Legionella Water Safety Plans

Legionella Water Safety Plans

Protect your building, staff, and residents with expert Water Safety Plans designed to prevent Legionella outbreaks and ensure compliance with Ontario’s regulations.

Why Develop a Legionella Water Safety Plan?

A Water Safety Plan (WSP) is a proactive, structured program that helps organizations identify, manage, and minimize risks within their water systems. For property managers, healthcare facilities, hotels, schools, and industrial sites, implementing a Legionella Water Safety Plan is one of the most effective ways to safeguard public health and comply with Ontario’s evolving safety standards.

Legionella bacteria thrive in warm, stagnant water systems—such as cooling towers, hot water tanks, HVAC systems, and decorative water features. When inhaled through water droplets, Legionella can cause Legionnaires’ disease, a serious and sometimes fatal respiratory illness.

Failure to control Legionella risks can lead to liability concerns, regulatory penalties, and outbreaks. Ontario’s Public Health Act and Building Code emphasize the importance of risk assessment, monitoring, and corrective action. A customized Water Safety Plan for Legionella provides you with clear, documented strategies to remain compliant and protect the people who rely on your facility’s water systems.

Our Process Includes:

  • Full risk assessment of your building’s water systems

  • Identification of high-risk areas such as cooling towers and large plumbing systems

  • Implementation of monitoring and control measures (flushing, disinfection, temperature control, biocides)

  • Legionella testing schedules tailored to your facility type

  • Staff training and ongoing compliance support

  • Comprehensive documentation for audits and inspections

By partnering with Canadian Water Compliance, you’ll have peace of mind knowing your Water Safety Plan aligns with best practices recommended by WHO, Health Canada, and Public Health Ontario.

Who Needs a Legionella Water Safety Plan?

Legionella Water Safety Plans are critical for:

  • Hospitals, long-term care facilities, and seniors’ residences

  • Hotels, resorts, and office towers with complex plumbing systems

  • Industrial sites with process water or humidifiers

  • Schools, universities, and other institutions with high occupancy

  • Buildings with cooling towers, fountains, hot tubs, or decorative water features

If your facility relies on water systems where Legionella can thrive, a proactive Water Management Plan is not optional—it’s essential.

Frequently asked questions

What is a Water Safety Plan (WSP)?
A Water Safety Plan is a proactive, documented program that identifies hazards in a building’s water systems, sets control measures, and defines monitoring, corrective actions, and recordkeeping. It helps prevent Legionella and other waterborne risks from source to tap.
What is a Legionella Water Safety Plan?
A Legionella Water Safety Plan focuses specifically on preventing Legionella growth and transmission. It covers risk assessment for plumbing, hot water systems, cooling towers, decorative features, and humidifiers, with controls such as temperature management, biocides, disinfection, and flushing protocols.
Who needs a Water Management Plan in Ontario?
Hospitals, long-term care and retirement homes, hotels, office towers, schools and campuses, industrial sites using process water or humidification, and any buildings with cooling towers, hot tubs, or decorative fountains benefit from a documented Water Management Plan.
What’s included in your Water Safety Plan service?
We provide a site review and risk assessment, system schematics, control measures (temperature, disinfection, flushing), Legionella testing schedules, action thresholds and remediation steps, staff training, and compliance-ready documentation and logs.
How often should Legionella testing be performed?
Frequency depends on system type and risk: cooling towers are typically tested more frequently (e.g., monthly or per local guidance), while domestic systems are tested based on risk tier and occupancy. Your plan sets a schedule matched to your building and Ontario best practices.
What happens if Legionella is detected?
Your plan specifies response actions and thresholds—such as targeted flushing, thermal or chemical disinfection, system cleaning, retesting, and communication. We guide you through remediation and documentation to demonstrate due diligence.
How long does it take to develop a WSP and what does it cost?
Most buildings receive a completed plan in weeks, depending on size and system complexity. Pricing reflects scope, number of systems, and testing frequency. Request a quote for a detailed timeline and cost.
Does a Water Safety Plan help with Ontario compliance?
Yes. A documented plan, with monitoring and records, supports compliance with Ontario expectations and local public health directives, and helps demonstrate due diligence during audits or inspections.
