All drinking water treatment plants (WTPs) must dispose of their potable water residuals. One privately owned water utility in Fairbanks, Alaska, uses a filter press to dewater its water treatment mineral byproducts. By doing so, the utility achieves zero discharge to the nearby Chena River, which serves as a recreational area and spawning ground for several fish species threatened with possible extinction.
