Accents In Water®

Overview of the University of Colorado Clean Air and Clean Water Studies

Accents In Water’s® product design team continues to work on developing water features that require less maintenance and contains pathogen free water. We have concluded studies on our patent pending PathoBan AG254™ Anit-bacterial System* in cooperation with Dr. Mark Hernandez, Ph.D, PE, Principal Investigator, to identify the impact that a water feature has on its environment. The studies were performed at the University of Colorado at Boulder’s Level 3 Lab in the Department of Civil, Environmental, and Architectural Engineering.

*PathoBan AG254™ Anti-bacterial System is the combination of a patented inorganic, anti-micorbial coating and ultraviolet steriliziation to inhibit the growth of and over the course of time kill bacteria, viruses, and other microorganisms that are trapped in the water.

AIW – Science Summary

Accents In Water UV Inactivation Assessment Empirical (pdf)

This study utilized the following aerosolized pathogens:

Bacillus subtilis (non pathogenic Anthrax)
Mycobacterium avium (non pathogenic Tuberculosis)

The objective of this study was to measure the effective Clean Air Delivery Rate (CADR) of Accents In Water water features. The CADR testing was structured to measure the rate at which a water feature can render the environment free of airborne pathogens over a measured amount of time. Clean Air Delivery Rates are surprisingly effective and vary based on the size of the water feature. A 4′ x 8′ water feature will effectively clean 30 cubic meters of air per hour. Please see the study results for further clarification.

Clean Water Summary

This study utilized the following aerosolized pathogens:

Mycrobacterium avium (non pathogenic Tuberculosis)
Legionella pneumophila (non pathogenic Legionaires disease)
Staphylococcus aureus (non pathogenic Staph)

High levels of the above pathogens were aerosolized and introduced into a contained environment in 3 independent trials. Once electrostatically captured and contained within the body of water, the pathogen deactivation rate was consistently measured as 99% effective in a single pass.

Saniguard Study

All water features manufactured by Accents In Water are treated with Saniguard, the only anti-microbial treatment that meets the National Sanitation Foundation stringent requirements for anti-microbial efficacy.

Saniguard is a sodium activated silver compound which disallows microbial growth on treated surfaces. When combined with the use of ultraviolet sterilization, it creates a highly effective system that protects against microbial growth in the water feature.
