wastewater

When the City of Kalamazoo built its first wastewater treatment plant to handle the raw sewage that had previously been dumped directly into the Kalamazoo River, it used the simple process of allowing solid material settle to the bottom of collection tanks. But with residents and businesses using more chemicals these days, the process needed to clean up sewage water is much more complex. It is admittedly not something most people think about, or want to. But it is necessary to prevent pollution.
