Wastewater is no laughing matter. Especially when there’s too much of it. During storms and times of heavy runoff, partially or untreated sewage can flow into ditches, streams, rivers and lakes. Which isn’t too pretty if you’re a fish or somebody who drinks water. The solution to this disgusting mess has been framed as an expensive one, “Communities will need hundreds of billions of dollars in coming years to construct and upgrade wastewater infrastructure,” according to the U.S. Government Accountability Office.
