Mexican national water authority Conagua will support a 227mn-peso (US$16.2mn) water infrastructure program for the Yaqui tribal area in Sonora state, according to a release.
The plan aims to improve potable water access, drainage and sanitation. Projects include building potable water and wastewater treatment plants, providing well- drilling equipment, pipeline maintenance works, drainage networks and the rescue of wetlands.
The authority also plans to re-line the area's main water canals to prevent water loss.
Agricultural producers in the Yaqui valley area have been some of the most vocal protestors against Conagua's Independencia transfer pipeline project, which they say will reduce the availability of water for irrigation.
Sonora's Yaqui valley is home to some 55,500 indigenous people.
