system.

Water Management Solutions

We can offer you a tailored programme of monitoring and remedial maintenance to ensure ongoing and consistent compliance with Health & Safety Executives Approved Code of Practice (ACoP) L8 and Technical Guidance HSG 274 & HTM 04-01 best practices.

Our Solution to Combatting legionella

We can undertake an assessment of your water systems, highlight any areas of potential risk and provide you with a detailed legionella risk assessment report.

We will make recommendations for the implementation of an effective monitoring and maintenance program including any remedial works identified.

Where a risk assessment is already in place, we can review this for you or undertake an audit.

Thermostatic Mixing Valves (TMVs)

Increasing hot water temperatures at outlets to over 50 degrees centigrade is necessary to control legionella bacteria, yet this can increase the risk of scalding.

TMVs will effectively avoid scalding, but must be correctly selected, installed, regularly serviced and maintained to prevent the proliferation of legionella.

Automated Legionella Compliance

Legionella risk assessments frequently call for taps to be monitored. In practice this means running them for two minutes and recording the temperature. This is a significant cost in man time and management. The records must be stored for years and the test regime will run indefinitely.

AquaCare have partnered with NFC Group who have developed an automatic flushing and temperature testing unit, that can be dynamically controlled on the Genius smart building platform. This allows tests to be scheduled according to needs and all the reports generated automatically whilst removing the risk of human error.
