Sonora and Conagua Sign 11.5 Billion-Peso Water Plan to Lift Hermosillo Supply by 15%

The pact shifts into funded planning with early construction expected in 2026.

Overview

  • - The state and federal governments formalized a 11,537 million peso program that targets urban supply, farm efficiency, sanitation, and flood control across Sonora.
  • - For Hermosillo, officials set upgrades to the El Molinito dam, a 13‑kilometer aqueduct, and completion of the Norte water treatment plant to add about 500 liters per second of mostly surface water.
  • - Leaders said the plan will finish the stalled Nacozari dam and build a new dam at Cerro Colorado in the Mátape basin to curb floods that affect Guaymas and Empalme.
  • - Agriculture funding totals 6,500 million pesos to modernize irrigation in the Yaqui and Mayo districts, with an added push to technify 1,500 hectares in Ures.
  • - 2026 work includes 595 municipal projects via social infrastructure funds worth roughly 670 million pesos, 400 million pesos for Arroyo Los Nogales, and more than 30 treatment systems on the Sonora River, addressing losses and aquifer stress that officials say stem from heavy well use and leaky pipes in Hermosillo.
