Coronavirus (COVID-19) Customer Statement

03 April 2020

At Aquacare, Health and Safety is our top priority. This is why we are taking proactive measures to protect the health and safety of our employees their families, clients and the public during this difficult time. We continue to monitor government advice and industry guidance to make changes to our working practices with regular communications to all clients.

From Monday 6th April AquaCare are suspending all non-essential works for two weeks. This will be reviewed on a weekly basis by the Senior Management Team.

Many of Aquacare’s services are critical, preventing Legionella and other waterborne diseases. If you have high risk plant (cooling towers / steam boilers) you will be contacted by your Aquacare account manager.

If you were expecting a visit in the next 2 weeks from AquaCare to undertake tasks that are not covered in the above i.e. domestic water systems and the associated monitoring tasks included but not limited to the below these will not take place:

  • Weekly Flushing
  • Temperature Monitoring
  • Shower Head Cleaning / Disinfection
  • Tank Inspections / Cleans
  • Water Sampling
  • TMV Servicing
  • Remedial Works
  • Legionella Risk Assessments

If you do have any questions or queries then please do make contact via

We will continue to support and offer advice to all clients and suppliers and continue to inform & update on any changes or decisions made.
It may become necessary for your premises to either close for an extended period or for external persons and contractors not to be permitted access. Although the COVID-19 virus may take priority at this time, it would both be prudent and responsible to remain in fulfilment of your duty of care for those within your property in regard to Legionella control.

The expectation for evaporative cooling systems is that they will be maintained as usual or switched off safely.
Please find some key areas of best water hygiene practise that you can use to help control Legionella within your water systems.

  1. Ensure good usage and turnover throughout – any area or outlet infrequently used for a period of and no greater than 7 days should be flushed at least Weekly until the temperature at the outlet stabilises. If possible, drop stored water levels in tanks to maintain <24 hours storage as weekly flushing may not be sufficient. The flushing level may need to be increased due to your building occupancy. 
  2. Prevention of aerosol – Legionella is a respiratory disease caused from the inhalation of aerosol. When flushing outlets, every precaution should be made to minimise any aerosol creation. This can be done by turning on taps slowly and removing shower heads where possible. Where possible reduce or remove the creation of aerosol within your system.
  3. Ensure good temperatures throughout – hot water should be stored at 60ׄ°C and distributed so that all associated outlets reach over 50°C within 1 minute (55°C within healthcare premises). Cold water should be stored at under 20°C and distributed to all associated outlets at under 20°C.
  4. If possible, remove sources of heat and external thermal gain
  5. If fitted, consider temporarily increasing levels of potable water treatment dosing – consider other consequences of this such as corrosion and make the decision on balance of benefit  
  6. If controls are lost (temperature, biocide levels, etc). Please contact your Account Manager
  7. Consider other short term measures to keep remaining occupants safe such as point of use filters at designated locations with other areas shut off.
  8. Buildings that are temporarily shut down (mothballed) should follow the guidance in HSG274 Part 2 paragraphs 2.50-2.52:
    1. Where a building, part of a building or a water system is taken out of use (sometimes referred to as mothballing), it should be managed so that microbial growth, including legionella in the water, is appropriately controlled. 
    2. All mothballing procedures are a compromise between adequate control of microbial growth, the use of water for flushing (while avoiding waste) and degradation of the system by any disinfectant added. Where disinfectants are used, these should leave the system fit for its intended purpose.
    3. In general, systems are normally left filled with water for mothballing and not drained down as moisture will remain within the system enabling biofilm to develop where there are pockets of water or high humidity. The water in the system also helps to avoid other problems associated with systems drying out, including failure of tank joints and corrosion in metal pipework. The systems should be recommissioned as though they were new (i.e. thoroughly flushed, cleaned and disinfected) before returned to use’. 
  9. If the building is still partially in use take additional measures to keep the remaining occupants safe
  10. Do not drain down pipework  
  11. Lock off, place signage on doors and otherwise advise potential users that the system has been taken out of use.
  12. Have a plan in place for recommissioning the water system

If you have any queries on how best to control Legionella within your water systems at this time, then please get in touch.

Please be advised that our offices are currently closed, however you can still call your account manager directly or email us via

Aquacare would like to take this opportunity to thank you for your continued support and we hope to continue to work with you through the coming weeks and months to find the best plan for controlling Legionella within your premises.

For extra information on Legionella and Legionnaires disease please refer to the ACoP L8 and HSG274 parts 1, 2 and 3 guidance documents, which can be found online.
