Officials with the Santa Cruz County Emergency Operations Center received an update from the United States Section of the International Boundary and Waster Commission (USIBWC). At 2 a.m. on August 2, crews in Nogales, Arizona completed installation of a bypass system to divert sewage that had been leaking from the partial breach. The sewage is now being conveyed for treatment at the Nogales International Wastewater Treatment Plant and is no longer flowing into the Nogales Wash.
The United States Section of the International Boundary and Water Commission (USIBWC) is investigating a leak from the International Outfall Interceptor (IOI) and is participating in the repair of leak. The leakage has been identified as occurring at manhole 89 which is approximately seven miles from the International Boundary. The IOI conveys the City of Nogales, Arizona’s sewage along with Mexican sewage to the Nogales International Wastewater Treatment Plant in Rio Rico, Arizona.
