High temperature can disrupt treatment plant operations.

King County prohibits discharges with temperatures above 104 F (40 C) when they reach the treatment plant, or hot enough to interfere with biological processes. Industrial wastewater must not exceed 150 F (65 C) at the point where it enters the public sewer system.
