8 FLUSHING OF HEALTHCARE WATER SYSTEMS – A ‘NECESSARY EVIL’? Dr Nick Hill, Authorising Engineer (Water) at Water Quality London, sets out the purpose, methods, benefits, shortcomings, and pitfalls, of flushing taps and showers as part of the control process for Legionella in healthcare water systems.


15 WHAT ARE THE BARRIERS TO SAFE WATER IN HEALTHCARE?


Jimmy Walker, of water hygiene and safety consultancy, Walker on Water, previously scientific leader in Water Microbiology and Decontamination at Public Health England, and Dr Mike Weinbren, a consultant medical microbiologist, discuss some of the fundamentals of best practice in keeping hospital water supplies in a safe, clean, and hygienic condition.


23 DON’T ASSUME THAT OTHERS UNDERSTAND YOUR SYSTEM


Dr Susanne Surman-Lee, a State Registered Consultant Clinical Scientist, and director at independent public health consultancy, Leegionella Ltd, believes many of the problems surrounding poor water quality in healthcare are ‘due to a lack of ownership, lack of detail in contracts, and poor understanding and training of those involved’.


29 WHY SUSTAINABLE DRAINAGE SYSTEMS MAKE GOOD SENSE Kristen Guida, Manager at the London Climate Change Partnership, explores some of the practical, environmental, and reputational benefits to healthcare facilities of Sustainable Drainage Systems (SuDS), particularly in better rainwater and surface water management.

32 APPLYING FIRST PRINCIPLES TO HYGIENIC WASHROOM DESIGN


A recent review of existing Department of Health infection control guidance caused Carole Armstrong, Marketing and Communications manager at Delabie UK, to reflect that ‘we don’t need to reinvent the wheel – existing guidance already provides an excellent starting point for best practice’.


37 ADDRESSING THE BASICS OF SAFE DRINKING WATER HYGIENE


Chris Rhodes, associate director, Kemper UK & Ireland, and Frank Schmidt, International Market developer, and Timo Kirchhoff, head of Product Management, at Gebr. Kemper GmbH + Co. KG in Germany, consider some of the challenges in maintaining healthcare water supplies in a safe and hygienic condition that minimises the risks of growth and proliferation of potentially hazardous waterborne pathogens.


41 TIME FOR A UNITED APPROACH ON SAFE WATER DELIVERY Three years ago in HEJ, Bristan commissioned a white paper, ‘Your Views: Infection Control or Water Delivery’. Bristan specification product manager, Chris Tranter, revisits the report’s key findings, and reflects on the fundamental, yet unresolved, issues it raises.
