Mexican national water authority Conagua has shortlisted three bidders to build and operate the El Zapotillo-León potable water system.
The first shortlisted consortium consists of Controladora de Operaciones de Infraestructura (Canoisa), Servicio de Agua Trident and Acciona Agua, while the second is formed of Abengoa México, Befesa Agua and Abeinsa.
The third bidder includes Korea Water Resources Corporation, Samsung C&T Corporation, Samsung Engineering Company, Techint, Techint Compañía Técnica Internacional, Techint Chile, and Constructora y Pavimentadora Vise.
Another three consortiums had prequalified for the tender but failed to submit the necessary documentation, according to a Conagua release.
The water authority published the tender to design, build and operate the water transfer system in December 2010.
The El Zapotillo pipeline will have capacity to produce 3.8m3/s. Other works include construction of two pumping stations, a water purification plant and a regulator tank.
The project will require an estimated investment of 5.36bn pesos (US$462mn).
The reservoir and water transfer system will supply an estimated 2.5mn people in Jalisco state capital Guadalajara and León city in Guanajuato state.
