Why is flushing water outlets in healthcare facilities so important?
In healthcare settings, maintaining a safe and hygienic water supply is vital for protecting patients, many of whom may be vulnerable to infection. A commonly overlooked but crucial part of water safety management is the routine flushing of water outlets such as taps and showers. This process helps eliminate stagnant water where harmful bacteria can thrive. If outlets are not flushed regularly, dangerous microorganisms like Legionella, Pseudomonas and nontuberculous mycobacteria can build up in the system, posing serious health risks.
What are the risks of water stagnation?
When water sits unused in pipes or outlets, it becomes stagnant and creates ideal conditions for bacterial growth. Warm, stationary water can foster biofilms—protective layers that harbour pathogens and help them multiply. One of the most serious threats is Legionella pneumophila, which causes Legionnaires’ disease, a potentially fatal respiratory infection. In hospitals and care facilities, another concern is Pseudomonas aeruginosa, which can lead to severe infections in patients with weakened immune systems.
How does flushing help control bacterial growth?
- Eliminates stagnant water: Regular flushing ensures old water is replaced with fresh, treated supply.
- Disrupts Biofilm: Flushing helps to break down biofilms that form on the inner surfaces of pipes, limiting areas where bacteria can take hold.
- Supports disinfection: Flushing restores disinfectant levels (such as chlorine) that may degrade in stagnant water, helping maintain microbiological control.
- Manages temperature: Keeping water moving helps regulate temperature, discouraging bacterial growth - especially in warmer environments
- Removes sediment: Sediments can build up in the system and shield bacteria from disinfectants. Flushing helps clear these out.
- Improves oxygen levels: Introducing fresh water adds oxygen to the system, which can inhibit anaerobic bacteria.
- Dilutes contaminants: Any substances that may have entered the system are diluted through flushing, reducing their impact.
- Maintains overall water quality: Consistent flushing maintains the cleanliness and safety of the water network
Why must healthcare facilities implement and follow flushing routines?
- Protecting patients: Many individuals in hospitals or care settings have compromised immune systems, making them more susceptible to infections from waterborne pathogens.
- Prevention of healthcare-associated infections (HAIs): Legionella and other bacteria can cause HAIs that are preventable with proper water management practices.
- Meeting compliance standards: Irish healthcare providers must adhere to water safety regulations and documented management plans, including flushing procedures.
- Cost-effectiveness: Preventing infections is far less costly than treating them or dealing with legal consequences of an outbreak.
- Safeguarding staff: Not only patients, but also staff can be exposed to waterborne hazards. Flushing helps keep everyone safer.
- Crisis prevention: Proactive flushing can prevent water quality incidents that might lead to serious operational or health issues
- Continuous improvement: Staying up to date with water hygiene practices and innovations supports better outcomes and resilience in facility management.
Regular flushing is a key measure in stopping the spread of harmful bacteria. It’s vital that Irish healthcare facilities establish and maintain strict flushing schedules—especially for outlets that are used infrequently or located in sensitive areas such as patient rooms, staff wash stations, and public toilets. This is even more critical following any plumbing issues or periods where outlets have not been in regular use.
