Venturi system helps to 'beat the bugs'

Since its refurbishment in 2008/2009, the 'old' Saint Mary's Hospital has predominantly been used from 9.00 am to 5.00 pm weekdays (its Sexual Assault Referral Centre, or SARC, facilities are sometimes open evenings and weekends), presenting a significant water stagnation risk. During the trial of the Kemper KHS water flow management system, none of the 125 water samples analysed for Legionella and coliforms were positive, while just 11 of the 116 tested for Pseudomonoas spp exhibited the bacteria, only two exceeding Department of Health-set limits.
