Service is great! The way things are handled, it’s like my problems became your problems…and the way in which things are handled by you, it is as if problems don’t even seem like problems.
DESCRIPTION
Chukchansi Gold Resort & Casino is ideally situated approximately 40 miles north of Fresno, California and 20 miles south of Yosemite National Park. Owned by the Chukchansi Tribe, they offer a 420-room lodge (expanding by 214 rooms by 2010), 56,000 square feet of casino gaming, seven restaurants, and nightclub.
The MBR plant, capable of treating 250,000 gallons per day, was commissioned in January 2008. The treated effluent flows into nearby lagoons; however, future water reuse includes utilizing the treated effluent for irrigation purposes around the casino, lodge and other facilities. Sludge is treated by an aerobic digester, and then sent to a belt press for dewatering.
