Why Stagnant Water
is a Major Risk

Legionella bacteria thrive in warm, stagnant water

Particularly in the 77–113°F (25–45°C) temperature range. Buildings with low water usage, such as schools, nursing homes, hotels, or offices, are especially vulnerable. Safe, flowing water is critical for keeping this risk under control.

How Noah Helps Prevent Legionella

Reduces Water
Stagnation

Auto‑flushing moves water regularly, disrupting the ideal conditions Legionella bacteria need to grow. Flushing is a standard preventative action endorsed by guidelines

Maintains Disinfectant
Residuals

By replenishing disinfectant in pipes— like chlorine or chloramine—Noah helps maintain a protective water barrier. Studies confirm this method boosts chlorine residuals in plumbing .

Stabilizes Water
Temperature

Noah’s routine flushing minimizes water temperature fluctuations, preventing water from lingering in the Legionella “growth zone”. Even simple flushing with cold or hot water shows measurable bacterial reductions

Proven Science, Embedded in Every Flush

Studies—including those from Frontiers in Water and the EPA—back Noah’s flushing strategy for Legionella prevention:

  • Regular flushing lowers Legionella counts in water, especially in first-draw samples
  • Spot flushing boosts residual chlorine and disinfectant levels in dead-ends
  • Flushing remains one of the best non-chemical Legionella control methods

Where Refuge Meets Risk
And Noah Makes a Difference

Schools &
Daycares

Reduce risk in underused classrooms, drinking fountains, and kitchen areas—especially after breaks or shutdowns.

Hotels &
Offices

Prevent Legionnaires’ disease during periods of low occupancy or seasonal downtime. Keep water moving in guest rooms, lobbies, and remote bathrooms.

Municipal &
Public Buildings

Protect water in libraries, fire stations, parks facilities, and city offices—where water systems often sit idle on nights/weekends.

Hospitals &
Medical Centers

Critical settings with immunocompromised populations. Auto-flushing reduces water age in patient rooms, surgical wings, and infrequently used faucets—without burdening staff.

Nursing Homes &
Long-Term Care

One of the highest-risk Legionella environments, per CDC. Automated flushing supports compliance with CMS and ASHRAE 188 while safeguarding vulnerable residents.

Why Temperature and Water Movement Matter

Legionella bacteria grow best in warm, stagnant water—particularly between 77°F and 113°F (25–45°C). As the chart shows, water that stays within this range for too long can create ideal conditions for bacterial growth. Keeping water moving and ensuring proper temperature control are key strategies recommended in public guidance.
