Meet the Experts

Most people don’t think about what happens after they flush their toilet. As long everything is working fine, they don’t have to worry about it. The truth is that it takes a lot of science, hard work and dedicated professionals to make sure the toilets, sewers, stormwater systems and wastewater treatment plants are working every day of the year.
