Mexican national water authority Conagua will tender two potable water projects worth 2.27bn pesos (US$194mn) under the Sonora Sí water management program in the coming months, the authority said in a release.
Sonora state water authority CEA met with Conagua director José Luis Luege on Tuesday (Jul 12) to discuss the program's progress.
The first phase of the Revolución potable water pipeline will be tendered this month and is expected to cost some 570mn pesos.
The project aims to improve potable water in cities Navojoa, Etchojoa and Huatabampo in the southern part of the state, which are currently supplied by an aquifer with high levels of manganese.
CEA will also tender the construction of the Centenario dam this month. The new dam, with capacity of 4.7Mm3, will supply water to 15,000 people in Nacozari.
Investment in the dam project will run to more than 1.7bn pesos.
The modernization of irrigation in the Mayo valley is also included in the Sonora Sí program, which will allocate 540mn pesos to recover 174Mm3/y of water. CEA expects to invest 90mn pesos in the project during 2011.
The Sonora program also includes construction of wastewater treatment plants in Nogales, Navojoa and Hermosillo. Tender schedules for these projects have yet to be set.
