Spotlight: The tenders for Mexico’s US$100mn Yaqui aqueduct

The Mexican government began implementing a plan this year to build the 2bn-peso (US$101mn) Yaqui aqueduct in Sonora state, a water distribution system comprising five projects to deliver 200l/s of water to 50 indigenous communities.

According to its cost-benefit analysis in the finance ministry's (SHCP) investment portfolio, the projects include an intake work at the existing Oviachi dam, a more than 180km-pipeline network that will be divided into two pumping pipelines and two gravity drive lines, a water treatment plant, a regulation tank and water delivery branches. 

Water authority Conagua has launched and awarded five construction tenders for the pipeline network. Meanwhile, construction contracts for the plant and intake work are set to be awarded before year-end, according to records on procurement site Compranet.

BNamericas takes a look at the current status of the tenders.


Conagua received five bids on November 2 ranging from 140-190mn pesos for the construction of the intake. The winner will be unveiled on December 16, according to the tender (LO-016B00985-E226-2022) documents. 

The authority also received nine bids ranging from 4-9mn pesos for supervising the works. The winner of this tender (LO-016B00985-E237-2022) will be presented on December 16 as well. 

The intake will extract 212l/s from the Ovichi dam at a height of almost 50m, according to the cost-benefit analysis.

At the same date, Conagua received 14 bids ranging from 4-13mn pesos to supervise the project’s construction. The naming of the winner is scheduled for December 12.
