“Turn on your fourth-grade brain,” Community Relations Specialist Barbara Crow told a group of new Louisville Water employees. “I’m going to do this lesson like I do when I visit a school.”
The lesson, an activity added to the employee orientation agenda for the first time last year, involved experiments to see how different materials filter water. Using such items as rocks, sand, sponges, paper towels, and netting, participants filled coffee filters and observed the effects as dirty water poured through.
Some materials trapped dirt but blocked water flow, while others captured only larger debris. The new employees gained valuable insights into filtration processes.
This interactive approach echoes the pioneering work conducted at Louisville Water in 1896 by George Warren Fuller, regarded as the “father of sanitary engineering.” Fuller’s groundbreaking experiments established key principles: that settling water in a reservoir, followed by coagulation and filtration, results in a cleaner water supply for the community.
Crow emphasized that filters are important not only for the taste and appearance of our water but also to make sure it’s safe for the community to drink.
“We’re all about public health,” she told the new employees.
