After several high profile incidents involving legionella and stored water, McDonald Engineers embarked upon a small scale project to understand the impact of copper’s unique bacteria killing properties.
The experiment was simple. We filled 2 clear glasses with water and placed a section of foam material in each glass. We then placed a 7cm x 4cm piece of copper in one of the glasses, then sat back and waited for the magic to happen.
After only 2 weeks, bacteria could clearly be seen in one of the glasses, whereas the glass with the copper was absolutely clear.
