• Water Safety

While a focus for the treatment of water systems for decades, water safety and risk management has become a particular emphasis over the last few years. From ASHRAE specifications, to CDC recommendations, and to government rules, laws, and regulations, the development of Water Safety Plans has become a requirement for owners of buildings with water systems such as cooling towers, fountains, spas and hot water distribution systems.  Through its AquaAnalytics Data Management, Service and Water Management Program, DuBois has the tools to effectively develop, implement, and execute Water Safety plans for your facility.

ANSI/ASHRAE 188 Water Safety Plan

The AquaAnalytics approach determines control measures – what to control and where – and then defines a monitoring program and corrective actions to minimize the risk of Legionella.

We can assist you in developing a custom Water Safety Plan for your facility to comply with ANSI/ASHRAE Standard 188-2018, “Legionellosis: Risk Management for Building Water Systems” and Centers for Medicare & Medicaid Services (CMS) S&C 17-30 June 02, 2017 memorandum.


ANSI/ASHRAE Standard 188 and CMS state that facilities must have a Water Safety Plan. AquaAnalytics assists you in executing your plan and provides a record of compliance.

All members of the water safety team have access to the most current version of the water safety plan, verification summary reports, analytical results, and validation summary reports.

The system gives you peace of mind that things are under control and that your data is backed up and always available.

Task Management System

Water Safety Plans are often complex – involving multiple people, with numerous task responsibilities, at varied frequencies. AquaAnalytics provides personalized task management views and automated reminders of all assigned tasks.
