The following is taken from a “council communication” from Public Works Director Pawan Agrawal providing background information regarding the agreement between the city of Bullhead City and the U.S. Bureau of Reclamation permitting the city to pump effluent — wastewater — into the Colorado River: In October 2014, the U.S. Bureau of Reclamation issued a letter inviting certain entities along the Colorado River to participate in the “Pilot Program for Colorado River System Water Conservation” they developed at that time, and Bullhead City received this invitation.
