Understanding the “Splash Zone” in Healthcare Environments

In healthcare settings, sinks play a critical role in infection prevention. But there’s an often-overlooked risk that extends beyond commonly discussed factors like aerators.

It’s called the “Splash Zone.”

As highlighted in the video above, the splash zone refers to the area surrounding a sink where water can disperse, potentially carrying harmful bacteria into the environment.

The splash zone is the area around a sink where water droplets can travel when water hits the basin.

In some cases, this zone can extend up to three feet from the faucet, increasing the potential for contamination beyond the immediate sink area.

When water splashes or gushes from a faucet, it can spread bacteria that may already be present in the sink or drain.

This includes serious pathogens such as:

• Legionella
• Pseudomonas
• Other bacteria that pose risks to immunocompromised patients

In healthcare environments, even small exposures can have significant consequences. Managing how water behaves at the point of use is essential for maintaining a safe environment.

Effective splash zone management requires more than temporary fixes.

According to the approach outlined by Water Saver Solutions, best practices include:

• Using point-of-use laminar flow devices
  Designed to create smooth, controlled water flow that minimizes splashing
• Avoiding aerators in patient care areas
  Due to their risk of aerosolizing bacteria
• Proper faucet positioning
  Ensuring water does not flow directly into the drain where bacteria may reside
• Implementing compliant, long-term solutions
  Rather than relying on splash guards or basic restrictors

These strategies not only reduce splash but also support broader infection prevention efforts.

Managing the splash zone is an important part of a comprehensive water management plan.

When properly addressed, it helps:

• Reduce the spread of harmful bacteria
• Support infection prevention protocols
• Improve overall fixture performance
• Protect both patients and healthcare staff

As emphasized in the video, proactive management plays a key role in maintaining safe, compliant healthcare environments.

The splash zone may not always be visible, but its impact is real.

By understanding how water behaves at the point of use, and implementing the right solutions, healthcare facilities can reduce risk and strengthen their infection prevention strategies.

A smarter approach to water safety starts at the point of use, where water flow, fixture performance, and the “splash zone” all intersect.

By optimizing flow rates and ensuring controlled, consistent water delivery, healthcare facilities can significantly reduce splashing. This not only helps lower the risk of spreading of bacteria from the sink basin and drain but also supports overall infection prevention efforts and helps to reduce risks before they escalate.

When paired with proper fixture alignment and the use of laminar flow devices, this approach helps minimize the risks associated with splash zones, an often-overlooked factor in waterborne pathogen transmission.

Equally important is a structured, verifiable maintenance program. Through proactive, app-driven programs like FixtureCare®, healthcare organizations gain greater visibility and control over their water systems, helping ensure consistent performance, reduce variability, and address risks before they escalate.

According to Water Saver Solutions, this approach supports:

• Reduced splash-related contamination risks through optimized flow and controlled delivery
• Lower risk of Legionella and other waterborne pathogens
• Improved protection for patients and staff
• Support for ASHRAE 188 compliance through proactive, documented maintenance

By addressing critical details like flow behavior, fixture performance, and ongoing maintenance, healthcare facilities can strengthen their water management programs, creating safer, more controlled, and more resilient environments.

How the right flow rate supports patient safety, infection control, and sustainability in hospitals

The video above explains how healthcare facilities can optimize faucet flow rates to balance water efficiency, infection prevention, and operational performance.

In healthcare environments, even something as simple as a faucet plays a critical role.

Each faucet throughout a hospital serves a specific function, from patient bathrooms and nurse stations to soiled utility rooms and locker areas. The way water flows through these fixtures can directly impact both infection control and sustainability efforts.

That’s why determining the right flow rate is not a one-size-fits-all decision.

At its core, the “right flow” means ensuring that each faucet delivers the appropriate amount of water for its specific use, while balancing:

• Patient safety and infection prevention
• Water conservation and sustainability goals
• System performance and pipe health

At Water Saver Solutions, this approach is defined by three key actions:

Upsize. Downsize. Optimize.

Each facility and each fixture may require a different solution depending on how water is used within that environment.

Flow rate decisions impact more than just water usage, they influence the overall safety and efficiency of a healthcare facility.

Key considerations include:

• Infection Control
  Adequate water movement helps prevent stagnation and supports safer water systems.
• Patient Safety
  Proper flow reduces splashing and supports hygienic use in clinical and patient environments.
• Sustainability
  Optimized flow rates help reduce water waste and support conservation initiatives.
• System Performance
  Ensuring enough water moves through pipes helps maintain system integrity.

Finding the right balance between these factors is essential for healthcare facilities.

Not all faucets serve the same purpose, and flow rate requirements vary depending on the location and use.

Common hospital areas where flow rates should be evaluated:

• Soiled utility rooms
• Patient bathrooms
• Nurse stations
• Locker rooms

Each of these environments has different demands, which is why a standardized approach often falls short.

A common question is: Where should we start?

In most cases, a recommended baseline is:

1.5 gallons per minute (GPM)

This rate, aligned with EPA guidelines in many states, provides a strong starting point because it:

• Maintains sufficient water movement
• Helps prevent splashing
• Reduces unnecessary water waste
• Supports conservation efforts, especially in drought-prone regions like California

However, this is only a starting point, not a universal solution.

Optimizing flow rates requires evaluating each application individually.

You may want to downsize when:

• Supporting sustainability initiatives
• Reducing water consumption
• Minimizing unnecessary flow in low-demand areas

You may want to upsize when:

• Ensuring adequate water movement through pipes
• Supporting infection control strategies
• Addressing system performance concerns

The goal is to strike the right balance between efficiency and safety.

Because every hospital is different, achieving the right flow requires a data-driven approach.

We recommend starting with a comprehensive survey that evaluates:

• All faucets across the facility
• Showerheads and their usage
• Department-specific water demands

This process helps identify where adjustments are needed and ensures that flow rates are aligned with both operational goals and safety standards.

One of the biggest challenges healthcare facilities face is balancing sustainability with infection prevention.

Water Saver Solutions works closely with:

• Infection control teams
• Sustainability departments

to ensure that water-saving initiatives do not compromise safety.

The result is a coordinated approach that supports:

• Reduced water and energy usage
• Compliance with healthcare standards
• Safer environments for patients and staff

Optimizing faucet flow rates may seem like a small adjustment, but across a healthcare facility, it can have a significant impact.

By taking a strategic approach to water flow, hospitals can:

• Improve infection control efforts
• Enhance patient safety
• Reduce water and energy consumption
• Support long-term sustainability goals

Upsize. Downsize. Optimize.

Because in healthcare, every drop matters.

A smarter approach to water safety starts with optimizing flow rates across every fixture in a healthcare facility. By ensuring the right amount of water is delivered for each application, hospitals can support infection prevention, maintain proper water movement, and reduce unnecessary waste.

When combined with a structured, verifiable maintenance program, this approach gives healthcare organizations greater control over their water systems. Through proactive, app-driven FixtureCare, facilities can help reduce Legionella risk, support ASHRAE 188 compliance, and align sustainability initiatives with patient safety goals.

Water Saver Solutions, known as The H₂ROI People, helps healthcare organizations implement these best practices through its FixtureCare® program, designed to:

• Optimize flow rates across faucets and fixtures
• Reduce Legionella and other waterborne risks
• Protect patients and staff
• Support ASHRAE 188 compliance through proactive, app-driven maintenance

By addressing critical details such as flow rate optimization and fixture performance, hospitals can strengthen their overall water management programs, creating safer, more efficient, and more sustainable healthcare environments.

How smarter water management helps hospitals reduce costs, improve compliance, and protect patient safety.

The video above explains why Water Saver Solutions is known as the “H2ROI People” and how hospitals can turn water efficiency into measurable financial and operational benefits.

In healthcare organizations, water is often viewed simply as a utility expense. In reality, it should be treated as an investment that delivers measurable returns.

When hospitals reduce water waste and improve efficiency, the savings can be redirected toward critical priorities such as patient care, facility improvements, and operational upgrades.

According to ENERGY STAR, every dollar a nonprofit healthcare organization saves on utilities is equivalent to generating $20 in new revenue.

That means improving water efficiency can have a significant financial impact without requiring additional patient volume or new services.

H2ROI stands for “Water Return on Investment.”

The concept is simple: every gallon of water that is managed more efficiently produces value, not just through reduced water usage, but through real financial savings.

Hospitals often have enormous opportunities to improve water efficiency because of the scale and complexity of their operations. Healthcare facilities operate like small cities, running 24 hours a day, 365 days a year.

Water entering a hospital is distributed across several key systems throughout the facility.

Major areas of water usage include:

1. Medical Process Equipment

• Sterilizers
• Autoclaves
• Cart washers

2. Plant Operations

• Boilers
• Cooling towers
• Water softeners
• Reverse osmosis systems

3. Domestic Fixtures

• Faucets
• Showers
• Toilets

4. Food Service Operations

• Pot filling
• Dishwashers
• Cooking equipment
• Cleaning systems

Understanding where water is used is the first step toward identifying meaningful opportunities for savings.

Not all water systems use the same amount of water. Some systems offer much greater opportunities for improvement.

The largest areas of water consumption typically include:

• Cooling Towers

  • Represent approximately 40–50% of a hospital’s total water usage

• Domestic Fixtures

  • Account for roughly 25% of water consumption

Because these systems operate continuously, even small efficiency improvements can produce significant savings.

Effective water management requires more than guesswork. It depends on a strategic approach built on:

• Measurement of water usage
• Analysis of system performance
• Knowledge of where improvements can deliver the greatest impact

When these elements are combined, healthcare facilities can significantly reduce water waste while maintaining operational performance.

For nearly two decades, Water Saver Solutions has worked exclusively with healthcare organizations to help them understand water usage patterns and address the unique challenges hospitals face, including regulatory requirements, compliance standards, and bacterial risks within water systems.

The name “H2ROI People” reflects the mission behind Water Saver Solutions: helping healthcare organizations achieve a measurable Water Return on Investment while prioritizing safety and compliance.

For hospitals, water management isn’t only about reducing consumption, it’s about understanding how water impacts operations, patient safety, and infection prevention.

By combining expertise in healthcare water systems with a data-driven approach, Water Saver Solutions helps hospitals:

• Reduce water waste and operating costs
• Improve compliance with healthcare water safety standards
• Minimize risks associated with bacteria in water systems
