Are water reclamation facilities necessary?

Prior to current water reclamation techniques and technology, people had to worry about typhoid, cholera, and other infectious diseases that were commonly transmitted by unsanitary water. Water reclamation facilities serve primarily to protect the health of the general population by ensuring that water supplies remain clean. In the world today, people live a lot longer than they used to and higher population concentrations result in increased organic loads to waterways from various sources. Water reclamation facilities provide a cleaner, safer environment by reducing the organic load and controlling the presence of bacteria and waterborne disease.
