Legionella Control In Hospitals

With our advanced water treatment and monitoring service, we are equipped to protect the most vulnerable from water borne diseases and ensure compliance for healthcare professionals and hospitals.

Hospitals and their water systems are often known as breeding grounds for Legionella. Unfortunately, those already suffering from illness or those who are immune-compromised have an increased risk of contracting Legionnaires’ disease, the disease most commonly associated with Legionella. Consequently, legionella control in hospitals is highly important.

ProEconomy have installed the copper and silver water treatment system, The Orca, in over 90 hospitals across the UK and have successfully controlled Legionella in all hospital sites. You can view our successful water treatment case studies below.

Alternatively, if you would like to discuss water treatment at your hospital or estate, contact our team today.

legionella control in hospitals
  • Basildon University Hospital

    It was concluded that Legionella could not be effectively controlled using a temperature regime alone and that copper and silver ionisation used in conjunction with the temperature system already in place was effective for Legionella control at this hospital. Legionella is still being controlled successfully at Basildon Hospital since the last data shown in the below case study.

  • Birmingham Heartlands Hospital

    Within a month of installation, the Orca system was proving to be very effective at Birmingham Heartlands Hospital. From the 21 sites we returned five positive samples, ranging from 100cfu/l to 2,000cfu/l. These results continued to improve and by the March 2008 all the samples we were taking were completely clean. A further advantage of reduced TVC levels were also realised in areas previously known to have high levels.

  • Solihull Hospital

    Following the success of the Orca at Heartlands, one copper and silver ionization system, with eight copper and four silver electrode chambers, was installed in January 2008. Of the 357 samples taken in the past four years, only six were positive for P. aeruginosa (1.7%). Meanwhile, no Legionella has been detected for the past 3 years (April 2014 - April 2017).

  • Devon Centre for Women’s Health

    One month after the installation of the Orca system, samples were taken from four outlets that were contaminated before the system activation and from six other outlets identified as being at risk of Legionella contamination. No Legionella were found in these samples, with silver levels of 0.039 to 0.115 mg/L.

    Following the success of the Orca system at Little Aston Hospital and Gatwick Park Hospital, the Orca copper and silver ionisation water treatment system was installed at Greenbank Road Liverpool Hospital in Liverpool, Methley Park Hospital in Leeds, and Dunedin Hospital in Reading. As can be observed in Table 2 in the below case study, the Orca system successfully reduced the number of positive Legionella counts at the hospitals.
